25th, I had a Centerforce Dual Friction in a 95GT H/C/I 3 core intercooled P600B Procharger with 11 or 12 lbs. The car ran 13.30's @113MPH. It treated the stock T5 just fine, BUT....I never launched it, nor did I powershift.
The Centerforce has been fine in my Cobra too, but for some reason, it started not fully disengaging, so that's why I'm replacing it. Don't know why it started doing this, but it never ever slipped.
