I'm running a 30% increased organic clutch from Extreme or soemthing..

This is it here..... http://www.horsepowerinabox.com/mall/ck07.asp

With decent grip launching at 4500rpm slipping the clutch to regulate wheelspin causes the clutch to slip, when I click second the slip will cause it to rev to redline.

I guess the organic is simply fading and doing similiar to what brake pads do.

This started happening around 1 month after owning the clutch and fitting 225 50' Simex tyres with lowish tyre pressure. The Simex tyres have a really soft sidewall that makes them grip unbelievably in the dry.

It still is fine if I don't slip it and will spin second gear up no problems if I slap the gear with any tyre's other than the Simex's.

Third gear is also possible to chirp so it is decent just doesn't like to be slipped.

Joel you are a legend this is the clutch i was thinking of getting! I think you are right slipping isn't good for fibre's i've a R33 and i slip it at 2700rpm to launch and held it a bit too long at a set of lights 'the end'.

What sort of rwkw's does you car have?

Did you catch my reply in the "Still no one running LT-12's yet thread".

This is the UAS flywheel i have.

This is the UAS clutch. Your welcome to have a drive to see what you think, its pretty grabby, but after 2 years and plenty of track work it hasnt let me down.

In the R32 GTSt you can use the GTR clutch, are R33s the same. If so have you considered an original Nissan clutch.

I have a extreme extra heavy duty cusioned ceramic clutch and i could not recommend a better clutch, its 100% drivable on the street no problems at all. And it has held 235rwkw with decent tyres on the drag strip for many passes. Still looks good with over 2mm wear after about 2 years of use, if you plan on giving your car a hard time and can afford it go for it.

For me the driveability of the 5 puck Brass button is fine.....not as smooth as your standard one obviously...but no where near as bad as some of the horror stories you will no doubt hear.

It has 3200lb of clamping pressure, and clutch weight has increased, but I found it to light in standard form anyway.

Basically with the brass buttons the more buttons you have the less savage it will drive, with cushioned Button clutches being probably the best compromise and costing around $150 more than the $480 I paid.

The only time it really becomes apparent you are driving a Button clutch is really on takeoffs and on down changes, but you soon get the hang of it, i find double clutching on the downchange allows smooth changes when you just want to drive sedately :)

I have never had one wear or break :)

Clint32 is your clutch the one RPM in adelade sell that has 100% more clamp, a full face plate with a purple pressure plate.

As i now have narrowed the choice down to that one for $787

or $495 for the 6 PUC brass as PSI_GTSII has.

Sounds like clints clutch is much nicer to use than a brassi. As i test drove a RX7 turbo today with a brass PUC, it was fine dont get me wrong but once on an incline and trying to go slow it just chirped the wheels and then shuddered due to the low revs!

    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
