The GenV CompGate40 HP external wastegate is a Motorsport-proven, cost-effective 40mm external wastegate with base spring pressure options of up to 50 psi! Add some reference signal manipulation, and you have a 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.Â
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.

What makes this an HP (High Pressure) Gate?
The unique actuator housing is slightly taller than a normal GenV gate, allowing for taller, high-pressure spring options. The normal GenV actuator housings have been made as small and low profile as they can be, while still offering base pressure options up to 26psi - Higher than that and you'll want an HP version.
Â
What spring options does the GenV HP range have?
You effectively have 5 options: 10psi, 25psi, 35psi, 40psi, and 50psi with the use and combination of just three springs. And remember, this is just base mechanical spring pressure. Much higher boost levels can be achieved with some type of boost control or reference manipulation.
Â
Are all the springs in the box?
Almost - While the 10psi and 25psi come pre-fitted in the gate, an optional 40psi spring is available as an accessory.
Â
How much boost can the GenV HP Gates handle?
How much have you got? All setups are different, and to answer this question, it’s best to acknowledge how much exhaust back pressure impacts boost control. On an efficient setup, you should be able to achieve between 2 and 3 times the base mechanical spring pressure. However, if you’re really working a turbo, efficiency tends to drop off, and back pressure rises, making things a lot harder. It really does come down to your combination.
Â
Do I need to use the Water Cooling?
Not necessarily. The Water cooling feature is there simply as an option. The GenV architecture provides class-leading thermal management, so it’s our experience that most users will never need it. It's there if you’re among the few finding the limits, though.
Â
What size are the reference fittings?
The boost control reference ports and the (Optional) liquid cooling ports are 1/8NPT. We have a range of AN adapters and high-temperature push-lock fittings available in the Spares and Accessories Tab.
Â
Can I rotate the top housing?
Yes. The modular design of the GenV Range of External Wastegates means you can rotate the actuator housing 360 degrees, for virtually unlimited hose routing options.
