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.
Sorry I didnt respond more timely.
I had a Vortech Supercharger, plus AAM hiflow cats, and of course a uprev retune on the dyno.
Did not bother with intake or catback.
The mild pulley gave me 370-380 whp and the smaller puller gave me 411whp.
With the smaller pulley I could tell my clutch was past its capability but it held up fine with the milder pulley.
Later got a Nismo clutch and all was well even at 411whp (which I figure was probably 470-475 crank hp )
I staid with the stock fuel system and started running out of fuel at higher rpms so brought down the redline with the uprev for engine safety.
