RE: Electric Super Charger. IS IT worth the money?

[Night Shadow <soltwede@ucsub.colorado.edu>]

I have been doing some research on these electric supers and there are a
couple available. The most advanced is also the one least likely to
produce any gains, as the electric motors are basically large PC cooling
fans (also referred to as squirrel cage fans).  This product is called the
Turbo Zet, and runs continuiously, it has a air pressure sensor and air
flow meter built in as well as a temperature sensor.  Based off these
readings it spins the fans from 6,000 RPM to 80,000 RPM.  They make alot
of claims (some VERY inflated) no real dyno charts to prove it though.

Next is the e-RAM sold at www.electricsupercharger.com

This is, and I had my bro-in law check the site to confirm this.  It is a
eletric ducted fan from a model airplane.  These units DO flow a buttload
of air for thier size.  This unit is the least advanced, as it is an
ON/OFF unit based off a full throttle switch.  But, their claims are in %
at the wheels, with quite a few dyno charts to prove it, plus they back up
thier claims with a guarantee.  They also sell a dual fan unit, with gains
in the 6-10% AT THE WHEELS.  For power to money ratio, not that bad of a
choice if you have already done exhaust/intake/cams work. Unit draws
50amps for short periods of time

Lastly is a true supercharger, driven electricly.

This is made by TurboDyne, has a turbo-looking housing driven by an
electric motor.  It draws alot of power and STARTS at $1500 for a kit.
This one probably has the most potential for real HP gains, especially
with electronic control.

After all of this, I have been looking at the e-RAM, specifically their
dual fan unit, and I have been trying to come up with a way to allow this
unit to run consistantly, based off of a vacuume switch possibly, and to
vary it's rpm by load.  Shit, a 10% gain at the wheels would kick butt,
even if it is only at WOT.
