Remove lower idler bolt and dust shield and discard.
Remove alternator bolts and discard.
Remove all intake ducting saving MAF and IAT sensors for later use.
Remove upper radiator support and cooling fans discard.
Remove front fascia and all splash panels to gain access to front bumper.
Remove breather line from throttle body to valve cover and discard.
Remove air pump and mounting bracket.
Remove front swaybar.
Remove cruise control from mounting bracket.
Section 2 Crank Pinning
Remove factory crank bolt and discard.
Install the supplied drill guide and lightly tighten it.
Using guide drill a ¼” hole ¾” depth past the drill guide.
Using air blow out all metal chips and install ¼ pin.
Install new GM crank bolt and torque to 250 ft lbs.
Section 3 Cooling Fans
Install new fan shroud into factory location on radiator.
Cut factory fan harness 2” back from connector on both fans.
Connect grey and black wires on factory harness to the black wires on new fans.
Connect blue and white wires on factory harness to the red wires fans.
Using the supplied loom and wire ties secure the harness from moving parts.
Section 4 Supercharger
The supercharger and bracket come preassembled to show spacer layout.
Remove idler to gain access to vent plug on supercharger.
Install vent that is wired to plug and reinstall idler and tighten.
The supercharger comes pre filled with oil. Check the level with dipstick in supercharger.
Mark driver side swaybar mount as in picture and grind to give clearance for
supercharger.
Paint and reinstall bracket.
Install the two longer studs into alternator bracket and shorter into idler mount.
Install spacers as shown in picture. DO NOT REUSE DUSTCOVER ON IDLER
Install serpentine belt as shown in picture before install supercharger assembly.
Install supercharger assembly to studs. Tighten nuts. Install front swaybar.
Install new tensioner with provided spacers and hardware. Install tensioner brace as
mentioned in side instructions in bag.
Install serpentine belt as in diagram.
Section 5 Intercooler
Remove foam bumper and fascia support.
On the steel bumper you will see a hole in the center of the bumper. Use this as a
reference and mark 13” to the right and left of the bumper as seen in the picture.
Using the intercooler as the template, center it on the top market lines and mark the lower
section of the bumper. Use a straight edge and draw a line attaching both points on the
bumper as seen in the picture. Cut bumper on line with sawsall or bandsaw.
Trim radiator shroud as in picture to give clearance for intercooler.
Position the washer pump as in picture for intercooler clearance.
Install steel mounting bracket on intercooler. Using bracket as guide, drill 4 3/8” holes in
the newly cut bumper. Tighten all hardware.
Trim the lower fan shroud to splash panel mount as in picture for discharge pipes.
We recommend reinstall the foam bumper to support the front fascia and to allow better
airflow to intercooler. Trim foam bumper as in picture with a hot knife or sawsall.
To gain better airflow the front fascia can be modified. Here is a picture of a Camaro
fascia cutout with a Street Scenes Grill. ( NOT INCLUDED IN KIT )
Section 6 Discharge Pipes
The cruise control will need to be moved to give clearance for discharge tubes. Remove
the cruise control wiring from the factory harness and re loom with loom provided. Move
harness as shown.
Remount cruise control with sheet metal screws as shown.
Bend horn bracket to give clearance for discharge pipes.
Install discharge pipes as shown. Tighten all T-Bolt clamps
We did not drill the upper 70 degree pipe for the IAT Sensor. Drill a ¾” hole in pipe and
install supplied grommet.
On Firebirds it will be necessary to relocate the headlight motor actuator from the fuse
box for pipe clearance.
Install upper radiator mount as shown above with rubber mounts from factory mount.
Re install front fascia. On Firebirds it is recommended to leave driving lights out for
more airflow. Additional trimming will be necessary on Firebirds to clear intercooler.
If air pump will be reused, there is some modifying to the brackets to mount it up. Use
pictures below as a guide to modify it.
Section 7 Air Intake
Install the supplied silicone, elbow, coupler and filter as shown. We have included a
restrictor in the air filter to lower boost to a safe level on a stock engine. This can be
removed if higher boost #’s are desirable.
Install 3/8” fuel line from passenger side valve cover to air filter. Drill bottom of air filter
to install 3/8” barb 90 degree. Attach fuel line to the fitting.
Install 3/8” vacuum cap on fresh air vent on throttle body.
Cut the ½” brake boost line and install supplied vacuum tee. Run 3/16” vacuum line to
bypass valve. A vacuum tee has been provided for boost a pump or boost gauge.
Install the check valve into the lower PCV hose with the arrow pointing towards the
intake manifold.
The lower splash panels will need to be modified to clear the discharge and intake tubes.
Use the pictures below as a reference on how to trim the panels.
Next the lower fascia will need to be trimmed to fit flush against the bottom of the
intercooler core.
Using a 2.5” diameter holesaw drill out the three mounting holes on the lower fascia and
trim to lay flush against the lower portion of the intercooler core.
Secure with double sided tape that is provided.
Install the S-Shaped bracket to the lower bolt on the hood latch support bracket. Using
this bolt install the bracket so it pushed up on the lower radiator shroud against the back
of the intercooler core to allow the most airflow to the radiator.
Section 8 Fuel System
Install supplied injectors into factory rails. Apply a small amount of lube or WD-40 to
injector o-rings when installing.
Install the Racetronix pump and harness upgrade per Racetronix instructions.
It is highly recommend to replace the fuel filter when doing a pump change.
Install the new NGK spark plugs and gap them to .035”.
NO ECM TUNING IS INCLUDED WITH THIS KIT
We recommend for the best results to have a local shop to do a custom tune on the dyno.
If this is not an option, we recommend PCMFORLESS.COM for all mail order tunes.
WARNING: DO NOT OPERATE VEHICLE WITHOUT ECM TUNING
Section 9 Final Check
Check all fittings, nuts, bolts and clamps for tightness. Pay particular attention to lines
and hoses around moving parts, sharp edges and exhaust parts. Make sure all wires and
lines are properly secured with clamps or wire ties.
Check all fluid levels, making sure that your fuel tank is filled with 91 octane or higher
fuel before commencing test drive.
Verify that both cooling fans are working in the high and low settings.
Verify that the serpentine belt is on all the pulleys.
Check to make sure you have the proper tune in the vehicle.
Re check to be sure that no hoses, wires, ect are near exhaust headers or moving parts.
Look also for any signs of fluid leakage.
PLEASE TAKE A SPECIAL NOTE: operating the vehicle without ALL the sections
completely and properly installed may cause FAILURE OF MAJOR COMPONENTS.
Test drive the vehicle.
Always listen carefully for engine detonation. Discontinue heavy throttle usage if
detonation is heard.
