Hi All,

I am preparing for the track opening next Friday here in Georgia and am practicing my launching.

My car is a 2004 Z06 basically stock (just blackwing and poly bushings which lower wheel hop) running stock GoodYear F1s.

I read on this site and others that one should "slip" the clutch but I see on my practice runs on the street that dumping the clutch (just letting it go) with a 2500rpm rev gets the car moving MUCH faster than slipping it.

What is the best way to launch:

1) Slip clutch @ 2500
2) Dump clutch @ 2500
3) .....other method

Any help would be much appreciated.

ps. Please specify on how you guys "slip" the clutch...

I would Slip Not Dump... But you will hear from more qualified people I'm sure.....

Thanks for your responses. What is the difference between "dumping the clutch" and "letting it out quickly"?

A new clutch and output shaft

You might want to check with Ranger he is the resident pro at getting a stock Z06 down the track in the 11's..

I would do a full burnout and slip the clutch at 3000 rpms to start with around 18 psi. Then adjust accordingly. If you smell cluth then your doing it right.

Big difference. If you dump the clutch at 3000 you'll just spin. A small adjustment with clutch makes a big difference in how the car launches. Takes alot of practice to get it right.

I agree...
