HOWEVER, I highly doubt the claim that it'll boost hp by 7-10. If doing something this simple could do that, the eggheads at BMW would have designed it that way, considering how much time they spent coming out with the N20 engine.
Those giant fans aren't just there to simulate real driving conditions. They are to COOL the engine that is being hammered through ALL of the rev ranges until they map your system. NEVER get on a dyno without air being forced into your car/motorcycle. Bad things happen!
