thanks marc for the reply,
i guess i didnt word the question correctly. you see, ever since i changed the belt, the car just doesnt 'feel the same' when supercharger kicks in, there seems to be a slight 'lag' in response.
i thought that maybe in process of changing the belt, the supercharger pully may have rotated slightly so it was not in the same position when i installed the new belt. is there such a thing as 'timimg' that needs reset?
