What clutch (non street twin) to support 500 rwhp??

I'm thinking a star stage 3 carbon or kelvar would work. Do I have any other choices?? I already have the SPEC pressure plate, I just need to order the disc.

I have heard pretty good things concerning the RPS clutch. It seems Star clutches are great for some and horrible for others. I have seen at least 3 Star clutches fail prematurely.

Not alot of people are willing to spend a grand on a clutch. I agree 100% that he should be getting a McLeod Street Twin but I was giving him alternatives.

Exactly... I don't think 1000+ for a clutch is justifiable. All I need is a Spec Disc to throw in my car. Whcih series is most streetable but will stil hold?

I had an RPS "turbo" clutch on about 480 HP. Lasted about 1000 miles.

I know it is a lot for a clutch, but honestly when you get to 500+ rwhp I really do not think there is any alternative.

Of course you could do what I did and that is waste a bunch of money TRYING to find a cheaper alternative and failing and end up spending the $800 anyway. Food for thought.

Exactly! I was going to get the rps 3 years ago when I had a blower making 410rwhp. Good thing they were on back order for months. I ended up getting in on a gp for the street-twin. Since the power never stops you better just bite the bullet and save money now then spend more in the future, just like 97TA said.

I agree 100% because I went through the same thing when I bought my Centercrap.

I also agree that if you haven't spend the money already, I would consider doing the street twin from the beginning.

To your questions - I have been using the Spec stage 3 clutch with the newly redesign six pucks and it has worked quite good. It was slipping like crazy after 1000miles on my first sets of dyno runs (seven pulls). But after that first dyno run break ins, it held up fine after that. I didn't take that to the drag to see how it holds up but it worked fine on the street. LJ always says that this clutch is not going to cut it for me at 611rwhp.

I just two weeks ago replaced that with the stage 4 unsprung disk with the new X-pad material. I have to honestly say that this thing is so much more easier to drive than the stage 3 even though there is no springs. I would actually recommend this to make sure that it will hold the power that you want (500+), to avoid having the springs pop out, and is much easier to shift than the stage 3.

From the setup that you are thinking it seems like you will get much more than 500rwhp so might as well do it right the first time.

So the centerforce makes a crappy clutch, what about RAM clutches, any value in these?

Camaro_SS/R, you said you went with the stage 4 w/o springs, is that the Spec stage 4 I assume?

Yes. I had the stage 3 (new design), then went with the stage 4 disc and kept the PP from the stage 3. No break in needed and it drove better than the broken in Stage 3. They both did not chatter for me. But I am used to driving "race" clutch.

In my Experience CF has not been bad... It did slip but I was pushing 607 to the wheels! and it slipped after 6 strong street races one after the other... I think that with better heads the CF will simply not widthstand the power...

I have an Al flywheel right now... Will I need a new flywheel with it?
