Does anybody know what might be the sounds of a supercharger with a low oil level, or one with an overfill?? (of course,, if any sounds exist) THANXXX

 

They make a sort of "Boom shakalaka ting ting boing boing" noise

Actually, I don;t know having never done either to my blower.
Undo the fill plug and check the level. It should just weep out. If it does, you are good to go. If it pours out, you have too much and if none comes out, you need to fill it.

What sort of noise do you have? If it's a ticking noise from the top of the engine, check your spark plugs for tightness immediately. Don't drive it.
