I bought #2822 1990 ZR-1 back in 2018 with 74k miles on the clock, it had been just sitting for many years. I had a lot of maintenance work to do on her, got tags and insurance in May of 2020. Have driven her over 8k miles so far. I drive this bad boy as much as I can, it's a blast to drive and runs great. Still have work to do, but figured I would enjoy it while I continue to work on it. I remember when they came out, way out of my price range, can't believe I actually own one now, pretty cool.
Hard to believe you did a video about the C4 ZR-1 without even mentioning the multiple FIA World Land Speed Endurance Records set by Morrison Motorsports in 1990. Those records were only eclipsed years later by a one-off, purpose built prototype race car, and they still stand TO THIS DAY for a production car.
well racing is not see what car is more fast if so any comercial four door saloon can beat it ,to go straight ahead ,it´s not racing and those speed contests are not in a regular car
Sorry, but yes, they were stock cars. It was a very impressive feat. The cars they used could have gone longer, but the drivers became exhausted and had to stop. @@RUfromthe40s
I own a 1995 ZR-1. Its one hell of a car! The LT5 engine steals the show. It FOR sure has more power than 405hp. My but dyno says around 440-460hp. The LT5 pulls hard all the way to redline with ease and its real party trick is the 60-90mph. It all ways puts a smile on my face when i drive it! For what i payed for my ZR-1 i stole it. Now if you can find one in ok shape for any price is hard but still very worth it. The car is amazing and i cant say enough good about it, just buy one.
I was six back in 88 when my dad bought his first Corvette. He purchased a book from Lingenfelter and pulled out and rebuilt the 350. I always had fun with him in that car. We have had 4 Corvettes in the Family since then. I miss my C5. I used to think my shit didn't stink when my mom would drop me off at high school in her 95 Vette. Fun times
Early C4s were "not all that fast?" And yet they went undefeated for 3 years straight (as in they won EVERY race) from '85-'87 in SCCA Showroom Stock. In fact, Porsche and Lotus got so butthurt they got together and had the Vettes banned from the series and they were forced to race against themselves in Corvette Challenge.
@@bluesky-ud9wg Race car??? Yeah I guess if a professional driver, some decals and some safety equipment makes it a RACE CAR then yeah... What part of "SCCA SHOWROOM STOCK" did you miss? It's called SHOWROOM STOCK for a reason. You must've graduated at the top of your f'ing class... just because someone makes a TH-cam video does NOT make them an authority on the subject or on history.
@@sidefx996 Haha, the C4 was terrible, period. So it won showroom stock, does that make it a good car? Hardly. You can love them all you want but they are terrible cars period.
The C-4 ZR-1 required 2 keys to unlock all its power like a Bugatti. Your main key went in the stock ignition switch on the column. A second key went in a switch on the console to enable “Full Power Mode.” Without the second key they only made 210 horsepower.
Haha! All that for only 33 percent more power than a Toyota Camry! (If you told someone in 1988 that the ZR1 variant of the corvette would only come with 1/3 more power than a Toyota Camry he’d find that very disappointing.)
@@juanc5149It outran virtually every car in the world on the track and street. Yes, normal passenger cars make good power these days and thirty years have changed that fact, shocker.
The 1984 Corvette with the miss-fire engine, sorry the cross-fire engine. I had the unfortunate experiance of owning one, but the 1991 ZR1 was one of my favorite Corvettes. Still love the wheels. I forgot the Corvette Sledgehammer was a beast, Callaway went nuts! 255mph.
Yeah I have heard those early c4s were just not it when it came to engine, thankfully the LT1 that they got towards the end was fairly stout even at the base model level
yeah but US people dont know about it, if they know, collectors buys, even some of them already buy, 25 year ban time passed for it, i talk a man from US said he bought 1 and waiting for transport, prices going up, i hope he didnt do that video before i buy 1 of it.
I recall the C4 demolishing the brand new 944 Turbo and large the 944 Turbo S in the 80s. As a Porsche owner at the time, it was a shock. I think that also lead the 911 on a journey to improvement from the 3.6 liter to the liquid cooled products.
@@yankees29check the statistics the 911 was slightly faster in 0-60 and 0-100 it was magazines who overcooked the zr1,,zr1 had better acceleration tho..
Thank you! I try to be very specific with the sponsors that I may partner with as I want to make sure they are legitimate and actually something the audience might find useful! No cryptocurrency companies on here LOL
Regardless of whether people thought c4 base weren't all that fast,they still easily beat all other American sports cars without even being the all mighty zr1 vette.
I own one. 1986 coup. Not real hard to get into to. A bitch to get up and out of. Dead stock 350 engine pass 70 mph. But from a dead stop....floor it and burn the tires off. Once got a speeding ticket at 88 mph. The freeway cop gave me a break. Love opening the hood to anyone that asks. Only the C4 has that racing front swing up hood.
The Vette has been my favorite car for as long as I can remember. It was the first car I could identify on sight, way back at the tender age of 3. Forty years later, my interest never waned. Oh sure, there are a lot of other cars that have populated my list of favorites, but the original King of the Road has never lost its place at the very top. In my opinion, it's the only car built by any of the big three that's any good. We've been building nothing but trash here in the US for longer than I've been alive, but the Corvette stands apart from the rest. As it should, considering it's a true "halo car" in every sense of the term.
