Well i da the track wed night and knew on thursday there was going to be some -DA so i decided to go with 93 octane for my P/B. The humidty was hi so that means a possiblity of a slick track. I ask the water guy to not water my lane as i was the 1st to make a pass and he said ok and that was the fastest pass of the night. Runs 3&4 is where the humidity came in and the track got slippery and every 1 started to spin off the line and you can see the later it got the lower the 60' times. Heres the runs. My old P/B with 93 octane was [email protected]@+557 ft on my last time out. RUN 1 DA.....+12 FT 60'.......1.732 P/B Even here i felt the tires slip a little and same on run 2. 330'.....5.100 P/B 1/8......7.956 P/B MPH.....85.70 RUN 2 DA.....-23 FT 60'......1.745 330'....5.126 1/8.....7.987 MPH....85.63 RUN 3 Heres where the humidity came in as i started to run slower even with -DA DA.....-156 FT 60'.......1.789 damp track / spun 67% humidity 330'.....5.163 1/8......8.018 MPH.....85.91 P/B RUN 4 DA.....-235 FT 60'......1.772 damp track / spun 69% humidity 330'.....5.164 1/8......8.032 MPH....85.39
