Turbo chatter after fitting intake..good or bad for turbo?

[18Edition30]

After fitting my ITG maxogen I can get t to chatter/flutter perfectly by releasing throttle mid boost and blipping throttle again, just wondered if this was bad for the turbo?!

Read somewhere its trapped air going back through the turbo the wrong way or something. Damages the fins and bearings.

And ITG was too loud and sucky so got myself the Volkswagen Racing enclosed kit and its perfect, no suck but still chatters when wanted, also seems to be quicker than with the ITG.

So guys good or harmful for car?

Afaik it's air hitting the fans of the turbo and its not great for your turbo. But I'm certainly no mechanic

I cant see it being an issue... the same will be happening without the intake, you just cannot hear it!

no it is not hitting the turbo ,the air that comes to the intake pipe from the DV  has that "chatter"ish sound

[WHOZBOSS]

I would say its good

[LeonCR]

Didn't think an intake will "make" it do that, all it does is amplify the sound

I thought it was called "wastegate chatter"? where the wastegate is flapping open and closed?

Its normal turbo noise that you dont hear with the oe engine cover.

So is it turbo or wastegate chatter I'm hearing then? If there different.

An if it always does it then it not harmful right?
