Distribution and Filtering - Overview
Description and Operation

OVERVIEW
The intake air distribution and filtering system comprises:
Dual air intakes, air cleaners and air ducts.
A SC (supercharger) and intake manifolds.
A noise feedback system.

SUPERCHARGER System Operation

At closed or partially open throttle positions, the bypass valve is fully open, allowing a flow of air from the SC (supercharger)
outlet back to the inlet side. This results in little or no pressure increase across the SC. Progressive opening of the throttle reduces the depression downstream of the electric throttle. This is sensed by the pneumatic actuator, which moves to close
the bypass valve. As the bypass valve closes there is a corresponding increase in the outlet pressure from the SC, which increases engine power output.

NOISE FEEDBACK SYSTEM

Sound waves from the RH (right-hand) intake manifold are filtered by the calibrated orifice in the inlet pipe connection on the
symposer. The sound waves make the paddle oscillate and generate pulsations in the outlet chambers. When the pneumatic
valve is open, the pulsations are transmitted through the outlet pipe and feedback tube to the resonator in the passenger
compartment.

The tuning valve of the noise feedback system receives a power feed from the power distribution box and is connected to
ground through the ECM (engine control module). At lower engine loads and speeds the ECM keeps the ground open circuit and the tuning valve is de-energized closed. Atmospheric pressure is sensed at the pneumatic valve through the vent cap on the
tuning valve, which keeps the pneumatic valve closed and prevents sound from the symposer entering the feedback system.

At higher engine loads and speeds the ECM connects the tuning valve to ground. The tuning valve energizes, blanks off the atmospheric vent and opens the vacuum line between the brake vacuum system and the pneumatic valve. The depression in
the brake vacuum system is sensed at the pneumatic valve, which opens and allows sound from the symposer into the
feedback system.
The status of the pneumatic valve at various engine loads and speeds is given below:

Pneumatic Valve Status

NOTE: Values are for valve opening with increasing engine load and speed. Deduct 0.05 g/rev and 50 rev/min for valve
closing with decreasing engine load and speed.

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.
