What does the 18 inHg spring mean?

The 18 inHg spring rating indicates the boost pressure at which the blow-off valve will begin to open. This spring is suitable for many turbocharged vehicles that operate at or below this boost level. If your vehicle produces significantly higher boost, you may need a different spring.

What is the purpose of a blow-off valve?

A blow-off valve, also known as a bypass valve, releases excess boost pressure from the intake system when you quickly close the throttle. This prevents compressor surge, which can damage the turbocharger, and also helps maintain boost pressure for quicker acceleration when you reapply throttle.

About this part

Product Details

This is the Turbosmart Pro-Port blow-off valve, finished in a striking blue. It comes with a pre-installed 18 inHg spring, which is suitable for many turbocharged applications where boost pressure doesn't exceed that level. This valve is designed to vent excess boost pressure from your turbo system, helping to protect your turbocharger from damage and improve throttle response when you let off the gas.

The Pro-Port design is a popular choice for tuners and enthusiasts looking for a well-built blow-off valve that can handle boost effectively. Its construction is solid, and it's known for its reliable operation. While it's a direct replacement for many factory blow-off valves, you might need to adapt your plumbing depending on your specific setup. This valve is not CARB approved and cannot be shipped to California.
