squeak from pulley?

This has been happening since I bought the car but as soon as I accelerate I get a quick squeak, almost sounds like a short burn out, really brief though and definitely coming from the front, under the hood or suspension component. Anyone experience this? almost sounds like something needs to be oiled, more then likely I'm assuming replaced though.

Probably the supercharger clutch engaging

Yes. It's normal. The entire supercharger starts spinning when it engages so there is quite a bit of weight being rotated, that makes the clutch chirp a little

AOT
I to have this same noise. What RPM is this happening at OP?
I thought I read that the clutch doesn't engage/makeup until 2k RPM? Mine has the squeak your speaking about normally between 1500-1800RPM when I quickly apply throttle.

Maybe this is not the SC belt causing this noise? Possibly a worn serpentine belt?

When i was at the shop today inquiring he said it is normal, its the sc pulley engaging. He said he can make it quieter by doing something or other, but its normal and nothing to worry about.
