I was at a nighttime forest stage, Wales, 1985. Freezing cold, 1am, pitch black, punctuated by each car going by, noise, exhaust, kilowatts of lights, flying gravel. Those few hours have never left me
Went to a night stage in North Yorkshire before, a bad crash happened in the day stage that day and unfortunately a co-driver died so people went home. There were only us and the Marshalls on the entire night stage, pitch black, deep in the forest.
@@andyxox4168 Rally headlights are over 100w (in the 80s) Each car would have maybe 6 or 8 for a night stage. Times the 30 or 40 cars that went past…..? Kilowatts
@@HT-io1eg nope, 2 headlights were allowed which had to have max 65W headlights and then a maximum of 6 spot lamps usually with H1 lamps of 100w (which were not road legal!) so that would be 730W total.
@@andyxox4168 Semantics aside, if you're leaning on a tree in the middle of a forest in the dark with only a head torch and the lume on your watch besides the dark indigo of the night sky, a fully lit up rally car flashing through your vision feels like a storm passing by you.
Hannu Mikkola's audi quattro was Restorated here in the west side of Finland not too long ago. My dad was asked to make New seat cowers for the old ones and he obiously agreed. We (basicly all the member in our family) went to the garage where the restorated audi was kept. I was really young back then, but i remember really clearly when the garage door was being lifted and the groub B legend began to slowly show itself. I won't ever forget it. Dad took the seats and we stayed there like an half an hour just looking at the quattro. When we finally got home dad suddenly called them and asked that can he take a small part of the drivers seats main fabric. They agreed an dad took about 3x4 cm peace of the seat fabric and gave it to me. I remember being so SO happy about it. Dad made the seat cowers and gave them to the guys at the garage and the seats are in the quattro right at this very moment in Hannu Mikkola's personal garage and the peace of the old seats cloth is on the wall of my room inside of an audi quattro s1 photoframe. I am so proud to be my dads son. Sorry for the bad english.
Some Group B are still racing in Classic Rally events all over Europe...just this weekend they did so in Portugal to celebrate the 50th anniversary of the WRC
I agree...i saw these group -b monster few times back in the 80's, in the Thousand Lake rally, and they were so incredibly loud, no matter how far from the start you were, you could always hear them coming...all the way from start..
Audi -driver Hannu Mikkola ones said, that when Quattro S1 was taken to the absolute limit you reach some kind of tunnelvision where the landscape in your right and left just dissappears. While flying thru the multiple jumps on these gravel roads in high speed you are not simply a driver anymore, you are a pilot in an aeroplane flying very, very low indeed. Almost unlimited power combined to the chassis and suspension of that era - it must have been a hell of a ride.
When I play dirt rally Finland is always super fun but if you make a mistake you are royally fucked. Wales is also really damn bumpy for no damn reason. Those two will fucking kill a great season(in game)
Hi, the 'little thing' you mention in the beginning is a Opel Manta :) Walter Röhrl, german Rallye Legend was telling about the Audi Quattro (short wheelbase) that this car was hardly driving one meter strait :D Another qoute from him, beeing asked when a car was fast enough : 'When you enter the garage and you are afraid to lock it on.... Great driver, great qoutes ! Btw., the Quattro had up to a 1000 hp in the 80's !!! This was possible cause there were hardly any technical regulations in Group B. What a time !
2:00 - They all sounded different because of this: - Audi: 2.1L turbo inline 5 - Peugeot 205 T16: 1.8L turbo inline 4 - Lancia 037: 2.0L supercharged inline 4 - Lancia Delta S4: 1.8L turbo + supercharged inline 4 - Renault 5 Turbo: 1.4L turbo inline 4 - Metro 6R4: 3.0 N/A V6 - Toyota Celica: 2.0L turbo inline 4 - Ford RS200: 1.8L turbo inline 4 - Opel Manta 400: 2.4L N/A inline 4 You can see that some have the same engine configuration but there were other differences that explain the different sounds of similar engines. 3:03 - The Opel Manta 400 was not that little, it was approximately the size of the Audi or the Toyota Celica (and this answers your 3:40 question). 😉 5:10 - Well, I can (two Rally Portugal "under my belt": 1984 and 1985) but the sounds, the smells and the whole experience is impossible to describe in words. Disclaimer: I still have all my fingers. 😄
@@stevegraham3817 - My objective wasn't to make an extensive list of Group B engines, just the ones shown in the video and a few other that might pop up in other videos Ian watches in the future.
Or it could have been a NA 2340cc and later 2391cc FJ24 built into the BS110 platform. 2L engines, turbo and non turbo, were released in the standard production car models. DR30 Skylines, Gazelles, S30 Sylvia, and possibly others. FJ24 was only in Group B and sold as engines only, some in semi factory arrangements. Check out George Fury's Australian Group G (Oz equivalent of Group B) Datsun 120Y.

A shame that the Metro 6R4 wasn't there, such an awesome tiny car with a fantastic sounding big V6. Last car being the Delta S4, you can hear the crazy turbo/supercharger combo. And gotta throw some love to the Peugeot - most successful group B
Finnish rally is the best rally of the world, and up until the early 2000's Finnish drivers basically dominated the sport. And it was the Group B where Finns shined the most, by winning the titles almost every year: 1983 Hannu Mikkola (Audi Quattro) 1985 Timo Salonen (Peugeot 205) 1986 Juha Kankkunen (Peugeot 205) Other honorable Finnish drivers from that era to mention would be Markku Alen, who drove Lancia S2 (rear wheel drive) and S4 (four wheel drive), and was holding the championship title for 10 days in 1986, until it was taken away from due the Peugeot's protest. His teammate Henri Toivonen was considered to be the all time fastest driver, and he was dominating the early season of 1986, until he crashed is S4 in Corsica and lost his life. That crash was initially the end of Group B -era.
Probobaly the greatest rally driver Walter Rohrl would disagree on the "greatest rally" as he said I don't like that rally because if I want to fly I would be a pilot not a rally driver. Funny part: he is a pilot as well.
@@altergreenhorn Röhrl might have been the most arrogant rally driver of his era, stating that he himself would be the best of all, but honestly speaking the greatest driver ever lived is undeniably Sebastien Loeb with 80 rally wins and 9 consecutive World Championship -titles. Anyway, there has been public polls about the best rally of the world, and Finland has won it more often than any other rally. It has more speed, jumps and challenge than any other rally. But of course this is just a matter of opinion. I personally love to see cars going 180 to 200 km/h and flying (literally) to the corners, instead of watching how drivers try to avoid flat tires while doing 60 km/h in some ox road.
@@Ilmarintarina Röhl is the greatest allround driver and can do things what sebastian leob or Sébastien Ogier( 2 of the truely best Rallydriver of all Time) can´t do. Search for MOTORSPORT : WALTER'S COURAGE l A NIGHT TO REMEMBER IN ARGANIL , imagine 4min 59sec faster as the secound fastest in the night and with fog on one stage
I know I'm late to the party, but at 11:55 those two are the Opel 400 again, and the Lancia 037. If memory serves, they were two of the last cars in Gp.B with RWD instead of 4WD. And yeah, they were both *perfect*. I'm a Road Racing Boy, but I'm from the Southern US and still go watch dirt oval from time to time. :D
I attended a few Group B events in the UK in the early to mid eighties. You used to hear gunfire like sounds coming through the trees minutes before the Quattros turned up. I was working for Audi at the time so I was quite invested and used to feel a fair bit of pride. My old boss used to do classic rallies and he let me drive his ex Hannu Mikkola Porsche rally car once - fun times.
Wow,amazing story..but i kinda dislike audi for that pr stunt they did in Germany when Misha Charoudin helped the people that were hit by the flooding in 2021 with that audi rs6.. I assume that Audi in UK is far grate managed !
Growing up in the '80s and through the '90s (10-20 years-old), and being into cars and racing from an early age, I still, to this day, get so energized when I see this stuff again. The Audi did it for me. 5-6 years-old watching them things, and then later I went to Lincoln Tech for Auto Tech, then off to UTI VW/Audi specialty training. Problem is that racing and Rally is what I really wanted, not working on cars. Now I'm 42 and thinking of doing some rally training, mostly to pursue for mere pleasure. I sometimes wonder if I am too old though. ???
The 1,000 lakes Rally, also known as Rally Finland, has been running for 70 years. It was first held in September 1951. The Ouninpohja stage, where some of this video was likey recorded, is renowned for it's high speed corners and jumps. In 2003, Markko Martin set the record for the longest jump at 57 metres, while travelling at 170km/h.
Just to help you out with a few questions you had: - many group B rally cars still remain in the possesion of museums, their manufacturers, or private owners. Some are raced to this day at historic rally events, most notably at the Rallylegend held in San Marino every october. That event is a huge video recommendation! - about maintenance and repair. A year in the world rally championship consists of 12 rallys usually, so one per month. There are some powerful rally cars, but an engine should last at least half a season, or even an entire season, because they are built to last. Most rally cars are tuned up street cars, and there are strict power restrictions, so they would never be so powerful as to fall apart or need a new engine on the regular - servicing the cars druing a rally is strictly regulated. Usually twice a day, every 5-6 stages or so cars can go to the service park, where they have a time limit, usually 60 minutes or so to be serviced and repaired. If the team can't do it in the time given, they are heavilly penalized, or can be even disqualified. There are also refueling points along the way, but doing anything to a car is prohibited between stages, and only the driver and codriver can do repairs, if they have a problem on a stage. There are very good examples in "WRC Craziest Moments" for this
"there are strict power restrictions" This is group B we're talking about here though. There were displacement restrictions, but no restriction on boost.
yeah the group B engines would literally melt after prolonged running infact I think it was the FordRS200 that would only last 12 minutes. Basically formula 1 on dirt new engines every weekend
Indeed, Group B was a way higher level of tuning, and components didn't last that long, I just wanted to give a more general approach as well, he asked about this, if I'm correct. Let's not forget though, that rallies consisted of 40-60 stages sometimes, so along with all the power, the cars had to be reliable enough to complete a day at least.
