    Post Corsa VXR Back Whistle

    any ideas on this one guys?
    When putting an air filter on my car you get the good sound from the secirculatory valve but it's followed by a nasty back whistle?

    Sounds somewhat like this;

    any ideas what causes that? I've seen some cars with the same set up that don't have the same issues?

    Cheers!

    I have k/n cone with samco hose its normal .


    Want to make ur car sound like a turkey lol take diverter valve pipe of turbo and stick a bolt itto the pipe. Then drive. All waste air will dump throw ur filter.. But dont drive to hard ur valve will lift at around 13psi and ur car will run poo.

    Or get a dumpvalve.oem dv blank plate and reroute the boost pipe to the sensor on the back of inlet manifold. Thats how wayne/vxrs runs.. . Waaaaatussss
