This are pretty rough, but how about:
HP = ((MPH/235) ^ 3 ) * Weight (lbs)

This from HP = 550 ft*lb/s, 1/4 mi distance, no tire slippage or air resistance. The cube comes from deriving acceleration -> distance.

ummm i tried to do that and on my car @117mph (the top) ands i should get 431 hp and an accord engine will do that only in it's dreams
