What is the purpose of a blow-off valve spring?

The spring inside a blow-off valve holds it closed against intake manifold pressure. It's calibrated to open at a specific boost pressure, releasing excess boost when you lift off the throttle to protect your turbocharger.

How do I know if I need a 2 PSI spring?

The ideal spring pressure depends on your vehicle's boost levels and the specific blow-off valve. A 2 PSI spring is suitable for applications where you want the valve to start opening at very low boost pressures, typically around 2 pounds per square inch.

Does this spring come with any other hardware?

This product includes only the 2 PSI spring for the TiAL Sport QR blow-off valve. Other components of the blow-off valve, such as the diaphragm and housing, are sold separately.

Product Details

This is the TiAL Sport QR BOV 2 PSI Spring in black, designed for their 1.5-inch QR blow-off valve. If you're running a turbocharged or supercharged vehicle and need to fine-tune your boost pressure management, this spring is a key component. It allows you to adjust the opening pressure of your blow-off valve, which is crucial for protecting your turbocharger and maintaining consistent boost levels.

The spring's primary job is to hold the valve closed against intake manifold pressure until your set boost threshold is reached. A 2 PSI spring means the valve will start to open when boost pressure hits approximately 2 pounds per square inch. This is a well-built replacement part that ensures your blow-off valve functions correctly to vent excess boost pressure when you lift off the throttle, preventing compressor surge and extending the life of your turbo. It's a straightforward swap for the existing spring in your TiAL Sport QR BOV.
