Although this has been beaten up pretty bad, I would like to submit the following:

1) On any given Revolution of the engine there is a maximum intake of 175 cubic inches of air consumed...
2) At 60 Miles per hour, the vehicle moves at 88 feet per second, or 1056 inches per second...
3) If the opening of the Ram Air is 3 X 8, that is 24 square inches of intake potential...
4) If the vehicle is moving at 60 MPH, then the Maximum Volume air intake entering Ram Air would be 25,344 cubic inches per second...
5) If the engine RPM is at 3000 RPM, then the Maximum Volume of air drawn into the eight cylinders would be 525,000 cubic inches/minute..or
6) If the engine RPM is at 3000 RPM, then the Maximum Volume of air drawn into the eight cylinders would be 8,750 cubic inches/second.

IN CONCLUSION, it appears that the RAM AIR can submit more air to the Air Filter than the engine consumes (with due regard to vehicle speed and RPM and compressibility) As to whether there is any positive air pressure exerted upon the air filter versus engine vacuum and whether any of that positive pressure can result in a power improvement is anecdotal at best due to the inefficiencies of the Ram Air, the filter, the air box, the intake manifold and cylinder design.

However, if the vacuum of the engine can be offset by some positive pressure, then the ability to draw air into an engine quicker lends itself to assume a positive benefit.

Besides, it just looks so cool!!!
