    tie a knot in the pipe that leand off the top of the dump valve and put a air filter on it such as a k and n and it will be loud!

    What you have to remember is that the cause of the flutter noise is potentially damaging to the turbo, so not something you want to promote.

    when we first built my engine i had loads of waste gate chatter and was only running 6 psi. now im running 16psi the wastegate chatter is bearly audiable over the B.O.V.
    id rather have BOV noise over w/gate chatter anyday.

    Its not called wastegate chatter, its the air that can't be released, due to something like the the wastegate not working, reverbarating against the turbine blades. Although it sounds good, it is very very very bad, will kill turbos in no time.

    Forgot to say its actually called compressor stall.
