stage 2 clutch power rating.

[turbo boy]

Hi guys, as a lot of you will know i rebuilt the rex last year and decided to replace the clutch as i was gonna up the power anyway. Does anyone know the torque and power rating of a stage2 exedy clutch? I think standard rex`s are good for 400hp tops. Mine is around 330ish (not been dynod yet), but i do wanna go single after i get bored with the twins.
