traction

[Deckhand]

Sup guys, I went with Allen and the crew to SAR, and my best time was 15.42 @ 91.20 MPH and a 2.39 60 foot, 6.61 330ft.

My worst time was when my tires broke loose midrange 1st gear. I ran a 18.99 at 87.04mph and a 3.13 60 foot, 9.17 330 ft.

I was wondering why my MPH on my worst run was only a few lower than the best run. I was running down the track with the 3.42 open differential and the one tire broke loose (on the worst run) then let off the gas, then flooring it again and it downshifted and then eventually crossed the finished.

The question is, is my traction sucking on the best run too? I didnt feel/hear any spinning, and the MPH on the best run is nearly the same as the 18.9 sec run. WTF?

thanks.

Your MPH is hp and will not vary much with launch or gearing .
You can lose a half-two sec in et in alot of ways, that's why us slow guys still win sometimes. Judge your HP gains in mph,your ET's are traction and torque curve.
