Turbosmart V-IWG Mk8 Fiesta ST FORD - 4inHg TS-0602-2046

Turbosmart Upgraded Vacuum-operated Wastegate Actuators have been developed to provide the maximum possible boost response for your factory frame turbocharger. The Turbosmart vIWG Series of upgraded Actuators benefit from an increased Working Ratio over the factory equipment resulting in improved boost response, throughout the RPM range.

This Improved working ratio is achieved through an increase to the effective surface area of the diaphragm and revisions to the actual springs fitted resulting in greater leverage of the forces the actuator is working against (boost and backpressure) while still being super-responsive.

Upgrading with the same base pressure as factory, you can expect a broader boost and torque curve through peak boost being achieved earlier in the RPM and being held longer, into higher RPM. These improvements can be amplified with higher base pressures, however tuning and recalibration is recommended for optimal performance.

Features:

• Proprietary Silicon Nomex Diaphragm
• High-Grade Billet Aluminum Construction
• Stainless Steel Rods and Clevis
• Turbosmart Unique Locking Collar System

This is a bolt-on fitment for the factory turbocharger as fitted to the Mk8 Ford Fiesta ST Turbo engine with a pneumatic vacuum actuator.