Corvette at one point even contemplated a V12, for this they built a special test vehicle, a one off, in 1990 to top the recently unveiled Viper and its 500 cubic inch v10, It was internally called ZR-12 also dubbed „Conan“, The engine was a 600 cubic inch naturally aspirated monster that made north of 700 hp and 750 lb.-ft. If you do research you will find even some clips on here with the car driving in motion, engine sounds etc. They should have made a very limited special edition production run. God Bless America.
My 1994 stock LT1 automatic will go to 178 MPH without any trouble. The ZR-1 only had 30 more HP, it still had a governor at 178, because the tires are only rated for 178.
I was in high school back then so the C4 was my generation Corvette and I've owned several and raced them too. So I know them inside and out working on them and they are super cool and an absolute bargain today. I think the ZR1 really was a bit late to the market with a flurry of magazine tests for the '89 MY year in Europe and then the car didn't make it to market until 1990. The 1990 interior redesign is particularly atrocious unfitting for an economy car let alone a sports car so while the car had a great engine the rest of the package plus the "sill" wasn't going to win over very many Porsche operators. I think the '91 C4 body update and then the Viper just killed all the buzz with this car. In reality the pushrod engine was easily able to hit 300HP in 1985 with the TPI had it been not sized for a 305 engine, had higher flowing heads, and better exhaust. You can literally cover the exhaust manifold on an L98 with a quarter. I did just that with a mild 211/219 cam on a 1990 and ran 13.0s@108 in a convertible on street tires. GM got lazy, spent a lot of money developing the LT5, which lit a fire under their powertrain division resulting in the LT1, LT4, and then the LS1. The ZR1 lit quite a spark and is a 1000% awesome car for those that know .
@@themaninabucket8365 if you ever drove it you would know it´s a wankel engine and still goes like in the day i bought ity , the only problem with wankel engines is the mandatory maintenace also have a SAAB 900Turbo , a 9000turbo both with wankel engines and all are fine ,only did what came in the book as maintenace ,the most seen problem is that at the end of several thousands of km´s the rotor as to be substituted and no one would do it , too expensive , well if it had any problem would be but they were built perfect so it´s a myth all about wankel engines, i have two more 9000 turbo but from the early 90´s that instead of a big window in the back ,they reduced the size of the glass and made a litle car trunk to avoid the expense of makin`it big but all rest of the car is the same, the luxury is amazing as the Saabs always had since early 70´s when i bought the first one. the Mazda i only bought it because my father had bought the early model who was amazing good but in 87 the 2 seat car was perfect as the driving position was above of many other more expensive cars , not that this wasn´t but a type of engine that wasn´t the regular with a lot of power , check it if you doubt it
PLEASE DO THE 1ST GEN ZR1!! They are so unknown, underrated and under appreciated. You've got my sub you have an awesome channel here and I wish you the best growing into a well known channel. Also something on the L88's AND the little known L88, L89 transplants that took place...
i like that it looks like a regular c4. if you want to know with hood closed just notice the space on either side of the license plate where the extra wide is
I may or may not be the first to mention, but when the ZR-1 was produced, the company making the T-56 6 speed transmission was Borg-Warner, not ZF. Borg-Warner was later purchased by Tremec.
even? it´s the only to have if your not filphy rich, i have three corvette´s from the 60´s two from the 70´s my last was a special edition of the barbie car don´t understand the C1 or 2 or5 it don´t make any sense ,which are the ones that doesn´t count?
@@RUfromthe40s I remember attending a classic car meeting at Modderfontein. Next to my car was a Callaway Corvette. That was also not bad looking. Incidentally my car was a stock standard 1988 Ford Sierra 3.0 GLX. Due to it's extremely nice condition it actually drew a crowd too.
A lot of these videos spend too much time comparing the car to current cars. It still holds up now, but the advancement that it was when it came out was beyond anything the world had seen at that point.
The Mercury built overhead cam motor was a real performance car. I had a Taurus SHO with a Yamaha motor cycle overhead cam and a 5 speed Mazda built 5 speed stick that was a street sleeper. It was the fastest Ford in 1989 although Ford ruined it with the later SHO’s by changing the motor and going to an automatic.
@@bluesky-ud9wg I say that because alot of ppl take the Corvette as a a joke- The corvette makes me proud & I just hate when ppl wont give a car credit
The 1963 375 HP fuel injected 327 Corvette went toe-to-toe with the European cars and held its own quite well (I would argue that it won), so your closing statement is wrong.
I’m not familiar with the ZR2 having a Lotus engine. The ZR2 “Big Doggie” project has a Chevy big block 454 that has similar performance to the Lotus engine model at less price. Rumors were that contract restrictions required the Big block project to be killed so only 1 ZR2 (Big Doggie) was built from a mule. I believe I saw it sold at Barrett Jackson as part of a collection. Google Corvette ZR2 “Big Doggie” and you’ll see all about it.
