Just bought a rebuilt one to hopefully just end the issue, I don't think the little bit of SC oil that leaked onto things could have effected

Well I looked at things today and it was a massive vaccuum leak where a bolt was missing, just need to get a bolt to put in the spot I stole one from and we should be good

but...now the supercharger makes a howling noise that is pretty freakin loud, what now?

What do you mean by howling? Any chance you can get a video showing this?

I can take a video tommorow, it changes with RPMs and seems to get quieter around 3500 RPM when you really start to hear the whine (normal)

maybe the snout bearings? I should have a snout here in a few days to swap it out with

A coupler swap shouldn't have this type of an effect. It'* very odd. Please take some pics etc while you have the vid camera.

A bad bearing can make a whine, a bad coupler will sound like the snout if full of rocks. Will know more once a video is posted.

That'* what doesn't make sense. He says he changed the seal and coupler.

But not bearings. Also, if the seal was installed incorrectly it might have rolled over and is causing the whine.
