What is the primary benefit of the 'Motorsport' version of this wastegate?

The Motorsport version includes an integrated heatsink designed to keep extreme heat away from the actuator. This significantly extends the service life of the actuator and ensures more consistent performance in demanding, high-temperature environments like endurance racing.

Can I adjust the boost pressure setting on this wastegate?

Yes, this wastegate comes pre-set to 14 PSI. Optional springs are available separately, allowing you to change the boost threshold to suit your specific engine tuning needs.

What materials are used in the construction of this wastegate?

The wastegate body is made from high-temperature 347 stainless steel, while the valve guide and seat are constructed from Nitronic 60. The internal springs are 17-7 PH stainless steel, all chosen for their durability and resistance to extreme heat and stress.

About this part

Product Details

If you're building a high-performance forced induction system, managing boost pressure is critical, and that's where an external wastegate like the Turbosmart WG40 Gen V Comp-Gate 40mm Motorsport comes in. This unit is designed to precisely control the boost generated by your turbocharger, ensuring it stays within safe and optimal limits. The 'Motorsport' designation means this wastegate is built to handle the extreme heat and stress found in endurance racing and other demanding applications, offering improved durability and consistent performance when you need it most.

Turbosmart has taken their Gen V modular wastegate design and added a CFD-designed and real-world validated heatsink. This component sits between the wastegate body and the actuator, creating more distance and using both convection and shielding to keep harmful heat away from the actuator. This is crucial because excessive heat can significantly shorten the life of the actuator and its internal components. The wastegate itself features a 347 stainless steel body and a Nitronic 60 valve guide and seat, materials chosen for their high-temperature resistance and durability. The 17-7 PH stainless steel springs are also built for fatigue resistance, ensuring consistent operation over time. The actuator housing can be rotated or 'clocked' to help with plumbing in tight engine bays, and it uses strap-style V-band clamps for a secure and easy installation.

This particular model is set to 14 PSI, but optional springs are available separately if you need to adjust the boost threshold. Turbosmart also offers optional accessories like a position sensor to monitor wastegate actuation and even liquid cooling for the actuator for the absolute most extreme setups. While this wastegate is designed for maximum performance and longevity, please note it is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and plumbing.
