What is a wastegate. Internal or external, a wastegate is a boost-controlling device that operates by limiting exhaust gases going through the turbocharger, controlling the maximum boost pressure produced by the turbocharger itself. A wastegate consists of an inlet and outlet port, a valve and a pressure actuator.How a wastegate works. A pressure actuator, controlled by boost pressure determines whether the wastegate is open or shut. In its resting position, a wastegate is shut, and as the boost pressure builds, force is applied to the actuator. pressure actuator, controlled by boost pressure determines whether the wastegate is open or shut.
