Hey Z28!!!!

[guitarded]

apparently there's a vid on youtube of a z06 running 10's in the 1/4 mile. He's boasting the car is bone stock....including the tires...

Anyhow, There's a fellow on another forum who believe's this to be true. I tried to explain that this is not possible....mathematical and realistically...He's not convinced, and I just want to shut him up.

in the end I just said to him.."If you think 500 hp will make a corvette run 10's bone stock, then I'm Fucking Ben Afleck!"

Could you talk to your GM buds, and provide some proof that this could not happen

Hey Ben,

Its true...

but yea some Z06 owners have been punching in the 10's with this car bone stock recently. Not many but a few. A lot of the good drivers have been all over the 11's for a while now. Even cutting 11.0's dead stock. But now some guys who have had thier cars for a while really are hitting the 10.9's
GM says 505HP but it is underated from the factory. Some Z06's are dynoing more at the wheel than the 505HP. And thats stock.:confused:

But yea the Z06 is that fast. I didn't beleive it when I first heard about it on a few forums but its happening to more than a few guys so its starting to be truth more than legend. And showing proof that they have stock cars.
I know the forum your talking about I think and here are some time slips from one of those 10 second cars..look at the had writing on the top of the first one.



With Drag radials..



They are fast cars..and worthy of the title of a supercar..:D

On a side note..the new ZR1..its only a few ticks faster than the Z06...and its got 650HP?? Kinda wondering whos not telling the right HP numbers. I am betting the Z06!

[guitarded]

those are the time slips I saw.....and yeah, I know the zr1's are a few ticks faster than the zo6. The numbers definitly don't jive, and it sounds like the horsepower wars from the 60's and early 70's where chrysler had claimed 425hp from the 426 hemi's,....but in reality they were pushing over 600.

On a chassis dyno, 500 crank horsepower equals to roughly 440 rwhp because of drivetrain losses. If they're making a lot more than that right from the dealership, then we know gm pulled a fast one:)

All things aside. I did visit a corvette forum, and the bulk of the completely stock z06's were hitting between 11.7 -12.2 in the quarter. It is hard to prove a car is bone stock, unless they dissassemble the motor, check the tuning, and look for well hidden nitrous. These are games played in nascar.
Did you know, that there were race teams hiding nitrous inside the frames of their cars? cheeky bastards

[guitarded]

oh yeah....the zr1 is rated at 620 hp, not 650. I remember when they first introduced it, the power figures were estimated at 650, and now derated to 620........I guess they're playing tricks again :D

[Z28 Autobot]

Yea..its not the true HP numbers I would expect. GM's fudging the numbers for some reason.
But my Uncle is a corvette guy hes got an off the showroom floor 63 split window Stingray. Cars just stopped in time immaculate.
But hes the one that told me about the Z06 breaking into the 10's. And gave me the forum to go read about it. Like I said I did not beleive it either till I found out that alot of guys were running the 11's and you can have a 10 second car but you need to know how to drive it. Most people will get 12's out of the Z06..but the guy that knows his car and can launch it the right way. Hes going o knock that 1.1 second off to get the 10's.

Im still wating to see what the ZR1 really does..and on top of it the cars built to go around corners like a C6R so we will see what happens with this car :D

But yea thanks for the call man. and for now and it looks like some people can get these cars into the 10's..amazing..

[guitarded]

I don't think all the z06's are capable of 10's or low 11's.......just some factory cars that got extra punch in them.

In the 90's there were quite a few camaro's that escaped an assembly line with corvette lt1's instead of camaro lt1's :)

I saw two guys at the track with same model year camaros.......1 was faster than the other......The losing driver thought something was amiss, so they switched cars with each other.....The same car was still slower even though they switched drivers

No your right. its a machine and not all are going to be that dead on in performance. But some guys get lucky and get a true 100% perfomance car with everything working at top level. And some of them will be great drivers and can dip into the 11's with these vettes. Some people call them factory freaks or what not. GM is not sitting there saying every 200th vette gets this little extra..no..lol. But the idea that just some times it gets built with everything fitting together like a work of art..when that happens..you get 10's
The other problem with Corvette is..its a retirement car and many do not put the car to the test and drive it on weekends and its a reliving thier youth car. So who knows? If it was a Mustang or Camaro where more than a small number put the car through actual paces when they get it you might see MORE of these 11 second cars or possibley 10's from them?


