how much power can the cl-s OEM clutch hold?

heyya

I remember coming across this in a thread a while back, but I cant seem to find it.

I think there were a few folks running CT S/C on their j32's with no issues on the OEM clutch, IIRC?

does anyone remember the thread?

thanks!

Stock clutch is more than enough for holding the power the CT supercharger makes even with the high boost pulley.

Not sure of the thread but the OEM clutch has been OK for me. Definitely slips sometimes when I get on it hard during 3rd to 4th gear shifts and at times during 1st to 2nd but not often. I tend to have to slow down my 3rd to 4th gear shifts during spirited driving but you can still shift pretty quickly in doing so.
Still want to get an aftermarket clutch though. I think Rajca has the P2R disc and that's been holding up well but I think he gets slippage from time to time as well.

I disagree, my car experienced a lot of slippage from a dig and even moving at a decent rate of speed (30-40 mph/3rd & 4th gear).

This was with a high boost pulley, I can't say I slipped NA.

i dont know if its a weather related issue, but its in the high 90s here.

its really weird though, my clutch will slip one day, and it wont slip the next. im wondering if the friction material gets "rehardened" when it cools and it is good until it wears down again.

im also debating removing my check valve in my slave cylinder, but not sure if it will help.

Do the check valve removal it will make a difference.
I find that I get bad clutch slippage on my oem clutch after driving it for a few hours straight.

I recently did a little trip down to montana and did about 150 kph most of the way and anytime I shifted it was really bad, I had to be super careful to avoid it.
