  • DUMP VALVE

    Sorry if this has been asked before.

    How loud is an aftermarket dump valve (DV26) on a standard astra VXR with no mods ?, (thats with the oe re-circ valve still operating and DV teeing into the fuel pressure reg).

    Cheers,
    Chris.

    Hi Chris,

    I dont know a tech measurement, but its not loud at all. Some have complained about it being too quiet...

    Not sure if other people mention the loudness of the dv in this thread, take a read though if you haven't already

    Hope this helps

      I`m toying with the idea of fitting a DV from Courtney Sport, however I`m in 2 minds if there really worth the money at roughly £150

      I previosuly owned a STI Subaru and the DV I had on that was amasing, however the original re-circ valve was taken off and replaced with the atmosphric DV, apparently this is not the case on the VXR`s, so I don`t quite know what the point is of fitting an aftermarket DV, as the re-circ will still be operational?

      Has anyone fitted one and if so whats your opinions?

        Well i took the gamble and bought the DV and fitting kit from courtenays yesterday for £125. Gonna fit it when it comes and see how it performs. Im going to leave the re-circ valve alone. Hopefully the noise will be enough to hear from outside the car (on full boost !! )
