Can't figure out why my Eaton stopped making its whine in the lower rpms. It was doing just fine and then one day no whine. Now if I really get on it she whines, but even then its not that loud. My mods are 2.8 upper, 2lb lower, home ported blower (but has had no issues til now), ported TB. I took the SC off (after the issue began) and checked it over.
When on the car you can spin it by hand with no noise. I took it apart and checked the needle bearings but they seem fine so I regreased them with high temp grease, then I took the snout apart and checked the gears etc, but they were good. Put back on and re-oiled with GM SC oil.
My boost guage doesn't work (never has and I am putting this thing back together slowly from where the last owner abused it). I can take the hose off at the firewall and blow into it hard and it moves, but I can't find a leak beyond that to the blower. The car feels like it still has alot of power but its hard to tell for sure with a butt dyno. Would a leak keep it from building enough boost to make the whine at low rpms?
There doesn't seem to be any threads on loss of blower whine with the eaton unless the Eaton is making a knocking sound. If someone knows of one, a point in the right direction would be helpful.
