The GenV WG50 ProGate50 External Wastegate is a Motorsport-proven, cost-effective external wastegate � The Highest Flowing 50mm External Wastegate in the World. The GenV provides extensive user configurability, world-leading extended thermal performance, fatigue resistance and best-in-class flow performance for optimum control and longevity. 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, the GenV range has more features, options and performance than any other gate. 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.