Yeah. Sometimes they changed engines after every stage, most parts of engine surely. And also group b have nothing to do with street cars. they were mostly mid-engine cars compared to normal street car counter parts that had front mounted engine. They were basically just fiberglass bodykit on tubechassis.
@@Viperguy88 "usually 60 mins or so". Is that long enough to scrape the co-drivers poo off the roof? Thanks for replying with all that great information, much appreciated! 🏁🚗
As a Kiwi in my late 50's, I got to watch the Group B monsters in action. Unforgettable sound of the Audi's, coming through a freezing cold pine forest stage. Here I am in 2022, late last year, I bought a NZ new 1990 Audi 90 Coupe ( grandchild to these beasts), non turbo, all original factory manual, service record, original mags, tool kit. The closest I will ever get to my memories, and an end to a 10 years + search for piece of Rally history.
9:00 The components were designed to last the whole season. The cars were meant to be based of their road-going counterparts (which obviously had to be lifetime reliable). But due to the occasional “off” or crash, powertrain and drivetrain tear-downs might become necessary, situationally.
@@EforEki .. Except for the Lancia 037 where they made 200, showed the FIA 200 in the morning, then had a good lunch on the way to show them ‘another’ 200 at a different location. And no, the cars didn’t last a season, they were fully rebuilt after every event, sometimes during an event!
that whistle on the audi i do believe its when the turbo disengages and the supercharge kicks back in at the low rmp and take a huge breath of fresh air
the audi only had a turbo i think it was because they did not have a dump valve so when letting of the throttle you hear the surge of the turbo pusching against a closed throttle body
As the great Walter Röhrl ones said..."while acceleration, the tears of emotion must drain off horizontal to your ears"...."if you can see the tree you crashing in, your car is understeering. If you only hear it, your car is overstreering"
@@psynque No he was smart. Therefore he is still alive. Rally was much more dangerous back in the days. By the way, our opinion regarding Walters skills is absolute inconsequential. Only the opinion of other World class race drivers count and all of them consider him as one of the greatest of all time.
@@lancemurdoc6744 No they don't lol. Maybe "one of" but you won't find a a Rally B contemporary that calls him the greatest. He was a coward, picking tarmac stages he could drive and his car was good at.
Answering to 7:37 question, in San Marino (close to Italy) there is an event called “Rally Legend” on which a lot of historical and modern rally cars compete, sometimes driven by the rally drivers from that era. It is just a spectacular show and every year you can find some original group b cars driven sometimes at 60-70% of their power which is a lot considering that those are incredibly expensive right now
01:35 That noise of the Audi comes from the Watergate - The wastegate is a valve that controls the flow of exhaust gases to the turbine wheel in a turbocharged engine system. 03:02 This little thing is an Opel Manta 400 Group B 03:39 yes its a Toyota Celica TCT
correct... those are the beautiful noises that an internal wastegate make. my datsun used to make similar noises but a little deeper note, really makes you want to spool that turbo up just to hear the sounds lol.
The Audi noise is flow reversing through the compressor stage (transient surge). Everyone calls it wastegate noise, the noise of a wastegate is just excess air flow from the turbine/exhaust and just sounds like a jet engine roaring, very different noise. 🙂
In Spain when it's rally season you can see them running after the actual rally cars, not as serious as back in the day of course and most of the time they just do the track slowly, but some of the drivers like to show the cars and give a bit of show, either going fast or doing some donuts. It's a nice experience overall, and it's totally free :D
Had the pleasure of seeing the Audi S1 up close at the Australian stage of the WRC here in Coffs Harbour NSW a few years ago. And yes, in person the sound is glorious. That particular car races under the Historic category.
wow, so lucky man..when will be another race in Australia..i really want to see a rally race there..here in Europe is beautiful..but in other continent specific Australia with his cool landascape i think it's so amazing:) going flat out If you know any schedule for sure i will come:) Australia and New Zeeland rally scene i assume are amazing
EX Group B cars are constantly compete in Historic rally races the little loud car is Opel manta B400. Check out topgear UK's video about the battle between audi and lancia
@@bricktop2603 also the campeonato de rally historico de españa (spain historic rally championship), even there are some regionals Championships of this! I attended one last year and it was insane
The Lancia Delta S4's still are around, driven by Bruno Ianniello. He competes in Swiss/European Hillclimb Championship, you need to see this hillclimbs, they are like Pikes Peak. :D A lot of European classic cars are competing in this Hillclimbs, Audi S1, Lancia Delta S4, Renault 5 Turbo, prototypes, Formula cars, touring cars etc. For Example St.Ursanne Hillclimb in Switzerland, i was there it was awesome. ;D
About the end of Group B cars. After they were decommissioned, for quite some years they toured around Europe in "Rallycross" events. They were so famous that people filled the circuits just to see them in action. I went to a couple of them. This is a collection of silent Super 8 film on the 80's in that circuit. Check it out, you will see some second hand Group B's running there... th-cam.com/video/smRiD2umapw/w-d-xo.html
That chirp that you're hearing off the Audi is an early jab at an anti-lag or recirculating turbo system. Instead of dumping the extra air pressure just into atmosphere when the throttle is lifted like with a BOV, this system instead purged the air into the hot side of the turbo system in order to attempt to alleviate the time spent building back into boost. This not only allowed for a snappy turbo system that mostly did away with the lag created by early large single turbo systems, but allowed Audi to use a smaller displacement engine which revved much more freely and fit class requirements.
no it isn't its compressor stall as they didn't bother to use dump valves to make the turbo bearings last long it just needed to last the stages and get replaced.
Most of the remaining group B all entered European rally cross where they all gained even more power. They reached their maximum potential. Martin Shanker was Mr Rally Cross. Get into mid to late 80s rally cross. The value today of all those cars on the starting grid is mind blowing
2:56 that's an Opel Manta 400. As an American, you might have heard of the Opel GT. The Manta was a coupé derived from the Opel Ascona B, a family sedan based on the H-platform from GM. In the US, on the same platform, in the 70s you got the Chevy Vega&Monza, the Pontiac Astre&Sunbird as well as Buick Skyhawk and Oldsmobile Starfire.
Yes, Flamebeard, Ascona / Manta 400 were highly modified. The engine was developed with Cosworth and car with Irmscher. At the time I had a Manta 2L but wanted a 400, budget & wife blocked that.
@@boerharms2209 Excellent, I had a 2.0 SR Berlinetta coupe. When the 2.0 GT/E came out it was not enough of an upgrade to justify a big cash outlay. When the Astra 2.0 GT/E 8V was better and the 16V (red top) is the motor Manta deserved. I sold mine and bought a Chevette HSR.
@@russcattell955i ahh cool! ive got a 2.0 8V CIH Manta B1 (with chrome bumpers) and dual weber setup, and a B2 that will be receiving the 16V engine once the car is done bodywork wise.
@@boerharms2209 Nice, I imagine the CIH would be tasty with dual DCOE's. In it's day, Manta had a great chassis. I recall having fun with a mate in his Sierra XR4, he was faster on the straights but could not keep up on the twisties, I had 205 tyres & Monroe fast road dampers.
Hard to beat the raw wail of a turbo 5 cylinder engine as in the Audi. Volvo 850 BTCC car also had a 5 cylinder and sounded like the bowels of hell. On a side note, you look amazingly like Valteri Bottas. Keep it up.
Had the pleasure of a ride in an escort rs200 rally spec. 700bhp, but was detuned to about 350bhp due to race regulations. It was mental. I'll never forget that drive!
@@andyxox4168 it was an evo2 so yeah that powerful max out, but as I said detuned for race regulations and I guess, reliability ! The race regs in the UK rallies were a lot stricter in 2012 than they were in the late 1980's
I've seen videos of hill climbs just few years ago where some group B cars participated. My favorite engine noise of all cars that existed or exists is the sound of the Audi Sport Quattro S1.
In 1980s I had a leading rally driver from Finland beside me on a connecting flight from Sydney to Melbourne, sorry do not right now recall the name. He spoke with me in moderate English, but was more fluent in German so we continued in that. He was about to take part in a series of rallies in the Victorian mountain forests. On noticing we were flying over parts of the area He was about to be rallying in I started describing the places, mountains, vallleys as we passed over. He was so fascinated to see the country from high up. He thanked me profusely for the opportunity to see his rally destinations that way. He offered to have me visit his rally base and view so rally live. I sadly was just returning from Europe to get into some fuel injection test trip work, so was unable to have time to take up the offer. He remained very thankful. We parted in the airport baggage claim area. (Name might have been Rinkonnen or similar, but I may also be mixing up with other racing names)
i saw these beasts live in Finland back then...recent cars are loud as well but these you could hear from miles away...just the sound gave me goosebumps...and when they passed by..you kinda had to turn your back to them because of all the dirt and sometimes big stones flying towards you..but still..great fun
Men among boys? They always said that about group b but then there was our homie Michele. Michele Mouton has an Audi Quarto trim named after her from her time in group B. She has a win at le mans as well, in the two liter class. She also hit up pikes peak before Rohl did.
