Again, I know turbo hondas that have ran 11's on stock clutches. It's not your hp rating that is the concern it's your torque. Most hondas just don't make enough to need a REAL clutch which is why they can get away with pos knock off clutches. Once u make any tq u will need a gd clutch. For instance , my sr20 is making 323whp/290wtq my buddies b18 is making 590whp,290wtq. He has tons more power but makes the same tq. I have had to switch to a clutch masters fx500 while he I still running a act full face.
