GENV COMPGATE40 EXTERNAL WASTEGATE 14PSI (SLEEPER)
Part # TS-0552-1015

(0 reviews) Love it

The GenV WG40 CompGate40 External Wastegate is a Motorsport-proven, cost-effective external wastegate – The highest-flowing wastegate of its kind. The GenV provides extensive user configuration, world-leading extended thermal performance, fatigue resistance and best-in-class flow performance for optimum control and longevity. 

The GenV Range has more features, options and performance than any other gate. The GenV External Wastegate from Turbosmart was a ground-up rework of a classic, and the only feature that rolled over from the Gen4 range was the mounting orientation. CFD optimized and validated in-house for maximum flow and thermal management.  

A direct fit upgrade to all Gen4 Turbosmart wastegates and feature our unique collar-locking system, variable actuator cap and base for easy, 360-degree optional routing of reference hoses, strap-type V-band clamps, optional liquid-cooling provision, 1/8″ NPT reference ports and are provided with the full range of available springs.
