I think what you're talking about is turbo bark. this happens when you are revving, causing the turbo to spool up, then suddenly release the throttle. I don't know why you would want it as it can cause turbo failure (broken shaft I think)

Are we talking about the short choppy "chooo chooo chooo" sound when you let out of the throttle at high rpms, or the "whoooosh" sound like when shifting gears? Like the sound at the end of THIS video?

Isn't the "flutter" referred to as turbo surge? When the throttle is suddenly chopped at high boost pressures there is nothing forcing the the turbine to spin therefore causing the remaining air on the compressor side still has to be forced out of the turbo. But with the high pressure air fighting the now effortless compressor it cause it to flutter. Sound right?

Maybe its not even "bark" he is referring too. After you let off the pedel on High boost, or elevated boost pressures, the still exsisting boost pressure is no longer needed in the turbo to be forced into the intake so the boost pressure is dumped thru the Waste gate. That is more than likley what you may be hearing. I hear it in mine everyday and it is the wastegate dumping boost out before it gets spooled into the intake.

During acceleration and haring the whistle fo love from the turbo and then letting off the pedel, you will hear a long accentuated "WHHHOOOOOOSH".

This is waste gate dump, not bark. Am I correct here. Someone chime in.
