I just wanted to know if there was such a thing as an electric turbocharger
or
supercharger,an to my surprise,yes there is people toying with it. what ive
seen on the net is that they can't get the ELE power needed to power the
ELE
motor for more than 15 sec or so,but people are trying to perfect this.so
heres a cupple of iinteresting links to look at.

I've seen a lot of junk out there. The cfm at pressure is beyond most resonable 'fans' to produce.
If you had an electrical motor hooked up to a compressor (Turbo or centerifugal turbocharger compressor) it could work, given you had an energy source to drive it and a VERY hi speed motor (80krpm) The energy source is the trick. Either use batteries which would add weight and have a limited duty cycle, or a pair of high output alternators which would add weight. Then, you have to consider the efficiency of the altenators and the electrical motor and the energy required to drive the compressor.
The pros would be you could locate the unit anywhere (Not limited by a belt or chain or exhaust routing) and you could spool at idle if you wanted. The cons would be complexity and efficiency and therefore cost.
I do think that a compressed air system may be able to deliver repeatable short term boost on the cheap (For 1/4 drags), but I drive on the street where such a system could never work based on duty cycle (Boost in on the highway going fast).
Hope this helps.
I'll check out the links.

Don't forget though bud, every time energy changes phases you lose efficiency, so by switching from crank, to alternator, back to mechanical motion costs you more power than a simple crank-driven one. Also worth noting is the fact that electrical components have a tendancy to heat up and wear quicker than simple mechanical components.

That is pretty cool. Would be useful in applications where there's no room to properly mount a supercharger (As for a Turbo, I really can't see any reason why you'd want to apply voltage to it...)
