    Hey, got a 97model A3 1.8t

    standard dumpvalve packed in so i bought a dumpvalve off ebay (forge)

    its an atmospheric twin piston one, ( i know you all reccomend re-circ's but i want abit of noise :))

    any way, i fit the blanking plug in the air intake..

    fit the dumpvalve to the metal boost pipe at the back of the engine and fit the vacum hose.

    It is not dumping at all ?? it does blow off ever to slightly at real high revs but hardly

    what can cause this??

    Is not the forge adjustable as I'm sure it is!

    From what I read it has 2 springs inside that counter balance each other, where did you stick the blanking plate as this is new to me, I assume its blocked a hole on the valve which maybe has stopped the other spring from functioning which inturn then stops its from dumping properly, just ideas as I havnt used one of these ones as yet, you got image of the setup & valve so I can see it better?
