Dick,
Nice tutorials. One important question: Do you use engine hp, or rwhp? It
seems to me that you are using crank hp, so there are no allowances for
drive-train loss.
Is it really as simple as this? I thought tires, air temperature and a
zillion other things all played a role, not to mention drivers reaction
times and gear-changing times. I'm guessing that this simple equation
assumes no wheel-spin, cool air and gas temperatures, peak-hp all through
the rpm range, zero-time gear-changing, and perfect driver reaction time.
Still, as a guide it is a lot of fun to play.
As an aside one of the big scams in selling modern cars is the gearing they
use to ensure that the 2-3 gear shift occurs AFTER the car hits 60mph. This
way auto manufacturers can quote low 0-60 times which would be really hurt
if the motor hits the redline at 58mph.
