I put some drag radials on my car. I was wondering whats a safe RPM to be launching at. 3g seemed to bog so I stepped up to 4g and thats when it doesn't. I don't go to the track but maybe once every 2 or 3 months. I figured the 8.8 would hold up well to 4g launches. I just wanted to see how high everyone else is going and not breaking anything.

Just out of curiousity are you dumping the clutch or slipping it?

I'm dumping it only slipped it with street tires.

stock clutch and rear end?? what type of power are you making?

Solitear

I thought stock rear can hold a dump on slicks O.o(i know clucth wont like it)

im interested in hp numbers, 60 ft times, 1/4 mile and et
let us know please as all this helps with diagnosing how hard your actually launching

Stkjock

depends on the power the car is making

Diabolical!

Before I went whipple, I was dumping the clutch at 6K rpms on M/T street slicks. Still on the original rear end.

Yikes 6000rpm clutch dumps?? Sounds like russian roulette on a stock clutch.

well if he's dumping at 6k, its to burnout, therefore less of a strain just the inital shock load and then not so bad, less then 350 hp with a cheater slick should last more then many hard launches. I know guys 1.6 60' with stock internals and my 1.8-2.0 60' both with no issues.
but with 450~HP nope i wouldnt dump a clutch, smooth slip of the clutch is always better, unless your makin smoke.
I slip at 2500-3500, depending on tires
