Will a smaller pulley change the sound (whine) of our superchargers?

@PolePosition to have a smaller Pulley installed your Hellcat would need to be Tuned and have the supporting mods to go along with it.

My Hellcat is modified and with the smaller pulley more spin so yes, the sound does change.
You could always go on Youtube and watch videos of stock Hellcats vs Modified to hear for your self.

It be like turning your fan from low to high! It's going to make more noise and spin faster.

Thanks. I don't have any experience modding cars, but I'm interested in the new Mopar Staged Performance Kits that Dodge is putting out. Stage II, and presumably Stage III, for the Redeye includes a smaller pully, air filter, 180 degree thermostat, and tune--and nothing else. So I was wondering if it would change the supercharger whine. When I searched on YouTube, I couldn't find an example of someone with just a pulley and tune. By the time people swap the pulley they have usually already done cold air intake, headers, and mid-muffler delete. The mid-muffler delete in particular makes it very difficult to hear the supercharger. Anyway... Thanks again!
