The UPR tensioner idler pulley you sold me seems to have worked. Went out to PIR Saturday night and ran till they closed due to rain. Got 7 runs in and that is with a Predator tuning change. There were only about 8 cars running....
My best was a 12.6 @ 113 mph with a 2.1 60' time. Track was cold, tires would get wet, and they didn't lay any VHT, so launches were crap and ET's showed accordingly. I was only looking for mph this time though. OMG, I sound like a Supra owner.......
Last couple times out all I could get was 110 mph so I figured the non slip pulley was slipping at the top end. Looks like I was right. It may have also wore down the belt and probably does not grip as well as possible. I will put the Lightning pulley or consider going to a 2.8 or lower.....
