Turbo Bearing Noise?!?

[Cubes]

What exactly does it sound like when bearings are buggered in a BB Turbo?

When the car idles there is no noise.

In neutral rev it slowly and you can hear the turbo wzzzzzzzzz then slowly spool down.

Bearings?

[MrMayhem]

is that a speedy wzzzzzsz or a scrappy wzzzzzzz

[Cubes]

It doesn't actually sound like its scrapping anything but it does sound like its coming from the back of the turbo.

i.e a slight increase in revs to 1000rpm you will hear the turbo slight go wzzz then slow down.

You don't have to make boost for the sound to be there just a slight increase in revs.

Boost doesn't affect the sound it basically increases when you increase the shaft speed.

I could also slightly hear the sound when i put my ear to the turbo and spinning its shaft.

bearings could be on the way out by the sounds of things.
