Actually, I would look into this. An electric charger is plausible and
quite doable, but there is more to it than this. A buddy of mine and I
rolled this idea around a few years ago. You could conceivably do this with
a 3-5hp model airplane engine and a bit of work. You'll also need to make
sure you're charging properly etc. (I mean alternator and such....not the
Anyway, not impossible.

It's not a bad idea, but... It's a 300cfm blower, though. At WOT how much is
your engine pulling? 650? 700? It will drag on the air coming into the
engine and it isn't designed for significant air pressure increase even if was
trying to flow more than the engine was drawing so no real help there in any
The Vampire, "Muffin Man"
Its a complete scam. That is an engine compartment exhaust fan for boats.
No matter what the cfm it flows, it couldnt possibly provide what is needed
for performance PRESSURE! That is not a pressure pump, just a cheesy
exhaust fan. Antother thing to consider is the fact that its a private
auction, Scam auctions are private so people cant contact the buyer/seller
and let them know its borderline illegal to sell an exhaust fan as a
THAT is NOT anything but a Fasco induction blower, used in HVAC
If you look at the larger pic, you can make out FASCO on the tab...
The skinny white label, that has the black surround around white
letters..LOL..that says FASCO.
Its an induction blower for a furnace guys...
and 300CFM?? MAYBE on a good day.
If no one's mentioned it already, Thomas Knight Turbos in Florida is
working on a true electric supercharger. Says it will revolutionize
that part of the industry. But, I dunno. You can read about it on
their website which I can't think of at the moment but I'm sure google
"Horsepower is a meaningless number (except to idiots that don't know
"Horsepower and torque cross at 5252RPM. Any horsepower after that is
simply wasted work." -- Devils944
Hmm... Motor geared to spin the buisness end of a turbo at speed? Put it
anywhere, don't need as much intercooler, computer controlled boost with no
waste. I always did think it was a hell of an idea. It just needs someone to
make it work...
Actually, I put that there because Devils944 is a moron. Torque is
nothing without rpm, which equals horsepower. And if horsepower above
5252 is wasted work, then there would be no reason to rev to 7, 8, 9, or
even 18,000 rpm. There's nothing magical about 5252. If an engine
makes more power revving to 15k, then that's what you rev it to. He
just likes to argue that a "torquey" 150hp 944 can beat just about any
non-Porsche because it's, well, a Porsche. He and some of his buddies
have also questioned that a Chevy V8 can really make 600hp, so there you
quote: "This works similar to the popular gas saving tornado also it can
give you up to 8 more miles per galon even when its not on.."
I repeat, it's crap.

A buddy of mine in college who was kind of a engineering techno-weenie
gearhead type tried fashioning and hooking up an electric blower to an
old 4-cyl VW Jetta beater just to see if he could make it work. It DID
work. Sort of.
As I can recall, he had to modify a small motor (with an
impeller/fan/blower head) using a variable resistor (or something) so
the blower's CFPM output could change according to the engine's speed.
He then designed a simple small IC-circuit controller thing that
raised or lowered the blower's speed according to engine RPM, there
were sensors attached to it. He placed this assembly in an air intake
tube and stuck it between the head of the air intake and the throttle
When the thing was switched off, the air just moved normally, past the
blower assembly, through the tube, to the engine, like usual.
When activated, it kinda acted like a very, very tired out-of-tune
turbo. The thing would produce a little bit of kick, but, it sort of
stutter-stepped it's way up to WOT, not very smooth at all cuz the
motor computer had a hard time keeping up with the signals it was
receiving from the engine's RPM sensor, and when you'd lift off the
throttle, it took a second or two for the motor to wind down... you'd
have to keep sticking the clutch in or the damned thing would just
still lurch ahead on you.
An interesting experiment, but in a nutshell, you can't have an
independent air source (turbo & superchargers are part OF engines)
feeding your engine and expect it to function smoothly. Electric
motors that can change their RPM both up and down as quickly as a
conventional engine can and work in concert with it are hard to come
by - do they even exist at all?
So, it CAN work. But it looks as though the right engineering just
isn't there yet.
