Recently I started hearing what sounds like a bearing noise coming from the accessory area. I used a screwdriver up to my ear to try and isolate where it's coming from, but it's loud on the supercharger snout as well as the alternator. The sound varies with rpm. It doesn't sound like a vacuum leak. Once you get up to speed on the road the tire and exhaust noise drown it out so I can't tell if it's still there.
Has anyone else experienced this? Any ideas?

First thought is maybe the idler pulleys.Do the simple stuff first and just watch the belt run and see if it is rubbing in that area.The alignment could be off a tad there and rubbing.There has also been rare instance of the idler pulleys coming apart.2nd thought is just take the belt off and spray it down with brake cleaner.That'll clean the belt up nice if anything got on it.And while the belt is off,check and see how much play you have on the idler pulleys.There should be near none,but a tiny bit is ok.
I would be real shocked if the problem was the bearings which are self lubing for 100 k according to specs.Only thing that could be a problem is if you are using meth/water injection could cause premature issue with bearing.

I'm not running water injection. It would be nice if it's the idlers. I guess I'll have to take the belt off. That'll be a good time to check the idlers and the pulley for play. I did try a little bar soap on the belt , but that didn't quiet it up. No rubbing is evident when it's running.
To answer stlwagon's question, I think the main unit bearings are self lubricated while the "snout" contains oil that lubricates the gears, coupler and I think the two bearings as well. There is an oil fill/ check port, so I think I will check the level in there while I am looking. I did see a little residue of oil coming from the snout where the shaft come out. I read on many forums yesterday about Eaton Magnuson blowers and people having to replace bearings and couplers in the snout. (Although the couplers reportedly make more of a rattling sound when they deteriorate.) At least that doesn't seem too big a job if it has to be done.

I took the belt off and removed the idler wheels. One is a little noisier than the other, but I'm not sure that's the problem. They're sealed, but I put a little oil on them anyway.
I also checked the oil in the snout. It was a little low so I topped it off. One thing concerns me. With the car on level ground the engine kind of points up in the front. That means that the fill port on the supercharger seems below the front of the snout. I wonder if that bearing gets any oil?
It's definitely not a vacuum leak- I started the car with the belt off and the engine was nice and quiet.

You could open your oil fill?Mine is tac welded shut,maybe that was a revison made later,dunno,lol.How many miles on your X?
So,just how loud is it anyways?I know with all the engine noise it can get deceptive in there trying to find a boost leak.I had one at the air intake temp sensor back behind the blower unit,which sounded just like it came from the snout.

It's not too loud, but loud enough to be annoying. Like a high-pitched "squeal." I had my engine underhood pad off to improve cooling before the noise started and now with the noise I had to put it back- it was REALLY annoying without the pad.
Since it wasn't there with the belt off, I don't think it's a vacuum/ boost leak.
The oil fill had some yellow adhesive holding it in place, but it came off easily with an allen wrench. I've got maybe 2,000 or 3,000 miles / 2-3 months on the X-charger.
I'm going to get a stethescope and see if I can narrow it down better.
My thoughts are: alternator, water pump, X-charger idler pulleys or X-charger snout bearings.

Heh,well,i think the way it is supposed to work is not need oil for 100k and then the whole unit should be sent out for a complete rework/makeover.
Actually,i think i would have spoke with Dave @ EE about that entire matter.If anyone knows,it would be him.He also happens to be one the nicest guys you could ever wanna deal with.
I dunno.Maybe there is something exceptional to the final design.
Here is a quick C+P off his webpage,lol.
NO SPECIAL MAINTENANCE NECESSARY
The X-CHARGER does not require any special maintenance. The supercharger head unit gearcase oil should be changed at 100,000 miles.
I e-mailed Dave, but I haven't heard from him yet.
I read pretty extensively about people's experiences with Eaton Magnuson blowers of all types (OEM and aftermarket) the other day and it seems that people do sometimes have problems with the bearings and coupler making noise. I won't be too concerned if that's the problem, it's just so hard to track it down for sure...

The couplers often have some slop in them. Every one I had made some noise.
I used a stethoscope today to try and isolate the noise and I think it is the idler pulleys. (One is worse than the other.) Dave did say that they have had some bearing failures with the idler pulleys and that they have switched suppliers. Hope that's what it is!

X-Charger Bearing Noise?
