Turbo Whistling

Recently (past week), my '93 9000 CSE has developed a condition where, on cold start, it would emit a loud, high pitched whistle under boost (I live at the bottom of a hill, so I'm immediately in boost climbing the hill) -- loud enough that the neighbors turn and stare. Once under way, the whistling would stop, and the car seemed to perform normally.
Today, the whistle turned into a throaty "whoooooo" (think blowing across the top of a pop bottle). The noise didn't go away with warmup, and now the boost gauge only goes to about mid scale, and there's no descernible performance boost (is this what it feels like to drive a normally aspirated car? How do people stand it? )
Any suggestions on what's wrong, or where to start looking?
