I was at the factory in 98 and 99 for training.
The assembly line tour in August of 99 was very solemn.....all the 2 stroke production was consolidated to 1 line.
I was a young buck in my mid 20s, but I still cried.
I cried for the memories of the older guys who worked on them daily.
I cried for the younger generation who wouldnt get to experience what little ive experienced with them.
Every time I hear one, I hear history and something awesome that helped build this country.
I rebuild the 6g92ta engines for the USCG daily, come see me always looking for someone to work on these.
It’s some cast iron and aluminum not your ex wife calm down a little
I put a 4-53n in a 1972 Ford F-250 4x4 pick up. It was very cool truck.
I was trained to rebuild, repair and operate the Detroit Diesel 6-71 marine units for use in Coast Guard patrol boats in particular the steel hulled 40 foot boats which used two. In the engine's early days the marine units were branded as "Grey Marine Diesel" In the inline 6-71 there was a two exhaust valve engine that was normally aspirated and a 4 exhaust valve engine that was turbo-charged. For those that don't know, the suffex on the engine's designation, 71 or 53 ect. designates the cubic inches per cylinder. The prefix designates the number of cylinders and if the number has a "V" after it, it means that it is a V type block. A 6-71 is an inline six with 71cu. in. multiplied by 6 or 426 cu. in., a 6V-71 is a V6. The only big issue that we had was to have a "runaway" engine. This happens when the air box drains get clogged and the engines lube oil starts entering the intake ports, (two stroke Detroits don't have intake valves, only exhaust valves). It starts using the lube oil as fuel along with the injected diesel fuel. When this happens the RPMs start increasing at an uncontrollable rate. The only way to stop these engines from destroying themselves is to stop the engine's incoming air. The early engines didn't have a cable operated block off plate that was situated at the intake of the blower to stop the incoming air and to stop the engine. The alternative that we had was to use a Co2 fire extinguisher that would be discharged at the intake. This would stop a runaway pretty effectively. As a boat engineer I always made sure that there was a fully charged extinguisher on the boat when I had duty.
General Motors also had a two stroke Diesel that was in sorts a bigger brother to the Detroit series branded "Cleveland Diesel", these were inline units which had separate cylinder heads for each cylinder. My experience with them was inline eights connected to generator sets on WW II era cutters. Thanks for the video, you brought back some memories of a great engine series.
And there was also the EMD 2-stroke diesel, that evolved from the Winton 201 that was used in the famous Burlington Zephyr locomotive. Cleveland diesel started as the Winton Motor Co, and was bought out by GM. Detroit and EMD diesels were developed in the mid-1930's at the GM research labs, bringing about a transportation revolution that resonates to this day. The Detroit 2-stroke was lost due to its inability to meet ever-stricter NOx emissions standards and it couldn't compete with high torque-rise 4-strokes in heavy duty trucks when it came to operating economy. But they always did sound great.
William Charles yes thanks for the extra info and your service in the USCG. My family owned a small mom an pop trucking co. from the late thirties to 1981, when the dreaded teamsters union ran us out of business. So you could say I grew up around trucks, from straight trucks built by GMC, with the big block V6 gas engines at 351-401 cubes, with giant two brl carbs and Six speed trans with two speed rear. To a couple Mack R 500 straight trucks with 210 Scalia Varbis in-line 6 diesels with two shifts, one for low and high, the other a straight 5 speed with reverse. They were all refrigerated with Thermo King units powered by Wisconsin cast iron single cyl gas engines. Then we had a fleet of White 9000 single axle tractors powered with Cummins diesel with 10 speed Roadranger tranny’s. My father had hired a great mechanic full time and paid him very well, that man taught me everything I know about getting my hands very dirty and being able to fix or rebuild anything that has wheels and burns gas or diesel! Matter of fact he was a Master Machinist Chief in the USCG! As far as I know. I’m not sure of the rankings in the USCG, but I know it was high up after 20 years! He also always owned a boat and made a lot of money in the side repairing them! He was a great guy! I’m also a Veteran, 1973-1976 U. S. Army.
