What does the 2 PSI rating mean for my blow-off valve?

The 2 PSI rating means the spring will hold the blow-off valve closed until your turbo system builds at least 2 pounds of boost pressure. This allows for precise control over when the valve vents excess boost.

Can I use this spring with other brands of blow-off valves?

This spring is specifically designed for the TiAL Sport 34mm QR Blow-Off Valve. Using it with other brands or different valve sizes is not recommended and may not function correctly.

What is the benefit of using a lower boost threshold spring like this one?

A lower boost threshold spring, like this 2 PSI purple spring, can be beneficial for smaller turbochargers or systems where you want the blow-off valve to release excess pressure sooner. It helps prevent over-boosting by venting pressure at a lower point.

Product Details

This is the TiAL Sport 2 PSI spring, color-coded purple, designed for their 34mm QR blow-off valve. If you're running a turbo system and need to fine-tune how your blow-off valve releases excess boost pressure, this spring is a key component. It allows you to adjust the valve's opening threshold, ensuring it only vents boost when it reaches a specific pressure level.

The purple spring is rated for 2 PSI, meaning your blow-off valve will only open when your turbo system builds at least 2 pounds of boost. This is a lower boost threshold compared to the standard spring, which can be beneficial for smaller turbochargers or systems where you want the valve to react sooner. It's a well-built part from TiAL Sport, a popular name in the forced induction world, and is designed to work seamlessly with their 34mm QR blow-off valves. Swapping springs is a straightforward way to adjust your boost management without altering engine tuning.

Keep in mind that this spring is not CARB approved and cannot be shipped to California. Always refer to your turbo system's requirements and consult with your tuner to ensure this spring is the right choice for your specific setup.
