Mechanical Fan.

It cost "XX" amount of HP to turn @ "XXXX" RPM. However, at what RPM does the fan start to work like a propeller on an airplane and begin pulling the vehicle forward thus helping the vehicle go in a forward motion and offsetting the HP taken to turn the fan??

Thanks :)

You could try this as an experiment next time you're at the track. With the car in neutral when the light turns green floor it and see what your mph is at the end of the 1/8th. You should be able to use an online calculator to figure out how much horsepower it took to make that mph. Be sure to video it and put it on your channel and share the link with us. ; )