William Charles
My last unit in the Coast Guard was the 13th district assist team where we rebuilt 6V53 for district lifeboats. It was great duty, MKCMJoe Gelokaska was the POinC of the unit, located on the Lake Washington Canal in Seattle, Wa. Moon Morrison, MK-1
Thanks for your knowledge and experience on Detroits, I spent many a mile behind the wheel of k series Kenworth and W series, 6v 71 n/a 8v71 n/a 6v 92 tta 871 tta 671 na all great thanks.
@@k.r.v.4219 great thanks.
DD built this country. There’s never going to be another diesel that sounds like they do. Absolute music to my ears.
Which country? There are viewers of different nationalities here.
A Detroit is on of those engines that makes you just not give a shit about what mileage you get because the sound is sooooo good
Actually the 6-71 in my bus gets better mileage than a 4 stroke in other busses 10-12 vs 6-8 mpg
Two stroke diesels often sound like they're screaming when they're really not reving all that much.
They revv a bit higher than other diesels though.
They barely get up to 2.5k, modern 4 stroke Volvo FH can go up to 3.5k. It's because the power stroke and exhaust stroke happen twice as much as on a 4 stroke and thus sounds like its revving twice as fast
@Edwin Orantes My Dad called his 238 a YammerHammer (Yamaha). It turned 2750 rpm which is insane. But he built it to take it. Chromed crank, oversize injectors, a little fine tuning on the pump and there you go. Eat 290's for breakfast and make 318's question their lineage all day and all night.
you all probably dont give a shit but does someone know of a method to log back into an Instagram account?
I somehow forgot my password. I would love any assistance you can give me!
@Travis Max instablaster ;)
One of the great things about the inline 2-stroke Detroits for marine use is the ability to customize the layout of the intake and exhaust. Boats tend to have smallish engine rooms, so the ability to move the blower and exhaust manifold from one side of the engine to the other for clearance issues was very useful. Pretty cool old engines, the design is from WWII and a great many are still running strong!
It's interesting, how 2 stroke diesel sound like it's revving like 5000-6000 RPM but it's running only on 2000-2500....
Matúš Mikula they fire each time the piston goes up.
I'm sure most of those didn't get all the way to 2500. I shift at like 2200 when I'm driving angry.
realistically. they were shifting somewhere around 1500rpm. anything after 1800 is just noise
thats their unique feature
@@REAPER0D makes sense. Peak torque at 1500rpm but peak hp is the governor limit
That’s because unlike 4 strokes they fire in every second cycle. So they sound to be revving twice as fast as they are.
I started working on Detroit Diesels as a young man in the mid seventies and I love them. My favorite is the in-line 6-71. But the largest I worked on was a 12-v-149 used in 100 ton rear dump Euclid off road trucks.
I would love to have a 6-71 in an old B model Mack to play with .
Detroit Diesels Rule!!!
In Australia there is a 6-71 or 6V71 in a B model Mack restored as well. Google search that one. The 8V71 is my favourite.
Use to drive off highway log haul trucks with buzzin dozen V -12s. Ear plugs and ear muffs required. But the sound pulling grade with a full load of Doug Fir. Oh my.
I worked in a large generator room with 6 16 cylinder detroits and 4 Cats about the same size. The sound in that room would blur your vision...it was horrible and awesome at the same time.
David J If I ran a buzzin dozen truck I'd certainly muffle it.
David, I know what you’re saying.. fresh cut timber, fresh exposed dirt, burning diesel fuel... that is indeed a heavenly smell.
Back in the 1960s I travelled a lot by bus. This video had me all nostalgic for the hypnotic mellow purring, the faint whistle and a whiff of diesel.
A buddy had an ancient wooden boat with twin turbo charged 6-110s. Talk about burbling!
The 6-110 platform was a tremendous engine and one of DD's biggest mistakes of discontinuing it's production. They totally misread the upcoming needs of OTR truckers of that era. The 6-110T was a good 15 years ahead of Cummins & Cat. in hp & torque outputs in it's stock, factory ratings... outputs could have been Reliably been doubled (and Were, on the dyno), if needed.
Yea, though I walk through the valley of the shadow of death I will fear no evil, for I ride atop a screaming Detroit Diesel
speedskiff2 a 12v71
early 80s ran one in a 71 KW cabover. 434 hp version. just a pair of 238s!!
LOL.
Best saying ever.
