I took my car to get dyno-tuned yesterday and made 310whp on 10psi. Anything over 10psi and the clutch started to slip.
The clutch kit only has 240miles total on it… Do you think not breaking in a clutch would cause it to slip? Im using OEM flywheel. Can flywheels make a clutch slip?
So the question is…
What makes a clutch slip?
I need to get eR’ done so i can take it back and get tuned for 28-30psi asap.

did you really leave the flywheel out to get rusty?

It worked before… lol
I think that may be your problem, man. The flywheel is supposed to be 100% clean and free of contaminants.
ACT recommends breaking in a 6 puck by making one long, slipping pass.
Did you grease the input shaft?

I didnt know that. Waiting to get tuned, i never got time to break in the clutch. Ive always installed rusty flywheels on all my cars. Never had a problem.
I did grease the bearings. I wonder if grease got on the clutch and now is slipping… hmmm… I did use a lot of it…haha

Justin was telling me he saw that happen before. Where grease on the input shaft flew all over the disk. You’re supposed to clean the flywheel and pressure plate contact surfaces with brake cleaner or another solvent that doesn’t leave a residue.
My clutch was doing this to me when it was new as well. I proceded to beat the crap out of it for for about 100 miles and now it is amazing. Its been holding great since.

cool. I guess imma’ have to pull the tranny out today and try to get it done/tuned before sunday.
flywheel is probably glazed over.
it could be so much diff things … i had a problem like this it was better for me to buy a new flywheel and then new clutch… then it worked real nice

you can use a scotch brite drill pad to clean the FW and pressure plate, then wipe it down with brake cleaner. The sintered pads on the clutch should be ok.
Am I right with saying the clutch and flywheel will always be “glazed” working fine or not … herd this from tranny shop when i was having problems

yes and no…yeah because you see the way it wears in (just like a brake rotor) and it kinda glazes over one could say. and no because when you see a “glazed” flywheel or PP, you’ll know what this means exactly. When its glazed it’s usually full of hot spots and just looks well, glazed.
instead of pulling it all apart, i would really just go out and beat on it. get it nice and hot, then see how it grips. i bet beating on it solves the problem.
newman, you’re right and wrong here. yes, the flywheel should be clean, but if its not, the rust just gets cleaned off the 1st time you slip the clutch anyway. think about it like brake rotors. when a car sits for awhile, the rotors look like they are rotting away. but take the car out and stomp on the brakes ONCE and they look brand new again, rust free. and its not like the rust will get stuck anywhere, it just disappears in a cloud of dust.
if you think the rust is your problem, beat on it. if you think the grease is the problem, beat on it some more, it will start gripping after about 50 miles of hard use. i had a friend drop a clutch disk in a bucket of oil once. he cleaned the living piss out of it before re-installing, but it still slipped. i told him to beat on it instead of pulling it out again, and sure enough, a week and a half later, nasty seconds and dirty thirds :tup:

I took the car out for a test drive and feels like the clutch is grabbing pretty good. Imma’ beat on it some more tonight before i take it apart.

Took the tranny out and cant figure out what the fucking problem is. Flywheel looks pretty good.
Here are a couple pics of the pressure plate and clutch
Do you see anything wrong?
