Sanden A/C

I just installed a Sanden conversion kit in my 78 SC. The compressor hose fittings didn't fit under the condenser on the decklid, so I had to mount the compressor sideways, with the fittings on the right instead of on top. Much less power drop compared to the York, but the Sanden is kinda noisy. My old York was quiter, except at 2500 rpm where it produced a sound similar to a 757 charging the runway. The Sanden produces a sound like my shop air compressor, pretty uniform but a little worse when the engine is under load, at starts and hills and such. I wonder if mounting the unit sideways is causing oil starvation issues? I've been assured it will work this way, but I don't want to ruin a brand new part. Anyone know anything about this?

Well, problem solved. I feel kind of stupid replying to my own post, but I thought I would share this with anyone else who might be doing a Sanden a/c upgrade. My problem was that the pulley on my compressor was not square to, and in line with, the drive pulley on the engine. This caused the belt to travel at an angle, and it was exerting side forces against the compressor and it's bearings. When installing a Sanden a/c compressor, there is so much lattitude on positioning the compressor that it is easy to get it wrong. Basically what I did to fix it is eyeball the path of the belt from the left then right side of the car, checking that the belt's path is a straight line from and around each pulley. Then I measured the clearance from the a/c belt to the fan housing top and bottom, and kept fiddling until they deviated by no more than 1/16th inch. This got everything straight and square. By the way, the Sanden is awesome. No noticeble power loss on freeway ( a little bit at idle), and temp drops in a different leage than my old, worn out York.
