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.
Wastegates – Internal Wastegate Actuators
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.
Wastegates – External
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.
Description:
Mitsubishi Evo Internal Wastegate Actuator (IWG) provides better turbo response and greater sensitivity when managing boost pressures. Designed as a direct bolt-on replacement for the factory part, the Mitsubishi Evo IWG is easy to install and requires no special tools or fabrication. We’ve taken the proven technology from our WG38, 40 and 45mm External Wastegates and applied it to the Internal Wastegate Actuator. FEATURES: Silicone diaphragm with Nomex reinforcement to withstand high temperatures. High grade, billet aluminium construction. Stainless steel rods and connecting clevis for corrosion resistance. Locking Collar design cap allows for quick spring changes (Options from 3psi to 26psi).
