Theory and Operation: Theory/Operation: Description: Turbocharger
Turbo models use a liquid-cooled (coolant) turbocharger mounted directly to the exhaust manifold. Turbocharger consists of a turbine/compressor assembly, oil supply system and wastegate.
The safety valve of the system is a wastegate that prevents excess intake boost pressure. Wastegate operation is controlled by the Turbo Boost Pressure Control Solenoid. This solenoid limits boost pressure to 8.25 psi.
