What are the factory power ratings on the stock 03-04 cobra clutch, tranny and flywheel. Also, the 03-04s use the T56 transmission correct?

yes its the t-56 tranny, not sure on the exact ratings but i know a few guys getting around the 5oorwhp mark out of the stock clutches. most of them are moving to a 26 spline now due to some slipping as they reach the 550 plus mark.

Yea id agree with that. I know of one guy on the stock clutch running a whipple at 19psi. Mines holding up fine at 525whp on a mustang dyno so thats prob 550whp on a dynojet. I guess it all depends on the car and how hard you drive it. Im going to step up to a spec 3+ and 26 spline input shaft.