Oooh this fire
Imagine the looks on people's faces if a Minister casually read that passage at the funeral service of a deceased trucker. 😏
Thank you for adding that Australian Kenworth with the 12v71 hauling those antiques!
12v71 was always my favorite. We had a pair of them in a 44' Offshore Raceboat making 1100 hp each with 40 psi boost at 2700 rpm. Quite a sound for sure. Thanks for the video it brought back memories. I worked on all but the 149 series.
I would have loved to see or hear that boat. Wow!!!😊
149s were quite different as the cylinders heads are round and set down in the block. The blowers are also inside the block
Gotta love the 6-71. It's one of the most common and best sounding. We had them in all our trucks. When they'd get side by side on the highway with both engines revved there was a reverb like a "waaa, waaa, waah" that seemed to distort reality. it was awesome.
There were no 2 cycle Detroit diesels that were naturally aspirated they need a positive displacement supercharger to run the turbo charged version still has to have it as well
Luke Nellermoe yea I was wondering about that myself!
It’s a blower not a supercharger as the Detroit was a loop scavenge type two cycle.
They had a Roots blower to blow air in, since it's a 2 stroke with no intake valves. 318 was the nominal hp of the naturally aspirated 8V71. But you can turbo charge them too, just like any other internal combustion engine.
That whistling sound from the blower pushing that intake air through those intake ports was unique, also. I loved it!
And now people besides aging semi truck drivers will know of the glory of the old 2 stroke Detroit. Love these beasts and hope to own one some day
I worked on General Electric gas turbine generator sets all over the world. Many of these had 600 HP Detroit 12-71 twin turbo engines as a STARTER MOTOR. It was a common starting means on MS5001 turbines that were rated 24 Megawatts or over 30,000 HP at 5100 rpm. The 12-71 would start, idle for about 20 seconds, then go wide open governor to spin the turbine up to 20% speed where the combustion system lit off. The Detroit would be screaming the whole time while the turbine accelerated and finally over ran the jaw clutch driven by the diesel. The Detroit would go to idle and cool down for a few minutes then shut off. The whole process took about 5 minutes of wide open diesel power.
Anyone who has seen Maximum Overdrive knows the sound of an 8V71 all too well 😄
8v92
It sounds like an 8-71 to me. Has too much cackle to be a 92 and you don't hear the turbos spoiling. Has got to be a 318
MovinMetal yes lol
8v92tt
MovinMetal the green goblin truck. That screaming Detroit motor was perfect for the movie
This is one of the Finest Music Videos EVER!
👍
We had a 1953 FWD truck with an inline 6-71. What a powerhouse that was. I drove city buses for many years. We had 6V-71, 8V-71 and 6V-92 engines, depending on the year and model of bus.
The 671 was strong. We had one in a 52 Euclid belly dump. Loud and proud. Had an old Clark 5 transmission.
I'm a heavy diesel tech and most of my work is on site. recently had the pleasure of fixing some external oil leaks on a 12V92 spinning a generator. Complete with original Detroit cast radiator. Sounded great in a shipping container with twin exhausts through the roof. My only complaint with these engines was the lack of torque figures. All up and therefore gotta keep them revs up.
I always loved the sound of a properly tuned 2-stroke; I have many fond memories of hearing (usually) a big 12V92 on the engine dynamometer
while being employed at Superior Diesel in Charleston, South Carolina from 2000 to 2013 as a parts guy. Nowadays it's a treat to get a break from a modern engine with EGR & aftertreatment emissions technology to chase parts for a surviving 2-stroke...thanks for the trip down memory lane, although I do wish you would have given a shout out to the venerable 6-71
4:11 The 6V-92 is a real screamer.
De Feschder Its a screamer but it's only Reving to half of what it sounds like.
De Feschder that's the nature of the two stroke beast. Every time the piston goes up the cylinder fires.
Thank you! It's a blast to drive . Check out my videos @ 6v92 white
@Jeff garrett I have the 8 V 92 in 1982 bluebird wanderlodge motorhome
For those who don't know, you can figure out the displacements on these very easily. Take the last two numbers, which is the cubic inches per cylinder. 53ci, 71ci, 92ci, etc, and multiply it by the first one or two numbers. That's the whole displacement. Divide the cubic inches by 61.237 for liter displacement.
