your thoughts

Sorry for the late reply. I do appreciate all the reply’s. My daughter raced it 2 days. This is a base line run leaving it in drive and letting it shift on its own at 4500 rpm. 15.95 60 ft 2.44 Speed 89.1 mph With 26 inch street tires. With 28x9x15 M/T slicks same 15.94 60 ft 2.21 speed 89.3mph. I thought that being 2/10ths faster in the 60ft it would if picked up on the top end. All bone stock. 3 runs with street tires and 3 runs with slicks. Kim
Typically, changes in 60' won't affect the top end speed. For the most part, trap speed is all about how much power your motor is making, regardless of how much you spin (within reason).
