The air intake scoops, ducts and
air cleaner are locked together by latches and matching recesses molded into the mating joint faces.

The air cleaners are located in the forward corners of the engine compartment, on the fender front aprons. Each air cleaner is
located on the related fender front apron and front side member by two supports, and secured to a bracket at the top of the
fender front apron by a bolt and grommet. AIR INTAKES, AIR CLEANERS AND AIR DUCTS

9 Support 10 Inlet connection 11 Outlet connection 12 MAFT sensor The outlet tubes and T-piece duct direct the air from the air cleaners to the electric throttle. Hose clamps connect the outlet
tubes and T-piece duct together, and to the air cleaners and the electric throttle. A grommet and bracket attached the T-piece
duct to a bracket on the RH cylinder head. The two outlet tubes and the T-piece duct each incorporate a quarter wave resonator to reduce air induction noise.
The LH (left-hand) outlet tube incorporates a connector stub for the engine full load breather pipe.
The T-piece duct incorporates a connector stub for the vacuum tube of the bypass valve actuator on the supercharger.

SUPERCHARGER AND INTAKE MANIFOLDS

The SC increases the pressure, and thus mass, of the air supplied to the engine, to increase the engine's power output. Two separate intake manifolds direct air from the SC to the cylinder inlet ports.
The intake manifolds are attached to their related cylinder heads and the sides of the SC. Two dowels locate the SC in position on the cylinder block. A charge air cooler tank top is installed on top of the SC and intake manifolds to form the air duct from the SC outlet to the intake manifolds. A charge air cooler is installed in each intake manifold.
The charge air cooler tank top incorporates four studs for the attachment of the engine cover. A NVH (noise, vibration and
harshness) pad is attached to the side of each intake manifold.

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.

Symposer System

The symposer system modifies induction sound waves of a specific frequency range, at given engine settings, to produce the
required engine sound. The symposer system consists of:
An inlet pipe and flange.
A symposer and pneumatic valve assembly. A
tuning valve and associated vacuum tubes.
An outlet pipe.
An outlet adapter.

The inlet pipe and flange transfer induction noise from the RH intake manifold to the symposer. The pipe is a push fit on the symposer and the flange, which is attached to the rear face of the RH intake manifold.
The symposer contains two pairs of chambers, one pair on the inlet side and one pair on the outlet side. The inlet pipe
connects to one of the chambers on the inlet side of the symposer, and the pneumatic valve connects to one of the chambers
on the outlet side of the symposer. A calibrated orifice in the inlet pipe connection on the symposer limits the range of sound
waves that pass through it. A 'paddle' installed in a diaphragm forms the separating wall in each pair of chambers. The paddle
is able to pivot about its lateral axis where it passes through the wall that separates the two pairs of chambers.

The tuning valve controls the application of vacuum pressure to the pneumatic valve. Two screws attach the tuning valve to the
same bracket as the symposer and pneumatic valve. The tuning valve is a normally-closed solenoid-operated valve installed in
the vacuum line between a T-connection in the brake vacuum system and the pneumatic valve. A vent cap on the tuning valve
allows atmospheric pressure into the vacuum line to the pneumatic valve when the tuning valve is closed.

The outlet pipe carries sound from the pneumatic valve to the feedback tube via the outlet adapter. The outlet pipe is a push
fit on the pneumatic valve and in the outlet adapter. A screw attaches the outlet adapter to an engine harness bracket
installed between the two intake manifolds.

Feedback Tube

The feedback tube transfers the sound from the symposer system to the resonator. Clips secure the feedback tube to the
outlet adapter of the symposer system and to the resonator.

Resonator

The resonator directs the sound from the feedback tube into the passenger compartment. The resonator is installed in the
passenger compartment side of the engine bulkhead, on two mounting grommets each consisting of an isolator and a
compression limiter. A hose seal isolates the resonator where it passes through the secondary bulkhead.