Can't get enough of these old Green Leakers. Bonus points that a lot of vintage semi tractors look much more aggressive than the modern trucks do.
That v16 red truck brought a tear to my for how beautiful it sounded
The last of the Silver 8v92TTA DDEC IV we had in trucks in Australia rated 440 -475Hp were stuff dreams were made of
Wonderful love those Detroit diesel engines, the 8v71 ta, 6v92 tta, ever so reliable, I done over a million miles with these power plants in front of me and under me. Just great thanks.
Nothing like the sound of a Detroit. I've worked on and operated everything from the 4-53, 6V-53 up to 12V and 16V-248-A Engines. Including the Slant 6-71 which I have seen set-up with twin-turbos. The Slant was an inline 6-71 layed almost on its side for use in boats. Great Engines most reliable as Stationary or Marine Engines. Something you didn't mention is depending on how the valve train is arranged you could run the inline engines in either direction. This was real useful for marine applications where rotation is critical. The one thing you could always rely on is they all leak oil.
The thing with the 71 series in a truck you can tell how the previous driver was operating the engine when they turn it off when they come in for a truck stop. If it's an 8V71 and they've been lugging it rather reving it both air box drain tubes will have a healthy oil spillage on the ground. I had a mate that drove Detroits in trucks and buses and the ones he used hardly leaked, always dry, trust me I serviced them. The bus fleet had VT903s Cummins as well that only used a bit between changes.
My old log truck had the sweetest 318 Detroit you ever heard purring out of twin stacks
No other diesel engines in the world sound like these. Eargasmic! It's funny, my father is in his 70's and still works on diesels. The young kids are sort of clueless when one of these "old" 2-strokes come in for work; guess who gets to work on them lol. On a side note: A blower was considered naturally aspirated as the 2 stroke Detroit's would NOT run without them.
I’ll go toe to toe with anybody on any Detroit from 51 series to a 149!!!! Rebuild,overhaul, diagnosis, tuneup,rack set, governor adjustments,surge screw,gap screw, governor bump just bring it!!!!! Left handed right handed it don’t matter….
I remember coaches that used the 6/71 Detroit, very distinctive sound and they were quick too!
Yes! Had hoped youd do this video eventually. Great stuff! Detroit Diesels are still being used today by the US military in a wide variety of applications from diesel generators, trucks, mobile lift(cargo) platforms, and are even still used in boats!
This channel is the best for random knowledge. Love how no matter where you are from, you can school a kid who grew up falling asleep to these engines on the school bus.
My middle school bus was a older round bus that was manual and had a Detroit diesel and it was a lady that drove it , used to sit in the front because I loved watching her double clutch and go through gears ⚙️😁
Brockway - now that's a name you dont't hear much. I remember my dad mentioning them.
Mack killed them off probably
My uncle had 2 of them, 1 8v71, 1 big cam Cummins.
Love the sound of the 2-stroke Detroit diesels.
That fire engine at 4:06 oh my god.
It doesn’t even need a siren
That 6v92 fire engine taking off made me shiver a little. I want electric power plants to take over the world, but that was just delightful.
I had a 8v92 pumped got around 5.5 mpgs that was in the 80s I hear a lot of guys with modern cats only getting that
buT tT's CleAnEr😆
8:56 this is how American trucking could look like if there were no oil crisis at all. Imagine this beast averaging 1 MPG hauling 5 heavy trailers across Arizona. One trailer is a fuel tank.
Dutch truck manufacturer FTF (Floor Truck Fabriek) used Detroit Diesel two-strokes in their trucks mainly fabricated for very heavy transport. You can see a logo from them in the window from the office in the 16 cilinder part. Now they only produce trailers, you can see them on the road with "Floor Holland" on the mudflaps.
Again you made a nice video. There are a lot of compilations on youtube, but yours are simply higher quality and it makes them nicer to watch. Keep up the good work!
Love Detroits,, matched with a Brockway the best combo
Nothing will ever replace the noise of a Screamin' Detroit up a 4% grade.
Smoke? ✓
Power? ✓
Amazing noise? ✓✓
id cross out the power lol
Power... lmfao. I've owned 12.7 Detroits with 625hp /2050tq, but none ever sounded as sweet as a 2 stroke
tinnitus - check
Hearing loss - check
Got em both......
