    T8s new dump valve!!

    well after everybody was raving on about the colins dump valve i got myself one. I swapped the baileys trumpet valve for the colins and it makes a totally different noise. The baileys seemed like a very short tssh but this seems more like a tsssssh. Not sure if i like it yet and i need to here it from outside to get the full effect.



    i was to excited to wait so i squeezed T8 in the garage



    new and old DV.

    also got my total closure kit through and will hopefully get my fmic kit tomorrow

    Try blanking the OE dv off. Makes it much louder.

    Got to agree with this fitted the car is slow and sluggish on boost. Couldnt wait to get rid of it tbh.

    Try not fitting a dump valve at all and see if your car drives better or not.

    Agreed. It does run shite on its own or even with the OE plumed in as well. But it does sound good.

    Running the OE valve only is the best for boost. It is just a trade off.

    I have a Forge diverter valve that I will be fitting instead of the OE valve, and that should improve the situation.
