I have the ss/sc 07... i dont know if this is normal but when my car is running sometimes i hear like a soft rattling noise as if something is spinnig and like loose or somehting...its hard to explain but mayb someone knows what im talking about...thanks

 

i hear the same thing in my 06 ss/sc...espeacilly in 1st gear when im decellerating or going around a slow corner...sounds like its coming from the right side of the engine bay or opposite of the superchargers air inlet. I hear the same spinning sound...could this be the supercharger's internal gearing? i Hope this is normal i have owned the car for a total of three days.

 

i heard sometimes the coupler inside ur SC wears pretty easily, i'm thinking the one chevy puts in there stock isnt that great, i hear the rattling coming from my SC all the time, do this, after running ur car for 15 or 20 minutes (maybe after goin somewhere) open ur hood and listen to the SC and see if maybe that is it. ZZperformance offers a new coupler and is not expensive at all... check it \/ \/
