stu I found this post:
Finally had some time to write this, and yes we are still at the shop at 1:00 am working on NSXs. We ran the ACR/Exedy Twin Plate Clutch on Doug's NSX race car during the 7 day Open Track Challenge. During those 7 days, we pounded on the clutch day after day, and also went of the track 7 times . The clutch held up perfectly fine and lived up to ACR's "claims". We are going to continue to use this clutch on our new sleeved 8.5 compression motor. We will soon find out how much horsepower it can really handle. I am very confident that it will outperform anything within its price range. The clutch in my opinion is very streetable and the pedal pressure is about stock. If I can drive it, anybody can drive it.
