An external wastegate requires a specially constructed turbo manifold with a dedicated runner going to the wastegate. The external wastegate may be part of the exhaust housing itself. External wastegates are commonly used for regulating boost levels more precisely than internal wastegates in high power applications, where high boost levels can ...
A screamer pipe is a type of exhaust configuration fitted to some automotive turbocharged petrol engines with an external wastegate set-up, which vents the waste exhaust to the atmosphere through a separate un-muffled pipe, rather than back into the main exhaust track. This exhaust setup is known for its loud noise.
This design has a lower flow rate compared to VNT types so a wastegate may be incorporated with this design. [5] VGTs may be controlled by a membrane vacuum actuator, electric servo, 3-phase electric actuation, hydraulic actuator, or pneumatic actuator using air brake pressure. Unlike fixed-geometry turbines, VGTs do not require a wastegate. [6]

Line 1 implied internal gates only (in a turbocharger), so I generalized it so it would apply to external gates. Added information on the valve types for both internal and external wastegates. Generalized external gates, because you can use one with a turbo that has an internal gate, added blurb that this involves welding the internal gate to ...

A 3-port solenoid-type boost controller A 4-port solenoid-type boost controller (used for a dual-port wastegate). The purpose of a boost controller is to reduce the boost pressure seen by the wastegate's reference port, in order to trick the wastegate into allowing higher boost pressures than it was designed for.