Even bigger is finding some shop that can help trouble shoot issues that pop up. kind of a downside. I pasted on a 90 ZR! with 17.000 miles. It was out of a collection. The price was right. But any 30 plus year old will need servicing, and the Chevy dealer was telling me that due to its age they didn't have any tech that had worked on an LT5. I held off looking for anybody who worked on Corvettes in my location. I do most work myself on everything I own. Minus my wife's new car under warranty. Truly disappointed that I couldn't find anyone who would touch it. Yes, some parts are no made anymore but I have found that networking with other C4 owners to be a big help on my 90 C4 with just the L98. Yup had to past on the ZR1. For me the cost and what ifs out weighted the driving enjoyment.
Unfortunately, this particular corvette design was made with inadequate legroom for taller drivers. I'm six foot four, with 36" inseam pants, and though I could jam my legs into the car, I couldn't move my legs at all once in it. This is what pushed me to a Porsche 928, which had both more legroom (adjustable seat bracket mounts, and moveable pedal brackets, too). Wound up being a great decision, that Porsche was the best car I ever drove.
Same....its the sport seats and that crappy steering wheel. Put an aftermarket in it and swap out the standard seats in place of the sports and way more comfy. I could only drive mine for an hour before my hip was on fire Auto C4 was fairly comfortable no problem. Loved the 928s but knew I couldnt maintain one on my own
I’m 6’4 and the C4 is the only Corvette I could get comfortable in. You must be all legs and no torso, because the 928 has awful headroom, especially with the sunroof.
I always thought that horizontal molding made the C4 look cheap. Black C4’s looked better but only because the black molding matched the color of the body so wasn’t as obvious. I suspect this was the reason why the C4 has been the least popular corvette.
These cars seem to be making a comeback because of TH-cam vloggers like you. The value of the C4 Corvette is now skyrocketing due to the economy. If you decide to buy one of these cars, the good thing is a lot of the owners take good care of there C4. Unless you buy one from a junkyard to start your own build.😎😎😎😎
Didn’t GM do a twin turbo V8 Vette in ‘94 ish? Calloway or something like that? Btw in this era the Buick Turbo 6 was a real powerhouse idk if that’s the same turbo 6 in the cyclone
The Buick was the 3.8 V-6 which was actually Buick's design. The Syclone/Typhoon used the 4.3 which many call the baby SBC because it shares much. Both are great little engines that can take a beating. Especially the 3.8. GM slapped Superchargers on them in latter years. They were notorious for torque steer N/A so you can imagine how they were with a blower. I've had both and enjoyed them.
@@presmasterflash7555 Syclones were only offered for 1 year and Typhoons I think only ran 3 or 4. They were expensive for 1 but their #1 sin was they beat up on the Vette. Same as the GN, GNX and the Turbo T/A for '89. So not a lot of people have gotten to experience them.
the only corvette c whatever from late 80´s that had some driving quality was like this because european engeniers took over the most hated corvette of all times, i own one that it´s a special edition bought it cheap but it´s the better one, Barbie destroyd this model for everyone, it´s nice to drive it´s fast but not the best car,when buying it in England i made a 4.000km trip to portugal going to see some friends in the netherlands so i made it with a 2nd hand corvette i knewn nothingf about it but no problems dring it´s 4.000Km trip after being stoped and not knowing it´s history ,it must be a good car ,only paid 7,500€,mettalic grey car
I’ve found three of your posts, and they are just totally wrong. What European engineers are you talking about? The C4 was totally American designed. When they built the ZR1, yes they got Lotus involved, as they were owned by GM at the time. But even the engine was jointly Chevy and Lotus, not all Lotus.
@@ErikDB6 dude you seem to no nothing about cars ,this is for men with beard, not for kids that were born yeaterday C4 what about the C1,C2,C3, so in 69 the C4 was released after that ,what?dude say something being a Dude you´ll have something to say or just Dude all ,boy, "totally american built, then Lotus...."lotus is a euriopean brand and made some of the best handling cars, i still have my Europa from 72 ,allthough i don´t fit in it anymore i like it so much that i´ll never seel it or maybe loose some 40 kg or a bit more so i could drive it again,Dude and european GM as after owned by the south koreans or maybe you haven´t noticed that there is no longer a chevrolet corvette but a corvette with the litle two crossed flags as in more fast Chevrolets like the 65 and 67 impala coupé
to what 911 are you refering, as i have a 85 911 turbo and a 89 corvette made by etc.,etc., lot´s of talk but bought it some years ago by 7500€ in England ,than drove it till the north catch a ferry ,the netherlands where i also have family and friends and then till south of Portugal and i thought it was not that good but was perfect only drinked more than it´s owner ,either than this was smooth sailing ,made 4.632km´s without any problem ,and it was cheap maybe because it had the steering wheel in the right side wich is the left side .
destroyd, burning adjectifs by the second, i´m seeing a corvette passing by a porshe 911 turbo and it all falls apart the porshe driver seats on the floor with the steering wheel in his hands
7,200 rpm in the 90s, first Gen Miata spun to 7 grand. Crazy what newer cars can do now. My 2017 civic turbo is 0-60 in 7 seconds flat. That's 80s Ferrari numbers lol
1987 mustang gt 5.0 5 speed could get to 60 in low 6 seconds range stock. I don't think 80s supercars were doing 7 0-60s or the mustang was insane fast in the 80s compared to everything else.
