i finally went to track this year in my new to me 90 stang. here are some times i rean. i ran a total of 9 times!!! POOR CAR!
Anyways, I got progressively better with 1/4 mile times as well as launches and mph. here a re a few from worst to best.

14.2
101
2.1

14.0
102
2.2

13.9

13.8

13.7
103
2.1

each take off i spun a little in first and second. more so in first. I shifted quickly from 1 through third and power shifted into 4th each time. the first slow times, i did not bring the rpm's up at all, and spun like crazy. i played with it a little and found that i could bring the rpm's up to about 2 grand and drop the clutch. those were my quickest 60' times. these are on regular street tires with less pressure in them. Now my question is! HOW CAN I GET CONSISTENTLY 13.4 TIMES AND A BEST OF 13.2?? THIS IS WHAT THE CAR HAS DONE BEFORE I BOUGHT IT. ANY THOUGHT ON LAUNCHING TECHNIQUES AND SHIFTING, AND MYTIMES? THANKS!
