Found supercharger was very low on oil. Filled up with s/c oil still has noise coming from inside do I need to replace supercharger?

Is the front snout seal leaking? You may have problems inside the snout with the coupler or bearings. Usually, you only need to repair or replace the snout, not the entire S/C.

You can replace that front bushing/bearing- the noise is usually fron the fins hitting the housing-- the bushing is on-line....