1996 mustang cobra with the 4.6 4v motor Rev to 7k stock. Pretty awesome engine to be in a mid to high 20 something thousand dollar mustang (at the tIme)
Quick correction: it was the 1989 model year, not 1990 that Chevy brought back the ZR-1 (the original ZR-1 was simply an optional performance package for 1963). Also, all the base model Vettes had a 6-speed manual as standard equipment for all the years the C4 ZR-1 was available. Chevy did not indeed upgrade the tranny from 4-speed manual to 6-speed manual just for the ZR-1.
well in 65 they releaed the most fast car in the world , but only for a couple of monthes till mercedes only tunned diferentelly a family saloon, a SE as always
@@RUfromthe40sDude. You really have no clue about automotive history. Mercedes made nothing in the 60s that was close to the world’s fastest. Nor did Chevy. The Stingray had horrible aerodynamics.

@@RUfromthe40s Corvettes were always affordable performance cars. Mercedes makes mostly high quality luxury cars. At least they did. I’d take Corvette reliability over Mercedes reliability now. Chevy and Mercedes did the same thing. Same basic car with different engine options. W116, for instance, offered two straight sixes, gas and diesel, a 4.5 litre V8 and a 6.9 litre V8. All at the same time. Plus two different wheelbases. The C8 is the only generation of Corvette not to offer a manual transmission. Corvette take rates for manuals have always been very high. The Hyundai vs Camaro thing makes no sense at all, so I won’t bother commenting.
@@mikepierce4739pushrod gm guys always overhead cam motors are "overly complicated" when they really aren't they're just different from what you're used to.
Who cares what they're worth! If they're stuck in a garage to be "seen", you do you. I'd rather have something I can drive and enjoy. TBH, I'd rather build my own. Say a C-3 with 30+ years of innovation plugged into it? But that's just me. Recipes for unassuming Beasts rattling around in my Nugget.
And yet only one of them holds multiple FIA World Land Speed Endurance records that still stand TO THIS DAY for a production car. Hint: it's NOT the 911.
TH-cam SUCKS!!!!! Interrupting a video in the middle of a word is piss-poor taste. It guarantees I SHALL NOT consider the trash/trinket being hawked!!!!!

Isn't it insane how little horsepower they were getting out of those cars whereas now a standard hot rod motor out of 350 cubic inches could easily get well over 500 naturally aspirated horsepower
@@stereolababythey couldn't pass emissions and get that power reliably back then. The tech today is far beyond what it was then and fuel is also much better allowing for more compression etc. The newest 6.2 c8 base only has 495 hp from 6.2 liters and modern tech. So honestly it isn't making that much more considering this is a 5.7 and 40+ years old.
Corvettes are a nice name badge and all but you can't compare that car to ones that are just simply better built. Like one annalist said, " so sleek so fast, so shoddily built"
Yea the cars that are "better built" cost way more. You can have performance on par or ahead of those snobby euro guys and badass looks for a fraction of the cost at the cost of some build quality. It's for guys who don't need a purse. If that isn't for you guess you need to pay the extra dough for the 911
The 1990 Corvette ZR1 is a good model for the C4 but only ran low to mid 13s. A 1980s Porsche 930 would smoke the ZR1. The 1990s 964 would smoke it even worse. I'm talking about factory stock, what are you talking about?
You might want to double check your numbers. It was more like mid to high 12's according to car and driver. A 1990 911 turbo was a mid 13s car, again according to car and driver. So what are you talking about? The ZR-1 was one of fastest production cars in the world when it came out and considered the best handling car. It beat the 930 in every instrumented test and cost half the money. The C4 ZR-1 was an amazing car let down by GM itself. When you make a super Vette that looks just like the normal one but cost double the price it's a pretty tough sell to most people just looking for a flashy car to cruise around on the streets with. I love my C4 ZR-1 and wish it got the respect it deserves.
Actually any one test of any car, especially 1/4 times can vary quite a bit. It depends on the car, the climate, the driver and the tires. Power to weight ratio might be a more accurate factor of which car has more potential. What I know is my basically stock 82 930 turbo would run a 13.2/112 and the 3.6L engine in the 964 was a stronger engine than my 3.3. I googled for results on this but google is full of crappy info much of the time. The ZR1 was a cool variation from the fairly slow normal production C4, so good that GM did something cool towards the end of the run. @@MrNeon2002
Exactly, there are lots of variables with the test, but getting numbers from the same magazine rules out equipment and driver inconsistencies. If you look at the pool of data the ZR-1 is quicker on average. Mine is completely stock and from a 45mph roll I stayed right along side my friend in his stock c5 Z06. Which is a lighter car with more aggressive gear. Your power to weight theory doesn't quite work if the manufacturers aren't honest with their power numbers...
With a clutch destroying start, a 911 Turbo of the era could just take a ZR1 in the quarter. But from then on, it was all ZR1. At 150 mph, the 911 was disappearing quickly into the ZR1s rear view mirrors.

Yeah I have heard those early c4s were just not it when it came to engine, thankfully the LT1 that they got towards the end was fairly stout even at the base model level
you could drop a modern LS into an '86 and be amazed
Should do a video of the Lotus Carlton...
yeah but US people dont know about it, if they know, collectors buys, even some of them already buy, 25 year ban time passed for it, i talk a man from US said he bought 1 and waiting for transport, prices going up, i hope he didnt do that video before i buy 1 of it.
