I don't know much about motors that turn 10000-14000 rpm but it seems to me they have to have a much wider range of useful rpm and that is one of the things makes them go faster.
Just a thought.

John, interestingly enough - it's quite the opposite. Disregarding all the launch control, traction control, anti-stall and semi-automatic transmission technology, if you simply revved a Formula 1 motor to 9000rpm and dumped the clutch, it would stall!!!!!
They make so little torque down low as a result of the engines being designed solely to work at stratospheric rpm. A Formula 1 engine program is deemed a major success if they can move their torque peak up another 200rpm. In the previous case of 853hp @ 14000rpm, if they don't increase their maximum torque, but simply move it up to 14200rpm, they've just picked up 12hp.
If this means losing 10lb/ft at 12,000rpm - who cares! That's what gearing is for! That's why they have 7 speed automatic transmissions, and have computer simulators that calculate the gear ratios required on each and every circuit to ensure that in all situations the motor stays "in the powerband". If you hear an F1 motor at 10,000rpm, you would seriously think it was doing 3,000! Wacky engines, but certainly a testament to what some of the world's best engineers can accomplish if they're given the budget to build the best automotive parts money can buy.
