thats really frustrating that the vette docs can't give you any info.. Something just does not seem right here.. If you have a 500hp stroker motor then the valvetrain has been updated/upgraded and a dyno tune would have been done. The rev limiter should have been bumped up to at least to 6500rpm with this kind of power on a normally aspirated stoked and modified Ls1 engine.. You are missing some parts of the puzzle that does not make sense with the info you have told us so far, or the info coming from the ex-owner is not correct.. We need more info on the motor.. Camshaft,valvetrain,longtube headers,intake, heads etc..These are all questions you should have asked before buying the car,, along with receipts and dyno results Also fill out you profile and it will help you out also. Talk to the ex-owner who you bought the car from.. He should have tons of documentation if he spent the $$$.. If not maybe he is full of it.. Especially at 10k miles.. Also what transmission/axle ratio do you have?? Fill out your profile so we can help you brother

Sounds familiar. Carmen did call me back but had little information to offer. I don't think they maintain any data on their customer cars. Try find the original owner and get the info from him.

Unfortunately, the first owner did not have all of the info. No doubt that the car has been professionally done in every aspect (not a hack job), and the car has been taken care of extremely well. It would have been nice to know what exact modifications were done to get to the 500HP. The Vette Drs website is not very specific. It is a manual trans, but I am not sure of the rear ratio. Previous owner had it at the track with drag tires and it pulled 11.7's. The shift light is set at 6000, but I think that is conservative, hence the original question

Something in this smells a bit fishy .... 11.7 for a car of this wieght on drag radials; making 500 RWHP is SLOW ..... Very SLOW.
You (or your tuner) can set the rev limiter anywhere you want.

If I were a betting man I would believe they do keep such files for future references and the possibility of issues that may arise. You may not be asking the right person, or better yet I think they or just blowing you off.

If it really has 500 hp then 11.7 sucks or the driver sucks.. In any case the Vette dr would have raised the rpm limiter after all the mods and a tune In fact they have to to get accurate numbers in the high range.. Something or some things just don't add up here or the previous owner is full of BS.. Probably the later. I would have asked for all receipts before i bought the car.. If the guy really did all this work then he would have no problems giving you the receipts

Car was built for the street, still gets 21 MPG on Highway
people, the specs on the C6 Z06. 550HP 11.7? in the quarter = comparable
I still tend to think that the Vette Drs do it right, but if they truly do not keep records of what they install it would be a shame. You can see basics from their website
Unfortunately, they probably have other things that pay the rent rather than go chasing paperwork. As an enthusiast it stinks.
And as far as paperwork from the first owner, it would have been even sweeter if the documention was as nice as the car

Where is the fuel cut off set to? That is going to be closer to the top end and the only way the Vette Doctors would know what would be to look up the tune, if they still have it.
They may not keep a back up of all tunes, so they may not have the information.

The C6Z is rated at 505 BHP that will equate to something like 425 RWHP, and I suspect that with a competant driver 11.3 - 11.5 is more likely on street tires. On drag radials i think 11.0 is within range.
