Analyze My Timeslip

Lower tire pressure and a good bit of heat in the tires will greatly help with 60', which will lower E.T. as others have stated. Lifting early has made a big difference in trap speed, I agree that 110 to 112 mph should have been easy. 100 lbs of weight equals about .01 second in E.T. so the cooler etc wasn't a big factor, but I would never have anything in the trunk when I make a pass except the spare tire, firmly secured in the well, and I normally try to keep close to 3/4 of a tank of fuel for traction. Try 18 to 20 psi tire pressure next time and do a 5 count in your burnout before letting off the brakes. Keep getting more seat time and the improvements will come.
Good luck and beautiful car.
