Forced Induction cars seem to be happy until around 550whp, beyond which things can get a bit sketchy. As far as the rest of the driveline, the clutch is the weak link from the factory, which is fine. Once that is strengthened, the driver’s side output shaft in the differential is notoriously weak. When you have your 3.90 or 4.10’s put in, have a stronger shaft installed for another $300 or so.
