It’s pretty crazy that Miatas and Corvettes from the same generations are converging in price. I’ve owned plenty of Miatas but always wanted a C5 or ZR-1. The 4 overhead camshafts really deliver that sports car type of power.

[@KevinJames-yg9eu]

It's not so much the power as the fact it has primary and secondary intake runners with different cam profiles so it can keep the drivability and meet emissions and fuel economy requirements using 1980s technology. The L98 could have easily made the power with a different intake manifold and camshaft, but then it would never have met any government regulations to be sellable.

Constructive criticism: an outside shot of the races would have been more informative. New tires gain traction after a bit of wear that rounds off the leading edges of the tread. They will feel feathered. Personal problems lol: I was like what gearing do you have needing to shift 3rd shortly after 30mph.. turns out you didn’t have to. Then you use the lesser 375hp ZR-1.. oh but with ported heads! I could not mind headers even and exhaust because I think that would make up the difference or close to the stronger 405hp ZR-1 but no.. and then the LT-1 could have been used as well. The closest you could get would be LT-1 C4 M6 vs stock 375hp ZR-1 and the most fair since in 92 LT-1 was out and the LT-5 made 375 that year. There would be many ways to mix and match this though and it’s not every day there is a C4 ZR owner willing to go make pulls in the winter on top of a mountain lol. All in all it was a fun comparison IMO. I do think a L98 auto around 89 would be the best 0-60 maybe better than the LT1 but in a roll definitely the LT1 >L98

I built a "what if" L98 on a 1990 6m Convertible Corvette. Short story is it ran 13.07 at 107MPH at PBIR (video is here on yourube somewhere) with street tires and a bad driver (me!). All I did was port the stock heads, size the TPI to the 350 displacement (it was sized for 305CI), deal with the small manifolds, install a mild cam, and tuned the stock computer. I think it cost me $5000 in parts and achieved what was well within Chevrolet's grasp in the mid 80's. I loved the LT5 and what it represented back in the day but the engine option was $35,000 alone and that was absolutely insane when the gen 1 small block still had lots of cheap, untapped capability. If anything good came of it, GM powertrain got motivated to actually develop the LS1.

[@One_Shot_Garage]

It would be interesting to see a rematch with some bolt-ons added to the 88. Heads, cam, intake, headers and a tune and I bet things would be dead even. A lot of people write off the L98 but it doesn't take too much to wake them up. Factor in that ZR1s typically start betwen $20-30k while an L98 C4 in decent shape can be had for less than $10k and modding a base car sounds even more enticing.

Still no comparison. The engineering that went into that LOTUS/MERCURY built LT5 means it WILL hold up to being beat on for extremely long periods of time.........and do it like it's just another walk in the park. Try modding an L98 (or anything else for that matter ) to run flat out at 180 mph+ for 24 hrs straight ( with stops for tires, fuel, driver changes bringing the speed average down to 175+ mph ).........or for 29 hrs straight to reach 5,000 miles........just try it......then get back with us. The LT5 accomplished those 2 records with only headers & open exhaust. I'm not dissing the L98 at all. I like the L98.........but there's nothing you can do to an L98 to make it as DURABLE as a bone stock LT5. No way. Why do ya think after decades, it still holds both the 24hr and 5,000 mile speed endurance records. That's nothing short of incredible. Then there's the mods you can do to the LT5.

[@Michael_Lorenson]

You'll notice the ZR-1's LT5 engine has sixteen intake runners feeding eight cylinders, so two per cylinder. The 'primary' runners are roughly comparable the standard L98's _only_ runners. The 'secondary' runner of each pair opens at something like 3,500 RPM, controlled by the ECU through butterfly valves in the intake manifold, to allow better high-RPM breathing. The 'Valet Switch' prevents those valves from opening, thereby restricting the LT5's horsepower to approximately the same (~245 hp) as the L98's maximum. Carburetors and mechanical spark distributors carried the ball for about the first 80 years of internal combustion power. But then we got widespread use of electronic fuel-injection and spark-control in the early 1980s, thanks to emissions and fuel-economy regs introduced in the 1970s. Variable pathway-length and volume intake manifolds began to appear right around 1988, as I recall, so the LT5 may have been among the first engines to use that idea. Plus, Honda introduced VTEC variable valve timing at almost the same time (again, as I recall). I think the first U.S.-market car to have it was the Acura NSX. By combining these basic concepts, adding 30-40 years-worth of improved sophistication, and likely adding a turbo or two as well, you get a modern engine.

[@SlingKing2015]

Would love to see that ZR1 tested at sea level.

