Default How long will a slipping clutch last?

I just put a new act HD clutch and light weight fly wheel in my car 10,000 miles ago and it started chattering after 500 miles and now it isstarting to slip and I need to drive to great lakes IL diving it nicely should it last the 900+ mile trip?

Any suggestions on a cluch that might last longer running basic stage 4 lat time dynoed only put 256HP at 14psi to the wheels

Just don't floor it and when you're engaging the clutch make sure you hit the friction point before you give it any gas.

I have driven around for 3 months on a busted clutch. Its not the safest thing in the world but you can do it.

Well, I wouldn't drive 900 miles on a slipping clutch but, that's just me. I'm not keen on the idea of getting stranded out in the middle of nowhere in 11-20 degree weather. Make sure you carry some warm clothes in case you're forced to hoof it. I've made the trip many times. The mountains in WV and PA might be enough to kill the clutch depending on how worn it is.

Me neither. Especially considering that's almost 10% of it's life.
I would get a rental car; they are cheap.

1k miles = 10%
so 10k miles = 100% life of a clutch

there are a ton of options out there man. 10k on an ACT HD is very very low. I'd try to address the issue causing such a premature failure first.

I have an ACT HD. It seems to have worn quickly too. I put it on at the beginning of summer and took it off this winter for other reasons (engine swap). I just know that pedal application got progressively higher over that short time. I don't know if it would have failed pre-maturely or if it would have eventually steady stated. I was putting probably 50-80 ft/lbs more than stock through it though.

yes I noticed it grabbing higher and higher when first put in it would start to grab an inch or 2 from the floor and now grabs on the last inch and I think i was putting down maybe 280ft/lbs to the wheels

my old car had a slipping clutch and i ran it that way for a year. it only slipped under full load and i drove at 80% throttle most of the time, so it lasted. it just depends on how bad it is, and how you drive it. you could theoretically milk it for a long time but its no fun.

ACT, look into the flywheel also. Stage 3? What mods do you have? Going overboard on a clutch can be a bad thing.

we see way too many people go over board on clutch selection. We get calls with people asking for way to heavy of a clutch for their setup. If anyone wants specific advice for their setup, feel free to pm me. Always happy to help.

My OEM clutch started slipping around 100k miles. I'm just almost at 110k now and I'ts pretty well toast. The new one is going in next week.

Of course... my clutch has lasted as long slipping as yours has its entire life.

I'm sitting at 75k and my clutch is starting to slip. Not much at all, but its noticeable. Granted, this is probably a little early for the OEM clutch to be going, I run the car hard and I'm fairly certain the guy who had it before me did some "spirited driving" as well.

I have babied it since I felt it the first time, and will baby it until I can afford a new one.

One characteristic of the OEM clutch material is that it is somewhat recoverable after the material cools down. I don't know if the ACT clutch does this; probably not.

My OEM started to slip when accelerating in 5th gear (17 psi), then it started happening in 4th.

Then I let a Subie mechanic drive it and he said it was'nt slipping.

Then I got it to slip in 3rd gear acceleration, and I said replace it.

He said the friction material was not quite gone, but it was close. I noticed it at about 95,000 miles IIRC. I thought this was a good lifetime, since I do hardly any steady state driving.

clutch selection and proper break in are key! We typically over do the clutch choice or get a stock replacement when the car is making good power.

I'm not terribly familiar with ACT clutches as far as what material they use on them... I do know that Organic and organic/metal clutch material is quite recoverable after overheating. Kevlar is a different story... Once Kevlar is burned, it's toast. You can glaze kevlar, and then recover from that, but if you burn it, it's done.

And dose any one know of a anti roll back feature that comes on our cars? which slips the clutch or holds the breaks so we dont roll back when starting on a hill?
