Launching in 2nd with a Boosted Car

Mitco39

Anyone give this a try? Since the Turbo kit 1st gear is way to short. I have a drag clutch in the car that should be able to take the abuse and I think this would lead to lower trap times. Has anyone gave it a shot? I know on a NA car you pretty much need the 1st gear to help get you started, but it seems with boost this car pulls 2nd so well (even from right around 0mph).

I know with a stock clutch you would be asking for trouble, but this one I have is pretty stout.

I think id be more worried about F*ing up my second gear than the clutch

Or you could always just short shift it. I did it all the time with my Turboed Rsx Type S. Some people like to bounce limiter till they grab some short shift while when they spin. That's what I did.

Also a set of slicks or a good DR would help with traction also if your not already using it.

Bringing this thread back.

Anyone ever try launching in second? I have been wondering about this since with my TT first gear is a joke.

lol yeah. This happened.



The clutch will not even come close to taking it. I managed to pop the clutch in second to do a few rolling burnouts but then one time the tires didnt break free. lol

Thats the Ceramic 6 Puck, I believe stage 3 year. Well I tried to break the back tires loose and instead of them breaking loose the clutch decided that it would just slip. It slipped for about a second, I let off the fuel and it was the first and only time so far that I heard my turbo surge followed by a clutch that was then welded to the flywheel.

I had to pry it off with a pry bar and get the flywheel resurfaced. Needless to say no more second gear launches for me.

Remind me what the ratio is? I just worry about messing up the SRM.

3.357

And I don't think it will, usually the problem occurs when the ratio is swapped to something much higher like 4.08.

Remind me, are you boosted? If so, how are you liking the lower FD? Does cruise control work, and how is SRM?
