Twin turbo stang needs a good clutch

Hello everyone,
I just finished my tt setup. However my clutch, although good before, is now slipping unconctrollably at 2500 rpm and 5 psi of boost. Could someone recommend a truly streetable (daily driven) clutch.
Thanks

I would give Spec Clutches a call. They really know their stuff and make a good product. Tell them what you are after (that its a street car, for example) and they will get you what you need.

Spec stage II. Stage 3 is too touchy, either on or off.

I use a SPEC stage 3 clutch..You cant really "slip" the clutch..But I use mine on my daily driver and have no issues with it..Just learn to drive around it. Ive never had any issues with mine slipping.

GT40X, you dont have any problems with it being really touchy? Thats what all i've heard about the stage III is being a PITA to drive on the street.

McCleod Street. Dual disc with a floater. Allows for slipping a little and holds like a mofo... Not sure about it fitting in a stock bell though. We've used these clutches in 800+ Hp Big blocks for a while with no problems.

They say what goes up must come down but I ain't reached my cruising altitude.
Take a look at what I did but can you imagine what I'm about to do.

My king cobra clutch is toast, I'm going to try a king cobra pressure plate with a centerforce disc. I'm told this is a pretty good setup to 500 hp.

I have the disc already and a slightly used KC pressure plate so I may as well try it.

I do have plans to upgrade to a spec III when the funds allow.

I have the spec stage III with the carbon pucks..Its streetable, just takes some getting used to, especially with an aluminum flywheel. I would suggest it if you need a clutch that will hold 700ft-lbs of TQ. Can be touchey with a big cam and alumiunm flywheel though...just like anything you get used to it.

Do you loose boost when the clutch slips. Mine is slipping I think. I loose boost in first and second it's getting worse. I noticed there oil on the inside of the scattershield. I wonder if that's why it's slipping. It is an iron disc can I clean it and reusee it?

just sent out for spec II clutch... that spec III sounds like more than I need... the spec II is supposed to be good up to like 520 hp, that sounds good enough for my street applications for sure. I think if I go over that I will be shopping for a new trans and rear anyway.

Just got the car back from the shop that installed my clutch... cost 250, but it saved me the headache... and that included shaving down the flywheel, which I don't even have the tools to do...soooo... I am happy with it, it is different, more springy, but I am pretty used to it already... I will not be over 520 hp for a long time...

How hard is the pedal on the SPEC stage II compared to a stock clutch? I have a ford racing clutch and the car isn't as fun to drive with the pedal being as hard as it is.
