System Description

Supercharger Components:

The supercharger is a positive displacement pump. Its purpose is to supply an excess volume of intake air to the engine by increasing air pressure and density in the intake manifold. The supercharger is matched to the engine by its displacement and belt ratio, and can provide excess airflow at any engine speed.


The supercharger system is a blow-through type with the fuel injected directly into the intake ports. The supercharger is belt driven off the crankshaft through an idler pulley. The throttle body controls the amount of intake air to the supercharger through the intake plenum. Air from the supercharger is routed through the intercooler, then to the intake manifold. The resulting denser air charge in the combustion chamber provides for a higher power output of the engine over a non-supercharged engine of the same displacement.


At part throttle opening the engine runs under vacuum due to normal intake restrictions. To prevent supercharger cavitation, reduced performance and increased temperatures, a vacuum-controlled bypass valve is installed at the supercharger outlet. The bypass valve allows a controlled amount of the airflow from the supercharger outlet back into the supercharger. As the throttle opening is increased, the actuator closes the bypass valve, directing all the air from the supercharger to the intake manifold. This occurs as soon as the throttle opens, resulting in immediate response.


The supercharger is not a bolt on option. It is part of an integrated engine system. Many components of the supercharger engine are not interchangeable with similar parts from a non-supercharged engine.

The supercharger contains two three-lobed rotors. The helical shape and specialized porting provide a smooth discharge flow and low level of noise during operation.

The rotors are supported by ball bearings in front and needle bearings in the rear. The drive gears are pressed into place, therefore the supercharger is replaced as a unit, and is not serviceable.

INTERCOOLER

The intercooler cools the pressurized air from the supercharger, increasing the air density, which improves combustion efficiency, engine horsepower and torque.



LUBRICATION

The supercharger has a self-contained oiling system that does not require a fluid change for the life of the vehicle. However, the fluid level should be checked every 30.00 miles. If the fluid is low, add a synthetic supercharger fluid that meets Ford specification ESE-M99C115-A, such as E9SZ-19577-A or equivalent.
