Does this Supercharger sound normal?

[CarGuy11]

Almost sounds like bad bearings to me but don't have any to compare.

packaging probably makes it hard to discern SC noise from any other belt/pulley chatter if somethings not tensioning right.

how does it react to gradual rev increase? different depending on outside air temp changes? different when the engine is cold vs warmed up?

I don't think mine has that metallic sound.

Can't tell 100% but I don't think it sounds any different from mine.

Just got mine yesterday, and noticed what I think of as a 'gravel in the gears' type sound at low RPM. I can't open the attached file, but this might be the supercharger, not the transmission. Not sure if it is normal.

Sounds louder and more ‘gravelly’ than mine did on my Evora (same engine, same supercharger). The coupler can go (it did on mine), but it didn’t sound like that. The only other thing that can go is one of the bearings.

Sounds like mine too. It always had that little chirpy noise under idle since day one.
