I don't see the belt slip on the 1-2 shift or even mid 2nd gear because of his 60' and 330' times. He's actually pulling harder on those than his previous best time. If it is belt slip it seems to happen midrange and only for a split second. I also don't see traction control kicking in with mickey thompson drag radials at the 1/8th mile marker where he's slowing down, then picking back up. My traction control has only kicked in maybe once or twice with my hoosiers good or bad track conditions and that's only at launch. Once I felt a little tire spin shifting from 3rd to 4th but not enough to kick the traction control in. Just enough to put a little fear in me.

I'm sorry I can't help more on the code 3 pulley. I have never tested one. I replaced my belt at 1k miles and 4k later still looks new. The belt is going to be hot, but to accurately report if it's getting hotter than normal a heat gun reading would have to be done before and after your runs.
