if it takes u a while to get to the track....(a long drive)....let the car cool off before u run it.....heat is a very bad thing for our auto's.......if u get on it all the way there and then pull right in line your tranny is hot....and doesn't like it....equals slower times.....good launchin will help u also......from what ive tested on the street.....power brakin up too 2300 or the stall speed ( i guess thats what its called) doesn't feel as fast say u rev up too 2000 or a little less......id just take out all the stuff in the trunk....run twice at the most and let if rest a min.....restin between runs will prolong the life of the tranny.....less heat:thumbsup

18.9 is the very reason i wont run at the track......signs point to slow so i ain't gonna go.......
