Re: 1/8 to 1/4 mile =

I'm not sure what the formula is to calculate mph. It's not usually accurate because too much on the top end can effect the MPH from gearing to a head wind.

The common ET formula is 1/8 ET x 1.56 which will give you roughly 14.70.

Is that with the combo in your sig? What's your 60 ft time? If thats with the combo in your sig, that seems kind of slow.
