A. Refit the fan and shroud (if equipped).
B. Fuel pump boost reference hose connection:
Connect a suitable boost reference hose to
the mechanical fuel pump (or to the regulator
if an electric pump and bypass-style fuel sys-
tem is employed) to a positive pressure
source upstream of the throttle valve. This
source can be a port (installer provided)
located on the supercharger discharge tube
or carb hat/enclosure. Ensure that the
source that you select supplies only positive
pressure under all operating conditions.
C. Reconnect the battery.
D. 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.
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.
F.
Check all fluid levels, making sure that your
tank(s) is filled with 91 octane or higher fuel
before commencing test drive.
G. Start engine and allow to idle a few minutes,
then shut off.
H. Recheck to be sure that no hoses, wires, etc.
are near exhaust headers or moving parts
and for signs of any fluid leakage.
I.
Re-jet the carburetor as required. Install a
boost referenced high-performance mechani-
cal fuel pump or high performance electric
fuel pump with boost referenced fuel regula-
tor. Use a wide band O2 sensor to verify a
proper air/fuel ratio (Vortech suggests 11.0:1
for 91 octane pump fuel).
J.
Check ignition timing to make sure it is prop-
erly set before commencing test drive.
K. PLEASE TAKE SPECIAL NOTE: Operating
the vehicle without all sub assemblies com-
pletely and properly installed and working
may cause
fAILURE Of MAJOR ENGINE
COMPONENTS.
L.

7. 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.
For internally lubricated V3 units
only
This supercharger has been factory pre-filled
with special Vortech synthetic lubricant. Oil
does not need to be added to a brand new unit;
however a fluid level check should be per-
formed.
Prior to operating the supercharger on the ve-
hicle and after installation onto the vehicle:
Remove the factory installed flat-head brass
shipping plug (not the dipstick) from the top
of the supercharger case. Replace the sealed
shipping plug with the supplied “vented” plug.
Do not operate the supercharger without it.
Check the supercharger fluid level.
Fluid level checking procedure:
1. Ensure that the .06” copper sealing
washer is located on the dipstick base.
2. Thread the clean dipstick into the unit until
it seats.
3. Once the dipstick has seated, remove the
dipstick from the unit. Fluid should register
in the crosshatched area on the dipstick.
4. DO NOT OVERFILL!!! Drain excess fluid
from the unit if it is above the maximum
level on the dipstick.
Check the fluid level using the dipstick at least
every 2,500 miles.
Initial supercharger fluid change must be per-
formed at 2,500 miles. The supercharger fluid
must be changed at least every 7,500 miles.
Drain the fluid, refill the unit with 4 oz. of
Vortech V3 lubricating fluid and then confirm
proper oil level using the dipstick. DO NOT
OVERFILL!!!
WARNING: Use of any fluid other than the
special Vortech lubricant will void
the warranty and may cause com-
ponent failure.
