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.

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!
Picture of the installed electric supercharger on a BMW 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.
