Im just curious at what Hp/torque the stock drivetrain starts to break. Im currently pushing 330awhp with a stage 2 clutch and everything seems to be holding fine. I plan on changing the turbo and fuel injectors and fuel pump and anticipate slightly more than 400awhp. Will the stock drivetrain support that?

 

Yes. Drivetrain limits are based more on driving style rather than power output. My stock clutch is holding my 400whp perfectly, even with 28k miles on it.

 

My stock clutch gave out at 6k, stock for first 5k

 

We put down 806whp and around 600 ft/lbs of torque on stock axles, transmission and transfer case. The car has an Exedy triple disc. Easily over 200 dyno pulls, 100 drag races and daily driven on the street.

The weak part on the launches with 600 ft/lbs was the rear end.

Thanks!

 

From what I see and hear the drivetrain is incredibly stout. Along the lines of the ETS post above, my tuner's personal X makes 660 whp and all he has upgraded is the clutch.
