The SC is a Roots blower with high angle helix rotors driven at 2.1 x engine speed by the secondary belt of the accessory drive.
The two rotors of the SC are contained in a housing. The ends of the rotors are supported in bearings in the front cover and the bearing plate. A rear cover seals the bearing plate and incorporates a filler/level plug for lubricant. A pulley transfers power
from the accessory drive to the shaft of one of the rotors.

A pneumatic actuator on the front cover is attached to a by-pass valve in the housing. The bypass valve regulates a flow of air
from the outlet of the SC back to the inlet side of the rotors, to control the outlet pressure of the SC. Hoses connect the pneumatic actuator to the throttle T-piece of the air ducts, upstream of the electric throttle, and to the front cover, downstream
of the electric throttle. A lever connects the actuating rod of the pneumatic actuator to the shaft of the bypass
valve. A screw in the front cover limits movement of the lever in the closed direction to allow calibration of the SC output. The front cover also incorporates:

The SC air inlet and mounting face for the electric throttle. A connector stub for the part load breather.
A MAP (manifold absolute pressure) sensor.
A connector stub for a hose from the EVAP (evaporative emission) canister purge valve.
Intake Manifolds

Each intake manifold is attached to the SC with three screws and a bolt. Two dowels ensure correct alignment of each intake manifold. The RHD (right-hand drive) intake manifold incorporates a connection port for the noise feedback system. The LH intake manifold incorporates:
A connector stub for the brake vacuum system.
A MAPT (manifold absolute pressure and temperature) sensor.

Diagnosis and Testing

Principles of Operation

For a detailed description of the intake air distribution and filtering system and operation, refer to the relevant Description and
Operation section of the workshop manual. REFER to: (303-12D Intake Air Distribution and Filtering - V8 S/C 5.0L Petrol)

Intake Air Distribution and Filtering (Description and Operation), Intake Air Distribution and Filtering (Description and Operation), Intake Air Distribution and Filtering (Description and Operation).
Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.


NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection
Mechanical Electrical
Hoses and ducts (damage/connections)
Air cleaner element (contaminated/blocked)
Restricted air intake
Supercharger
Supercharger (cooling fan) drive belt
Supercharger seals and gaskets
Charge air coolers (damage/connection)
Mass Air Flow (MAF) sensor
Manifold Absolute Pressure (MAP) sensor
Manifold Absolute Pressure/Temperature (MAPT) sensor
Throttle body
Harness (security/damage)
Connections (security/damage)
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.

4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

Major air leakage (after the
supercharger) Check the supercharger and drive belt. Remove the supercharger drive
belt and recheck for noise. Turn the supercharger by hand and check
for excessive resistance. Check for excessive play at the supercharger
pulley. Check the charge air coolers. Refer to the relevant workshop
manual section.

CAUTION: If a new cylinder head has been installed, then new taptite bolts must be used to install the supercharger.
NOTES:


New taptite bolts when used cut their own threads on the first application.


Removal steps in this procedure may contain installation details.

1. Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).


2. WARNING: Do not work on or under a vehicle supported only by a jack.
Always support the vehicle on safety stands.
Raise and support the vehicle.

3. Refer to: Charge Air Cooler (303-12D Intake Air Distribution and Filtering - V8 S/C 5.0L Petrol, Removal and Installation).
