Default Electrical Supercharger?!?!

I was bored in class the other day and I let my mind wander...
I thought, gee, why not take an inverter, hook it up to a good sized AC motor, and then attach the motor to a centrifugal supercharger housing? You could eliminate the */c lag that you would have if it was with a pulley, the motor turns on and WHOOSH! Instant psi. The only snag would be getting the boost to be proportional to the throttle. We have plenty of space in our engine bays to rig something like this up.
With this, you would have no HP draw from the engine to run it. You would probably need a bigger alternator, but Ty has us covered. It probably wouldnt work if you had a system, too much of a current draw.

Well, what do you guys think? Is it feasible? Possible Problems?

oh I forgot, you could also turn the motor off when you get up to highway speeds to get better MPG.

you can buy them off ebay,but the simple truth is that an electric motor cant reach high enough speeds to make psi,(they make like 1 psi) than at high rpms acually drag the motor down cause its just a restriction in the intake.if you want to try it they are like 20 bucks on ebay ,but i wouldnt recomend it unless you have 20 bucks to waste.

Not one of these things, I am talking about a big AC motor hooked up to a centrifugal SC. Those are little DC motors, you could stop them by sticking your finger between the blades. A good sized AC motor would slice your finger right off.

Something like this:

It'* kinda a silly idea, there is no lag with a pulley, cause it'* instantaneous. Turbo'* have lag because they have to wait for the exhaust to build up to spool.

It is a great idea BUT you have to build it from the ground up. The issue is the SC or CSC weight or material. Once that is done the unit will work. But (another but) it will require long-term use to compete with a conventional CSC system. In a short burst it does not compete with Nitrous oxide.

All that said I say GO For It!

dude, mount a slide switch on the throttle cable. probably have to create a control circuit to get the power down on the slide... hmm.... i'll try to get my dad to draw up some circuitry. but he already thinks it won't work... but i'll tell him i just want to see how it could work. he was right behind me when we left he job site, so he should be home soon.

Well the idea is a good one but the electric motor would have to be about as big as the engine itself! I'm not on the up-and-up on the HP ratings of modern a/c motors but I know at redline (and 10psi) it takes 36hp to turn an Eaton M62, the M90 takes 44hp to turn.

ouch, that alot of hp! I was thinking about using a belt to connect the CSC to the motor, that way we could get higher rpms.
