Comptech SC Idle Noise: Ideas?

[4RE-NVME]

Guys,

Since I've had my CTSC installed (a couple years), it's always made a somewhat unpleasant "grumbling" or "growling" noise at idle. It sounds like it's coming from the SC drive mechanism.

Any ideas?

Note from page 8 of the CompTech supercharger install manual:

"Start car and again check for any fuel or vacuum leaks and unusual noises. At idle, supercharger will make somewhat of a "growling noise" due to gear lash. This is normal and nothing to be concerned about (unless it seems excessive) and will go away off idle."

Thanks Nick. I 'spose I earned a RTFM for that one!

IMO, this is the only thing I don't like about the CTSC as it makes the engine seem a little junky at idle. I wish there were a way to minimize this...
