clutch for type R
Hi i have a type R v4 and have just had it mapped by Andy Forrest and am told its running around 340/350bhp torque not known, the clutch has started slipping mostly in 5th gear so im putting a new 1 in aswel as a flywheel. Can i run std clutch/flywheel at this power and will it last or is it best to uprate ifso what to. Also would it be worth putting a lightened/balanced flywheel on or best to stick to std flywheel.
Sorry for all the questions just dont know where im at with clutches.

If the clutch is gonna come out, uprate it mate! If its started to slip since its been mapped but never did before hand then thats normally an indication that its not really up to the hike in power. I know a lot of people get the pink box (stage 1??) exedy clutch and say they are very good. And I would definately change the flywheel for a lightened and balanced one whilst your at it. I spoke to David at APi about this when I had my car serviced by them last week, and they can lighten and balance you standard flywheel for £150 I think which is very good. Give them a call.

From experience:
Andy F maps are good arn't they! (he's done mine too)
The API flywheel is just great, invest in one. The Exedy clutch he sells is not the 'Ebay Special' but a solid job.
I have an AP organic in my Sti, but would not hesitate to use the API unit.

I'm running a Helix group N clutch and fidanza lightweight flywheel. The clutch is really nice, is easily coping with 350/350 and I've every expectation it will cope with 400/400 when I up the boost.
Nice clutch as well, not jerky or grabby, nice for the road.

The exedy clutches for £150 on ebay are basically standard clutches but branded as exedy. A proper stage 1 exedy clutch will cos you around double that.
I very much doubt the car will need remapping with a lightened flywheel, that basically just allows the engine to rev a lot quicker as there is not as much weight on the flywheel for the engine to turn.
Either an exedy stage 1 or the helix is gonna be a very good clutch, I've had both clutches on previous cars and I must admit that I did rate the helix a LOT more than the exedy. The helix is very light on the pedal and took every bit of power and abuse I threw at it.

Agree - helix is a nice clutch. Surprised more people don't use 'em