Grup B had amazing cars Lancia, Peugeots 4x4, bi-turbo, Audi 4x4, you name them. The raw adventure for a Fan was to be there, in the "first tow", exposing yourself to the flying comets. Rally Pilots were and are the cream of the top! Narrow, snowy or dirt roads, often flying through the air, left-and -right curbs and turns, alive and moving walls of Fans on both side of the roads. And the co-pilot or navigator instructing the Pilot ; Left turn hook, 45 degrees, followed within 12 meters by a 65 degrees right turn, immediately followed by a 4 meters jump... ", Nerves of steel, reacting like a falcon r a tiger.... Races like a 500 Miles, in a closed circuit, featuring only 4 identical curbs to the left are kind of boring. Give me a Great European Rally, or Pikes Peak in Colorado -- there it's possible to admire skills, guts and fabulous cars and drivers.. Thank you for another fantastic Video
4:35 : For us, it's Group B rally madness. For a Fin, it's Monday morning and they're late for work... And yes, there's a real disparity in where really talented multi-surface drivers hail from. 7 out of 10, it's a scandinavian country.
IWRocker, you're doing a great job! To answer a question you asked within the the video, "the angry little car" you mentioned was an Opel Manta 400. Opel is GM in Europe (Vauxhall in GB), and the Manta was a total RWD beast producing 270 HP with its atmospheric engine - no turbo boost! The one you saw in video was propably driven by Ari Vatanen, or the the late Henri Toivonen, judged by its livery. Though the Manta was cannibalized by the 4WD monsters in the WRC, it was hugely successful in many national championships, including the glorius British Open Championship which was regarded as the second best rally challenge in the world, back in the day. The Manta 400 has produced many national legends who have also shown WRC success, while the Group A version Manta 200 has been a career making car for many rally heroes in the making. Manta was favoured for its simplicity and power by the drivers, while spectators where awed by its spectacular sideways looks. You may be interested in SimRacing UK's amazing "Manta Magic" videos th-cam.com/video/7xwukmsJE8g/w-d-xo.html All the best
Great reaction mate, so good to see you enjoying this! Sorry, I can't answer any of your questions but a couple of things you said in the video made me think you might find it interesting to check out Michèle Mouton. She, and co-driver Fabrizia Pons, were women among the 'men among boys' when they placed second in the 1982 World Championship (in a Group B Audi Quattro). Mouton also performed some of my favourite Group B 'perfect drifts' caught on film when she set the outright record at the 1985 Pikes Peak Hillclimb.
The car you admired at 11:56 is an Opel Manta, two wheel drive and naturally aspirated. A wonderful drivers car. The next car was also two wheel drive Lancia with a supercharger. Both Opel and Lancia have won World Championships with two wheel drive. Many people think four wheel drive is what makes these cars fast but it is just one factor. Turbocharging added huge HP and then the 4x4 were able to exploit that extra traction. On pavement two wheel drive still works very well.
Thanks dude! I saw them many times live, actually every Jyväskylä Rally. My father was a petrol head so it was our tradition. Finland has more rally world championships than any other country. Actually last weekend Kalle Rovanperä won the Portugal WRC-rally. At least the Finnish group-B drivers, which were many, have these cars in their personal collections. And some of them are still "racing" in different classic-car races. Or hill climimg etc. If you wanna see something funny, watch Ken Block testing Audi-B cars in a secret Audi facility in Germany. It was his childhood dream.
That flutter noise in the Audi was the wastegate opening and dumping exhaust for the turbocharger that car was making 500-600 bhp. The Lanica Delta car was making 500 hp with a compound system with a supercharger feeding a turbocharger... from a 1.8L engine in the mid-80's!!! Rally cars might be faster now but they aren't driving them on the ragged edge.
A recommendation: try watching European hill climb highlights; crazy fast cars on tight public roads. A favourite of mine is the Prospeed Audi S1 (around 800 HP) - fantastic sound. Loving your racing reactions!
Min 3.00..."that little thing" is a Opel Manta B400! In 1982 they were fighting for the world championship! A 2,4 liter with about 280HP and less than 1 ton. RWD
Also fun fact, that rwd car that did the perfect drift may look familiar ( the opel manta 400 ). Its a similar bodyshell to the 80s style Holden commodore.
I remember attending the circuit of Ireland rally back in the 80`s and to this day I will never forget the sound of those Audi Quatros going past with flames gushing out every gear they took. The Metro 6R4`s were something else too.
@@Derry_Aire in track yes, in road no. the 1st ''flying finn'' in the road are: Timo Mäkinen, Rauno Aaltonen and Simo Lampinen . check timo mäkinen in mini cooper S and bonnet/hood. when driving hood up and despiced that he finished just 3rd in that track. and won whole rally
1:50 when you take your foot off the gas, the still-spinning turbo presses the air against the air vane (translated by deepl), which gives way at a certain pressure, thus opens briefly and lets the air out, producing this repetitive sound by rapidly opening and closing and opening and closing and so on. this ruptures the turbo-bearings in time, so a waste-gate was introduced, which short-circuits the air-flow at negative pressures, making the typical hissing sound you can hear nowadays.
My family and I live in Turin, where back in the 70s and 80s the Lancia Squadra Corse was based. My dad went to school in the Lancia technical institute, which was in the same building where squadra corse used to build their car. Every time we talk about these times, he tells me how glorious the engine from the Lancia Stratos and 037 used to sound on engine test bench, where they were pushed to the limiter for hours, until the breaking point. Also, coming out of school, seeing all the cars being lined up outside the building was just incredible, you could smell the racing atmosphere around that place…
That Lancia Delta S4 you had as the last clip was actually a 1.8ltr Turbo charged and Supercharged. Lancia did that so the Supercharger would eliminate any Turbo lag that was associated with these beasts. Great video mate.
If you like to know more about the insanity of the rally sports, you might like to take a look at 2 events: The pikes peak race in 1987 where Walter Röhrl came to Colorado with his Audi quattro S1 and The famous night of Arganil in Portugal 1980 .where Walter won a night special stage over 42 km (26 miles) 4:40 faster than the second place.
@@harshithsadhana7475 I was not aware that Madame Mouton was there (at Pikes Peak) already 2 years earlier to win the race in 1985. (There is always something new to learn)
Even today, at least in France from what I can tell, there is a category for older cars called VHC, Véhicule Historique de Compétition (historic competition vehicules) but not often you gonna see Audi S1 or Peugeot 205T16 considering they cost probably over a half million 😅 But yeah you can still see older cars in these events
Rallying makes F1 look boring. I was lucky enough to be a Press photographer for the British Internationals (Scottish, Wesh, Mintex/National Breakdown and RAC rallies) covering the late seventies to late eighties. I saw the change from Ford Escort dominance to Quattros and then Group B. Fabulous days.
When Group B ended, you could find these cars being used for Rallycross as well as hill climbs. We still see them racing today in historic rally events and classes.
The quattro s2 e1, manta 400, delta s4 and 205 t16 evo2 are probably my favourite ever cars.. and not just rally cars.. cars in general... absolute masterpieces of engineering!!! The flutter on the big winged audi is actually compressor stall from the turbo due to running hardly any wastegate at 650+bhp so the turbo actually stalls (many people call it the blow off valve, but they didn't run an external blow off valve..the blow off valve recirculated back into exhaust system) its pretty much the back pressure of the air pressure generated causing the turbo compressor wheel to stall
I saw a old group b driver takes the quattro out a couple of years ago and they put one camera on the pedal box and one camera on the gear Stick it was insane to keep up with what I was watching
A lot went into collections, but also something called Rally Cross a circuit event when they would drive a short circuit on loose surface & tarmac. They ramped the power up even more the Lancia delta, with over 700hp. Closely followed by the 6R4
The angry car was an Opel Manta. And the drift into corners is known as The Scandinavian Flick. They are taught to do it during driving lessons to achieve a driving licence because of constantly adverse road conditions in winter.
To answer your question regarding the stututu noise from the quattro. It's actually just the noise of compressor surge. Typically it'll happen when a turbocharged car either produces too much boost for a BOV to keep up with when letting off the throttle or when a turbocharged car lacks a BOV entirely. Where in letting off the throttle closes the pathway for the boost to enter the motor and is sent back through the intercooler and intake piping and back through the turbo in reverse which still has the turbine spinning clockwise. Making the iconic stututu fluttering noise.
The hissing of the Audi comes from the intake of its turbocharger. As the throttle gets closed at high revs, the turbo still is spinning fast under its impetus but the flow through the centrifugal compressor is reduced drastically. Like when the wing of a plane stalls at high angles of attack, the airflow on the compressor wheel's blades gets separated. As the turbocharger spins down the pitch of the hiss drops audibly.
To answer your question about the squeaking and chirping noises ...You have to remember that during this era, there really wasn't any computer stuff on cars yet so all the "go fast" modifications were mechanical. A few teams had sequential shifters by this point, but no paddles as it was a huge lever in the center of the car. The noises are the turbo waste gates...the diverter valves have been removed as it helped with boost pressure re-build after lifting off the throttle. Lag was a HUGE issue during this time frame...So to go back in history: turbo charging came about during WW2 on fighter planes...some were supercharged AND turbo charged. Turbos were first adopted to Diesel engines and I believe it was Porsche who first brought the technology to gasoline race cars with their 12 cylinder Can Am 917 racers in 1972. These were not intercooled at that time but still made a mockery of everything else in the field...from 72 through 74. The "gas crisis" of 1975 brought an end to auto racing in the US for a year and a half. Glad you're digging this...!
