>>>This is gonna sound ridiculous but I have no clue! I was so uptight about shifting when I need to shift I was too scared to look at the gages. And we got a rollbar in this car, and would you know as I was was crawling out of the 5 point & out the window my heart was pounding so fast that I didnt watch what I was doing & kicked the memory tach buttons so we didnt even get rpm :(

>>Is that total elapsed time? If so, you hit 72.6979 MPH.

>yeah that's ET for the 1/4 mile, and you number sounds about right... the hubby was laughing at me being so shook up because "you didnt even hit 90 and feel the frame shake".

Well, don't forget you're probably going faster than that at the end. That figure above is you're overall speed. FWIW - 3600 / (12.380 * 4) would be the formula.
