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.

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.

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.

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).

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.

Test drive the vehicle.

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.
