you're running boost through a stock clutch?? Wow. The limitations of a stock clutch are not much higher than stock. A set of sticky tires on an otherwise stock clutch shouldn't have much of a problem blowing up the clutch. FYI, the king cobra clutch is rated 30% over stock, or around 300ish flywheel horse. If that tells you anything, you're running on borrowed time, as the stock clutch is well under 300 horse.

in my opinion? the stock clutch is ok for a stock engine.... maybe.... and nothing more. You're running boost? stay away from the stock clutch.

I think the stocker and the parts store replacements are barely sufficient for getting from A to B. Running a built engine with boost? You're well beyond it's limits and it's just a matter of time until it's dead. Take it to the track and you'll start to smell it.

I got a new stock clutch (parts store I'm sure) with the T5 conversion the guy sent me. This thing slips with my h/c/i, works ok for DDing, but if I step on it...

The only reason I'm using it because was I teaching myself how to drive a stick (yes, in a souped up Mustang) and I didnt want to burn up a good expensive clutch. Now I got the foot work down and I'll be getting a better one soon.

I ahve had the opposite. I have ran the stock clutch with a stock t-5 and MT et DRAG (1.62 60 ft) and had no problem with the stock clutch. Ran it MANY times that hard and no problems

Man you're getting real lucky. If i don't wait for my King Cobra to cool between passes it starts getting hot and i can smell it, and i'm not even on slicks.

My stock clutch doesn't seem to like 4K RPM launches.

There's nothing wrong with the factory clutch disc itself, but you definitely want a different pressure plate.

for you application, do a centerforce DF. much more clamp force and more dependable (i.e. it isn't going to fatigue and frag on you with that repeated heat cycling)

I have my stock disc sitting right beside a King Cobra and there doesn't "appear" to be any difference. They are identical. The pressure plates are way different though.
