hx35/40 supercharger sound

At WOT my hx35/40 changes from a turbo wistle to sounding like a supercharger wine. is this normal and or could it be a boost leak? theres a little up and down shaft play, but not enough to touch the comp housing.

Well, mine does it too so I'd say it's maybe normal for it. I asked my cummins friends about it and they all noticed it. Doesn't seem to effect mine and only does it from 23psi to full bore.
