A/R is a term that relates to the "Area to Radius" of the housing. The bigger the number the more air it will flow, however the smaller the quicker it'll spool. VERY over simplified, but that should help. The a/r # is cast into the housing both intake and exhaust side. Aluminum is the intake or compressor side and the cast iron side is the exhaust or hot side of the turbo. Hope this helps. Turbocharger Kindergarten. Now I'm spent.
