Hmmm...  If the belts are definitely new, I'd say to check the tension 
on them.

The turbo whine?  Sounds like an Audi 5 cylinder.

If I were to have to diagnose it, I'd probably try to determine which 
belt it is.  First try just to look and listen with the hood up standing 
in front of the car revving the throttle.  If you can't tell, and it 
bothers you enough, you could begin by removing the A/C belt, seeing if 
it goes away, then the power steering belt, then the alternator belt.  I 
wouldn't drive this way, just for diagnosis.

It's most likely a belt, just as you might think.  I'm curious to hear 
that it's the throttle body screw, tho'.

Oh yeah, I'd replace the timing belt.
