I have the same problem. I have a 1.33 60 ft. and run 108 mph most of the time and ran 109 once. According to the calculator on Wallace Racing web sight I should be running 112 mph and 2.5 tenths faster.




To me it's saying you have the chassis sorted out really well, vehicle weight is light, and you are ET ing good without a bunch of horsepower probably 575- 590 horse?
Do you run a lot of gear?
Ever run it in the 1/4
