I'm more curious as to how the unit is designed to only run at WOT, but is 'universal' in it's application... <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

I saw a kid do this to a Civic... Interesting concept, but I doubt there's any merit to it. For one, you wouldn't have any consistency as it's not a sealed pump (like an s/c). There's no way for the fan (as that's all it is) to apply consistent air pressure. The reason why all s/c's are driven off the engine instead of a separate electric motor is to ensure a constant pressurization according to engine speed. I imagine one could set a vacuum regulator in place aft of it hooked up to a blow-off valve, but anytime you were driving around not under WOT you'd hear an annoying whistle of air. <img src="/forums/images/graemlins/lol.gif" alt="" />
