Went to the track and 1/4 et and mph don't appear to match up between the three runs or even with the 1/8 mile data from the runs.
Car is a 3.7 Mustang. Was having traction issues in first and second at the track due to the stock pirellis. I know I need a tire.

run1 (traction control off)
60ft - 2.1719
1/8 - 9.16 @ 79.35 mph
1/4 - 14.3111 @ 94.51 mph

run2 (traction control on)
60ft - 2.2238
1/8 - 9.2150 @ 79.06 mph
1/4 - 14.2799 @ 87.35 mph

run3 (traction control off)
60ft - 2.3652
1/8 - 9.5028 @ 77.98 mph
1/4 - 14.4670 @ 98.48 mph

Density Altitude: 1545 feet

Does anyone have any feedback on the runs? Not sure why run 2 had a slower 1/8 mile but a faster 1/4 miles and why the mph was so slow n run 2, or why on run 3 the car picked up so much after the 1/8.
If the car was to hook what would it theoretically run given the mph?

There are a ton of factors that will determine the times and mph, the runs will vary greatly depending on wheelspin, shift points, etc.....on street tires usually 100mph traps are a high-13 second car. Your runs look about right for a beginner driver.

looks about right to me. As stated traction will play a big factor in your mph and your numbers at the 1/8th.....
