New Clutch Again!

[tricstar]

here we go again.....a bit of history......had car ( r33 GTR just under 400rwhp) for three years and about to put in my fourth clutch..

first one was twin plate exedy, liked it and it drove nice but only lasted 1 year, at $2500 + labour , didn't want to do that ever year, so I asked on here and rang Jim Berry- thought he was the answer so got heavy single, installed, ran in than on the first hard change to 2nd smashed clutch and gearbox (turns out it was an r32 clutch revamped with mega clamp ) Jim sent me a new one( r33 this time)

which I put in not having $$ ( after replacing gearbox etc ) to buy another clutch.. anyway after a year of it shuddering and welding itself to the flywheel I think its shagged too.. ANYWAY please don't suggest another Jim Berry, I'm not put another one in !!!! not here to bag Jim, he's a good guy, his clutches just haven't worked for me...........

I drive it quite a bit, about 15000km a year including once a month up the track about 30-40 hard laps each time aswell as other 1 and 2 day events ( motokana type stuff ) quite abit of launching, quarter miles etc and drive almost daily....

well there is the history and requirements, can anyone from experience tell me if any of the following will stand up to that and last more than a year ( or is that just asking to much ) or at least give me your experience with them......

NPC twin -- like the sound of these,,custom made and totally rebuildable with cheap off the shelf parts......?? @ $2200

Nismo coppermix -- read some good reveiws but how long do they last and are they rebuildable ?? $?

OS Giken -- don't know much but pricey and are they all push ( don't really want to change to a push type )

anything else I should be considering ??

Yes these are rebuilable no probs with the plates only and a machine

Read the Twin Plate thread so far so good that the clutch is almost a 10 out of ten

has some weirds things like Lots of Running in etc

PM me and ill tell you more

What are you doing to destroy 3 clutches in as many years?

after destroying a extremme clutch in less than 6months and having them flat out saying NO to replacing it under warranty i went and looked for a Japanese brand clutch. Went with the Nismo Twin Plate (rated at 600PS, you can get a comp. one which is rated at over 800PS) costed me 1.6K landed. Very nice clutch very easy to drive none of the typical twin plate rattle. Hope powers perfectly and its not to heavy that it will destroy your gearbox.

Also the clutch can be repair (nismo sell the repair kits) and it comes with a chrome-molly flywheel.

I have had mine for 2years now running 400HP

wouldn't use anything else

Also who is installing your clutches? as poor install can results in damage to the clutch?

only one destroyed , hard to say what went first clutch or gearbox, the others have just worn out------do fare bit of track work, events ( lots of launching out of the box ) 1/4 mile runs ( more launching ) and just general driving.. was told my old exedy twin just wore out due to driving in traffic..

as for install, first three done at reputable workshops , last one by me

Well, in my 30+ years of driving, including a lot of motorsport, I've never broken a clutch. And only ever replaced a clutch maybe 2 times, and only then because it seemed like a good idea at the time (gearbox out).

I've been running an exedy sports tuff performance clutch for 5 years now 64 runs at the drags,an a couple of track days plus heaps of hard cruising,no prob works beautiful.

remember he is running a gtr with 400hp, the clutch will take alot more

Hmmm sounds like you'd need a very strong cluctch to handle that kind of power.

Not really, considering the GTR is RWD until the rears start to light up.

Hence if he's breaking shit, he should be smashing pressure plates apart, not wearing a clutch out.

By the time ATTESSA kicks in to make it AWD, the clutch should be fully engaged, if it's not, then it's purely driver error by most likely too many revs, and too much clutch out quickly.

yeah not sure about that......... the ATTESSA is allways primed and doesn't wait until the rears lose traction, it's also controlled by the G sensor so the second the car moves from a stand still the fronts are ingaged ( to the max if your launching ) so as soon as you start coming off the clutch the front torque split gauge goes straight up.... so I would say there is a lot more stress and wear on the clutch in a GTR than a RWD car..

anyway thats my understanding..........
