What are these rated at? Around 800 right? Im only making 613hp 629tq(On N2O) and my clutch is slipping on the dyno. It felt ok on the street when I sprayed. I didnt feel any slippage, but my tuner put it back on the dyno a few hours later and he said it was defiantly the clutch slipping. The clutch only has 4000 miles. Whats going on? Anyone else got issues with their Spec 3+ slipping?

My brother's Spec 3+ went right at 4,000 miles and he's only putting down 420ish to the wheels. Keep in mind the ratings they give are at the flywheel, not the rear wheels. Get rid of that Spec and buy a real clutch.

I can't tell when the nitrous engages, I don't feel anything. I don't feel the clutch slipping either. I had a 10lb bottle filled and it has three dyno pulls and two runs on the street and it's empty already. I think theres something wrong.

Well that sounds like a nitrous leak of some sort. Not the clutches fault.

I can maintain steady bottle pressure though and I can't hear anything leaking. I will check all connections though.

The spike is the clutch slipping.

Why do you think it is slipping? If it were the RPM's would increase without a corresponding in increase of forward motion or power to the wheels. Is this happening?

I don't feel it slipping at all, my tuner said it was slipping on the dyno. I don't know I thought it might be wheel spin on the dyno but he said no it was definitely the clutch.
I didn't install the clutch so i don't know if it was installed wrong, but I didn't beat on it for the first 1000 miles. It did chatter occasionally but thats gone away now. I have about 6K miles on it and it seems fine to me.

i checked to see if mine was slipping. i have the same power but a different clutch. i checked by driving mine on the street, it does not matter which gear it is in but i will drive at cruising speeds and then punch the gas. the rpms will go straight to redline and the car will not accelerate, then the rpms will slowly climb down and it will accelarate. i was also on the dyno and when we hit the nitrous it went straight to redline and then climbed down and then the rpms climbed normal. my pressure plate just cant clamp hard enough.
