Electric Super Chargers
Electric Superchargers
are an effective way to gain a fairly substantial
amount of horsepower for a very low cost. Not only
are they inexpensive to build, they are generally easy
to install and are safe for your engine if installed
and built correctly. The Electric Supercharger
installs right onto your cars stock intake system.
When choosing your main Supercharger Blower unit, be
sure to purchase a unit with the highest amount of CFM.
Tools:
1) Assorted Screwdrivers (flathead, philips, etc.)
2) Needle Nose Pliers
3) Hammer
4) Hacksaw
5) Wire Crimps

3) (1) SPST Momentary
Push Button Switch
4) (1) Roll of
Electric Tape
5) (1) Metal Bracket

12-Gauge Wire
7) K & N or
equivalent Cone Air Filter
8) Miscellaneous
Filter Clamps
Installation Instructions:
Please note that it
is recommended that you use this with an aftermarket
intake for best results. Also if used with a stock
intake you may have to modify either the intake system
or modify the in-line blower, this is an option, but
not recommended.
NOTE:
Both Versions of the
Electric Supercharger 8,000rpm version and 24,000rpm
version are built and installed using the same
methods. We highly recommend the 24,000rpm unit with
the Cobalt motor as it will produce much better
airflow than the cheaper 8,000rpm unit will
For
use on aftermarket intakes, simply insert the blower
in the intake right before the air filter. Please
make sure the airflow arrow is pointing towards the
engine.
If you are installing in a factory intake you may
have to modify the intake or the blower. Once again,
please take note that I do not recommend modifying
the intake.
Once you get the fan-installed reconnect the air
filter.
Next connect a
piece of the 12 gauge wire to the ground terminal of
the battery, and then run the wire neatly to the
ground wire (black) on the fan. Please be sure to
note that the keyword in the previous sentence is
NEAT, you don't want it coming loose and getting in
the way of moving parts, plus you want it to look
good don't you!
Now you will
connect a piece of 12 gauge wire to the positive
terminal of the battery and run it neatly to the
throttle body, be sure to leave about 3 inches of
wire to work with here, you will need it later. As
mentioned before, keep the wire neat and secure!!
Need to have it look good!!
Next you will have
to run a piece of 12 gauge wire from the
in-line-blowers positive wire up to the throttle
body, once again you will want to secure the wire
neatly and leave about 3 inches to work with here.
Next you will want
to connect the 2 wires to the Mini switch.
Be sure to properly
wrap any bare wires around the switch with the
electrical tape so that they will not touch each
other or something else if they come loose. Another
option is to wrap the wires in heat shrink tubing,
but this is up to you.
Now, with
everything hooked up, press the button and make sure
the fan comes on. If it does not, be sure to check
all your connections and make sure they are all
secure.
Now comes the tough
part. Depending on your car, you will have to mount
the switch in a position where it is activated
during wide-open-throttle. Below is a picture of my
car where you could mount the switch on the throttle
body so that the switch is depressed only at
wide-open-throttle. The Red mark represents where
the switch would be mounted, the blue mark is the
part of the throttle that would come in contact with
the switch at wide-open-throttle. The second picture
is the how it would look at wide-open-throttle, so
you can see how it would depress the button.

Depending on
your vehicle, you can install the button in a way that
your throttle depresses the button and turns the fan on
at wide-open throttle. If you can't seem to find a way
to mount the switch anywhere on the throttle body; you
can alternatively run the wires into the cabin and mount
the switch so that the gas pedal will push the button
when it is stomped to the floor, which would be at
wide-open-throttle. This part of the installation, you
are partly on your own because you will have to take
different approaches depending on what car you have. Be
sure you really mount the switch well, you do not want
it to come loose and interfere with the operation of the
throttle, this would be very dangerous, not only for
your car, but for your safety also.
If this should ever happen, be sure to shut off your
engine, but do not turn the key so much that your
steering will lock on you. An alternative to doing this
is to just put your car in neutral until you can come to
a complete stop and then shut your car off, this will
eliminate the possibility of your steering locking up
before you can come to a complete stop. This method may
be a little harder on your engine, but it is much safer
for you.

Diagram 1: As you can see the
electric supercharger fits onto your intake system
just as any regular aftermarket cold air intake
would. The only difference is the electric blower
unit is inserted between the MAFS and the actual
intake tube. Although it is not entirely necessary,
we highly recommend using a cone air filter as part
of your intake. This will allow much better airflow
and ensure that the air coming into your engine is
cool.
Diagram 2:
This diagram outlines the wiring procedure for
the supercharger. You can also see how the
supercharger connects to the relay and accelerator
pedal switch. If at all possible print these
instructions for easy installation.

Pictures of Components and Installed Electric
Supercharger
The cobalt motor is
used in conjunction with the Watt-Age 3" fan to produce
the 24,000 rpm supercharger. The unit is available for
only $34.99 from:
http://www.hobbypeople.net/gallery/131480.asp
The Watt-Age 3" or 4"
fans are capable of spinning up to 24,000rpm under a 12
Volt power source. These units will produce roughly 3
ft. pounds of air pressure or about a 1-2psi equivalent
boost under most applications. The complete fan with
pre-installed motor is available for only $26.99 from:
http://www.hobbypeople.net/gallery/131401.asp
For maximum results we recommend replacing the fans
stock motor with the above mentioned cobalt motor!

M3.
NOTE: For even greater performance you can always double
up the boost by using 2 electric superchargers in-line
with each other. This can be extremely effective at
producing great horsepower gains.