A coworker had one and took me for a ride. I thought the tires were going to fall off the rims. Wicked fast
I recall the C4 demolishing the brand new 944 Turbo and large the 944 Turbo S in the 80s. As a Porsche owner at the time, it was a shock. I think that also lead the 911 on a journey to improvement from the 3.6 liter to the liquid cooled products.
yes ,i know it ,that is impossible to happen i have both cars ,the problem with US cars is that they don´t turn or handle well
@@RUfromthe40sthe corvettes were a lot cheaper at the time no???
@rufromthe40s You mean the car that Porsche couldn’t beat in any race for 3 years straight couldn’t handle? That’s Plain stupid.
@@yankees29check the statistics the 911 was slightly faster in 0-60 and 0-100 it was magazines who overcooked the zr1,,zr1 had better acceleration tho..
@@talhazubaer9108 huh? I never said anything about that at all but ok….
I remember my friend’s dad was a truck driver got this car. He rarely drove it. He would wash it even if he didn’t drive it. like it was his body

Pretty cool stuff. Didn't know that the motor was the only one not designed by Chevy.
lotus/chevy designed, chevy produced. its a chevy motor.

Congratulations on getting a sponsor... you deserve it...
Thank you! I try to be very specific with the sponsors that I may partner with as I want to make sure they are legitimate and actually something the audience might find useful! No cryptocurrency companies on here LOL
Regardless of whether people thought c4 base weren't all that fast,they still easily beat all other American sports cars without even being the all mighty zr1 vette.
I own one. 1986 coup. Not real hard to get into to. A bitch to get up and out of. Dead stock 350 engine pass 70 mph. But from a dead stop....floor it and burn the tires off. Once got a speeding ticket at 88 mph. The freeway cop gave me a break. Love opening the hood to anyone that asks. Only the C4 has that racing front swing up hood.
The Vette has been my favorite car for as long as I can remember. It was the first car I could identify on sight, way back at the tender age of 3. Forty years later, my interest never waned. Oh sure, there are a lot of other cars that have populated my list of favorites, but the original King of the Road has never lost its place at the very top. In my opinion, it's the only car built by any of the big three that's any good. We've been building nothing but trash here in the US for longer than I've been alive, but the Corvette stands apart from the rest. As it should, considering it's a true "halo car" in every sense of the term.
I’ll never forget the first time I saw one of those in 1984. I was on the highway. 18 years old. My mind was absolutely blown!!
Corvette at one point even contemplated a V12, for this they built a special test vehicle, a one off, in 1990 to top the recently unveiled Viper and its 500 cubic inch v10,
It was internally called ZR-12 also dubbed „Conan“,
The engine was a 600 cubic inch naturally aspirated monster that made north of 700 hp and 750 lb.-ft.
If you do research you will find even some clips on here with the car driving in motion, engine sounds etc.
They should have made a very limited special edition production run.
God Bless America.
Would that engine have anything to do with the TVR Speed 12? I'm not suggesting that I know anything, only the stats seem very close...
My 1994 stock LT1 automatic will go to 178 MPH without any trouble. The ZR-1 only had 30 more HP, it still had a governor at 178, because the tires are only rated for 178.
I was in high school back then so the C4 was my generation Corvette and I've owned several and raced them too. So I know them inside and out working on them and they are super cool and an absolute bargain today. I think the ZR1 really was a bit late to the market with a flurry of magazine tests for the '89 MY year in Europe and then the car didn't make it to market until 1990. The 1990 interior redesign is particularly atrocious unfitting for an economy car let alone a sports car so while the car had a great engine the rest of the package plus the "sill" wasn't going to win over very many Porsche operators. I think the '91 C4 body update and then the Viper just killed all the buzz with this car. In reality the pushrod engine was easily able to hit 300HP in 1985 with the TPI had it been not sized for a 305 engine, had higher flowing heads, and better exhaust. You can literally cover the exhaust manifold on an L98 with a quarter. I did just that with a mild 211/219 cam on a 1990 and ran 13.0s@108 in a convertible on street tires. GM got lazy, spent a lot of money developing the LT5, which lit a fire under their powertrain division resulting in the LT1, LT4, and then the LS1. The ZR1 lit quite a spark and is a 1000% awesome car for those that know .
I 'almost' wished that Buick had 'let' Lotus have-at the GNX/GMC-Cyclone V-6, and made an OHC head for such w/Blowers and/or Turbos!
