    If you're running 1/8 mile I'd run a 4.56. If its quarter mile it'd be 4.30 for me.

    Essential to know the horsepower per pound. I would suggest you use Page 1 or Page 2 at my site. As I point out above the spreadsheet, the results are for comparative purposes only. But, that's exactly the purpose you intend.
