Just wondering if 104.5 -105mph traps are good enough for low 13's? I see a lot of people trap that with simular 60's as i had but they get in the low 13's. I hit 13.71 at 104.3 with a 60' of 2.188.

 

60 foot still seems a little high. Try to get a 2.0 and you should be there.

 

Depends on the trrack, the weather, the altitude, the car, the driver.... I was running 13.5's at 100-101. I dipped into the 12.9's at 105..... Each situation is different. You need to work on launching more efficiently.

 

See sig.
