What does the .9 Bar spring rating mean?

The .9 Bar spring rating indicates the base boost pressure the wastegate will target. This means it will help maintain boost pressure up to approximately 13.05 PSI before opening to vent excess exhaust gas. You can swap springs to adjust boost levels.

What is the valve size of this wastegate?

This is a 44mm wastegate, referring to the diameter of the valve and its seat. This size is commonly used in many aftermarket turbocharger setups for effective boost management.

Product Details

The spring inside this TiAL Sport MVR wastegate is rated for .9 Bar, which is about 13.05 PSI. This wastegate is a 44mm unit, meaning it has a 44mm diaphragm housing and a 44mm valve diameter. This size is a popular choice for many turbocharged applications where precise boost control is needed.

TiAL is known for making well-built wastegates, and the MVR is no exception. It features a billet aluminum actuator housing that's anodized blue for a clean look, and the internal diaphragm is made from a high-temperature silicone reinforced with Nomex. This construction helps it hold up to the heat and pressure found in boosted engine setups. The valve seat is also designed to seal well, which is key for preventing boost creep and maintaining consistent pressure. It's a solid option if you're looking to upgrade your turbo system's boost control.

Keep in mind that this wastegate is not CARB approved and cannot be shipped to California. You'll want to ensure you have the necessary plumbing and fittings to connect it to your turbo manifold and exhaust system.
