Clutch held fine but started to slip after I got to 400 whp.
Dope! Thanks for that input.
What mods did you do to get to/over 400 HP, if you don't mind me asking? I have a G35 manual now. I plan to get a used engine from PickAPart, and rebuild it. I would like to build it stronger, then add boost. Probably twin turbo. The only thing I am thinking about adding to the new(er) engine is the G37 HR valve springs which I hear will support higher revving.