7:20 Nowadays, in rally events, there are presentations of classic cars., included Group B cars. Spectators will be able to see the vintage cars up close as they race. European public love Group B cars.
Events used to be up to a week Long and about 3500 miles with about half as stages. Army's of mechanics and service vans had to set up service parks in wayside stops all over the place. Motors generally where tuned up to the max that is possible to get thru the event.
Here in Europe they still race in special events, exhibitions and historic rallies. Lots of people are even doing crazy restomods of these monsters. The most noticeable being the Kimera EVO37 based off Lancia 037
Some group B stills racing on a regular races. In regular races don't matter who goes faster, but who do the most regular time in the laps. There are some special Rallyes for the classics cars like group b.
The chirping noise is off throttle surge. Caused by the throttle closing, which in turn reduces the airflow of the compressor (compressor map point moves left) so that the surge line is exceeded on the compressor map for that combination of compressor speed and pressure ratio. The compressor cannot supply the air flow for this pressure ratio, so the compressor speed and pressure ratio reduce until the compressor can again sustain the pressure ratio and airflow. The compressor speed then increases, increasing the pressure ratio to the point of surge. This happens many times a second giving the chirp.
IWrocker, if I had enough money, I'd turn up at your door and take you to Finland to watch WRC, you're one of us now, by that I mean rally is your favourite motorsport. Love your reactions, the fact you know when the audi is coming shows you're a true fan.
Rallies take place over Friday, Saturday, and Sunday. The cars have to drive on public roads to get from one stage to the other. Some stages, have a full mechanics team to repair and prepare for the next stage. Some stages don’t have any crews, and it’s up to the drivers to do the repairs themselves.
Audi rally cars were called as snowplowers cause of the front spoiler. goodwood festival of speed in UK, hillclimb events, historic rallies- these are events you can visit to see the cars. even collectors and some factory teams do make some appearance in these events.
Lot of cars were used for rallycross and some are in museum or became collector pieces. There are also enthusiasts who are making replicas and so on and rally those as privateers. There is so much rallyes going on nowadays and sometimes if You are lucky enough You can see f.e. GrB Audi storming the stage as safety car. Just insane!
To answer your question - they often appear at the Goodwood festival of speed and in historical race events, most of the cars though spend most of their lives in private collections and museums,
David Llewelyn a quiet welsh guy drove a 6r4 metro like a madman and when he was interviewed about it he would say he’s going so fast and looking so far ahead he had to judge where the road would be by looking at the trees not the road, insane power 😎✊
The car that blew your eardrums is a Lancia 037. A rally is mostly a few days and after each day they are allowed service and broken things get replaced then. But it's all time restricted, so they only have as limited amount of time to do it. I also believe that it is restricted/limited at what you can repair/change with each service, like engine and transmission. Some mechanical from rally's crews (and other motorsports I gather) can change a transmission in about 7 min.
3:00 Opel Manta B 400. I used to have one. Well, not the 400 variant. Mine had a 2-litre four cylinder with twin dual 40mm Dellorto carbs, different camshaft and a tube header. It wasn't tuned for max hp, it only made about 140hp on dyno (40hp over stock) but it was a nice, streetable engine. The car only weighed ~2250lbs so it went fairly well. 4:35 The Finnish rally has traditionally been known as the Grand Prix of gravel roads. It's the fastest rally in the WRC calendar.
The chirping sound from the audis are chockwaves from when the turbo goes from full charge (full gas) to let go of the gass (less/no charge). It only happens whith a certan ratio between turbo house and plenum chaimber. You can hear it on some of the saabs 16 valve too. Fun fact: scandinavia has produced the most number of highly ranked rallydrivers in the world, in relation to size of the countries. Finland has the most, fex: Tommi Mäkinen, Hannu Mikkola, Ari Vatanen, Marcus Grönholm, Markku Alen to name a few. Other worldclass drivers are Stig Blomqvist (swe), Björn Waldegård (swe), Eric Carlsson (swe), Andreas Mikkelsen (nor), (Greta Molander (nor), Petter Solberg (nor), just to name a few.
I followed rally since my younger days in Kenya. There are some of the restored group B cars on sale and they go for around a million. Audi Quattro S1E5, lancia Rallye 037, Peugeot 205turbo, Ford rs2000. Story of porsche 959 is also related to group B. Some of these cars have set records at pikes peak too.
Firstly, getting blasted with gravel by a Group B rally car was a Major level badge of honour. People deliberately got too close hoping it would happen and the white car at 3:03 and 11:25 is an Opel Manta 400. The chatter/whistle noise is called ‘Turbo Flutter’. This is caused by the turbo hitting maximum boost before it enters the engine and the driver suddenly lifting off the gas pedal. There is no blow off valve fitted so the boost has nowhere to go except backwards, back through the turbo creating that distinct noise. At the time it was believed to maintain boost levels during gear shifting. Remember that these cars were conventional manual H pattern ‘Stick Shift’ transmissions. Finally all original Group B rally cars are considered a ‘HOLY GRAIL’ collectors car so they are often only brought out for ‘Classic Car’ events and races.
Group B cars were seen in European Rallycross events. Regarding your question: the top teams built cars for specific events. They were rebuilt and reused some times. For instance, Michelle Mouton's Pike's Peak winning car was used in previous events and then taken over for the hillclimb.
There’s an event in England called Goodwood Festival Of Speed held every year I think you can see them there, they also do a timed hill climb at the event, it’s very prestigious along with Goodwood revival and I’m sure at one of these two events you have to be invited to enter your car
Finland was known 1000 lakes Rally The noise from the Audi S1 evolution 2 was a 5 cylinder turbo charged engine produces around 500bhp The perfect drift looks likes henri toivonen in the Opel Manta 400 I was lucky enough to see the Group B cars for a few years on the lombard RAC rally of GT Britain 🇬🇧 when I wasa teenager
That flutter is indeed the Audi turbo, yeah. Incredible engineering, and truly one of the most iconic sounds in racing. And, to answer the question of repairs - the teams have an allotted amount of time per stage to do repairs and fix things like suspension, body, roll cage, wheels, engine, etc. Everything takes time, so they have to ration it out, as it were.
Rally Legend is a rally festival in italy where historic and modern cars exactly send it. That being said, theres a replica quattro s1e2 driven by Mal Keough here in australia, incredible but deafening through the forests
There was some treasures that time. Nissan 240RS, MG Metro, Renault 5 Turbo, etc... And those sounds were unbelievable. Some Lancias were rwd and still they compete equally against others.
At 11:23that Opel Manta 400 / car 7 was young Finnish talent Henry Toivonen. Every young boys hero in here, mine too. He was also the last drop to quit Group B.
Yes the group B cars that survived that era and are not displayed in museums are definitely still racing, we have an event in Italy called Rally Legend where historic cars still race, there’s like group B, group A and so on even though not everyone has enough skills or “nuts” to go flat out, but luckily most of them do. There are many more events in europe like Eifel Rally (i hope i wrote that right), you should do a reaction video of the Rally Legend, it’s really really incredibile, especially night stages. Anyway i love your videos, you’re very nice and it’s incredibile to see how amazed you are, like in the TT Isle of man video 😂🤙🏻
I live in Germany near Ingolstadt (home of Audi). Someday I drove with my Motorcycle and I saw one of THIS Audis do a Test Drive on a side street 😍🥵 Engine sounds, Turbo flutter, exhaust roaring. PHENOMENAL 🥹 (A bit of man tears where also there)
Lots of the Group B cars ended up in museums. Some were sold to private owners. Some modified them for hillclimb. Some do historic rallying. Most of them are kept in storage, though.
The flutter is called closed throttle compressor surge. Under high boost when the driver takes foot off of accelerator, the throttle closes and the high pressure air has no place to go but back out the compressor wheel on the turbo. Thats what makes the noise. The flutter is louder if the compressor wheel is open (ie no filter or long tube) this can be fixed by adjusting blow off value. Back then it was just a spring and a harder spring would always keep the boost in the pipe. U wouldnt want a blow off value releasing pressure to soon. Yes look up hillclimbs as they are true unlimited class. U still see these group b cars and plenty of other crazy cars.
I was at a nighttime forest stage, Wales, 1985. Freezing cold, 1am, pitch black, punctuated by each car going by, noise, exhaust, kilowatts of lights, flying gravel. Those few hours have never left me
Went to a night stage in North Yorkshire before, a bad crash happened in the day stage that day and unfortunately a co-driver died so people went home. There were only us and the Marshalls on the entire night stage, pitch black, deep in the forest.
Lights yes but a kW … nope !
@@andyxox4168 Rally headlights are over 100w (in the 80s) Each car would have maybe 6 or 8 for a night stage. Times the 30 or 40 cars that went past…..? Kilowatts
@@HT-io1eg nope, 2 headlights were allowed which had to have max 65W headlights and then a maximum of 6 spot lamps usually with H1 lamps of 100w (which were not road legal!) so that would be 730W total.
@@andyxox4168 Semantics aside, if you're leaning on a tree in the middle of a forest in the dark with only a head torch and the lume on your watch besides the dark indigo of the night sky, a fully lit up rally car flashing through your vision feels like a storm passing by you.
