So, i recently installed a begi s1 with 460cc injectors and the clutch started slipping. There is a shop around here that sells clutches and the guy said it would be good to 300lb/ft. however, after replacing the clutch it still slips at around 8 psi. Any ideas? I mean, unless it is something else. When i put it to the floor it accelerates to around 3k-4k and then the rpms shoot way up and im not going any faster. It doesnt feel like wheelspin. Could it be an adjustment issue? My flywheel looked good so i didnt have it resurfaced. The original clutch had 63k miles on it.

Thanks in advance.

do you have a fidanza flywheel??

 

stock flywheel

 

could be warped...unless you had it resurfaced when you had the new clutch installed. Did you just buy a new clutch disk or did you replace the pressure plate too?

 

i bought a new pressure plate and clutch disc. Did not have the flywheel resurfaced.

 

i've been down this road before. You fucked up.

 

Meh, I doubt it's the flywheel. Could be, but usually that will cause lots of shudder. Is engagement smooth? Try adjusting the pedal. There's a writeup on m.net.

thats ur problem

 

what kind of clutch. you said local place did it, we have a place that does it here too. if its like our place its a 4 puc and a stock pressure plate, am i on the right trac? if so, did you brake it in? be honest, because you HAVE to brake in those ceramic clutches easy or it will slip like you descirbed

 

if it was one of those, those stink to drive around in town
the break in period on those is stupid also

ask the shop, then come back to us

 

i never had a problem with the one i had, even had it re-pucked once. 500 miles is all i broke mine in for

 

my break in period included me pulling out of the driveway
revving it and doing the longest burn out
enjoying my hard work

ive done this on all the cars ive owned,
i did this with my swapped civic,
and i put thousands of miles on it


thats my idea of "breaking it in"


i honestly would suggest having ur flywheel resurfaced. and or, ask the guy at the shop , to show u the specs for the clutch, so u know hes not just bluffin

 

The clutch pedal is very easy to press down, like, easier than stock. The guy at the shop said that it was a "dual friction" and the two sides of the disc looked different. One looked like the stock one and one side was a "button" face. I asked him about break in and he said that it didnt need to be broken in.

 

hes half right. The side that looks stock (organic face) NEEDS BREAK IN. The other side was prob ceramic, what doesent need break in (for all the haters, check ACTs site, they tell you their ceramic and sintered iron clutches dont need break in.)

FYI I have a ceramic disc, took it easy for about 2 miles, and beat on it a little. Grabs perfect 7k miles later.

 

Did you remove the glazing on the flywheel?
This at least should have been done. The clutch is just another form of a brake. Just as the disks need to have the glazing removed for new pads to work best, so does the flywheel.
I don't think it is the clutch adjustment, but just to make sure- release the hydrolic fluid in the slave and pump it up again.

 

IMO, you have to break in all clutches. Maybe there's an exception, but I always break them in. That's probably your problem. I take break in seriously. If it says 500 miles, that doesn't mean 450, or 480.

The pressure plate being softer than stock is not good. That sucks. If anything, you want it stiffer for more clamping force. Did you or the shop install the clutch? When does it engage/disengage relative to the pedal? (does it grab an inch off the floor or really high, like right before you take your foot off?)

 

i installed the clutch, im not sure on the engagement/disengagement, i have somewhere to go, so i will drive the car right now and see how it is.

 

+1. some thing need a "hard break in" but a clutch is deff not one of those things.

also pedal feel has nothing to do with the plate pressure. on my probe, the comp clutch PP i had was a tad softer pedal than the stock PP i had. comp was i think 1800lbs and stock was something like 1000-1200 lbs.

 

the pp is supposed to be a 1200lb one, what is the stock one?

 

the disengagement feels very smooth and is about 1/4 of the way down
