I have a 05 GT and I was wondering whats the max whp that the stock clutch can handle and also how much whp can stock internals handle.

 

I think the general consensus has been 400 ft/lb of torque for the clutch and 430 rwhp for the engine. Ofcourse it will handle more but durabilty is drastically less the higher you go and the more you "abuse it".
When you climb too much over these numbers it becomes more a matter of when than "if". There are ppl making more and some are getting away with it, but many are seeing serious problems over these levels. And dont forget tuning is everything!!!

 

So is driving conditions such as stop and go traffic, stop signs and lights too AND, how you come off the clutch.
