So I had my car dyno tuned last Tuesday and they found over 80 ftlbs of torque and more than 60 HP with revised tuning and fuel curve. So that's good right? Well it was until yesterday when I took the car out for a little 'fun' and 'drove through the clutch'. I have a Ram HD clutch in the car now that was fine for 350 ftlbs but now with well over 400 ftlbs it's just not cutting it. Even though I can still drive the car the clutch lining is fried as it stinks every time you slip it at all.

I really liked the pedal pressure of the RAM clutch and its driveability but I need to upgrade. Can I get a clutch (driven) disc that has a higher friction coefficient that will give me more torque capacity with the same pressure plate? If not what's a good street clutch that will take 450 - 500 ftlbs of torque at the flywheel?
