What does the PSI rating on the spring mean?

The PSI rating on the spring, in this case 11 PSI, indicates the minimum boost pressure the turbocharger needs to build before the spring is overcome and the blow-off valve opens. This helps ensure you don't vent boost at lower engine loads.

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

This spring is specifically designed for the TiAL Sport QR (Quick Release) blow-off valve model with a 1.5-inch inlet. Using it with other brands or different valve sizes may not provide a proper seal or function correctly.

How do I know if I need to change my blow-off valve spring?

You might consider changing the spring if your blow-off valve is opening too early and causing boost leaks, or if you've changed your vehicle's boost levels and need to match the valve's opening pressure. This 11 PSI spring is a common choice for many turbocharged applications.

Product Details

TiAL Sport is well-known for making high-performance turbocharger components, and this blue 11 PSI spring is a perfect example of their focus on precision. This spring is designed to be used with their QR (Quick Release) blow-off valve, which is a popular choice for many turbocharged vehicles. The spring's main job is to control when your blow-off valve opens to release excess boost pressure. An 11 PSI spring means the valve will stay closed until your turbocharger builds up at least 11 pounds of boost, ensuring you don't leak pressure at lower levels.

This particular spring is blue and is made to fit the 1.5-inch inlet size of the TiAL Sport QR blow-off valve. Swapping out springs is a common way to tune your blow-off valve's performance to match your specific turbo setup and desired boost levels. It's a well-built component that helps maintain consistent boost pressure and protects your turbocharger by venting excess pressure effectively. If you're looking to fine-tune your boost control or replace an old spring, this is a solid option.
