I’m back from Milan and it wasn’t a great weekend. My 2nd Timed pass on Friday I broke a blower belt, guess I should have changed it a while ago it’s a poly chain Kevlar belt, i didn’t have a spare, I have never thrown a belt of broke one......I’m bad my fault even at 66 I’m stil learning! On a positive note it went 8.08 when I tossed the belt 7 sec into the run about 800-900 for from the starting line! Going to order 2 belts, live and learn.

Jim,
What I was hoping to do was take the numbers from the time slip and see if I was able to simulate what it would have run if the belt had no broken.

I’m thinking it might have been a 8.02, it all depends on how it was pulling top end. I did make a jet change on that pass which seems to have slowed it down in the 1/8 mile from the pass before, even though the weather was better.

Time slip on left is first pass, shutting off at 1/8 mile, slip on right is run with belt breaking about 7 sec into run (800-900').
I jetted up from 192 to 200 on second pass, looking at numbers it slowed down even though the weather got better.
Only running 11-12 lbs of boost.

George,
Thanks for posting the time slips. I was not able to get anything to workout.
