Point taken but this was only a rough guide. And the boat doesnt really matter as it was to do with F1 cars and MotoGP bikes. Also, a motogp bike wouldnt have that much better speed as the cogs are changed for better acceleration. Even a stock CBR1000RR can beat an F1 car because of the gearing! Also, the HP of a motor doesnt really matter either, its to do with power to weight ratios, making the bike a better choice for short distance races. For the sake of this thread i would say in the long run, the F1 car would still win, although the MotoGP would be quicker off the line as the F1 car needs to generate high RPM's to make power, but damn those F1 cars can go some!
