HP = weight x (velocity/234)cubed. The Dyno is Static.

Thanks for the post on that. I don't know where the Tech guy got the .8
I bought it though.
The Tech guy probably didn't have to take a lot of physics for his engineering degree

Edit: I use that equation you posted for my hp/weight based trap speed calculators...incredibly accurate, neat math trick used in it to factor in drag. I was able to confirm this when it actually calculated the top speed of the Bugatti Veyron SS within about 1mph based on the stock ones stats (since drag & frontal area would be very close).
