Default Weird noise when engine revs

'o1. Motor sounds good at idle, until you rev it up. Then it makes a noise, almost like a bearing spinning. This noise goes on until I turn the a.c. on. Turn ac off, noise back. Standing over motor, sounds like it's coming from the top, but I wanna believe it is the compressor. Any ideas?

Could be the compressor. You can take that belt off and run the engine. That would help "eliminate the unknowns"

I'd think your description is enough to narrow it down!
