This site is a great place to find out much needed information as i used threads from it to make extra credit in chemestry... you think it will work??

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.
