Clutch Slipping?

[eMsta]

I was coming back from the gym at monash yesterday, and I decided to rev it to 100km/h on the fwy ramp. But it seemed like the clutch was slipping or something. Here is what happened...the revs were climbing, the speed was not climbing...and the car was getting twitchy. Mine has only got 164rwkws, with a turbo back exhaust and pod. Surely this is not powerful enough to give wheel spin on a straight line and on a dry road (cos its never happened before). Is my clutch on the way out? Or is it just that my tyres are not tready enough?

Mind you, after that I drove carefully.

Also - is it normal for black smoke to come out when revving? Apparently there was some smoke that came out when i hit the fwy ramp (my friend was travelling behind me).

Thanks all

i think its similar to what this guy experienced...so im tending to believe that it could be my clutch..but id like any opinions.

And if so, what model of the exedy clutch would be good (bear in mind, im thinking of doing mods later this year).

i found out my clutch was slipping when full boosting in 3rd or 4th gear it would rev out like yours. i think if its slipping in 2nd then its really bad. im in the process of getting myself an exedy hd cushion button so i can still keep it daily drivable.

yeah sounds like shes shagged. go for the exedy hd cushion 8 button clutch there really good. i got one and its not to heavy not to light an the missus can still drive it. apparently they can handle up to 300rwkw

let me know how long the button clutches last with everday driving. they grip very well but I found that it wore my flywheel out as well as the disc but mostly the flywheel. I all for brass/ceramic friction materials but not for everyday driving. I'll stick to HD organic or twin plate, but thats only my opinion they get better everyday with there designs.

a good way to tell if your clutch is slipping is to get on the high/freeway at about 100ks in 4th or 5th, moderately warm and keep the throttle flat so the cars under full load then fan/feather/kick the clutch ( quickly tap it down past friction point then release) and if your revs go up( they will a little but only due to the clutch being pushed in) and with the clutch pedal all the way out continue to rise then yeah its on the way out, or take it to a workshop but it sucks to not know exactly what people mean, its good to experience it for yourself so that your learn.

crazy..thanks for the replies

i will check some more...i still got till june before i get my next service...so i will test it till then. but yeah, that day it was just acting wierd - either there was no traction or its likely that the clutch is flocked

hey there,

after a drive do you smell anything burning? if you do, it could be clutch burn.

a few months ago my clutch started to slip in 4th, but the longer it went on, it started to slip in 3rd...2nd then finally it was starting to slip in 1st. once its gets to 1st gear, the clutch is on its last legs.

i think if you can? take ur car to the clutch specialists in your state, and ask them to check your clutch for u. it really shouldnt cost you anything. got my clutch changed with a xtreme heavy duty cushion button. they are 25% heavier than stock. they are grippy and require an "on or off" engagement. not too bad for street driven cars.

cheers

Clutch slip is fairly easy to diagnose against wheelspin, with clutch slip the car will go practically nowhere (you won't feel any acceleration), whereas wheelspin you'll still be generally accelerating.

A lot of black smoke out the back will be clutch dust. You can usually smell it too if you did a good job. Time for a new clutch if it keeps happening. They usually get worse with time, so see how you go, and if it gets worse then its time for a better clutch.

I replaced my clutch with a heavy duty button clutch. NOT fun to drive everyday and it lasted at least 40k but same problem is happening to me right now. So I'll have to take mine in and I'm planning on getting a standard clutch

easy.... put it in 5th at about 50kmh, put your foot down and you'll soon see if its slipping.

Same as everyone else my clutch slipped in 2nd whilst trying to overtake a truck. Scared the pants off me. Burnt clutch smell took a week to go away after I had an exedy HD clutch put in. I regret going HD... daily driving it was too heavy in stop start traffic.
