Is this noise my water pump?
A few months ago I thought I had a super charger failure, so I took the whole thing apart only to find everything ok. While it was apart I changed out the super charger oil with the GM stuff and cleaned everything up ect. There was no abnormal wear, all the gears looked in great shape.
More recently I have noticed a new whistling type noise which seems to be coming from the super charger\water pump area. I cant attach MP3's here so here's a link to the sound. Its most noticeable when the revs are coming back down. I have never heard this noise up until a few days ago and it seems to be getting louder. Anyone have any ideas?
I have an 2003 R53 with 73k miles.

Long story short, it was the PTO gears in the SC. I called up Dustin at autoxcooper and arranged to have the SC rebuilt. I got the entire SC rebuilt and the rotors re-coated. They also repaired my m7 pully. Turn around was great (3 business days) and it came back better than new. As usual Dustin hooked me up with great service.
