electric supercharger
has any one ever heard of an electric super charger here are the details:Electric Supercharger kit for all years/models of Subaru. Unlike typical superchargers that get power from engine belts and can easily damage and blow cylinders, the Electric Supercharger gets its power from the vacuum inside the throttle body as well as the 12 V power supply from your car battery. Spinning at 150 CFM at 8000 RPM. And using the activation switch included in the kit, you will be able to turn on your boost at open throttle for an instant kick. This will allow you to control your boost without having to purchase a $300 boost controller or timer. The supercharger will ram air into the throttle body and significantly boost horsepower and torque. This is by far the best electric supercharger on the market for your money, as well as the safest, most reliable, and durable. Will elongate intake tube by about 4 inches. Fits in between a 3 inch wide intake tube and filter. Kit comes COMPLETE with everything you could possibly need - all installatio! n and mounting hardware and wiring and complete, easy-to-follow instructions
hey thanks

Actually there are electric assist turbochargers under development:
There is an electric motor/generator on the turbo shaft of the turbocharger that is used to spin it at low engine rpm's. It is supposed to eliminate turbo lag. Pb is it requires a lot of juice. This is solved with bigger batteries and a motor/generator that control maximum boost by braking the turbo and generating electricity.
Still experimental, though.
If you want I can try to find some articles on it.

If Johnny Rocks had mentioned one of these, we probably woulda been like "ooooh neat idea"

Why an Electric Supercharger Will NOT work
You could create an electric supercharger.
but why?
An electric supercharger claims advantage over a traditional suypercharger due to the fact that it does not run on a belt drawing power from your car. Instead it runs on electricity.
One Question:From where does it get its electricity?
Answer:Same place everything else does...the alternator...whichs runs off a belt and robs power.
So, by the time you install an alternator large enough to push a SC, you really haven't accomplished anything. Actually, you have lost since their is never 100% efficiency in energy transfer.
Sound reasonable?

battery supplies power not alternator
I assume that the electric assist for the turbo would be activated by the throttle position. At WOT and low RPMs the boost pressure on a stock WRX sucks. Therefore, if you had an electric motor to assist the turbo to spool up, any current draw would last only a short time, until the turbo revolutions are sufficient to provide desired boost. This short-term power would come from the battery. The alternator supplies a relatively constant power output and one of its main duties it to keep the battery charged, so it would not be a big player in supplying current to the electric turbo assist.
I would forsee the electric turbo assit acting like a starter motor. the starter draws a lot of current for a few seconds. The electric turbo assist would create big power draw for a little bit (say between 1000 and 3000 rpm). Depending on the gear, this would take from between 1-5 seconds - after the turbo hits 3000 or so, the electric assist turns off.
If there was such an animal it would make the WRX enging perform more like a V8.

That's exactly how it is supposed to work.
I have read too that they might use the electric motor to control over boost by slowing the turbo down by generating electricity:

By the way, what kind of animal are you?
