Check to make sure your power steering res is full.

My car made the same noise. Turned out I didn't clean the pulleys good after coolant spilled out when changing the thermostat. Noise went away after I replaced the belt. Once the belt is contaminated with coolant, oil, or other residue it will make that squealing sound. Try running a bar of soap on the groove side while the car is running and see if the sound goes away.

That's a good thought!!

The PS res doesn't need to be really low to make some crazy noise.

If you installed a 100mm idler pulley check to see if it's touching the pulley directly next to it.

Found the problem. We had to replace the belt. They said something fell on it, in other words it was dirty. No biggie.

Had a high pitched sound coming from my "11 coupe twice in the last couple of days.
First time I heard it I thought it was a police car or emergency vehicle.
Pulled over and rolled down the windows and it was really loud.
After a few minutes it quit.
Same thing happened the next day. Took it into the dealer yesterday.
Got a call from the dealership last night, they are replacing the supercharger under warranty (19,900 miles on car)

They had to replace mine as well under warranty. Kinda kool because the charger is what usually gives out before engine. Now we are on the up and up.
