I had a loud growling noise coming from what I'm pretty sure is the supercharger so I took it off and there is a very very slight scratch on one part of the rotor it's not notched or anything I'm going to send it out to be ported and polished and get new needle bearings I was wondering is anyone has either rebuilt a snout and also need to know if you need to install the boost bypass actuator a specific way when putting back together thanks
