A typical box fan moves about 2000 cfm on low.....do you really think you're going to move 1/4th the air flow of a box fan with a little fan in the intake? If these things actually worked, why wouldn't the OEMs use them?
I'm betting you haven't actually measured the horsepower increase (or 6.4 second 0-60? come on....), but instead are just trying to get people to buy your product.....

I suspect also that he's got something to gain from his claims...and to his credit I have seen electric superchargers that can move so much air, they will actually "hover" 4 ft off the ground if wired up and turned loose...but they also cost MUCH more, and can only run intermittantly and then only at WOT...and any actual boost produced only offsets the parasitic load on the alternator when it has to suddenly provide 60 amps or more to the thing...the best I've seen can produce (claimed) 2.5 psi to the intake, and the increase (according to their own provided dyno charts) was only noticeable in peak HP, WOT, top of the RPM range, and even then wasn't very impressive (about 4-5 hp, if I remember right)...