Hannu Mikkola's audi quattro was Restorated here in the west side of Finland not too long ago. My dad was asked to make New seat cowers for the old ones and he obiously agreed. We (basicly all the member in our family) went to the garage where the restorated audi was kept. I was really young back then, but i remember really clearly when the garage door was being lifted and the groub B legend began to slowly show itself. I won't ever forget it. Dad took the seats and we stayed there like an half an hour just looking at the quattro. When we finally got home dad suddenly called them and asked that can he take a small part of the drivers seats main fabric. They agreed an dad took about 3x4 cm peace of the seat fabric and gave it to me. I remember being so SO happy about it. Dad made the seat cowers and gave them to the guys at the garage and the seats are in the quattro right at this very moment in Hannu Mikkola's personal garage and the peace of the old seats cloth is on the wall of my room inside of an audi quattro s1 photoframe. I am so proud to be my dads son. Sorry for the bad english.
nice
Some Group B are still racing in Classic Rally events all over Europe...just this weekend they did so in Portugal to celebrate the 50th anniversary of the WRC
If you check out a channel called Hillclimb Monsters you will see how some of them ended up!
@@bruizey7319 - He's probably aware of the Hillclimb Monsters' channel, since it's a portuguese channel. 😉
Finland and newzealand have the best rally roads in the world in my opinion
These were only demo runs. The 4WD Turbo cars can no longer compete for position.
This 50th anniversary was more like participating, than racing. But there are cars and replicas racing around the world yes
These videos never convey how monstrously loud these things actually are in person. You never forget it.
I agree...i saw these group -b monster few times back in the 80's, in the Thousand Lake rally, and they were so incredibly loud, no matter how far from the start you were, you could always hear them coming...all the way from start..
Rally Finland is known as the "Gravel Grand Prix" because it's so fast. It's also famous for the jumps, cause there's loads of them here.
Audi -driver Hannu Mikkola ones said, that when Quattro S1 was taken to the absolute limit you reach some kind of tunnelvision where the landscape in your right and left just dissappears. While flying thru the multiple jumps on these gravel roads in high speed you are not simply a driver anymore, you are a pilot in an aeroplane flying very, very low indeed. Almost unlimited power combined to the chassis and suspension of that era - it must have been a hell of a ride.
When I play dirt rally Finland is always super fun but if you make a mistake you are royally fucked. Wales is also really damn bumpy for no damn reason. Those two will fucking kill a great season(in game)
Hi, the 'little thing' you mention in the beginning is a Opel Manta :) Walter Röhrl, german Rallye Legend was telling about the Audi Quattro (short wheelbase) that this car was hardly driving one meter strait :D Another qoute from him, beeing asked when a car was fast enough : 'When you enter the garage and you are afraid to lock it on.... Great driver, great qoutes ! Btw., the Quattro had up to a 1000 hp in the 80's !!! This was possible cause there were hardly any technical regulations in Group B. What a time !
2:00 - They all sounded different because of this:
- Audi: 2.1L turbo inline 5
- Peugeot 205 T16: 1.8L turbo inline 4
- Lancia 037: 2.0L supercharged inline 4
- Lancia Delta S4: 1.8L turbo + supercharged inline 4
- Renault 5 Turbo: 1.4L turbo inline 4
- Metro 6R4: 3.0 N/A V6
- Toyota Celica: 2.0L turbo inline 4
- Ford RS200: 1.8L turbo inline 4
- Opel Manta 400: 2.4L N/A inline 4
You can see that some have the same engine configuration but there were other differences that explain the different sounds of similar engines.
3:03 - The Opel Manta 400 was not that little, it was approximately the size of the Audi or the Toyota Celica (and this answers your 3:40 question). 😉
5:10 - Well, I can (two Rally Portugal "under my belt": 1984 and 1985) but the sounds, the smells and the whole experience is impossible to describe in words. Disclaimer: I still have all my fingers. 😄
The only metro i remember is the 6R4 xd
And the Nissan 240RS: 2.4L N/A Inline 4. I think they only ran a couple of times because they were too late to the party.
@@stevegraham3817 - My objective wasn't to make an extensive list of Group B engines, just the ones shown in the video and a few other that might pop up in other videos Ian watches in the future.
@@stevegraham3817 that was a 2.0l turbo inline 4 the engine was a Nissan Fj20
Or it could have been a NA 2340cc and later 2391cc FJ24 built into the BS110 platform.
2L engines, turbo and non turbo, were released in the standard production car models. DR30 Skylines, Gazelles, S30 Sylvia, and possibly others. FJ24 was only in Group B and sold as engines only, some in semi factory arrangements. Check out George Fury's Australian Group G (Oz equivalent of Group B) Datsun 120Y. I think there was also a Stanza, 1600/510 and Bluebird that may have had them as well.

A shame that the Metro 6R4 wasn't there, such an awesome tiny car with a fantastic sounding big V6.
Last car being the Delta S4, you can hear the crazy turbo/supercharger combo.
And gotta throw some love to the Peugeot - most successful group B
Finnish rally is the best rally of the world, and up until the early 2000's Finnish drivers basically dominated the sport. And it was the Group B where Finns shined the most, by winning the titles almost every year:
1983 Hannu Mikkola (Audi Quattro)
1985 Timo Salonen (Peugeot 205)
1986 Juha Kankkunen (Peugeot 205)
Other honorable Finnish drivers from that era to mention would be Markku Alen, who drove Lancia S2 (rear wheel drive) and S4 (four wheel drive), and was holding the championship title for 10 days in 1986, until it was taken away from due the Peugeot's protest. His teammate Henri Toivonen was considered to be the all time fastest driver, and he was dominating the early season of 1986, until he crashed is S4 in Corsica and lost his life. That crash was initially the end of Group B -era.
Probobaly the greatest rally driver Walter Rohrl would disagree on the "greatest rally" as he said I don't like that rally because if I want to fly I would be a pilot not a rally driver. Funny part: he is a pilot as well.
@@altergreenhorn i dont think loeb would be too happy about the greatest driver statement. i live Walter though.
@@lochiecrosbie If so, then you should know that walter did not want to collect championships
@@altergreenhorn Röhrl might have been the most arrogant rally driver of his era, stating that he himself would be the best of all, but honestly speaking the greatest driver ever lived is undeniably Sebastien Loeb with 80 rally wins and 9 consecutive World Championship -titles.
Anyway, there has been public polls about the best rally of the world, and Finland has won it more often than any other rally. It has more speed, jumps and challenge than any other rally. But of course this is just a matter of opinion. I personally love to see cars going 180 to 200 km/h and flying (literally) to the corners, instead of watching how drivers try to avoid flat tires while doing 60 km/h in some ox road.
@@Ilmarintarina Röhl is the greatest allround driver and can do things what sebastian leob or Sébastien Ogier( 2 of the truely best Rallydriver of all Time) can´t do. Search for MOTORSPORT : WALTER'S COURAGE l A NIGHT TO REMEMBER IN ARGANIL , imagine 4min 59sec faster as the secound fastest in the night and with fog on one stage
I know I'm late to the party, but at 11:55 those two are the Opel 400 again, and the Lancia 037. If memory serves, they were two of the last cars in Gp.B with RWD instead of 4WD. And yeah, they were both *perfect*. I'm a Road Racing Boy, but I'm from the Southern US and still go watch dirt oval from time to time. :D
I attended a few Group B events in the UK in the early to mid eighties. You used to hear gunfire like sounds coming through the trees minutes before the Quattros turned up. I was working for Audi at the time so I was quite invested and used to feel a fair bit of pride. My old boss used to do classic rallies and he let me drive his ex Hannu Mikkola Porsche rally car once - fun times.
Wow,amazing story..but i kinda dislike audi for that pr stunt they did in Germany when Misha Charoudin helped the people that were hit by the flooding in 2021 with that audi rs6..
I assume that Audi in UK is far grate managed !
Growing up in the '80s and through the '90s (10-20 years-old), and being into cars and racing from an early age, I still, to this day, get so energized when I see this stuff again. The Audi did it for me. 5-6 years-old watching them things, and then later I went to Lincoln Tech for Auto Tech, then off to UTI VW/Audi specialty training. Problem is that racing and Rally is what I really wanted, not working on cars. Now I'm 42 and thinking of doing some rally training, mostly to pursue for mere pleasure. I sometimes wonder if I am too old though. ???
@@RobHTechcan never be too old to pursue a dream
The 1,000 lakes Rally, also known as Rally Finland, has been running for 70 years. It was first held in September 1951. The Ouninpohja stage, where some of this video was likey recorded, is renowned for it's high speed corners and jumps. In 2003, Markko Martin set the record for the longest jump at 57 metres, while travelling at 170km/h.
Just to help you out with a few questions you had:
- many group B rally cars still remain in the possesion of museums, their manufacturers, or private owners. Some are raced to this day at historic rally events, most notably at the Rallylegend held in San Marino every october. That event is a huge video recommendation!
- about maintenance and repair. A year in the world rally championship consists of 12 rallys usually, so one per month. There are some powerful rally cars, but an engine should last at least half a season, or even an entire season, because they are built to last. Most rally cars are tuned up street cars, and there are strict power restrictions, so they would never be so powerful as to fall apart or need a new engine on the regular
- servicing the cars druing a rally is strictly regulated. Usually twice a day, every 5-6 stages or so cars can go to the service park, where they have a time limit, usually 60 minutes or so to be serviced and repaired. If the team can't do it in the time given, they are heavilly penalized, or can be even disqualified. There are also refueling points along the way, but doing anything to a car is prohibited between stages, and only the driver and codriver can do repairs, if they have a problem on a stage. There are very good examples in "WRC Craziest Moments" for this
"there are strict power restrictions"
This is group B we're talking about here though. There were displacement restrictions, but no restriction on boost.
yeah the group B engines would literally melt after prolonged running infact I think it was the FordRS200 that would only last 12 minutes.
