Barney, does the Judson blower still use a drip oiler for the vanes? I
ran a Judson on a early Corvair Monza years ago. It had a oil reservoir
(a 1 qt glass jar, believe it or not) that was connected to a vacuum
port on the blower inlet side. You adjusted the oil feed (Marvel
Mystery Oil) to such and so many drops per minute at X rpm. The blower
boosted pretty well around town but the boost dropped significantly on
the highway, because the vanes heated up and warped a little, losing
contact with the inside of the housing and allowing air to leak past
them. For this reason, I don't expect many Judsons were used in road
racing. Could be wrong, tho.
I knew a guy who had a Judson on a MGA 1600, IIRC. It was a spirited
car.
Cheers,
CR
