Intercooler: Description and Operation

Supercharger System

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

At low throttle, 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.
