WASTEGATE TYPES Internal An internal wastegate is an integral part of the turbine housing. The wastegate actuator is commonly attached to the compressor housing with a metal bracket. External An external wastegate is a separate self-contained mechanism designed for turbochargers that don't have internal wastegates. An external wastegate requires a specially constructed turbo manifold with a dedicated runner going to the wastegate. The external wastegate can also be mounted off an o2 housing, or it 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 be achieved. Atmospheric/Divorced Wastegates These terms refer to the handling of the gases after they leave the wastegate, instead of the wastegate mechanism itself. A divorced wastegate dumps the gases directly into the atmosphere, instead of returning it with the rest of an engine's exhaust. This is done to prevent turbulence to the exhaust flow. 'Divorced' wastegate dumper pipes are commonly referred to as Screamer Pipes due to the unmuffled waste exhaust gasses and the associated loud noises they produce. See also |
