Alot of it comes down to launch which is pretty difficult to get consistant. I also didn't do a burnout and drove through the water.
I took off the difference between that 13.3 run above and my 13.6 run at the 60ft mark and I was then 0.15 off that time. At the end of the 1/4 I changed into 4th gear every single time which had me thinking maybe I should have kept it in 3rd as changing gear takes some time and could have resulted in that 0.15 difference. There you go auto boys, you can have your win this time
It would have also been nicer for the temp to be under 20 degree's as that could have made a slight difference too. I plan to go back possibly next month when its cooler and see how I go again.
Sorry to hear you only managed 3 runs, in perth we had about 100 cars that night so it wasn't too busy so I managed to pull about 15-20 runs. Once the burnout comp finished around 9:30 or so it died and I was able to do a run and jump straight back onto the strip again
