14.7@96mph does this sound right?
I'm asking this question because my dad took his stock 95 Trans Am to the track last night and ran a 14.7@ 96mph with a 60' of 2.3 , I'm running 14.1s @ 96mph with 60' of 1.9. Why is there to much of a difference in times but not mph thanks

Rule of thumb. 0.1 seconds on the 60' time will give you 0.2 seconds on the ET. MPH is independant of ET. MPH is primarily determined by horsepower. Both cars therefore have similar HP/lb, but one of them hooks up better off the line.

If I remember right, your MPH is measured in the white painted area down by the lights. Any number of things could cause the MPH difference, from gears to tire size and so on. I don't think you can really equate time with speed. Have you ever seen a top fuel or funny car blow up and have an ET in the 7's with a speed of less than 100? Or how about the big boys breaking into the 300's and lose to a slower car (quicker ET, less speed).

Well, if I was just worried about standing starts, I would want to make all the torque I could. Horsepower will follow. Anyway here is a link to calculate your horsepower: http://www.dsm.org/tools/calchp.htm

Here is the disclaimer at the top of the page:
"NOTE! This is just an estimate, and is probably not all that accurate.
This program will give you a ballpark estimate of your horsepower. Please don't make the mistake of quoting these numbers as if they meant anything."
There is a more accurate formula, if I can find it again I will post the link. You need to put in a whole bunch of data, though. Drag coefficient, gears, etc.
Remember that HP is just a formula taken from the torque. And that is the answer to the original question. I constantly out run cars with more HP because I have 438 ft lbs of torque and good gearing 1 through 4.
