What does a wastegate do?

A wastegate controls the maximum boost pressure your turbocharger can produce. It diverts exhaust gas away from the turbine wheel when the target boost pressure is reached, preventing the turbo from spinning too fast and creating excessive boost.

What is the boost pressure setting for this wastegate?

This wastegate comes with a .4 Bar spring, which equates to approximately 5.80 PSI of boost pressure. You can swap springs to achieve different boost levels.

Is this wastegate CARB approved?

No, this wastegate is not CARB approved and cannot be shipped to California.

Product Details

This is the TiAL Sport MVR 44mm wastegate, set to open at .4 Bar or about 5.80 PSI of boost pressure. It's a well-built component designed to manage the boost levels in turbocharged engines, preventing over-boosting and keeping your engine running safely and efficiently. The black finish gives it a clean look under the hood.

The MVR wastegate is a popular choice for many custom turbo setups because of its robust construction and reliable performance. It features a high-temperature resistant diaphragm and a precisely calibrated spring that ensures consistent boost control. This wastegate is designed to fit directly into many existing turbo manifold setups, though custom fabrication might be needed depending on your specific application. Its compact size also helps with installation in tight engine bays.

When installing, ensure you have the proper plumbing for both the boost source and the exhaust return. Proper setup is key to achieving the desired boost levels and ensuring the longevity of your turbo system.
