Wastegate Valve W/ Engine At Idle
At idle and partial engine loads, the turbo charger air pressure in the intake manifold is low and the wastegate valve stays shut.
Wastegate Valve W/ Engine At Full Load
At maximum engine loads and RPM, the intake air pressure generated by the turbo charger is very high and can exceed its allowed limit. The wastegate
valve then opens, limiting the maximum turbo boost pressure.
