How Fast Will It Really Go???

If you use common sense equations to figure out this problem it really is not all that hard.

Say..

Power = 400hp = 300kW = 255 Rear Wheel kW ( 85% driveline efficiency)

The density of air = 1.2kg/m^3 (give or take)

Cd = 0.4

Frontal area = 2m^2

Rolling resistance = 0.014 ( Not sure but very reasonable)

Mass = 1200kg

Acceleration due to gravity = 9.81m/s^2

Top Speed after computing = 79.58 m/s

Which after converting into Miles Per Hour = 176.8 mph.

does this have any basis in reality without specific accurate info for every variable? I'd say no.

man you might open a can of worms if you bring that thread up again!!!LOL
