Car is getting slower in 1/4
Last year I managed to get a 13.19 @ 105 I made it to the track last night and I'm trapping faster now but could only manage a best of 13.53. I know DR would help but there has to be a high 12's in a car trapping 107? right
here are a couple of runs. I'll post a video in the morning
60ft 1.977
1/8 et 8.7
1/8 mph 78.68
1/4 et 13.53
1/4 mph 106.15
60ft 2.088
1/8 et 8.82
1/8 mph 81.08
1/4 et 13.55
1/4 mph 107.16

not much into drag racing but i know track temps help or hurt tire grip. that could be a big reason. plus a car will probably never run the exact same numbers twice even under the same conditions, too many variables. it might help if you posted the numbers from that 13.19 from last year.

Your two passes in the OP seem pretty consistent...even if the numbers leading up to the 1/4 aren't as close as the 1/4 numbers.
Are you shifting at the same rpms consistently? Was that 13.19 pass on a cooler day? Today most of MI wasn't exactly scorching hot but cooler temperatures can make a small difference.
