PRODUCT DESCRIPTION
The GenV WG40 CompGate40 external wastegate is a cost-effective, race-proven external wastegate: the highest-flowing wastegate of its type. The GenV offers extensive user configurability, world-leading extended thermal performance, fatigue resistance, and best-in-class flow performance for optimal control and durability.
The GenV range has more features, options, and performance than any other wastegate. The Turbosmart GenV external wastegate was a complete overhaul of a classic, and the only feature kept from the Gen4 range was the mounting orientation. Optimized and validated in-house using CFD for maximum flow and optimal thermal management.
A direct fit upgrade for all Turbosmart Gen4 wastegates, it features our unique collar-locking system, variable actuator cap and base for 360-degree optional routing of reference hoses, strap-type V-band clamps, optional liquid cooling provision, 1/8" NPT reference ports, and is supplied with the full range of available springs.
Available in Black, Blue, Red, Purple, and Motorsport colors. Optional wastegate position sensor. Compressed gas (e.g., CO2) version. Motorsport version (CFD-based heatsink design). High-pressure (HP) version up to 50 psi. Electronic actuation (eWG) version.
Features: Class-leading thermal performance. CFD and bench-validated flow performance. Class-leading fatigue resistance. Nitronic 60 valve guide and high-temp 347 stainless steel body. 17/7 PH stainless steel springs. Liquid actuator cooling option. Strap-type V-band clamps.
