What does the spring pressure on a blow-off valve do?

The spring inside a blow-off valve holds it closed against boost pressure. The spring's rating, like the 10 PSI on this purple spring, determines how much boost pressure is needed before the valve will open to release excess air.

Is this spring compatible with other TiAL blow-off valves?

This 10 PSI spring is specifically designed for the TiAL Sport Q model blow-off valve. It is not intended for use with other TiAL models or blow-off valves from different manufacturers.

Can I use this spring if my car is not turbocharged?

No, blow-off valves and their springs are only used on turbocharged or supercharged vehicles. They are designed to release excess pressure from the forced induction system.