In the 90's there were quite a few camaro's that escaped an assembly line with corvette lt1's instead of camaro lt1's

Urban myth. ;) I know the guy that was the brand manager for Camaro and Firebird, He is now with the 5th gen Camaro. promotting it for GM. When the LT1 was in its heyday and was the top dog in the 90's many guys were claiming that too. The only thing is internally the Vette had 4 bolt vs. the 2 bolt main in the Camaro. And the 4 bolt cars were built with different casting numbers specific for corvette and through a "witch hunt" none came from the factory with a vette 4 bolt engine.:D But the thing is the engine is exactly the same from the factory as the vette part for part except for the bolts. Now why is the vette engine rated at more HP? better management and exhaust. The corvettes were rated at 300HP to the F body's 275HP from 93-96 then 285HP for 97 Before changing over to the LS1 in 98. And the same thing goes for the LT1s that were put into the Impala SS's back then. Well two. The Impala had an Iron block vs. the vette and the F Body's aluminum blocks. But they had 260HP. It was all in the exhausting of the engine and the computer that gave you that extra HP.
BUT NOW..lol..with that said :D

I saw two guys at the track with same model year camaros.......1 was faster than the other......The losing driver thought something was amiss, so they switched cars with each other.....The same car was still slower even though they switched drivers
That is the one problem with the LT1's they were amazing motors at the time and alot of perfromance out of those engines. But they were not all built the same coupled with the ever changing transmission dynamics in the A4 automatics that made them run different times. To the Manuals that should get the same times but did not. Other thing is gearing. The F body came out of the factory with a few rear end ratios and that plays a big part in final trap speeds..and last the exhaust. from 93-97 it was changed I think 3-4 times. Thats why you got the 10HP from the 97's they changed the exhaust. But again they all ran the same around high 13's to low 14's. The reason the vette was faster was all in the car. So its a toss up when dealing with the LT1 and how or why it did what it did. But the same can be said some guys could get factory freaks that did what they were supposed to do and actually get an amazing performance car with no hangups..those were the low 13 second LT1's that when the LS1's came out could hang with the big boys.
The only other change was the LT4 in the anniverary Camaro's that produced 305 (underated) HP.
But by then the LS1 came out and that base 305HP that was claimed actually dynoed at the flywheel at 350HP or there around. And thats why the LS1 camaro would keep with the new 400HP vette. The Camaro with almost a 100HP on paper difference with more weight chassing the tail of a vette own the track??? had to be the numbers were fudged by GM. and that is for another time but yea its all paper numbers. The LT1's were factory the same and its all in management of how the engine works. :D

And last yea I have an LT1 when I first got it I would go to the track and would race similar stock LT1's and some would always beat me by a good 1/4 panel and we had the same reaction times. Some I would edge out.

[guitarded]

so basically what your saying is there was a big tolerance in tuning from the factory. That's terrible....90's mustangs had the same trouble...cobra was slower than the lx's

Man, I'd be one pissed off ZR1 owner if I got beat by a stock Z06 :D

[Z28 Autobot]

Yes in a way there was, between each Camaro and firebird. I could go on about the LT1 Fbodies and how much was changed from 93-97. Minor things that made a lot of difference to the car. It was one of those cars that you knew you had the HP. But how effectivly it put it to the ground. That made it the test.

and well the LX was always the faster Mustang...since it was the notchback and not the hatchback and no body skirt around the car like the Cobra and GT. The Cobra was nothing much in 93 really..few extra ponies I think 245?? and dressed up with all the extra GT weight..yea the LX's were faster..and personally I like the LX's much more.

and the ZR1..well in a 1/4 mile yea it will be a close race. But in a top end race or to a mile? I think the ZR1 will show its worth. Also this car is basically a race car more than the Z06. Its tuned for the track and on a road course you would see the advantage.
But till we get some tested ZR1's we really dont know what the car will do..hey maybe the ZR1 will be a little surprise in waiting. but again who knows.

[guitarded]

I hear the cobra (back then) was supposed to have some extra ponies, but dyno tests proved wrong....Ford guy I work with said there was a lawsuit over it

Yea after looking it up the 93 Cobra was only 10HP more than the GT and LX.



It is a nice car. But for what it is it really was just a dress up from the factory. 10HP is not that much. and again on the cladding on the car and the hatchback. Not so much as the GT but still more than the LX.

The same can be said for the Camaro. The SS was not faster than the Z28. Even though it was proven to have more HP. Well considering the Z28 was rated at 305 vs. the SS's 345. But dynoing at the same HP??
Alot of people in the Fbody community just chaulked it up to a sticker and stripe package with no real performance gain just the looks of an SS.

cool little thing about the 93 stangs.
