IWG75 Universal Actuator (UNF) 150mm 10PSI

IWG75 Universal Actuator (UNF) 150mm 10PSI

The Turbosmart IWG75 Upgraded Wastegate Actuator is engineered to deliver maximum boost response and control for factory frame turbochargers. Designed as a direct performance upgrade over OEM actuators, the IWG75 series improves boost stability, spool, and overall engine performance across the entire RPM range.

Product Overview

The IWG75 actuator features an increased working ratio compared to factory units. This is achieved through a larger effective diaphragm surface area combined with optimised spring design, allowing greater control over boost pressure and improved response to both boost and exhaust backpressure.

When upgrading with the same base pressure as factory, you can expect:

• Earlier boost onset
• Stronger mid-range torque
• Improved boost hold into higher RPM

Running higher base pressures can further enhance performance, though tuning and recalibration may be required.

Key Benefits

• Faster boost response and spool-up
• Improved boost control and consistency
• Broader torque curve across the RPM range
• Increased boost holding capability at high RPM
• Ideal upgrade for factory turbocharger systems
