The Turbosmart GenV WG40 CompGate40 External Wastegate is engineered for motorsport performance and reliability. As the highest flowing wastegate of its class, the GenV WG40 offers advanced user configuration, extended thermal performance, and exceptional fatigue resistance for consistent boost control and long-term durability.

This wastegate features a fully re-engineered design with CFD-optimized flow paths and in-house validation for superior flow and thermal management. It is a direct-fit upgrade for all Gen4 Turbosmart wastegates and incorporates a unique collar-locking system, variable actuator cap, and a 360-degree rotatable base for flexible reference hose routing. The wastegate uses robust strap-type V-band clamps and includes 1/8" NPT reference ports, optional liquid-cooling provisions, and a complete range of springs for precise boost control.

Available finishes include Black, Blue, Red, Purple, and Sleeper. Optional upgrades include a wastegate position sensor, compressed gas (CO2) actuator version, motorsport heat sink version, high-pressure (HP) version rated up to 50psi, and electronic actuator (eWG) version.