@@wharris302 One thing to keep in mind is that the power the screaming jimmys produce come from much smaller motors than their 4-stroke counterparts.
A 6-71N has more power than a Cat 3306 from a 7 litre vs 10.5 litres from the turboed Cat.
Here in the UK I haven't heard the distinctive sound of a two-stroke diesel for many years. I remember the Commer (Dodge) from the 1960s.
The 4-53 has a nice sound to it.
Detroits make a wonderful sound
I bet your mind would change if you drove one on long hauls for 25 years lol.
@Charlie K.... if so, then why are you on this video site in the first place? : )
Real diesel sound! Not like the super quiet diesels they have today!
nvmyevo 4 stroke shit Diesels with Common rail they Sound shit
Quiet only because of the bullshit emissions systems. My old 12.7 Detroit is an old noisy bitch, click clack clatter clatter
@@ManOfAttitudeLP1998 Fun fact: Detroit two strokes are all common rail!
@@holysirsalad Didn't imply that is changing the sound it actually is the 2 stroke but still common rail 4 cylinder diesels have this idk how to call it needling sound
Yes! The Vis showin' some love to my favourite diesel engines! 🖒
Great vid....thanks! 😀
FREAKING LOVE THIS CHANNEL!!! SERIOUSLY, THANKS DUDE, YOU'RE AWESOME
4:07 Wow that sounds good.
My favorite is the buzzin' dozen.
Hell yeah!
All those Detroits hunting and surging makes me sad that no one knows how to properly tune them and adjust the buffer screw.
i thought that was because they were cold, goes to show how much i know about detroits....
That's the buffer adjustment or worn fuel control linkages.
You're correct. At first start up a Detroit surges up and down,but idles entirely different when warm.
surge till there's some heat in the blocks...
Joshua Leach I agree but there's a lot to factor in such as gov. Riser may be worn out or gov gap nor set right. All that has to be properly adjusted and set. Plus the rack has to be set correctly. Then after the engine is warm you can set the buffer. My rule of thumb is turn buffer slowly until rpm slightly increases then back off half a turn the fine tune it from there
i spent over 40 years in broadcasting. For backup power we had a 12-71 Detroit. It screamed for a week keeping the station on the air. We have hurricanes in Florida. Now it did like its fuel.
That 24-V71 in the truck at the end made me laugh. The driver's view of the road is obstructed completely, but it is still a sight to behold!
It's fake. Most the blowers are for show.
Another interesting note to make about Detroit 2-strokes is that you could tune them to get decent fuel economy (92-series engines seemed to best benefit from this) compared to the competition.
6:40
This thing came straight out of Mad Max!
the only difference is it is not rusty :P
And has windscreen.
I grew up working on 6-71s I was looking forward to seeing one.
Spent 2 years around 12v71's. My hearing will never recover
The 71 and 92 series sound awesome - like a detroit diesel should, not like the 4 strokes they make now.
2:50 sounds like mazda RX7
At a minesite power station where I used to work, there were 5 EMD (Electro Motive Diesel, owned by Detroit) ex-locomotive 20 cylinder two strokes connected to 3.3kV 4 pole alternators, producing 2.1MW peak power at 1,500RPM (50Hz) each that were left over from the very start of the mine.They had an unusual exhaust scavenging system which consisted of a large diameter centrifugal blower bolted to an axial turbine which was fed by exhaust gases. The blower was driven from the crankshaft via an overrunning Sprague clutch. Up to about 1.6MW, the blower was mechanically driven. Above 1.6MW, it was increasingly driven by the turbine, making it a turbocharger. The increasing pressure & density of the exhaust gases as the engine generated more power caused the blower to spin faster than the mechanical drive thanks to the sprague clutch making for lots of scavenging air.
We also had a back-up 415V, 600kW generator driven by a Detroit 16V two stroke with quad turbos. It made a beautiful throaty snarl & looked very impressive at night with its turbos & exhaust manifolds glowing red at full power.
There is no better sound than an old Detroit, and never will be.
