Heavy Duty Organic Clutch Kit (240rwkw) < Who Has These?

[Finny]

Hi all,

I just got a friend to come and take my car for a spin after I finished fitting my new turbo (KKR560).

Any way I have the "Heavy Duty Organic clutch kit (240rwkw), $335" clutch which I fitted not so long ago and going up a hill we had wheel spin in 1st, 2nd, 3rd and 4th :S 1st,2nd and 3rd were definatly wheel spin as the back end was lively but 4th was more, hit 5000rpm then tacho bounced to ~7000rpm and then slowly moved back to ~5500rpm. So it was either wheel spin or clutch slipping. I unfortunatly don't have my licence so I really can't test it out to get further info.

I am lazy and haven't dynod my car yet but I would have to say around 230-240RWKW with 4.4:1 diff gears. As far as tyres go I have a set of 245mm wide Bridgestone Potenzas that are in fairly good condition. But any way I didn't think 4th gear wheel spin was possible with my sort of power so I am thinking it must be the clutch slipping.

So my question is, is there any one out there who has managed to make this clutch slip and if so what power was required. Also with my gear ratios do you guys think that was wheel spin in 4th or just clutch slipping. We didn't shift hard into 4th just soft then when VCT kicked in at 5000rpm the tacho went mad. Also.... it was bone dry.

Yeah sounds like your clutch is slipping. I have the old group buy 240kw one, and am currently running 242rwkw with no slip, but thats with a near stock RB26, so the torque curve is flat.

Maybe just pull the boost back a few psi at a time until it stops slipping, then organise a tougher clutch.

only a idea but may have turned tires a bit viscous with spinning 3 gears and when hit 4th was enough slipping on the tires to get them to spin for a little bit then got sticky again? also, i hope you had your car re tuned after fitting your new turbo if you are giving it a flogging, otherwise you will be up for more than a clutch

Jump in your car, start car, engage handbrake, place car in second gear, attempt to move off while keeping handbrake engaged, if car stalls clutch is good, if car doesn't stall and car goes nowhere clutch is stuffed. Simple yet effective test.

I took my car out for a sneeky run and it was wheel spin. Also no it wasn't from changing 3rd to 4th. I changed early into 4th.. like 2000rpm then put the foot down and waited till about 5500rpm and one wheel light up a bit then the other wheel started to spin then it grabbed traction.

Also Muz, the clutch is new I know there is nothing wrong with it I just want to know if I am making too much power for it. Sure your answer will tell me if the clutch is worn out but not if I have too much power for it.

I am running no boost controller so stock KKR560 actuator which is about 16psi in 4th and 5th as KKRs don't have a big enough internal gate to hold 10psi on a car like mine.

I get about 14psi in 1st, 2nd, 3rd and about 16psi in 4th and 5th but its a hell of a lot better than my old turbo (early KKR480) which I saw 28psi on stock actuator.
