New Best on Friday Night!

Took the dart to the track Friday night. I didn't know it was import night until I got there :violent1: I thought, Oh well I'll make a couple passes anyway. First pass off the trailer was a new best of 7.83 in the 1/8th at 85.70 MPH. I went back to my trailer and changed my stock 750 DP jets from 71/80 to 73/82 thinking I would jet up until it slowed down.

Problem is by the time I got back in line all these high school kids in there manual transmission imports were smoking their street tires off the line. So the second pass with the new jets I blew the tires off. No traction. Played with the tire pressure and made a 3rd pass..... again no traction.

Question: I'm trying to figure out if my jet change did any good. The MPH was exactly the same on my second pass when spinning. How does spinning through first affect MPH? I think I spun because of all the street tire rubber balls at the start line. Any help is appreciated. All and all it was a good night because I didn't break anything and got home safe.
