do not buy a snout until you think you know for sure whats wrong, most likely its not your snout i had the same problem. i thought it was the snout so i replaced the snout with a brand new Eaton m90 and a zzp coupler still made noise then i replaced the blower housing and rotor pack with a used one still mad noise but not as bad guessing it could be the needle bearings? im getting a blown l67 for free from my friend he says the supercharger is good so im gonna try it and throw that on. my car sounds find with the s/c belt off so im guessing its gotta be something with the s/c.. my tensoners do seem a little worn and should be replaces but i have a stethoscope and i hear the noise inside the s/c so idk i guess ill find out when i rip it apart again..