How about doing a video on the B2K Option, Twin Turbo Charged, Callaway Corvette's of 1987-1988-1989-1990-1991.
the mazda RX-7 bi-turbo from 87 the two seat car, (i´ve seen only 2+2 models)would rip any of those cars with a 1.3L engine
@@RUfromthe40sI cant help but doubt that
@@themaninabucket8365 if you ever drove it you would know it´s a wankel engine and still goes like in the day i bought ity , the only problem with wankel engines is the mandatory maintenace also have a SAAB 900Turbo , a 9000turbo both with wankel engines and all are fine ,only did what came in the book as maintenace ,the most seen problem is that at the end of several thousands of km´s the rotor as to be substituted and no one would do it , too expensive , well if it had any problem would be but they were built perfect so it´s a myth all about wankel engines, i have two more 9000 turbo but from the early 90´s that instead of a big window in the back ,they reduced the size of the glass and made a litle car trunk to avoid the expense of makin`it big but all rest of the car is the same, the luxury is amazing as the Saabs always had since early 70´s when i bought the first one. the Mazda i only bought it because my father had bought the early model who was amazing good but in 87 the 2 seat car was perfect as the driving position was above of many other more expensive cars , not that this wasn´t but a type of engine that wasn´t the regular with a lot of power , check it if you doubt it
The "ZR-2" prototype WAS actually built and it was with a 454, not an LT5.
A ZR-1 Original video would be perfect!!!!!
I will add it to the list!
I'd like to see content on the original.
Wouldn't it be easier to just look it up and read about it yourself?
Happy to make a video on it!
The 1985 Corvette set the performance world on fire when it went 155 MPH at Mid-Ohio.
would love to see a c3 zr1 video
PLEASE DO THE 1ST GEN ZR1!! They are so unknown, underrated and under appreciated. You've got my sub you have an awesome channel here and I wish you the best growing into a well known channel. Also something on the L88's AND the little known L88, L89 transplants that took place...
i like that it looks like a regular c4. if you want to know with hood closed just notice the space on either side of the license plate where the extra wide is
I may or may not be the first to mention, but when the ZR-1 was produced, the company making the T-56 6 speed transmission was Borg-Warner, not ZF. Borg-Warner was later purchased by Tremec.
ZR-1 had a 3.45 rear gear not a 3.33
Please do the original ZR1
To me even the Corvette Stingray is a really good looking car.
even? it´s the only to have if your not filphy rich, i have three corvette´s from the 60´s two from the 70´s my last was a special edition of the barbie car don´t understand the C1 or 2 or5 it don´t make any sense ,which are the ones that doesn´t count?
@@RUfromthe40s I remember attending a classic car meeting at Modderfontein. Next to my car was a Callaway Corvette. That was also not bad looking. Incidentally my car was a stock standard 1988 Ford Sierra 3.0 GLX. Due to it's extremely nice condition it actually drew a crowd too.
I know about the ZR1. GOT destroyed by one on the open road just south of Aspen Colo. DIDN'T even spund like a regular car, sounded like a motorcycle.
I'd like to see the 1st zr1 video and a Saleen video thanks great show
A lot of these videos spend too much time comparing the car to current cars. It still holds up now, but the advancement that it was when it came out was beyond anything the world had seen at that point.
GM has a long history of kicking ass.
Please do a video on the 70 zr1,it's in every video game, also great video as always
Good luck finding one .
Look up the 70 LT1 pretty much the same car drivetrain etc.
The Mercury built overhead cam motor was a real performance car.
I had a Taurus SHO with a Yamaha motor cycle overhead cam and a 5 speed Mazda built 5 speed stick that was a street sleeper. It was the fastest Ford in 1989 although Ford ruined it with the later SHO’s by changing the motor and going to an automatic.
Great history of this ZR1 corvette!!👍
I don’t remember a failing economy in the mid 90’s. Also the LT4 kicked the LS1’s ass so the LT5 would’ve had no competition
the 2009 zrl is sooo underrated-
It is that car is a monster!
I drive with it on Gran Turismo 6...jeezus.. I be setting records doing sub 7 nurburgring runs@@rarecars3336

@@bluesky-ud9wg I say that because alot of ppl take the Corvette as a a joke- The corvette makes me proud & I just hate when ppl wont give a car credit
@@MrCalverino Regular vettes are a joke but the special ones aren't. A red, white top conv, auto are a joke, a 2002 zo6 isn't.
That's cool Chevrolet had a Corvette back in the 90s that competed very well with Europe's best sports cars.
Corvettes always “competed very well” with Europe’s best sports cars.
There was a Twin Turbo V8 Corvette, and it was sold through GM dealers.
The transmission holds up just fine,.
No car guy would say just because it’s a 5.7 that it’s the same, I can’t imagine.
The lt5 also has less low end torque than the Lt1.
hey those old C4s were quite fast for their time! it's just that the 90s C4s and the ZR1s were faster
The 1963 375 HP fuel injected 327 Corvette went toe-to-toe with the European cars and held its own quite well (I would argue that it won), so your closing statement is wrong.
Such a tremendous car.
Yes! Do the C3 ZR1!
You dont even ask to use my video ?
Dude seems to do a lot of that. Stole from Camissa too.
I’m not familiar with the ZR2 having a Lotus engine. The ZR2 “Big Doggie” project has a Chevy big block 454 that has similar performance to the Lotus engine model at less price. Rumors were that contract restrictions required the Big block project to be killed so only 1 ZR2 (Big Doggie) was built from a mule. I believe I saw it sold at Barrett Jackson as part of a collection. Google Corvette ZR2 “Big Doggie” and you’ll see all about it.
I love the intake!
Just subscribed love the content
C4 ZR-1s rock!!!
Big problem is you can not get a lot of parts anymore for the LT5 ZR1 engine.
