crazy turbo question

[GasSavers_BEEF]

first of all, I know they are crap but I was wondering, the electric turbo. will this work as a low level turbo for gas mileage. and yes I realize that it is just an electric fan on your intake. I have a V8 truck and at high rpms, it actually requires a larger volume of air than the little fans can put out so it actually acts as a restriction.

I was wondring on these small 4 cyl motors at low rpms, would it create enough boost or pressure to out weigh the electric draw on the battery or alternator to actually make better mpg?

this was just a random thought that I had and I ask because I don't know. I am not promoting these things as they claim that you get unbelievable gains in hp and tq which I know is crap. but what about the mpg side of it. If this idea is way out in left field then please let me know but if it is viable or if someone has actually done it and had good results then I would like to know that too.
