Overview

The Turbosmart Gen V WG40 Compgate 40 is an external wastegate designed for maximum user-adjustability and performance. It features interchangeable actuators, allowing a smaller actuator to be used on a larger body for fitting into tight spaces. The unique variable adjustment design enables independent orientation of the actuator base and cap relative to the weld flanges for flexible positioning.

This wastegate boasts increased thermal and flow performance compared to rivals, with integrated liquid cooling ports for further thermal management if needed. It includes a selection of springs for fine-tuning boost performance and features 1/8″ NPT ports for optimal response and flow. The modular construction ensures it is upgradeable and serviceable.
Show original supplier description
The Turbosmart Gen V WG40 Compgate 40 external wastegate represents the fifth generation of Turbosmart's wastegate technology, focusing on enhanced user-adjustability without sacrificing performance. Its design allows for interchangeable actuators, meaning a smaller actuator can be fitted to the larger wastegate body, making it suitable for installations in confined engine bays. The unique variable adjustment system permits the actuator base and cap to be oriented independently of the weld flanges, providing up to 12 positions for precise alignment and convenient fitting of associated hardware. Engineered for superior performance, the Gen V Compgate 40 out-flows its competitors and features improved thermal management over previous models. For applications requiring extreme thermal control, integrated water cooling ports are included. The wastegate utilizes a diaphragm design that ensures linear travel irrespective of spring pressure and valve position, contributing to improved response. It comes with a spring kit for fine-tuning boost levels and is equipped with 1/8″ NPT ports for maximized response and flow while maintaining broad compatibility with various fittings. The modular construction of the Gen V Compgate 40 makes it fully serviceable, with all components designed for easy removal and upgrade. Tested for over one million cycles, it promises exceptional reliability. This wastegate is noted as a 'Race Only' product and does not have a CARB EO #, meaning it is not legal for sale or use in California on pollution-controlled motor vehicles. Included in the box are the Gen V Wastegate, a valve seat, inlet and outlet V-band clamps and weld flanges, a collar tool, a spring kit, and a fitting kit.
