new clutch to give many a run for their money
I don't believe you stalled a tilton that many times. It is not possible for someone with that much experince to stall that many times!!! If you indeed stalled that many times your friends clutch is setup wrong... I had a friend who had bad engagement problems with his tilton. Two weeks later all his clutch hubs were stripped. Also did your friend have his helper spring removed? It does help a bit...

The reason I compared the two was my budget, the price of these two are within $200 of each other. The carbon/carbon tilton would be $1500 more.

The squeeks you are hearing is the nature of the cerametallic material. Have ever driven a car with racing brake pads? As with racing brake pads, there is a trade-off in heat capacity/friction coefficient and noise levels. Cerametallic materials have a high friction coefficient as is why they are quite to engage. The friction coefficient of carobn is linear (increases with temperature) and is why is has better drivability.
As far as the shifting quality... the pedal stop is most likely not set correctly in the car. If it is not set correctly, the clutch will not disengage cleanly and cause the discs to drag (the effect of the drag magnifies as RPMs increase). If the pedal went to the floor... a pedal stop is not set and the clutch is most likely being over-stoked. Tilton clutches typically disengage about 1.5"- 2" off the floor. When a clutch is over-storked, the diaphargm spring will begin to invert and start to re-engage the clutch.
Your shifting problems with the carbonetic clutch many also be related to a mis-adjusted pedal (or lack of pedal stop).

car dynoed! the clutch performed beautifully. with over 30 pulls, the car had some issues on the dyno, but none were the clutch. It managed to hold 405 whp and 368 tq on 25 psi of boost. The clutch pedal was also adjusted, and the fluid changed for a synthetic+shock proof blend.
I will be messing with hard launches via the 2 step launch control I have set to 5500 rpm. I will keep posting with results.
The car shifts much better now that it is adjusted, and I will try to learn how to shift it so I get the best performance out of it.

issues with clutch are gone...just great performance
it's official, I have over 1,000 miles on the carbonetic clutch. It has had a rough 500-1000 miles with over 30 dyno pulls from 350-450 whp and 330-400 lb of torque at each pull. no problems at all, holds great and slips just enough under a 2 step launch at 5,500 rpms.
The lock out I mentioned earlier is gone. The clutch has been adjusted and a clutch stop installed. works great! looking forward to putting more miles on it.
