Yes, the theory is sound. The question is whether or not this particular execution of that theory is actually effective.

Cowl induction is another way of increasing the pressure of the intake air. But instead of sticking a pipe into the wind, you tap into the positive pressure bubble at the base of the windshield.

Highwaylizard: you seem to have the time and cash to try out lots of different gadgets. Maybe you could purchase a vacuum / boost gauge, and install in into your intake pipe, and record the results. If it goes hyperbaric, then you have your proof. If not, then you know you're wasting your time.
