[s-cars] new noise to figure out

[Calvin & Diana Craig]

Sounds like the bypass valve to me.  This is one of two noises I have heard
it make, the other is a "honking" or "groaning" like sound.

 Hi,
   My wife's 95.5 S-6 Avant is making a high pitch HMMMMM at a certain load
on the engine just before boost comes on. I can get it to do it at all RPM's
and it does not change pitch with rpm. It is most common when going up a
slight hill while just maintaining speed with boost not yet coming on as far
as I can tell. She does not have a boost gauge but it feels like it happens
around 0 to maybe 1 or 2 psi. Any Ideas? I am stumped and it seems to be
happening more and more. Thanks for any help.

Elijah
