Anthony:

You are correct in that aerodynamic drag is a sqhared function of speed. What I said is that HP is a cube root function.

Quote per Bob Putnam:

"Yup - drag goes up by the square of speed, which means HP is proportional to the cube. It takes 8 times the HP to overcome aerodynamic drag at 100 mph than at 50 mph"

I have read this many times in many publications. Look at the example I gave you. I had a '77 Mustang with a four cylinder, about 75 hp and would go 101 mph, did it many times. If you were correct, a new Corvette could go well over 200 MPH. I'm sorry, but you are wrong. Period.
