  In The 1000 BHP GRAND PRIX CARS the chapter on Cosworth says an output just over 1000 hp at 4 bar and 12000 rpm

   that was two turbos and at the end of the 1987 season.

   11 HP per cu in

Joe the compressor wheel diameter is 2.13" in the throat, enlarging out to 3.545". The inlet throat is at 2.216".

I was figering that somewon on this site may at some time have had some experience with these turbos, and could tell me how much off a good or bad thing thay are :|

Yes, on the inside compressor housing there is a small green plate rivited, with, AiResearch Turbocharger, s/n 2183-P415 (the - is a 1 laying down),, p/n 466476-4PM.  Also embossed on the inside comphousing is A,,, MA,,, 1,,, 0,,, B68195.

On the compressor scroll near the outlet is A/R-5,,,  M10,,, A,,, 01,,, 432251-1  A,,,, there are two areas on the compscroll that have been  ground to hide information, i am going to get these dyechecked.
