Wastegates & IWGs

A wastegate is a valve which controls the flow of exhaust gas from an engine to the turbocharger.

By controlling the flow of exhaust gas to the turbine of the turbocharger, the wastegate can control the boost pressure provided by the turbocharger to the engine.

The wastegate needs to be correctly sized for the engine and turbocharger combination to give the end user adequate control on boost pressure.

There are two types of wastegates: external wastegates, and actuator driven internal wastegates.

IWG Actuator

An internal wastegate has the wastegate valve is built into the turbine housing.

The wastegate valve is controlled by an actuator which consists of a spring and a sealed chamber.

The sealed chamber of the actuator is connected to a pressure only source normally on the compressor cover of the turbocharger.

External Wastgate

The most common reason for investing in an external wastegate is fitting an after-market turbo or better control of

the boost and consequently the power output of your engine. Additionally,

most large frame turbochargers are not equipped with internal wastegate systems.

Most tuners will recommend an external wastegate for any engine producing 400hp or more.

Sensor Caps Wouldn't it be great to actually know what is happening inside your wastegate? Now you can! With the Turbosmart Wastegate Sensor Cap you can “see” into the wastegate, so there is no need to guess anymore. You can log the wastegate valve position and know exactly what it is doing in relation to other engine operating conditions. For example, can see at X RPM, your valve lifts Y much, which results in Z boost pressure. No uncertainty, just hard data. The Turbosmart Wastegate Sensor Cap: • Is the first of its kind on the market • Allows the user to install a valve position sensor to their standard Turbosmart 'gate by only changing the cap. • Is compatible with a wide range of popular data loggers (MoTec, RacePak, AIM, etc) • Utilises a simple 0-5 Volt sensor found in many auto parts store (or available directly from Turbosmart) • Is an off the shelf item, available for all current Turbosmart wastegate sizes: 38mm, 40mm, 45mm, 50mm, and 60mm
