What does the PSI rating on this spring mean?

The 11 PSI rating indicates the minimum boost pressure required to overcome the spring tension and open the blow-off valve. This helps protect your turbo from over-boosting by releasing excess pressure.

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

This spring is specifically designed for TiAL Sport's 29mm QR blow-off valves. Using it with other brands or different valve sizes may not provide a proper seal or function correctly.

What is the benefit of changing the BOV spring?

Changing the spring allows you to adjust the boost pressure threshold at which the blow-off valve actuates. This is useful for fine-tuning your turbo system after engine modifications or ECU tuning to maintain optimal boost levels and protect your turbo.

Product Details

If you're tuning your turbocharged vehicle and need to fine-tune your boost pressure, this TiAL Sport QR BOV 11 PSI Spring is a solid option. This red spring is designed to work with TiAL Sport's 29mm QR blow-off valve, allowing you to set your desired boost level. It's a straightforward way to adjust how your blow-off valve operates without needing to replace the entire unit.

This spring is well-built and intended for use with the TiAL Sport QR blow-off valve. The 11 PSI rating means it will hold boost up to that level before the valve starts to open, helping to protect your turbocharger from over-boosting. Swapping out the spring is a common practice when upgrading other turbo components or when you've changed engine management settings and need to re-calibrate your boost threshold. It's a simple mechanical adjustment that can make a notable difference in how your turbo system performs.

Remember that this spring is not CARB approved and cannot be shipped to California. Always ensure your modifications comply with local emissions regulations.
