IWG75 Ford Focus ST / XR5 2.5L Turbo 7 PSI

IWG75 Ford Focus ST / XR5 2.5L Turbo 7 PSI

Turbosmart IWG75 Ford Focus ST / XR5 are engineered to deliver maximum boost response from your factory frame turbocharger. With an increased “working ratio” over OEM actuators, the IWG75 range improves boost control, spool response, and consistency across the entire RPM range.

This improved working ratio is achieved through a larger diaphragm surface area and revised internal spring design, providing greater leverage against boost pressure and exhaust backpressure while maintaining fast, precise response.

Running factory base pressure delivers earlier peak boost, a broader torque curve, and improved boost retention into higher RPM. Higher base pressure setups can further enhance performance, though ECU tuning and recalibration may be required.
