Gearbox/ clutch issue

[baza]

I have just got my car on the road with a new clutch in the car and now we i accelerate hard its fine till about 3500rpm then slips to about 4500 then it grips again and pulls like a train till 7500 rpm has anyone had this problem before

Pedal adjusted correctly? Enough freeplay?

Is the clutch fork movement within spec?
If you dont know search that topic in the tech section...its been discussed plenty of times.

 

[Ross Cox]

Maybe the clutch is back to front! Did you do it yourself?

[baza]

Yes I did it my self and it was put in right I know that for sure

That is no slipping clutch issue, that is called breaking traction at all 4

 

[baza]

Now that wouldn't be a problem

 

[evo-gsr]

Surely you would know the difference between it slipping and spinning??

 

[baza]

It's definitely not spinning the wheels if it was I wouldn't be complaining I would be smiling

If its clutch it will slip more in higher gear. Get it to 3500rpm in 5th gear and give it the berries (up a hill is even better workout for clutch). If the revs rise disproportionately to speed (flares) its clutch.
traction gets better in higher gear. Not many guys will loose traction at 120kph in top gear.

I had a 6puk sprung plate that slipped. Is that what you have? A 4 or 3 puk will hold better (strangely). My clutch guy said i could take off 3 puks and it would hold better.
i went back to a organic plate.

I had exeddy organic....shit clutch...fried it in less than 20 thousand ks with only a 20g turbo on 98ron

I have a 6 puck clutch now with 300kw on e85....takes a raping all day long.

 

[4piknup]

I only had 37kw. It was a wrx....but i only changed the clutch plate, kept the same pressure plate.

 

[4piknup]

Maybe 137kw. It was a td05 at 16psi

 

[evo-gsr]

Wrx + exeddy.

2 fails in one sentence.

fucked viscous...or centre diff will mimic a slipping clutch feel

 

[baza]

I have a spare of both centre diff and viscous. I replace the viscous first and see how she goes

Did you machine the steps on the flywheel? I had a fucked VCU lately and that just feels like a slipping clutch

+1 for no clutch pedal free play. Had this problem myself.
