The wastegate controls how much boost the turbocharger can produce by limiting the speed that the turbine wheel is allowed to spin. The actuator opens a valve (wastegate) and allows exhaust gasses to bypass the wheel, limiting boost to a preset level. Many earlier turbocharged BMWs use a vacuum-controlled actuator assembly, while later model F chassis and newer vehicles use an electronic wastegate actuator.
The Turbosmart GenV range is the Highest Flowing Wastegate range in the World. The GenV WG38 UltraGate38 External Wastegate is a Motorsport proven, cost-effective external wastegate. 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 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, optional liquid-cooling provision, 1/8″ NPT reference ports and are provided with the full range of available springs.