71's rule!!! The 71's use a dry liner instead of the wet liners in the 53's and 92's. The 71's are nearly indestructible, they just don't brake in the natural configuration. I have two 4-71's that started in August 1980 and now have 65,000 hours on them, never had the heads off, still going strong. (1400 rpm max marine use - rated 115 hp at 1800 rpm)
Agree, the 6-71 in-line was the peak of awesomeness, massive main and big end bearings, understressed and overbuilt. I've had them in prime power generator use run 30,000 hours plus at 1500 rpm and 100KW all day and all night. Stop them about once a fortnight to change the oil.
All detroit 2 srokes have a blower for pushing intake air in and exhuast out .
Never forgot and loved the way an old fellow talking about Detroit 2 Stroke fuel consumption,,,he went it sounds like this,,,,,, Dollar,Dollar,Dollar,Dollar,Dollar,endless,,, loved it,,That hunting sound,,,
Interesting fact the 16v71s are just 2 8v71s bolted together super simple how it needs to be🤟🏻
The Series 71 Engines have witnessed generations of Diesel engines come and go, a d they will continue to do so.
Their service record is UNPARALLELED!
Hey VisioRacer, you're videos are getting better and better ( btw they are awesome). And it's very cool that you also make videos about cars from the GDR, Czechoslovakia, USSR. Because I know these cars very well. And I love videos like this (because Detroit Diesels are amazing)...
I work on tugs. We don’t have many 2 stroke detroits left but I love the way the sound starting up.
I really enjoy all your videos, never boring.
The 1974 Kenworth W924AR at 05:39 is a Australian factory built 12V71 Detroit powered truck
Do you know where abouts this bloke is located mate? I'd love to see it
Adrian Hopper that truck is in Orange, NSW, Australia
Thank you for the excellent video. And yes, the jimmys are reliable if somewhat less sophisticated than the competition.
Good to know then!
Barnekkid Reliable, simple to repair, and made money for the truck owner.
It should be kept in mind that the basic design was developed in the 1930's. Many folk say they were thirsty and gutless, but are comparing them with engines developed 50 years later. The fact they still make some of these for the US military has to say something for them. Besides, they sound good at any speed, and apart from exhaust noise, they are fairly quiet mechanically, and don't rattle at idle like a bucket of bolts like most modern four stroke diesels do. To listen to, they are like comparing crisp toast to a soggy crumpet.
Best vid that you ever did. I love the scream'n Jimmy's.
I love Detroit Diesel! When I was playing ETS2 1.27 I always had a Peterbilt 351 with a 6V-92 next to my regular truck, and that Detroit Diesel sounded so realistic! I loved it! :D
So the classic hotrod 8-71 blower originally came off an 8-71 detroit diesel? Cool.
Actually it was a 6-71 and only the one that came off of an inline Detroit 6-71. The hotrod 8-71, 12-71and 14-71 blowers only come from hotrod blower shops and were never installed on a Detroit engine.
If I remember correctly the 12-71 had 2 6-71 blowers on it
The 8V-71 did have an 8V-71 blower on it. The 16V-71 had two.
Had a 8v71,1973 white Western star ,got in running backwards one day slipped the clutch almost stalled it engine bumped back and oops no oil peasure exhaust coming out air cleaner and forward gear became reverse,pulled air shut,had to stall it to stop,Good times sceaming ass engine.
Yes, I saw that happen with a 6-71. Didn't run smooth, but still ran backwards
Last one I worked with was on 0:38 a brand new Western States pumper. 6v92 Silver with DDEC. Ran so sweet!
That 6V92TA where the guy had the vice grips on the rack (common to do on a rebuild to make sure the governor and injectors work correctly) puts out a lot more that 280 hp in marine trim as this one was . More like 535-550 .
The term 'runaway' is what happens when you let your helper run the rack for the first time on a 6V53 and he runs the buffer screw in a little too much and rather than putting a board over the blower (or tripping the emergency air shutdown) therefore inverting the blower seals in the just overhauled blower , takes off running from the screaming engine that's floating valves . That would be you , Todd . I certainly hope you called 1-800-Be-A-Chef by now .
You completely skipped the 6/71 straight 6 238hp. Those engines were designed in1938 and prolific on/off road through the 60's - 80's. Emissions is what killed them.
They also made a silver 8v92. It was in a international transtar 2 and was powerful and fast for a semi truck!
best sounding one too
We had (I think 10) AM General transit buses with 8V-92 turbos. I loved those engines.
