OK so my blower rattles, seems to work just fine though, only really rattles at idle, so I figured it was the coupler. I put a piece of wood to each section of the blower and determined teh noise was indeed coming from the snout area. The blower was recently rebuilt and rattled from day one. I never rant he blower previously, I just used it to get rebuilt so no down time.
Well I finally got my hands on a 94-95 case soI decided to swap the guts from my blower to the new case. I get the blower apart and there are many scratches on the inside of the case, and I mean a LOT, but the rotors look almost new. What was really weird was when I pulled the snout off the two gears looked as though they were RUSTY, they had that rust texture but it was a dark black color probably due to the blower oil. The oil looked a rusty color inside the case but was black when poured out, it was recent replaced too, a few hundred miles ago literally.
On the inside of the rotor pack against the face plate, there was some black goo, kind of looked like rtv that I think was making the rotors not spin as smooth, but I cleaned it all up, cleaned off the gears with a wire wheel and cleaned out the rotor pack real good and dropped it in the 95 case and put her back together. My old blower had a solid coupler as well.
Well the new blower is installed and running and it still rattles. I havn't gotten into full boost yet to see if I make more boost or not, I bet the old scratched case was why my boost was still low, I was getting about 12-14 PSI on 15% OD but on a mustang motor with true dual exhaust. Stock heads and cam, stock everything.
This afternoon I plan on getting into boost to see how she feels, could the rotor pack bearings be bad? Could that cause the scratches? Cause the blower seemed fine and the rotors as well, I wonder if the damage was done before the rebuild. The rebuild consisted of all new bearings and seals, everything.
