I have an update. I ran the car without the supercharger belt (what a dog) and the noise came back. That all but eliminated the blower, sort of.
Still baffled, I took some video of the car with the noise and without. I tried posting those yesterday, and was told that my post would have to be approved by the Mods. I assumed my low post count and video links threw up a red flag. I also assume the Mods are busy guys with jobs and they didn't get to it. So if you really want to hear it, go to youtube and search for silo32.
Then, I talked to a friend about this and mentioned the PCV valve. Crazy right? No. To make a long story short, I changed the PCV valve, the O-ring and the gasket on the cover plate and now for two days the noise is gone. I think what was happening was the cover plate gasket was leaking and the squealing/whining noise was actually a hissing sound. When you shut the car off the vacuum/pressure on the two sides of the PCV valve was "resetting" and the noise would go away until the pressure built back up.
A couple months, a couple hundred bucks in parts and several years off of my life span, and it turned out to be fixed in less than 15 minutes for less than $10.