[@watchandjewelryloft4713]

Yes exactly. One thing I hate about many channels. They'll be testing cars at elevation or on snow/rain. I'm down near the Gulf of Mexico. I need relevant testing lol.

[@jalee6587]

Yeah he is probably losing 50-60hp at that altitude.

[@KevinJames-yg9eu]

@@jalee6587 More than that. The air density in Denver is 82% of sea level, so that turns 375hp in 308hp.

[@CS-Loc]

@@KevinJames-yg9eu Per kinematic equations of motion, that car trapping at 109mph is basically making 360hp at altitude. So at least 425hp+ at sea level.

[@gordocarbo]

90 Should run a 12.9 driven just right In crap Ca air mine slipped and spun through 2nd to no better than 13.3/4 ranging from 108-110. For stock it was Ok .

[@anibalbabilonia1867]

Man I still remember when the zr1 first came out! It was a breakthrough in horsepower! Such legendary car! I built a 1/24 scale model of that same car back then, and I still have it! 👌😎👍

[@gabrielcollazo6835]

No it wasn't😂😂😂 the 1970 chevelle made 450hp.... I'm gonna assume u r just referring to EFI cars

[@atodaso1668]

Those old ZR1's are special, a 32v chevy!

[@roxiebeagle]

I have a 91 ZR-1. I will never sell it- it does everything I want from a performance car.

[@kevin9c1]

It wasn't until the 2001 Z06 that the ZR-1 was finally matched again. 11 years!

[@troypatillo1688]

I wish they could have brought a c5 ZO6 out. Would have been a great race for the ZR-1

[@jakejake7162]

I love my 85 c4 l98 4+3 speed. She’ll make your ears ring if you stand behind her when i rev. My dream is to turn it into something as close to the c4 sledgehammer, the story behind the engineer that kept pushing forward even though his peers told him it wouldn’t work. His persistence and dedication to his craft is something that deeply resonates with me, nothing but respect for those who chase their dreams with haters surrounding them.

[@bikingD]

These were beasts back in the day. Remember a buddies ZR1 in highschool taking on a Ferrari Testarossa and just took it down big time.

[@danziger69]

Basic bolt-on ZR-1s are still amazing. 109 trap at that altitude on an unprepped track is excellent. The L98 is handicapped by that 4+3. A T56 C5 would have done better. Please take the pillar gauges off the ZR-1. Thanks for another great video!

[@TechNoirToyclub]

Cool Video so far, but sadly the C4 ZR-1 wasn`t stock...hope you find a another comepletely stock 1990 Zr-1 to compare again. Would be also interesting to compare against a standard C4 when the ZR-1 is switched not in full engine power mode. Then both cars should be very close. But never seen a test about this yet. By the way, good 1990 ZR-1 models can do 12.8 sec on the 1/4 mile under ideal conditions. Also a c5 mit manual would be a more interesting comparison. A standard C5 manual is pretty close to a C4 ZR-1 from the start, but at higher speeds a ZR-1 pulls away continually.

[@cali2468]

An L98 C4 vs ZR-1 will not be close. L98 Corvettes run 14's stock while ZR1's can easily go bottom 13's to high 12's. 375hp > 245hp.

[@case2238]

@@cali2468 he said they would be close if the ZR-1 was in ‘Valet’ mode. Can you read?

[@dingjs1969]

Hello from the UK, have to say the C4 ZR1 is an all time favourite of mine along with the Callaway Sledgehammer, the surprise for me though was the standard C4, i wasn't expecting much but it held up very well.

[@camaro69green31]

Love this series of videos guys... keep them coming!! Would love to see a fourth Gen F-body comparo?? Z28.... SS..... WS6..... Firehawk..... ???

[@dancollins8296]

I would love to see a video on those cars.

[@michaelm3381]

Agreed!

[@chadbeaver9199]

This has been my favorite Vette since it came out. Love the content so happy this channel is so versatile.

[@StreetRacingLifeStyle]

The zr1 sounded healthy AF

[@yuris6125]

Yass!

[@johnjacobjingleheimerschmi3857]

Very Cool Comparison. I read a few years ago how these LT5 ZR1 Vettes were a bargain and only going up in value. I can see why. That engine is a work of Art IMO.

[@wg8290]

That ZR-1 is impressive for such an old car.

[@hugoschmeisser2484]

now we need to see a 92-95 lt1 vs the zr1. or a 96 lt4 vs a zr1 vs z06.

