>>>I posted the formula I used, and don't forget that this is the speed over the entire distance, not top end. Anyway, 12.380 for 1/4 mile equals 49.52 for an entire mile. There are 3600 seconds in an hour, so 3600 / 49.52 equals MPH.

Going back to my high school physics (I wondered when I could use this stuff again), I think you can get an answer.

Using the formulas:
s = .5at² + V_it
V_f = V_i + at

where
s = distance
V_i = initial velocity
V_f = final velocity
a = acceleration
t = time

You get:
.25 miles = a(.5)(12.38 seconds)^2 + 0(12.38)
a = .00326 m/s²

Assuming a constant rate of acceleration (hey, this is a perfect world with no outside forces taking place during the race, right? *g*) yields:
V_f = (.00326)(12.38) = .0403588 miles/second = 145.292 miles/hour

Rox, you were hauling a**!! WOW!!
