Whenever I got WOT I hear a whining noise coming from the engine, what could that be?

I thought about popping the hood but I figured it would be easier to ask teh interwebs for guidance.

I have a loud whistling sound coming from my engine. I messed around with vacuum hoses and such....and I thought I got it, but an hour or so later it was back. Sounds like a bomb being dropped. Damned if I could figure it out. Any ideas???
 
So I took a look under the hood with the wife revved it and it definitely sounds like it is coming from this shoebox looking thing sitting on top of the engine?