Basically formula 1 on dirt new engines every weekend
Indeed, Group B was a way higher level of tuning, and components didn't last that long, I just wanted to give a more general approach as well, he asked about this, if I'm correct. Let's not forget though, that rallies consisted of 40-60 stages sometimes, so along with all the power, the cars had to be reliable enough to complete a day at least.
Yeah. Sometimes they changed engines after every stage, most parts of engine surely. And also group b have nothing to do with street cars. they were mostly mid-engine cars compared to normal street car counter parts that had front mounted engine. They were basically just fiberglass bodykit on tubechassis.
@@Viperguy88 "usually 60 mins or so". Is that long enough to scrape the co-drivers poo off the roof? Thanks for replying with all that great information, much appreciated! 🏁🚗
That car at 11:30 is a Opel Manta 400 RWD Group B
As a Kiwi in my late 50's, I got to watch the Group B monsters in action.
Unforgettable sound of the Audi's, coming through a freezing cold pine forest stage.
Here I am in 2022, late last year, I bought a NZ new 1990 Audi 90 Coupe ( grandchild to these beasts), non turbo, all original factory manual, service record, original mags, tool kit.
The closest I will ever get to my memories, and an end to a 10 years + search for piece of Rally history.
From one Coupe owner to another, though this one is in Scotland, drive it in good health and savour that 5 pot sound!
Also a kiwi, yea mate what a era of driving class and raw power. Enjoy you’re Audi 90 bro 😎
I still remember watching the Audi's pass through the gravel roads in Hawke's Bay - Michelle Mouton was spectacular
That’s awesome Garth! You should drive it out to the stages here this year?!
Big love on the find, brother! Congrats!!
There are found in an events on hillclimb you may find them or historic event
9:00 The components were designed to last the whole season. The cars were meant to be based of their road-going counterparts (which obviously had to be lifetime reliable). But due to the occasional “off” or crash, powertrain and drivetrain tear-downs might become necessary, situationally.
They also has to make 400 road-going cars before they could compete if I recall correctly.
@@EforEki .. Except for the Lancia 037 where they made 200, showed the FIA 200 in the morning, then had a good lunch on the way to show them ‘another’ 200 at a different location.
And no, the cars didn’t last a season, they were fully rebuilt after every event, sometimes during an event!
@@andyxox4168 Yeah great story that 😆
Ah yes, you are correct sir! 👍🏻
@@andyxox4168 that is such a funny story, I forgot about that
that whistle on the audi i do believe its when the turbo disengages and the supercharge kicks back in at the low rmp and take a huge breath of fresh air
bs
Audi didn’t have a supercharger.
the audi only had a turbo i think it was because they did not have a dump valve so when letting of the throttle you hear the surge of the turbo pusching against a closed throttle body
As the great Walter Röhrl ones said..."while acceleration, the tears of emotion must drain off horizontal to your ears"...."if you can see the tree you crashing in, your car is understeering. If you only hear it, your car is overstreering"
Röhrl was a coward. Never raced in Finland because as he said "if I wanted to fly I would've became a pilot"
@@psynque No he was smart. Therefore he is still alive. Rally was much more dangerous back in the days. By the way, our opinion regarding Walters skills is absolute inconsequential.

Answering to 7:37 question, in San Marino (close to Italy) there is an event called “Rally Legend” on which a lot of historical and modern rally cars compete, sometimes driven by the rally drivers from that era. It is just a spectacular show and every year you can find some original group b cars driven sometimes at 60-70% of their power which is a lot considering that those are incredibly expensive right now
01:35 That noise of the Audi comes from the Watergate - The wastegate is a valve that controls the flow of exhaust gases to the turbine wheel in a turbocharged engine system.
03:02 This little thing is an Opel Manta 400 Group B
03:39 yes its a Toyota Celica TCT
correct... those are the
beautiful noises that an internal wastegate make. my datsun used to make similar noises but a little deeper note, really makes you want to spool that turbo up just to hear the sounds lol.
The Audi noise is flow reversing through the compressor stage (transient surge). Everyone calls it wastegate noise, the noise of a wastegate is just excess air flow from the turbine/exhaust and just sounds like a jet engine roaring, very different noise. 🙂
That Audi was evil as hell
Thought the little thing was an RS200….I was close😂😂😂😂
Was more sophisticated that a dump valve, they had a basic anti lag system that kept the turbo spinning fully.
In Spain when it's rally season you can see them running after the actual rally cars, not as serious as back in the day of course and most of the time they just do the track slowly, but some of the drivers like to show the cars and give a bit of show, either going fast or doing some donuts. It's a nice experience overall, and it's totally free :D
Had the pleasure of seeing the Audi S1 up close at the Australian stage of the WRC here in Coffs Harbour NSW a few years ago. And yes, in person the sound is glorious. That particular car races under the Historic category.
wow, so lucky man..when will be another race in Australia..i really want to see a rally race there..here in Europe is beautiful..but in other continent specific Australia with his cool landascape i think it's so amazing:) going flat out

That chirp that you're hearing off the Audi is an early jab at an anti-lag or recirculating turbo system. Instead of dumping the extra air pressure just into atmosphere when the throttle is lifted like with a BOV, this system instead purged the air into the hot side of the turbo system in order to attempt to alleviate the time spent building back into boost. This not only allowed for a snappy turbo system that mostly did away with the lag created by early large single turbo systems, but allowed Audi to use a smaller displacement engine which revved much more freely and fit class requirements.
no it isn't its compressor stall as they didn't bother to use dump valves to make the turbo bearings last long it just needed to last the stages and get replaced.
Most of the remaining group B all entered European rally cross where they all gained even more power. They reached their maximum potential. Martin Shanker was Mr Rally Cross. Get into mid to late 80s rally cross. The value today of all those cars on the starting grid is mind blowing
Martin Schanche.
6R4, RS200 etc.
2:56 that's an Opel Manta 400. As an American, you might have heard of the Opel GT. The Manta was a coupé derived from the Opel Ascona B, a family sedan based on the H-platform from GM. In the US, on the same platform, in the 70s you got the Chevy Vega&Monza, the Pontiac Astre&Sunbird as well as Buick Skyhawk and Oldsmobile Starfire.
Yes, Flamebeard, Ascona / Manta 400 were highly modified. The engine was developed with Cosworth and car with Irmscher. At the time I had a Manta 2L but wanted a 400, budget & wife blocked that.
@@russcattell955i awesome! Ive got a 2L. and a 200+ hp 16V in the works
@@boerharms2209 Excellent, I had a 2.0 SR Berlinetta coupe. When the 2.0 GT/E came out it was not enough of an upgrade to justify a big cash outlay. When the Astra 2.0 GT/E 8V was better and the 16V (red top) is the motor Manta deserved. I sold mine and bought a Chevette HSR.
@@russcattell955i ahh cool! ive got a 2.0 8V CIH Manta B1 (with chrome bumpers) and dual weber setup, and a B2 that will be receiving the 16V engine once the car is done bodywork wise.
@@boerharms2209 Nice, I imagine the CIH would be tasty with dual DCOE's. In it's day, Manta had a great chassis. I recall having fun with a mate in his Sierra XR4, he was faster on the straights but could not keep up on the twisties, I had 205 tyres & Monroe fast road dampers.
Hard to beat the raw wail of a turbo 5 cylinder engine as in the Audi.
Volvo 850 BTCC car also had a 5 cylinder and sounded like the bowels of hell.
On a side note, you look amazingly like Valteri Bottas. Keep it up.
I agree the unique sound of the audi quatro 5 cylinder engine makes them such a memorable experience.
Had the pleasure of a ride in an escort rs200 rally spec. 700bhp, but was detuned to about 350bhp due to race regulations. It was mental. I'll never forget that drive!
700 bhp in Gp B rally trim … NO!
@@andyxox4168 it was an evo2 so yeah that powerful max out, but as I said detuned for race regulations and I guess, reliability ! The race regs in the UK rallies were a lot stricter in 2012 than they were in the late 1980's
wasn't an Escort. just RS200
I've seen videos of hill climbs just few years ago where some group B cars participated.
My favorite engine noise of all cars that existed or exists is the sound of the Audi Sport Quattro S1.
In 1980s I had a leading rally driver from Finland beside me on a connecting flight from Sydney to Melbourne, sorry do not right now recall the name.
He spoke with me in moderate English, but was more fluent in German so we continued in that. He was about to take part in a series of rallies in the Victorian mountain forests. On noticing we were flying over parts of the area He was about to be rallying in I started describing the places, mountains, vallleys as we passed over. He was so fascinated to see the country from high up. He thanked me profusely for the opportunity to see his rally destinations that way. He offered to have me visit his rally base and view so rally live. I sadly was just returning from Europe to get into some fuel injection test trip work, so was unable to have time to take up the offer. He remained very thankful. We parted in the airport baggage claim area.
(Name might have been Rinkonnen or similar, but I may also be mixing up with other racing names)
Vatanen? Lampinen? Aaltonen? Kankkunen? Toivonen?
@@oldlud8971 I think you got it Kankkunen
i saw these beasts live in Finland back then...recent cars are loud as well but these you could hear
from miles away...just the sound gave me goosebumps...and when they passed by..you kinda had to turn your back to them because of all the dirt and sometimes big stones flying towards you..but still..great fun
Men among boys? They always said that about group b but then there was our homie Michele. Michele Mouton has an Audi Quarto trim named after her from her time in group B. She has a win at le mans as well, in the two liter class. She also hit up pikes peak before Rohl did.
Grup B had amazing cars
Lancia, Peugeots 4x4, bi-turbo, Audi 4x4, you name them.
The raw adventure for a Fan was to be there, in the "first tow", exposing yourself to the flying comets.
