just a thought

One thing that always puzzled me, and that is.....why doesn't the use of ram air on the intake of an engine produce more power? It always seemed to me that over 100 MPH, the force of the air would add an amazing amount of power, but that doesn't seem to be the case.

The shock wave that is created when the air hits the front end of the car causes it to displace upward and keeps the beneficial ram air much higher than most ram air scoops can grab. The higher the vehicle speed, the further distance from the hood surface the ram air is displaced. The theory works really well for aircraft, but they still like to use turbos or superchargers for best results.

You can take advantage of the little bit of compressed air forced into a hood scoop if you make it tall enough to grab the good air at higher speeds.
