turbo keeps spinning

When I shut my truck off you can hear the Turbo still spinning. Its kinda loud making a growling noise. Anyone ever encountered that before?

mine still spins when I shut her down, but no growly noise, just whistles on its way.....kinda like a cartoon bomb dropping sound.

Mine sounds more like bearings grinding. No whistle. Other than that it performs great.

Might want to check into that a little further....sounds like you may have a bearing that's starting to go

It may be the compressor contacting the housing. If this is the case your bearings are probably a little loose, the wheel may be floating around a little more at shutdown with no oil pressure to center the shaft

Are you sure it is the turbo? I would not expect a sleeve bearing to grumble.

Could also be the fan clutch spinning down.

Mine does the same, has done it for several years and I haven't located it. Other than that it runs great.

Actually I have had my turbo apart twice to clean and did not observe any signs that the comp wheel is rubbing on the housing.
I never thought about the fan clutch tho... Interesting