Even bigger is finding some shop that can help trouble shoot issues that pop up. kind of a downside. I pasted on a 90 ZR! with 17.000 miles. It was out of a collection. The price was right. But any 30 plus year old will need servicing, and the Chevy dealer was telling me that due to its age they didn't have any tech that had worked on an LT5. I held off looking for anybody who worked on Corvettes in my location. I do most work myself on everything I own. Minus my wife's new car under warranty. Truly disappointed that I couldn't find anyone who would touch it. Yes, some parts are no made anymore but I have found that networking with other C4 owners to be a big help on my 90 C4 with just the L98. Yup had to past on the ZR1. For me the cost and what ifs out weighted the driving enjoyment.
The LT5 has fantastic aftermarket support. Plus, the engine is nigh onto indestructible.
I own a '91 ZR1 and parts are NOT hard to find. There are several support groups and LT5 specialist always willing to help.
** oh, and lets not forget -------> 175 mph average speed for 24 hours straight too ... touch the clouds ! GOD Bless
Unfortunately, this particular corvette design was made with inadequate legroom for taller drivers. I'm six foot four, with 36" inseam pants, and though I could jam my legs into the car, I couldn't move my legs at all once in it. This is what pushed me to a Porsche 928, which had both more legroom (adjustable seat bracket mounts, and moveable pedal brackets, too). Wound up being a great decision, that Porsche was the best car I ever drove.
Same....its the sport seats and that crappy steering wheel. Put an aftermarket in it and swap out the standard seats in place of the sports and way more comfy. I could only drive mine for an hour before my hip was on fire
Auto C4 was fairly comfortable no problem. Loved the 928s but knew I couldnt maintain one on my own
I’m 6’4 and the C4 is the only Corvette I could get comfortable in. You must be all legs and no torso, because the 928 has awful headroom, especially with the sunroof.
I always thought that horizontal molding made the C4 look cheap. Black C4’s looked better but only because the black molding matched the color of the body so wasn’t as obvious. I suspect this was the reason why the C4 has been the least popular corvette.
It was a late 70s/early 80s thing. Most often seen on the Ferrari 308.
These cars seem to be making a comeback because of TH-cam vloggers like you. The value of the C4 Corvette is now skyrocketing due to the economy. If you decide to buy one of these cars, the good thing is a lot of the owners take good care of there C4. Unless you buy one from a junkyard to start your own build.😎😎😎😎
G Gordon Liddy bought one of these. Sent it to Lengenfelter for a bit of breathing upgrade.
Tag on it was H2OGATE😂
i am happy for you having sponsor, good work. please dont make video about lotus carlton (lotus omega), dont teach that car to collector people.
Thank you! I love the way you phrased that hahah
I never get tired hearing about my car, lol
Was wondering why the Callaway sledge hammer option wasn't mentioned????
So we can make a separate video on it :)
Sledgehammer was only a prototype.
It's one of those designs that gets better with age.
Didn’t GM do a twin turbo V8 Vette in ‘94 ish? Calloway or something like that? Btw in this era the Buick Turbo 6 was a real powerhouse idk if that’s the same turbo 6 in the cyclone
The Buick was the 3.8 V-6 which was actually Buick's design. The Syclone/Typhoon used the 4.3 which many call the baby SBC because it shares much. Both are great little engines that can take a beating. Especially the 3.8. GM slapped Superchargers on them in latter years. They were notorious for torque steer N/A so you can imagine how they were with a blower. I've had both and enjoyed them.
@@SGTJDerek yeah I’m very familiar with the Buick 3.8 turbo. Not so with the cyclone but I’ve had a few vehicles with the 4.3. Great motor
Callaway did the twin turbo conversions. Did 383 NA swaps also called the supernatural
@@gordocarbo I’d drive that
@@presmasterflash7555 Syclones were only offered for 1 year and Typhoons I think only ran 3 or 4. They were expensive for 1 but their #1 sin was they beat up on the Vette. Same as the GN, GNX and the Turbo T/A for '89. So not a lot of people have gotten to experience them.
Motor made and built in Oklahoma. I believe still made up to recent
C3 ZR1 would be Nice!
Ever changed the oil filter on one? 😂
There's a '91 for sale locally.
the only corvette c whatever from late 80´s that had some driving quality was like this because european engeniers took over the most hated corvette of all times, i own one that it´s a special edition bought it cheap but it´s the better one, Barbie destroyd this model for everyone, it´s nice to drive it´s fast but not the best car,when buying it in England i made a 4.000km trip to portugal going to see some friends in the netherlands so i made it with a 2nd hand corvette i knewn nothingf about it but no problems dring it´s 4.000Km trip after being stoped and not knowing it´s history ,it must be a good car ,only paid 7,500€,mettalic grey car
I’ve found three of your posts, and they are just totally wrong. What European engineers are you talking about? The C4 was totally American designed. When they built the ZR1, yes they got Lotus involved, as they were owned by GM at the time. But even the engine was jointly Chevy and Lotus, not all Lotus.