Rally Pilots were and are the cream of the top!
Narrow, snowy or dirt roads, often flying through the air, left-and -right curbs and turns, alive and moving walls of Fans on both side of the roads.
And the co-pilot or navigator instructing the Pilot ;
Left turn hook, 45 degrees, followed within 12 meters by a 65 degrees right turn, immediately followed by a 4 meters jump... ",
Nerves of steel, reacting like a falcon r a tiger....
Races like a 500 Miles, in a closed circuit, featuring only 4 identical curbs to the left are kind of boring.
Give me a Great European Rally, or Pikes Peak in Colorado -- there it's possible to admire skills, guts and fabulous cars and drivers..
Thank you for another fantastic Video
4:35 : For us, it's Group B rally madness. For a Fin, it's Monday morning and they're late for work...
And yes, there's a real disparity in where really talented multi-surface drivers hail from. 7 out of 10, it's a scandinavian country.
No, Nordic.
IWRocker, you're doing a great job!
To answer a question you asked within the the video, "the angry little car" you mentioned was an Opel Manta 400. Opel is GM in Europe (Vauxhall in GB), and the Manta was a total RWD beast producing 270 HP with its atmospheric engine - no turbo boost!
The one you saw in video was propably driven by Ari Vatanen, or the the late Henri Toivonen, judged by its livery.
Though the Manta was cannibalized by the 4WD monsters in the WRC, it was hugely successful in many national championships, including the glorius British Open Championship which was regarded as the second best rally challenge in the world, back in the day. The Manta 400 has produced many national legends who have also shown WRC success, while the Group A version Manta 200 has been a career making car for many rally heroes in the making.
Manta was favoured for its simplicity and power by the drivers, while spectators where awed by its spectacular sideways looks.

All the best
Great reaction mate, so good to see you enjoying this! Sorry, I can't answer any of your questions but a couple of things you said in the video made me think you might find it interesting to check out Michèle Mouton. She, and co-driver Fabrizia Pons, were women among the 'men among boys' when they placed second in the 1982 World Championship (in a Group B Audi Quattro). Mouton also performed some of my favourite Group B 'perfect drifts' caught on film when she set the outright record at the 1985 Pikes Peak Hillclimb.
The car you admired at 11:56 is an Opel Manta, two wheel drive and naturally aspirated. A wonderful drivers car. The next car was also two wheel drive Lancia with a supercharger. Both Opel and Lancia have won World Championships with two wheel drive.
Many people think four wheel drive is what makes these cars fast but it is just one factor. Turbocharging added huge HP and then the 4x4 were able to exploit that extra traction. On pavement two wheel drive still works very well.
Thanks dude! I saw them many times live, actually every Jyväskylä Rally. My father was a petrol head so it was our tradition. Finland has more rally world championships than any other country. Actually last weekend Kalle Rovanperä won the Portugal WRC-rally. At least the Finnish group-B drivers, which were many, have these cars in their personal collections. And some of them are still "racing" in different classic-car races. Or hill climimg etc.
If you wanna see something funny, watch Ken Block testing Audi-B cars in a secret Audi facility in Germany. It was his childhood dream.
That flutter noise in the Audi was the wastegate opening and dumping exhaust for the turbocharger that car was making 500-600 bhp. The Lanica Delta car was making 500 hp with a compound system with a supercharger feeding a turbocharger... from a 1.8L engine in the mid-80's!!! Rally cars might be faster now but they aren't driving them on the ragged edge.
A recommendation: try watching European hill climb highlights; crazy fast cars on tight public roads. A favourite of mine is the Prospeed Audi S1 (around 800 HP) - fantastic sound. Loving your racing reactions!
Min 3.00..."that little thing" is a Opel Manta B400! In 1982 they were fighting for the world championship! A 2,4 liter with about 280HP and less than 1 ton. RWD
Also fun fact, that rwd car that did the perfect drift may look familiar ( the opel manta 400 ). Its a similar bodyshell to the 80s style Holden commodore.
So true ich have a opel ascona b 400 Phase 3 have the same engiene
Gotta love a 400 😘
@@markmclean4897 yes i have luck and have buy for 10 years for a low price now is the prime 4 x higher
I remember attending the circuit of Ireland rally back in the 80`s and to this day I will never forget the sound of those Audi Quatros going past with flames gushing out every gear they took. The Metro 6R4`s were something else too.
4:25 Finland's rally pedigree is undeniable. They're known as the Flying Finns for a reason.
Hannes Kolehmainen, Ville Ritola and Paavo Nurmi were the Flying Finns. No-one since has ever deserved the title.
@@Derry_Aire in track yes, in road no. the 1st ''flying finn'' in the road are: Timo Mäkinen, Rauno Aaltonen and Simo Lampinen .
check timo mäkinen in mini cooper S and bonnet/hood. when driving hood up and despiced that he finished just 3rd in that track. and won whole rally
I love Finland, but in those days Corsica was way more interesting and more fun to watch imho. Nowadays, yes, I think Finland is prolly my favorite.
@@Derry_Aire Kalle Rovanperä has surely earned that title now
1:50 when you take your foot off the gas, the still-spinning turbo presses the air against the air vane (translated by deepl), which gives way at a certain pressure, thus opens briefly and lets the air out, producing this repetitive sound by rapidly opening and closing and opening and closing and so on. this ruptures the turbo-bearings in time, so a waste-gate was introduced, which short-circuits the air-flow at negative pressures, making the typical hissing sound you can hear nowadays.
My family and I live in Turin, where back in the 70s and 80s the Lancia Squadra Corse was based. My dad went to school in the Lancia technical institute, which was in the same building where squadra corse used to build their car. Every time we talk about these times, he tells me how glorious the engine from the Lancia Stratos and 037 used to sound on engine test bench, where they were pushed to the limiter for hours, until the breaking point. Also, coming out of school, seeing all the cars being lined up outside the building was just incredible, you could smell the racing atmosphere around that place…
That Lancia Delta S4 you had as the last clip was actually a 1.8ltr Turbo charged and Supercharged.
Lancia did that so the Supercharger would eliminate any Turbo lag that was associated with these beasts.
Great video mate.
If you like to know more about the insanity of the rally sports, you might like to take a look at 2 events:
The pikes peak race in 1987 where Walter Röhrl came to Colorado with his Audi quattro S1 and
The famous night of Arganil in Portugal 1980 .where Walter won a night special stage over 42 km (26 miles) 4:40 faster than the second place.
even michele mouton one of the group b rally drivers drove a audi on the pikes peak hill beating bobby unser record.
@@harshithsadhana7475 I was not aware that Madame Mouton was there (at Pikes Peak) already 2 years earlier to win the race in 1985.
(There is always something new to learn)
Even today, at least in France from what I can tell, there is a category for older cars called VHC, Véhicule Historique de Compétition (historic competition vehicules) but not often you gonna see Audi S1 or Peugeot 205T16 considering they cost probably over a half million 😅
But yeah you can still see older cars in these events
Rallying makes F1 look boring. I was lucky enough to be a Press photographer for the British Internationals (Scottish, Wesh, Mintex/National Breakdown and RAC rallies) covering the late seventies to late eighties. I saw the change from Ford Escort dominance to Quattros and then Group B. Fabulous days.
3:00 …was a Opel Manta
When Group B ended, you could find these cars being used for Rallycross as well as hill climbs. We still see them racing today in historic rally events and classes.
The quattro s2 e1, manta 400, delta s4 and 205 t16 evo2 are probably my favourite ever cars.. and not just rally cars.. cars in general... absolute masterpieces of engineering!!! The flutter on the big winged audi is actually compressor stall from the turbo due to running hardly any wastegate at 650+bhp so the turbo actually stalls (many people call it the blow off valve, but they didn't run an external blow off valve..the blow off valve recirculated back into exhaust system) its pretty much the back pressure of the air pressure generated causing the turbo compressor wheel to stall
I saw a old group b driver takes the quattro out a couple of years ago and they put one camera on the pedal box and one camera on the gear Stick it was insane to keep up with what I was watching
A lot went into collections, but also something called Rally Cross a circuit event when they would drive a short circuit on loose surface & tarmac. They ramped the power up even more the Lancia delta, with over 700hp. Closely followed by the 6R4
The angry car was an Opel Manta. And the drift into corners is known as The Scandinavian Flick. They are taught to do it during driving lessons to achieve a driving licence because of constantly adverse road conditions in winter.
To answer your question regarding the stututu noise from the quattro. It's actually just the noise of compressor surge. Typically it'll happen when a turbocharged car either produces too much boost for a BOV to keep up with when letting off the throttle or when a turbocharged car lacks a BOV entirely. Where in letting off the throttle closes the pathway for the boost to enter the motor and is sent back through the intercooler and intake piping and back through the turbo in reverse which still has the turbine spinning clockwise. Making the iconic stututu fluttering noise.
The hissing of the Audi comes from the intake of its turbocharger. As the throttle gets closed at high revs, the turbo still is spinning fast under its impetus but the flow through the centrifugal compressor is reduced drastically. Like when the wing of a plane stalls at high angles of attack, the airflow on the compressor wheel's blades gets separated. As the turbocharger spins down the pitch of the hiss drops audibly.
