The GenV HyperGate45 HP external wastegate is a Motorsport proven, cost effective external wastegate with base spring pressure options of up to 50psi! Add to that some reference signal manipulation and you have some serious boost! 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 like it.
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 and 1/8″ NPT reference ports.