If only my 73 L82 had the suspension of the C4 Id never have sold it. Hated the way my C3 drove...looked cool though
to what 911 are you refering, as i have a 85 911 turbo and a 89 corvette made by etc.,etc., lot´s of talk but bought it some years ago by 7500€ in England ,than drove it till the north catch a ferry ,the netherlands where i also have family and friends and then till south of Portugal and i thought it was not that good but was perfect only drinked more than it´s owner ,either than this was smooth sailing ,made 4.632km´s without any problem ,and it was cheap maybe because it had the steering wheel in the right side wich is the left side .
destroyd, burning adjectifs by the second, i´m seeing a corvette passing by a porshe 911 turbo and it all falls apart the porshe driver seats on the floor with the steering wheel in his hands

1987 mustang gt 5.0 5 speed could get to 60 in low 6 seconds range stock. I don't think 80s supercars were doing 7 0-60s or the mustang was insane fast in the 80s compared to everything else.
1996 mustang cobra with the 4.6 4v motor Rev to 7k stock. Pretty awesome engine to be in a mid to high 20 something thousand dollar mustang (at the tIme)
Quick correction: it was the 1989 model year, not 1990 that Chevy brought back the ZR-1 (the original ZR-1 was simply an optional performance package for 1963). Also, all the base model Vettes had a 6-speed manual as standard equipment for all the years the C4 ZR-1 was available. Chevy did not indeed upgrade the tranny from 4-speed manual to 6-speed manual just for the ZR-1.
They introduced the ZR-1 however all the cars sold to the public were 1990 models.

@@RUfromthe40s Corvettes were always affordable performance cars. Mercedes makes mostly high quality luxury cars. At least they did. I’d take Corvette reliability over Mercedes reliability now. Chevy and Mercedes did the same thing. Same basic car with different engine options. W116, for instance, offered two straight sixes, gas and diesel, a 4.5 litre V8 and a 6.9 litre V8. All at the same time. Plus two different wheelbases. The C8 is the only generation of Corvette not to offer a manual transmission. Corvette take rates for manuals have always been very high. The Hyundai vs Camaro thing makes no sense at all, so I won’t bother commenting.

Isn't it insane how little horsepower they were getting out of those cars whereas now a standard hot rod motor out of 350 cubic inches could easily get well over 500 naturally aspirated horsepower
it's not like they couldn't get that power -they chose not to
GM had plans to release a 500hp LT5 it simply never happened. Took very little to do it
@@stereolababythey couldn't pass emissions and get that power reliably back then. The tech today is far beyond what it was then and fuel is also much better allowing for more compression etc. The newest 6.2 c8 base only has 495 hp from 6.2 liters and modern tech. So honestly it isn't making that much more considering this is a 5.7 and 40+ years old.
Drop a strong 383 stroker in an 84-90, and you'll have a car that can top the ZR-1 at a fraction of the price.

Porsches in the C4 era sell for 100-300k. How much are those shitty C4s selling for? 😂
$20-30K
why are you bragging that people are getting ripped off for a worse performing car
Corvettes are a nice name badge and all but you can't compare that car to ones that are just simply better built. Like one annalist said, " so sleek so fast, so shoddily built"
Yea the cars that are "better built" cost way more. You can have performance on par or ahead of those snobby euro guys and badass looks for a fraction of the cost at the cost of some build quality. It's for guys who don't need a purse. If that isn't for you guess you need to pay the extra dough for the 911
The 1990 Corvette ZR1 is a good model for the C4 but only ran low to mid 13s. A 1980s Porsche 930 would smoke the ZR1. The 1990s 964 would smoke it even worse. I'm talking about factory stock, what are you talking about?
You might want to double check your numbers. It was more like mid to high 12's according to car and driver. A 1990 911 turbo was a mid 13s car, again according to car and driver. So what are you talking about? The ZR-1 was one of fastest production cars in the world when it came out and considered the best handling car. It beat the 930 in every instrumented test and cost half the money. The C4 ZR-1 was an amazing car let down by GM itself. When you make a super Vette that looks just like the normal one but cost double the price it's a pretty tough sell to most people just looking for a flashy car to cruise around on the streets with. I love my C4 ZR-1 and wish it got the respect it deserves.
Actually any one test of any car, especially 1/4 times can vary quite a bit. It depends on the car, the climate, the driver and the tires. Power to weight ratio might be a more accurate factor of which car has more potential. What I know is my basically stock 82 930 turbo would run a 13.2/112 and the 3.6L engine in the 964 was a stronger engine than my 3.3. I googled for results on this but google is full of crappy info much of the time. The ZR1 was a cool variation from the fairly slow normal production C4, so good that GM did something cool towards the end of the run. @@MrNeon2002
Exactly, there are lots of variables with the test, but getting numbers from the same magazine rules out equipment and driver inconsistencies. If you look at the pool of data the ZR-1 is quicker on average. Mine is completely stock and from a 45mph roll I stayed right along side my friend in his stock c5 Z06. Which is a lighter car with more aggressive gear. Your power to weight theory doesn't quite work if the manufacturers aren't honest with their power numbers...
1990-Z ran 12.9s bone stock.
With a clutch destroying start, a 911 Turbo of the era could just take a ZR1 in the quarter. But from then on, it was all ZR1. At 150 mph, the 911 was disappearing quickly into the ZR1s rear view mirrors.