Dave Luttinen back in the early 90’s we had two 8v92 twin turbo buses at Greyhound, they weren’t allowed in Cali even back then. You could hit 85 mph in third gear.....just badass in a 25 ton coach. It was the MC9 model from MCI
My grandfather drove a truck with that. It sits where i work and unfortunately it would need work to get it running
@@skeezix8156 My 8V92 experience was in a Eagle coach with an automatic. That thing would pick them up and put them down. I did tend to prefer the sound of the 71 however.
Great collection of restored trucks on the 12/71 powered Australian Kenworth roadtrain, I drove White Roadboss's with a 6/71 Detroit for an oil company in Australia, 13 speed Road Ranger and full Jake breaks made them a very distinctive sound when working.
Long gone now but a part of trucking history.
My favorite though was a Mack Superliner with the an upgraded 550 hp E9 V8 Mac 12 speed Mack box , great engine great sound.
Hi VisioRacer,
You've just made my day! Two stroke Detroits are a very rare sight on the road in Australia these days. However, when I was a kid, my Dad was driving tourist coaches that were powered by Detroits. There was a 4V53, several 6V71s and 92s and also some 8V71s and 92s. They all sounded wonderful and even had a pleasant exhaust smell! Ah, those were the days. 😎
Cheers,
Tim
Tim Banicevich the 8v92 with a v drive in the 1950s MCI coaches were a pleasant drive.
roundsm18 Now there's a name I almost forgot. Greyhound Australia had Detroit powered MCI coaches until the end of the 1990s. They were magnificent machines.
Best motors ever built!
I would love a pickup with a Detroit 2stroke like riding a Harley Davidson
They have a distinct sound
Love the sound of a big
2 stroke diesel
AWESOME especially that truck right at end, would to see that bad boy driving!
My Dad used to say, the Detroit was only good for giving your left leg a workout downshifting.
@Edwin Orantes BULLSHIT.
@Edwin Orantes bahahaha! Nope.
our engine rebuilder says that you should run the engine like you hate it. since they are well governed, thats what we do. low speed and idling are death for these engines
A lot of guys around here said that too. They hauled a lot of rock in semis with 6-71s.
josh m Yep. With the two stroke Detroit engines you had to drive it like you stole it.
My Dad always said that as you got in the truck to Take Off, you should set your hand in the doorjamb, and SLAM the door shut on it. THEN you would be in the *CORRECT* Frame-of-Mind to Drive it RIGHT.
Yea once ya have oil pressure and shes good for a minute, put a load on it or else ya might not seat the rings.
When done right, rings are seated within minutes, and the rest of break in period is just lettin the bearing surfaces get comfy with each other.
2:16 I’m in the video in the bleachers. Top row second bleacher on the left side side. This was at irricana pioneer days 2015
I have had many Detroit's over the years but my favorites are always going to be the 6v53, 8-71, 6-71 and the 6v149
Ever ride on a Trailways Silver Eagle coach with an 8V-71 and dual Donaldson exhausts? That was almost as good as riding with the Glenn Miller orchestra way back when!!!!!!!
@@Disques13Swing no that was before my time but my dad drove them, he liked the ones with the 12V71 and the 5 speeds
Imagine if a company made a diesiel powered muscle car
Cartoonz n Cereal BLASPHEMEEEHH
Cartoonz n Cereal it would get dragged
That would be dodge. they could put a straight 6 turbo Cummins into something like the challenger or make an entire new line of muscle style cars.ahh think of the possibilities lol
Cartoonz n Cereal look up the duramax camaro and powerstroke mustang, there's a company that actually didnit
ForRealBruh 01 that was an aftermarket conversion, I believe the company that did it would build you one, but it costs tens of thousands
Dude! I can't believe you mentioned Brockway! I am from/currently living where Brockways originated from! We recently had a 3-4 day event dedicated to them!
Amazing. Great video.
Awesome video and insane, 2stroke Detroit’s king of the diesels 👍.
Lol the people stand around your truck think its screaming to 8k when its at 2k (yes i know they dont rev to 8 but its what it aounds like hahahaha)
8:08 Imagine that thing running away hehe.
Lol good times
Been there done that and lost the tee shirt tring to shut it down . Lol.
I love the way they cut the 1:56 clip with a smile on his face and the rpm's in the ketchup.
love them old Detroits
