Help Launching car...

I have tried 5 times and everytime it's the same. I turn off PSM, rev car up to 3500 to 4000 and drop the hammer...and it bogs and then takes off. I would rev it up higher but not sure if I risk damaging anything.
I can successfully launch my buddy's S4 where it just catapults off the line but my P-Car, I can't duplicate it. Any ideas? BTW, Tubi exhaust is in now but I doubt this has any impact on the launch.

S4 = Engine Front = Wheel spin
Porsche = Engine Back = Wheel Hop

Take it easy on your clutch .. it will thank you later.

I doubt the S4 would have much wheel spin unless it is heavily modified. Most AWD cars will bog off the line because there is so much grip. If you don't want to bog, you will likely need to increase launch RPM and slip the clutch more. Probably not a good idea unless you want to change the clutch soon.

On my Evo its a 5.5k launch with LOTS of clutch slip - hard to get right w/o burning but once you do its crazy.

On the TT I would not be in a hurry to launch it, its plenty fast to where you can do a mellow 1.5-2k hurried take off then floor it. Not too hard on the car, still plenty fast to make quick work of a competitor.

Upgraded clutch and flywheel + 5500rpm clutch drop = LOTS OF FUN

AFAIK the technique isn't to rev and hold it and drop the clutch. it's to quickly release the clutch as the RPMs are still climbing. after that, it's just finding that 'sweet spot'. If it bogs, not enough power or too much clutch or both.

Basically quickly feathering off the clutch.

Very high chances of breaking axles on launches. Porsche's are very sensitive to launching, you need to really feather the clutch when you launch the 996TT. You can't just rev and drop the clutch, its asking for trouble.

Just flash it and install an exhaust, you then wont need to launch it hard to take anything down.

Ya, definately not like a rear wheel drive. You need to work the clutch.

And don't forget to put $150 into a jar every time you drop that clutch..
You can then use that money to replace your prematurely destroyed clutch..

Rear Engine = gentle release of clutch and steady increase of power.

You want to spin wheels, by a Viper.
