I run the STS with light flywheel and 6 puck clutch....thinking of going with 3.9 (I track alot and AutoX more). Anybody have first hand pro's and con's to report?

 

Nobody????

 

I have heard it might not be the best for a turbo car. Maybe go with a 3.7 I guess if you have PLENTY of traction maybe but the powerband in your car is pretty big.

 

Kinda my thought too...just wanted an opinion of anyone driving this set-up.
Thanks for the reply

 

I can't give you names but there are a few people running them with FI.

 

Its a torque multiplier. Works best with low peak torque FI applications. Without knowing your power curve can't even begin to give you solid advice.

 

I think some folks with SC have run shorter gears, but for turbo - no way.

 

I made the mistake of going with 3.9 gears on my car and I dont have outragous HP only 450hp/400tq and 1st gear is isnt evan their....max rev instantly. I launch in 2nd gear and traction probles at the top of that...so do yourself a favor and dont do it!!!!!!!!
