B&M supercharger noise problem.

I bought a used 144? B&M supercharger, made a new intake manifold, and installed it on a Dodge 241 Hemi engine. It runs good, revs good, everythings fine untill you put it in drive. In drive, under load at idle, there is a loud racket coming from the front of the supercharger. Once you get above idle, the noise goes away. Can anyone help me? Is this something i have to live with, or can it be corrected? Thanks, Mike.

it sounds like it will be ok but i wonder if it is the belt causing it.in the winter maybe have it checked in the front gears!

Thanks for the info. The noise is a rattle sound, and is louder than i want to live with. A friend is checking into having it looked at by his supercharger builder.
