hp and torque....talk about heat soaked, hehheh. Although, we did stop a couple times and let it cool for 10 mins with the fans running. Strange about the clutch....it's supposed to easily handle more than the ACT organic that I have. The ACT got thru my session. I'm sure you'll get it nailed soon....good luck !! P.S.nothing wrong with the 495 @16 and 533 @18 !! Dayum !
