Lets see. For the compressor to be in it's operating range it should be spinning at around 80-120K rpms. Producing boost to make, say, 300hp will require, oh, a conservative 10hp motor to turn the compressor. Have you ever seen the size of a 10hp electric motor? Do you think that motor is capable of 100+ thousand rpm? It's just the same old junk in a fancier package.

It doesn't matter how it is controlled. As Sweeney says, no way it can turn fast enough to make usable boost.

I saw a web site where a guy put one on his car and it actually reduced the performance. I have not tested this theory, but I would think a normal engine would have an air flow rate greater than the output of the electric fan. Now, it might act as a governor for the kids...

I saw a site detailing the use of these, though their designs involved a huge gearing going from the motor to the compressor and use of a much larger starter motor. I couldnt imagine them doing much.. Still even if you could get the speed and the power. its a 12v starter motor, it draws a ton of power, loads the alternator, would overheat/burn out if ran for more than just quick bursts. Interesting concept though.

that one isnt even a starter motor, didnt look at the wores, what a load of crap.

This one might actaully work. Appears to be honest as admits long recharge time required on multiple batteries to run. Definately not the most practical way to go for several reasons, but interesting concept.
