The only electric blower thing that sort-of works is an electric leaf blower, you need to do some fabrication to make it fit (as well as an extra battery to power it). I've known a couple of people who did this, it sort of works for a while, but leaf blowers weren't meant to go under the Hood
of a car
One company actually made a real electric supercharger (not e-ram). this was about 3 or so years back, can't remember the company name off the top of my head; I'll have to look around for it. It was a specific automotive application, which used a supercharger housing similar to a paxton SC, but the turbine was driven by an electric motor. the company had problems with the motors burning out, as well as power supply issues (the motor had a hig-amp draw, greater than a starter motor). it retailed for around $600 or so, but techinical issues eventually led to the demise of this product. They used to advertise it on TNN during all the hot-rod shows, looked interesting, but it died all too soon.
Electric blowers are feasible, but not practical. To date, nobody has successfuly manufactured and distributed an electric blower for cars.
Okay, got more info on that old company, the product was called "SuperPac" here's some old contact info:
1320 Flynn Road Suite #402
Camarillo, CA 93012
(805) 383-6743 Fax
apparently, they were bought out by Turbodyne over their design, which is the likely reason it's no longer produced. Turbodyne claimed to be working on an electric turbo at the time (about 1998) the SuperPac for out cars would've cost about $1500
This snippet was found on the Turbodyne website:
January 21, 2000 - Turbodyne Technologies Inc. (EASDAQ:TRBD) announced today that it has paid the judgment entered in favor of Grand Tech, Inc. (formerly: Grand Technologies, Inc.) in connection with the arbitration proceeding instituted by Grand Tech, Inc. against Turbodyne Technologies Inc., Turbodyne Systems Inc. and Director Edward Halimi.
apparently there was a lawsuit, and Grand won, but what happened to the superpac? I can find no solid info on the web.
Either way, Turbodyne is apparently the distributor of this technology now, the URL that lists their products is here:http://www.turbodyne.com/technology2.html