To answer your question about the squeaking and chirping noises ...You have to remember that during this era, there really wasn't any computer stuff on cars yet so all the "go fast" modifications were mechanical. A few teams had sequential shifters by this point, but no paddles as it was a huge lever in the center of the car. The noises are the turbo waste gates...the diverter valves have been removed as it helped with boost pressure re-build after lifting off the throttle. Lag was a HUGE issue during this time frame...So to go back in history: turbo charging came about during WW2 on fighter planes...some were supercharged AND turbo charged. Turbos were first adopted to Diesel engines and I believe it was Porsche who first brought the technology to gasoline race cars with their 12 cylinder Can Am 917 racers in 1972. These were not intercooled at that time but still made a mockery of everything else in the field...from 72 through 74. The "gas crisis" of 1975 brought an end to auto racing in the US for a year and a half. Glad you're digging this...!
7:20 Nowadays, in rally events, there are presentations of classic cars., included Group B cars. Spectators will be able to see the vintage cars up close as they race. European public love Group B cars.
Events used to be up to a week Long and about 3500 miles with about half as stages. Army's of mechanics and service vans had to set up service parks in wayside stops all over the place. Motors generally where tuned up to the max that is possible to get thru the event.
Here in Europe they still race in special events, exhibitions and historic rallies. Lots of people are even doing crazy restomods of these monsters. The most noticeable being the Kimera EVO37 based off Lancia 037
Some group B stills racing on a regular races. In regular races don't matter who goes faster, but who do the most regular time in the laps. There are some special Rallyes for the classics cars like group b.
The chirping noise is off throttle surge. Caused by the throttle closing, which in turn reduces the airflow of the compressor (compressor map point moves left) so that the surge line is exceeded on the compressor map for that combination of compressor speed and pressure ratio. The compressor cannot supply the air flow for this pressure ratio, so the compressor speed and pressure ratio reduce until the compressor can again sustain the pressure ratio and airflow. The compressor speed then increases, increasing the pressure ratio to the point of surge. This happens many times a second giving the chirp.
Quite a lot of these former Group B cars found a new lease of life in rally cross, which is equally crazy and fun.
IWrocker, if I had enough money, I'd turn up at your door and take you to Finland to watch WRC, you're one of us now, by that I mean rally is your favourite motorsport. Love your reactions, the fact you know when the audi is coming shows you're a true fan.
The 'Angry little thing' was an Opel Manta 400. That was also the 'perfect drift' you mentioned :)
The Swedish driver "Stig Blomqvist" still drive his Group B Audi in special events, I think he was drivning in ROC (Race Of Champions) last year
Rallies take place over Friday, Saturday, and Sunday. The cars have to drive on public roads to get from one stage to the other. Some stages, have a full mechanics team to repair and prepare for the next stage. Some stages don’t have any crews, and it’s up to the drivers to do the repairs themselves.
Audi rally cars were called as snowplowers cause of the front spoiler.
goodwood festival of speed in UK, hillclimb events, historic rallies- these are events you can visit to see the cars. even collectors and some factory teams do make some appearance in these events.
Lot of cars were used for rallycross and some are in museum or became collector pieces. There are also enthusiasts who are making replicas and so on and rally those as privateers. There is so much rallyes going on nowadays and sometimes if You are lucky enough You can see f.e. GrB Audi storming the stage as safety car. Just insane!
To answer your question - they often appear at the Goodwood festival of speed and in historical race events, most of the cars though spend most of their lives in private collections and museums,
David Llewelyn a quiet welsh guy drove a 6r4 metro like a madman and when he was interviewed about it he would say he’s going so fast and looking so far ahead he had to judge where the road would be by looking at the trees not the road, insane power 😎✊
The car that blew your eardrums is a Lancia 037.
A rally is mostly a few days and after each day they are allowed service and broken things get replaced then. But it's all time restricted, so they only have as limited amount of time to do it. I also believe that it is restricted/limited at what you can repair/change with each service, like engine and transmission. Some mechanical from rally's crews (and other motorsports I gather) can change a transmission in about 7 min.
3:00 Opel Manta B 400. I used to have one. Well, not the 400 variant. Mine had a 2-litre four cylinder with twin dual 40mm Dellorto carbs, different camshaft and a tube header. It wasn't tuned for max hp, it only made about 140hp on dyno (40hp over stock) but it was a nice, streetable engine. The car only weighed ~2250lbs so it went fairly well.
4:35 The Finnish rally has traditionally been known as the Grand Prix of gravel roads. It's the fastest rally in the WRC calendar.
The chirping sound from the audis are chockwaves from when the turbo goes from full charge (full gas) to let go of the gass (less/no charge). It only happens whith a certan ratio between turbo house and plenum chaimber. You can hear it on some of the saabs 16 valve too. Fun fact: scandinavia has produced the most number of highly ranked rallydrivers in the world, in relation to size of the countries. Finland has the most, fex: Tommi Mäkinen, Hannu Mikkola, Ari Vatanen, Marcus Grönholm, Markku Alen to name a few. Other worldclass drivers are Stig Blomqvist (swe), Björn Waldegård (swe), Eric Carlsson (swe), Andreas Mikkelsen (nor), (Greta Molander (nor), Petter Solberg (nor), just to name a few.
I followed rally since my younger days in Kenya. There are some of the restored group B cars on sale and they go for around a million. Audi Quattro S1E5, lancia Rallye 037, Peugeot 205turbo, Ford rs2000. Story of porsche 959 is also related to group B. Some of these cars have set records at pikes peak too.
Firstly, getting blasted with gravel by a Group B rally car was a Major level badge of honour. People deliberately got too close hoping it would happen and the white car at 3:03 and 11:25 is an Opel Manta 400.
The chatter/whistle noise is called ‘Turbo Flutter’. This is caused by the turbo hitting maximum boost before it enters the engine and the driver suddenly lifting off the gas pedal. There is no blow off valve fitted so the boost has nowhere to go except backwards, back through the turbo creating that distinct noise. At the time it was believed to maintain boost levels during gear shifting. Remember that these cars were conventional manual H pattern ‘Stick Shift’ transmissions. Finally all original Group B rally cars are considered a ‘HOLY GRAIL’ collectors car so they are often only brought out for ‘Classic Car’ events and races.
Group B cars were seen in European Rallycross events. Regarding your question: the top teams built cars for specific events. They were rebuilt and reused some times. For instance, Michelle Mouton's Pike's Peak winning car was used in previous events and then taken over for the hillclimb.
Ken Block is a big fan of the Audi Quattro S1 and he has one in his collection
There’s an event in England called Goodwood Festival Of Speed held every year I think you can see them there, they also do a timed hill climb at the event, it’s very prestigious along with Goodwood revival and I’m sure at one of these two events you have to be invited to enter your car
Finland was known 1000 lakes Rally
The noise from the Audi S1 evolution 2 was a 5 cylinder turbo charged engine produces around 500bhp
The perfect drift looks likes henri toivonen in the Opel Manta 400
I was lucky enough to see the Group B cars for a few years on the lombard RAC rally of GT Britain 🇬🇧 when I wasa teenager
That flutter is indeed the Audi turbo, yeah. Incredible engineering, and truly one of the most iconic sounds in racing. And, to answer the question of repairs - the teams have an allotted amount of time per stage to do repairs and fix things like suspension, body, roll cage, wheels, engine, etc. Everything takes time, so they have to ration it out, as it were.
The chirping sound is the dump valve opening when they go off the throttle.
Rally Legend is a rally festival in italy where historic and modern cars exactly send it.
That being said, theres a replica quattro s1e2 driven by Mal Keough here in australia, incredible but deafening through the forests
There was some treasures that time. Nissan 240RS, MG Metro, Renault 5 Turbo, etc... And those sounds were unbelievable. Some Lancias were rwd and still they compete equally against others.
At 11:23that Opel Manta 400 / car 7 was young Finnish talent Henry Toivonen. Every young boys hero in here, mine too.
He was also the last drop to quit Group B.
Yes the group B cars that survived that era and are not displayed in museums are definitely still racing, we have an event in Italy called Rally Legend where historic cars still race, there’s like group B, group A and so on even though not everyone has enough skills or “nuts” to go flat out, but luckily most of them do. There are many more events in europe like Eifel Rally (i hope i wrote that right), you should do a reaction video of the Rally Legend, it’s really really incredibile, especially night stages. Anyway i love your videos, you’re very nice and it’s incredibile to see how amazed you are, like in the TT Isle of man video 😂🤙🏻
In 1986 Carlos Seinz (senior) drove his group B Lancia round Estoril and would have qualified 6 for that year's F1 Grand Prix.
Im going to finland all the way from seattle in August for the rally this year. Its a bucket list item for sure. Cant wait!
I live in Germany near Ingolstadt (home of Audi). Someday I drove with my Motorcycle and I saw one of THIS Audis do a Test Drive on a side street 😍🥵 Engine sounds, Turbo flutter, exhaust roaring. PHENOMENAL 🥹 (A bit of man tears where also there)
We have one of the Group B rally´s every year, in my hometown here in Finland. It is always so fun, we go to a good spot and watch when cars go by.
the car that took the corner so elegantly was an Opel manta 400 grubbe B. Rear-wheel drive.
Lots of the Group B cars ended up in museums. Some were sold to private owners. Some modified them for hillclimb. Some do historic rallying. Most of them are kept in storage, though.
The flutter is called closed throttle compressor surge. Under high boost when the driver takes foot off of accelerator, the throttle closes and the high pressure air has no place to go but back out the compressor wheel on the turbo. Thats what makes the noise. The flutter is louder if the compressor wheel is open (ie no filter or long tube) this can be fixed by adjusting blow off value. Back then it was just a spring and a harder spring would always keep the boost in the pipe. U wouldnt want a blow off value releasing pressure to soon.
Yes look up hillclimbs as they are true unlimited class. U still see these group b cars and plenty of other crazy cars.
