Hard lauches with a soft transaxle (found on 944 variants) require excessive slipping (Press and hold brake, hold revs to about5500rpm, release clutch halfway to build some boost, release brake and gradually release clutch)
I wouldnt go with either, get a ceramic disk for hard launches.

I used to do it often. The only time anything broke is when I slammed it into second right shortly after finding traction (4 axles in 3 months)
Honestly, if you plan on racing people, it does much better on rolling starts, preferrably starting around 80mph. Less things break and you wont get embarrassed as often.
Also, if you are going to shell out $600-700 for a stockish clutch, dont get anything organic based. I'd say neither in your case.

It would depend on gearing, clutch setup and torque.

i have a cup clutch i ordered from paragon w/ a 930 disc. According to them the 930 disc is alittle wider, alittle thicker and cheaper. THis has pros and cons but has worked great in my car up to 350rwhp where it started to slip alittle. The pedal is stiffer w/ the cup pressure plate but not terrible where a real mean clutch usually has a very stiff pedal. In theory the 930 disc would last alittle longer than the cup for a cheaper price.

Scott Gomes of Under Pressure Performance http://www.area951.com/ - Good guy.
I thought the pressure plate was the same on a "turbo cup" clutch and a stock 951 clutch - the difference being the more aggressive clutch disc which is similar to the 930 disc?
Picture from Magown, Cup on left - 930 on right:

really....hm its been a couple of years since i put that clutch in but i thought it was a heavier pp. Maybe it was just heavier than my worn out stocker. So what would be the next step to hold over 400hp, the disc or a heavier pp?

I like the KEP stage I with the South Bend Feramic disc. > 600ft lbs torque capacity and good modulation, with onlyl slightly higher pedal effort. Has survived quite a few 1/4 mile runs and lots of track time and over 20,000 miles of street driving to date.
