IWG75 Astra VXR TypeH 7psi – Black

Turbosmart IIWG75 Astra VXR TypeH 7psi – Black are engineered to deliver maximum boost response from your factory frame turbocharger. With an increased “working ratio” over OEM actuators, the IWG75 range provides faster boost onset and improved control across the entire RPM range.

This enhanced performance is achieved through a larger diaphragm surface area and revised internal spring design, allowing greater leverage against boost pressure and exhaust backpressure while maintaining fast, consistent response.

Running the same base pressure as factory results in earlier peak boost, a broader torque curve, and improved boost hold into higher RPM. Higher base pressure setups can further enhance performance, though ECU tuning and recalibration may be required.
