## Features

- Material: Aluminum Alloy. External Diameter: 25mm
- The dump valve can be fully adjusted to suit your specific boost pressure / application. This valve is rated to 2.0 Bar / 30 Psi at full adjustment, so is more than capable for most 25mm applications.
- Dump valves are fitted to turbo engines to release intake pressure generated by the turbo once the throttle has shut (lift off), as a result of this pressure being released you get a (much desired) audible whoosh noise at gear change/lift off.
- These valves also protect your turbo by reducing thrust damage to turbo bearing typically caused by compressor stalling.
- Atmospheric (Noisy) and Partial Recirculation (to aid MAF equipped cars)
