Here's another data point.
Canadian 1982 930 so its a ROW engine, stock except for K27-7200 and recurved distributor (which I have no detail on since the tech that did it retired). 251,000 km (155,000 miles) on the engine which had a valve job at 200,000km. Doesn't use much oil between changes, oil pressure is well within spec, and generally runs great except for a minor warm start issue which I hope the Leask WUR will take care of.
Seems to be in-line with what would be expected for a stock ROW engine with a K27-7200 though I was pleasantly surprised by the torque figures.
We had a handheld AFR gauge in the car and video'd the tach, boost and AFR together. Boost threshold is 2,100 - 2,200 rpm, with 0.8 bar at about 3,000 rpm in 4th gear. The richest it got to was 12.8 and settled at about 13.3 at max boost, so its definitely running lean. If anyone can tell me how to post the video I will do so (.avi).
I'm dropping it off tomorrow with my tech so in a few days it will have Brian's headers and muffler, tial wastegate and Leask adjustable WUR. Valves will be adjusted, timing will be set and we'll get the AFRs where they should be, then I'll post a follow up dyno run to see what I've gained.
