Nuke Performance BOV50c Magenta Discharge Spring -0.40 to -0.52 Bar

Interchangeable adjustment springs for the Nuke Performance BOV50c blow-off valve, available in six different versions, ideal for any boost pressure level.

Ideal for any pressure level, thanks to its adaptability with a wide selection of interchangeable adjustment springs to suit your specific needs. The Nuke Performance BOV50c V-Band blow-off valve offers unmatched flexibility with a selection of six interchangeable adjustment springs, ideal for any pressure level. The BOV50c includes a pre-installed blue spring, and changing to another spring is very easy thanks to its three-bolt design.

* The BOV50c is equipped with a pre-installed blue spring.** For supercharger applications only.

Select the blow-off valve spring pressure based on the engine's vacuum reading at idle, when the engine is at its ideal operating temperature. The boost pressure is not related to the spring pressure; it only depends on the vacuum. The lowest stiffness spring (light gray) is specifically designed for superchargers and is not suitable for use with turbochargers. These springs are only compatible with the Nuke Performance BOV50c blow-off valve. First-generation BOV50 blow-off valves use a different series of springs.
