INSTALLATION INSTRUCTIONS
PLEASE READ CAREFULLY
This kit should only be installed by qualified mechanics. It is imperative
that the correct air/fuel mixture be maintained at all times. This Universal
Kit is to be supplied to competent engine tuners for their completion by
the addition of, and tuning of, an appropriate carburetor unit and fuel
pump.
This product is intended for use on healthy, well maintained engines.
Installation on a worn-out or damaged engine is not recommended and
may result in failure of the engine.
Vortech Engineering is not responsible for engine damage. Installation on
new engines will not harm or adversely affect the break-in period so long
as factory break-in procedures are followed.
For best performance and continued durability, please take note of the following
key points:
1. Use only premium grade fuel 91 octane or higher (R+M/2).
2. The engine must have stock or lower than stock compression ratio.
3. If the engine has been modified in any way, check with Vortech prior to using this
product.
4. Always listen for any sign of detonation (pinging) and discontinue hard use (no
boost) until problem is resolved.
5. Perform an oil and filter change upon completion of this installation and prior to
operating the vehicle. Thereafter, always use a high grade SF rated engine oil or a
high quality synthetic, and change the oil and filter every 3000 miles.
6. Before beginning installation, replace all spark plugs with one to two step colder
heat range and reset timing to no more than 26°-28° total. (Always follow the pro-
cedures indicated in the factory repair manual.)

PREPARATION/REMOVAL
A.
B.
Disconnect the negative lead to the bat-
tery.
F.
(Serpentine) Remove the power steer-
ing pulley from the power steering
pump. Loosen the screws securing the
pump and remove the pump from the
factory bracket. Temporarily lay the
pump in the engine compartment.
Remove the fan and shroud to aid in
installation. It may also be necessary to
install a fan spacer at a later time.
C.
(V-Belt) Loosen all nuts and bolts that
are used to tension the alternator and
power steering pump V-belts. Remove
the factory belts.
G.
H.
(Serpentine) Remove the factory cast
bracket from the driver’s side of the
motor.
(V-Belt) Remove the factory power
steering pump from the motor.
D.
E.
(Serpentine) Loosen tension on the ten-
sioner and remove the factory drive belt.
(Serpentine) If so equipped, loosen the
two screws securing the alternator to the
cast factory bracket on the driver’s side.
Remove any other electrical connections
to the alternator. Remove the alternator
from the bracket and set aside.
V-BELT NOTE: This kit is designed to work
with later model V-belt power
steering pumps. The power steer-
ing pulley shaft should be Ø3/4"
and is not threaded at the end.
2.
OIL FEED INSTALLATION
A.
B.
The supercharger uses engine oil for lubrica-
tion and must have an oil feed line connected
to a filtered oil access point on the engine.
Remove the 1/4"NPT plug located on the
engine block just above the oil filter boss.
Replace the plug with the supplied 1/4"NPT x
90° elbow and 1/4"NPT x -4 flare fitting.
NOTE: Use clean engine oil on the pipe threads.
Teflon tape and sealant is not recom-
mended as it might loosen and cause
blockage of the small oil feed orifice
resulting in supercharger failure.
C.
Connect the supplied feed line to the flare fit-
ting and route it up to the front of the driver’s
side cylinder head. Secure the hose with tie-
wraps away from exhaust heat, chaffing
and/or sharp objects. Temporarily cover the
open end from debris until the connection is
made to the supercharger.

OIL DRAIN INSTALLATION
A.
To provide an oil drain for the supercharger, it
is necessary to make a hole in the oil pan.
Locate and mark the hole location. (See Fig.
3-a.) It is best to punch the hole rather than
drill.
NOTE: Removal of the oil pan may ease oil
drain fitting installation on some applica-
tions.
B.
C.
Remove any paint from around the hole area.
Use a small center punch to perforate the
pan and expand the hole, switch to a larger
diameter punch and expand the hole further
to approximately Ø9/16". Most punches are
made from hexagon material and may be
placed in a socket with an extension to make
this procedure easier. Use caution so that the
hole is not enlarged too much and that the
punch does NOT contact the crankshaft.
D.
E.
Tap the hole with a 3/8"NPT tap approximate-
ly 1/4" deep. Pack the flutes of the tap with
heavy grease to hold the chips. Use a small
magnet to check for any stray chips.
NOTE: This method of rolling over the lip of the
hole and tapping works well if carefully
done and should cause no problems.
Thoroughly clean the threaded area. Apply a
small amount of silicone sealer to the new
threads. Apply more sealer to the supplied
3/8"NPT x 90° elbow and secure in the previ-
ously threaded hole. Make sure a seal is
formed all around the fitting. Rotate the fitting
so that the oil drain hose can be easily routed
to it. Apply sealer to the supplied 3/8"NPT x
1/2" beaded hose barb fitting and install in
the previously installed 90° elbow.
DOWN 2"
F.
Drain the engine oil, install a new filter and
refill with fresh oil.

4.1 MAIN BRACKET/SUPERCHARGER INSTALLATION (Serpentine)
.360" L-SHAPED SPACER
NOTE: Some applications (depending on intake
manifold height) may require the reclocking
of the supercharger volute. If reclocking is
required for your application, loosen and
remove the six 1/4-20 cap screws and retain-
ing plates that hold the compressor housing
(volute) to the gearcase. If the compressor
housing does not rotate freely relative to the
gearcase, DO NOT FORCE IT. SERIOUS
SUPERCHARGER DAMAGE MAY OCCUR.
The machined mating surfaces are designed
to prevent pressurized air from escaping and
have minimal tolerances. If the housing will
not move or is very tight, contact Vortech
Engineering immediately at 805 247-0226
and ask our service department for further
assistance.

DISCHARGE DUCTING/CARBURETOR ENCLOSURE
NOTE: OPTIONAL: Due to the many possible con-
8M012-012
figurations of intake manifolds (with regard
to carburetor flange height) a carburetor
spacer may be required to obtain the neces-
sary height for proper supercharger and dis-
charge duct alignment. As an option, the
carburetor enclosure cover may be turned
around so that the inlet is facing the passen-
ger side of the vehicle. This may be desir-
able on some vehicle applications with tall
intake manifolds or for vehicles with other
clearance issues. (See Figs. 6-a, 6-b for
more detail.)
This optional discharge arrangement
requires the supercharger to be sent into
Vortech for a volute exchange to a straight
discharge unit (a curved volute is originally
supplied on the supercharger).

FINAL REASSEMBLY AND CHECK
WARNING: Do not attempt to operate the vehicle
until all components are installed and all
operations are completed including final
check.
A.
B.
C.
Refit the upper fan shroud.
Reconnect the battery.
If your vehicle has gone over 15,000 miles
since its last spark plug change, you will need
to change the spark plugs now before test
driving the vehicle.
D.
E.
Check all fittings, nuts, bolts and clamps for
tightness. Pay particular attention to oil and
fuel lines around moving parts, sharp edges
and exhaust system parts. Make sure all
wires and lines are properly secured with
clamps or tie-wraps.
Check all fluid levels, making sure that your
tank(s) is filled with 91 octane or higher fuel
before commencing test drive.
F.
Start engine and allow to idle a few minutes,
then shut off.
G.
Recheck to be sure that no hoses, wires, etc.
