Does your supercharger pulley sound like this?

Got it okay ill give it a test. The pulleys are all grooved the belt sits within the pulleys locked in I would imagine they would not be able to sit flush as they do if it was misaligned. But maybe it could be misaligned in some other way? Not sure.

Yeah I agree with not knowing how it would be misaligned, but it's what happened to me & that's what the Whipple response asked me to do when I emailed them. Soap should just be rubbed on edges

Yeah not sure why the vide broke but the sound is really all we need here so I didn't mess with it anymore.

Its really hard to tell where the noise is coming from when i put my head directly over the SC or the motor it just sounds like its coming from everywhere tbh i couldn't pin point it when moving my head around there + the rest of the engine noises make it harder

Without a doubt the fead bracket is installed correctly. I remember torquing those down specifically I can check again later tonight. Don't know if i can check the torque on the bolts since theres too many other parts in the way.

Maybe it is the crank pulley that thing was hard to torque down. I think my torque wrench maxed out at 20 ft-lbs below the Roush spec but to compensate I gave it about a half a turn or more with a break bar and pipe to account for that extra 20 ft-lbs.

Tbh the noise goes away after warming up for about 1-5 mins. I just tested it last night after posting. Even after driving its gone.

Maybe use a long screwdriver or Stethoscope on the blower case so you can rule out if the noise is coming from up there? Of course if you haven't done this yet.
