The Turbosmart GenV ProGate50 External Wastegate is a motorsport-proven, high-flow 50Â mm wastegate engineered for extreme exhaust bypass capacity and precise boost control in high-output turbocharged applications. As the highest-flowing 50Â mm external wastegate in the GenV lineup, the ProGate50 is designed for engines requiring maximum exhaust control, superior thermal stability, and long-term durability under sustained high-boost conditions.
Part of Turbosmart’s fifth-generation external wastegate platform, the GenV ProGate50 represents a complete ground-up redesign. Aside from the mounting orientation, every component has been re-engineered using CFD optimization and in-house flow bench validation to improve flow efficiency, reduce turbulence, and enhance thermal and fatigue performance beyond previous generations.
The modular GenV architecture provides exceptional installation flexibility. The actuator base and cap can be independently clocked, allowing full 360-degree orientation to accommodate tight engine bays without compromising reference hose routing or service access. Actuators are interchangeable across the GenV range, enabling builders to tailor the wastegate configuration to specific packaging constraints or future upgrade paths. Optional liquid actuator cooling is available for applications exposed to extreme exhaust temperatures.
Constructed from a high-temperature 347 stainless steel body and featuring a Nitronic 60 valve guide, the ProGate50 is built to withstand severe thermal loads while maintaining precise, repeatable valve control. A high-quality diaphragm design ensures linear valve movement and consistent boost regulation across the operating range, improving response and stability regardless of spring configuration.
Each ProGate50 is supplied with a full spring kit for boost pressure tuning and features 1/8" NPT reference ports for fast, responsive boost signal control.
