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



There is no 1/4 mile tracks around here. I was running a untuned 950 carb on it when I ran those ET's. I have put the 1050 Dom. on it that it was dynoed with (662 hp)and went to track one time and it would not do nothing but spin really bad (6.80's). I have never had traction problems before so maybe I will get to track 1 more time before end of season and get a new best.

1.33 60 ft,6.21 at 110.59 in the 1/8, pump gas small block,2950lbs,drag radials,mufflers and driven to track ...