[@Matticus289]

This is the first time I've ever heard the L98 referred to as "potent". Maybe "adequate"? I don't think the C4 became much to pay attention to until the LT1 and LT4s were used Edit: not counting the ZR-1, of course

[@DHolmquistDesigns]

LT1 def would have been a better comparison. LT1-LT4 models are far superior to the L98 cars and they aren’t much more $$

[@jamesengland7461]

3 hour drive one way to show off this beauty? Well done, Jordan!

[@NWI_Steel]

That ZR-1 sounds amazing

[@cliffweatherbee6914]

My old L98 C4 ran a 14.01 @98 MPH (at about 1000 ft altitude) those cars have amazing Torque! If you can get it re-tuned or get a standalone system to run the engine, you'll be able to rev higher AND create more horsepower. Those engines were limited to about 4500 RPM.

[@nlken7175]

ZR-1 is awesome. Love it

[@403Pantera1]

I work for shaganappi GM in Calgary, One of our showroom cars is the 1991 zr1… But it’s the Shinoda built Rick mears edition, Definitely the king of the pile for C4’s. I would’ve loved to seen ours go up against these two

[@markmonroe7330]

Both Corvettes are mostly traction limited in first gear and even into 2nd. That is why the Raptor killed the Corvette in the last video from a dig. The ZR-1 especially shines best from a roll and higher speeds. The ZR-1 really shines over 100mph.

[@buildingracingvideos4714]

In 1990 they started using the LT1/3 in the C4 which put it over 300hp. My 96 was rated at 330hp.

[@Enoverdoskaffe]

Ah, the ZR-1 my dream car.

[@kevin9c1]

89 to 109 mph trap suggests a 200 hp advantage for the ZR-1 and given what they said at the beginning, that sounds just about right. Yay science?

[@jeepzjken]

They didn't call the ZR-1 the "King of the hill" for nothing!

[@taelorwatson9822]

About 2 Years ago I saw ZR1 for sale under 10k. I wish I had gone and looked at it. I knew what kind of a monster they were. I wouldn't mind having the Corvette I am old and fat so I fit the demographic. There's a couple cars I considered buying and each one of them this guy on KZbin made me regret not buying them. The other one being the 2005 E320 CDI. Found one for 2500 in 2016. Bought a 2011 Infiniti, it's been a good car, but I paid 11 K and I could have had the Vette and the Merc for almost the same price

[@davidgossage2244]

So, you are testing a modded ZR-1 against stock cars, and calling it apples to apples? And auto to stick none the less. Joke test, you know it. Do better.

[@jojokrump1998]

Zr1 still beat a c5

[@davidgossage2244]

Actually, stock vs stock, a six speed C5 has a faster 0-60 and 1/4 mile.

[@originalsoundjunky]

I have always liked C4's - and have been following the ZR-1 for some time. Thanks for this video.

[@johnnymoran180]

When the ZR-1 came out in 90 I was a teenager with a Gbody Malibu with a small block and a 175 hp nitrous kit. The car was a street racer and would dead hook on the nitrous using McCreary 265/60D15 dirt track tires.. My boss at the time bought a ZR-1 and I challenged him to a street race for a months pay ($5/hr) at the time. He wouldn't do it. I think he thought he was saving me the loss. Haha he would have gotten gapped badly.😎

[@michaelthebarbarian3380]

If you guys ever want to run against my 96 LT4 car I would be down to make the road trip. Sweet video!

[@MrIpjrobson]

Love the incorporation of the music from the commercial throughout the video.

[@WhoThisGuy515]

Need a lt1 to go against the lt5. L98 is a truck motor with it's power band, the LT1 is much more suited for the corvette.

[@roryrice8742]

I got to ride in a ZR1 prototype that my friends company was testing. It was very impressive.

[@muffinman4353]

My 2023 C8 just came in..... waited 11 months, I'm pumped!

Had a friend w a 92 zr1 and i enjoyed driving it more then my z07 package z06 it had SOUL and was raw exactly what cars have lost now since theyre all electro nanny sleds…i drove the one w the hp bump from 375 to 405

[@Ferraridude13]

Should have compared a C4 with LT1 w/6-speed, that compares most closely with the ZR1

[@neonvoid]

that was a fun test, thank you (1985 C4 base owner here :) )

[@BlacksheepLSX]

I have a 92 zr1 with a tune and exhaust.. and it walks c8s on the highway every single time.. and it's done 190mph on GPS multiple times and was still pulling

[@garrisonnichols807]

I wish the ZR-1 was completely stock to give a better representation between it and the 89 base model but still a fun video. But my favorite is definitely the 5th generation with that amazing LS1 engine. C4 are still my second favorite. I've driven both and I think the C5 is the superior choice here.

[@destruxandexploze2552]

1989 had the 6 speed manual so his is an 88.
