Turbosmart Twin Port Internal Wastegates

Turbosmart IWG75 Twin Port Internal Wastegate Actuator

IWG-75 Actuator

The Twin Port IWG-75 uses the air pressure differential between two sealed chambers to create a dynamic force which overcomes the mechanical spring force of the actuator.This technology results in a boost curve that is much more precise, and allows for a much wider boost range between minimum boost and maximum boost than the single tier control offered by conventional actuators.This makes it ideal for traction limited applications, such as front-wheel drive street or drag racing vehicles.

The Twin Port is currently available to suit Borg Warner’s EFR range of high performance internally-wastegated turbochargers, along with a universal fit model which can be used with our range of clevis rod ends, with more applications coming in the future.The entire Turbosmart wastegate actuator range has been designed to be a stronger and more reliable replacement for OEM type parts.
