your formula might work for your car but it will not work as a rule, or even a rule of thumb. For example, I was at the drag strip 2 months ago and made a pass with a CSX with a side oiler, we were dead even up to the eighth but by the end of the quarter, he got maybe 5-6 car lengths in front of me. My time in the quarter was 12.8 and he was 12.3, my speed was 110, his was 121. The gist of this is that the computation is non linear, meaning that acceleration is not a straight line, it's a curve. So, your formula, if it were to be used as a rule of thumb, would be accurate within maybe +/- a full second, but that 1 second translates to as much as 20 mph, which would be like comparing a 1987 stock mustang gt to a stroked 392 cobra replica, just not close enough to make a meaninful estimate. I'll bet though that there is a software program that can estimate performance given the facts about the engine, transmission, hp/tq and weight, but the only way to know is to go and race, it's way more fun to do it the old fashioned way! jelous that I couldn't make it to the fling!
