Electrical supercharging discussion
There were some good questions and thougths in the last thread, that was closed due to the usual reasons.
Here is a further discussion that is more peformance oriented and also incorporates creative intake fabrication.
by now, you should know that batteries dont die (short) at 120amp draws, alternators produce current based on voltage drop, and that ram pressure is very little, even at 160mph.
anyway, keep it light if you want to join in.

this thread is chock full of win:
but seriously, read post # 4 of the following thread.... (read all the posts)....

"Most superchargers need 50-60hp to produce energy. That would be a nice electric motor under the hood to produce 5psi of boost. It has been tried for years for the automotive industry and is a no sale."
in the other thread, we spoke over and over about the massive quantities of air that any closed system must move in order to avoid starving the engine... and for a system to be worth doing in the first place, why bother adding weight to a car, if you can't get 3 or 4 pounds of boost ?
we're not running 8 cylinders.... but, even if we're only talking 15~27 hp, that's still 10~20 kilowatts of draw.... the only place you're going to find 20 kilowatts of usable power for up to 60 seconds is inside your fuel tank... in the other thread, i had estimated an electrical discharge @ 8~12 kilowatts for a 30 pound, part-time kit that would make any kind of usable power whatsoever.....
(i'm hoping someone might chime in on what the real cfm/hp numbers are for our 4 cylinder P-cars).
