Suggestions for a clutch to hold 500 HP
OK, I've sent my block off to be sleeved. I'll be installing 9:1 Ross pistons and Paulter rods. Looking for about 500 HP at 20 - 25 psi of boost. I know there are a few of you out there running high HP turbo's. My question is, what clutch, PP to use to hold the power? I was thinking about the Exedy carbon clutch, but I'm not sure that has enough holding power. Any suggestions?

RPS will custom build one of their carbon clutches for you for about $3000. If you go this route, they will also be available to other S2000 owners after the development work is complete. they make what I consider hands down the most streetable high hp clutches.

i would also recommend you take a look at SPEC, their clutches are bad ass, few of my friends have them in diff cars, they work nice. also, i have a clutch specialties clutch, in my 04, its sweet, and brian can build you a custom clutch for any application. so give him a call, and speak with brian or dave. search em on the net, the phone number is on the front page.

Wow, that's cool when I get referenced by first name.
Anyways, SPEC is good, I use their clutch now with around 650 flywheel, 320 ft lbs of torque, and a Spoon flywheel. I will be switching to iron clutch disk from Compeitition Clutch(.com) with a Fidanza 8lb flywheel.
I don't recommend a lightened flywheel, and I have no idea why I am doing it again, but with a 'puck style' clutch, it's difficult to drive because the engagement is sudden. I have frequently done little burn outs at a stop sign when I haven't driven the car for a while..
I am putting the iron clutch in when I install my new motor which should be in about 2 months or so. In theory it is supposed to have a smoother engagement and better holding power when it's engaged.
Also Competition Clutch's pressure plate is 2400 lbs clamping force, and stock is 1800 (I believe). SPEC claims a 30% increase in clamping pressure which puts it at approx 2340 lbs. The owner of Competition seemed to challenge their clamping force number. Both SPEC and Competition claim to be able to produce 80% over stock pressure plates, but there is a concern of the Clutch master/slave being able to handle it.
I am looking to produce around 850-900 flywheel horsepower, and I believe that the 30% increase pressure plate + 6 puck iron disk will work, mainly because the torque level will only be around 500 ft lbs or so. If it slips, then I will have to go with a 4 puck, or some sort of custom pressure plate work. (It's possible to get iterations in pressure increases between 30% and 80% , but it requires more R&D work)
I spoke with SPEC before I spoke with Competition and they recommended a 6 puck carbon clutch disk over my 4 puck which I am running now. The focus of my conversation with them was drivability over holding power however. They mentioned that they have made street disks hold over 1000 horsepower with the 80% increase pressure plate. It requires more pedal effort however, which they said they could tweak even so it's not THAT bad. They did not mention any problems with the clutch master/slave. Lastly he believed that the 6 puck carbon with 30% increase pressure plate would hold similar power numbers, however they only claim it will hold 500 rear wheel......
I think that's pretty much more core dump on clutches lately.
