2000 7.3L turbo Air Noise

have a 2000 F 350 7.3L turbo powerstroke. Has 104K Miles. Under load pulling up a long hill when the trans drops down a gear
and rpm kicks up and throttle increases the turbo stahts to hiss then makes a sound like a high pitch bugle. Sounds like air horn like noise. when you
back off on throttle and loud air whine lowers until it stops. sounds like a air valve either not opening or closing all the way and trying to force thru it.
Any one have any ideas. The noise is deafening!

The wastegate on the turbo releases drive pressure (exhaust) at a certain point to prevent excess backpressure and excessive turbine speed. Crud can build and cause a higher pitch noise.

Does it blow black smoke? I've never heard the WG opened up before. I know it works.

It is stock. I bought it about 2 months ago and only drive it about 3 times per month pull three horse trailer with living quarters. Going up incline and under load and throttle open is when excessive noise horn sound happens. thx

Sounds like you have a loose clamp or a blown hose between the turbo, aftercooler, or intake, I would tighten all clamps and look for a torn hose.

That's what I been thinking. Except it doesn't blow any black smoke so it's getting enough air. Must be a REALLY small hole.

A loose clamp wil make a high pitched noise and not much smoke and it only happening under load from the sounds of things so I gave him the cheap and first place to start point if that checks out then OP can post for more ideas. Good luck
