For fun facts. I found a claculator to calculate how much HP is needed for different speeds. I don't think this is very accurate, but it gives you an idea of how much horespower is increased for every jump.
Coefficient of Drag: = .29
Frontal area (sq. ft.): = 15.79
Total weight = approx 3500 pounds with driver and fuel

200 mph = 282 HP
250 mph = 543 HP
300 mph = 934 HP
350 mph = 1484 HP
400 mph = 2221 HP
Mach 1 = 13,432 HP :eek:
Mach II = 165,972,818 HP :rofl:
