effect of intake air temp
this weekend went racing, same conditions as last 15.35 pass, first pass 15.38@ 88.7, intake man air temp 68 deg. outside air temp 60 deg. then they called second round and I drove the car to the staging lanes and somehow got distracted when I stopped and didn't realize that I left the car running, well 20 min later when we were ready to go out I got back in the car and realized it was running the intake temp was 118 deg, car is too god damn quiet lol. 2nd pass it went 15.82 @ 86. dropped half a second just because intake air temp.
LESSON LEARNED!!!!!! LOL
