Im gonna be on here quite frequently as I rebuild my car. It was bought in a million pieces and im reassembling it.
I noticed while routing the engine harness that I have an open port on the back side of the supercharger. Its about 1/2 inch diameter, 1 1/2 inches long, with a bead rolled edge, which has me thinking its a coolant passage. Now, this car has a heat exchanger and I have a bunch of loose ends of hose that have yet to be determined attachment points. Is this one of them? Any help is greatly appreciated.

 

There may be an installation manual at soec.org
