Dean had this with his S8 and it was the bearings in the compressor. We put a new one on and the noise was no more.
I actually had to label the compressor so I knew it was duff and didn't make its way in to 'good used stock', since you couldn't feel anything untoward spinning it by hand, and the clutch was fine. It was only under load at engine speed that it made the noise.
