It is all about control 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 in the actuator. Creating 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 the Twin Port IWG-75 ideal for traction limited applications, such as front-wheel drive or drag racing vehicles. The IWG-75 is released to suit Borg Warner’s EFR range of high performance internally wastegated turbochargers, along with a universal fit model, with more applications coming in the future. The Turbosmart wastegate actuator range has been designed as a stronger, more reliable replacement for OEM parts. Like all Turbosmart parts, billet construction means they are stronger and more durable than a stock actuator, while Turbosmart’s focus on performance means boost comes on faster and holds on longer. The Turbosmart IWG-75 actuator range features: • Stable boost control• Improved boost response• Flatter boost curve in the top end• Interchangeable springs for a great range of boost levels Supplied With: Fitting Hardware, Brown/Purple 7psi Middle Spring and Brown/Pink 7psi Outer Spring (installed).
