I must be missing something. I always thought torque is a measure of [twisting] force but horsepower is a a measure of work-force over distance and time. Even a runt like me can apply 100ft.lbs. of torque to a head bolt but I sure could not rotate that torque wrench at 60rpm! I think horsepower is what accelerates the car and the discussion should be about the trade off of horsepower peaks-easier to build at high rpm at cost of very low power at lower rpm.
