A couple updates:

1. I'm now using a short AN-10 extension so the two right angle hose fittings don't interfere with each other. I got Vibrant 10588.
2. I updated the air pressure sensor on the accusump to the N55 10 bar oil pressure sensor, part 12617592532. It's amazing how high the oil pressure gets in the accusump compared to the motor. I don't know if it's resistance through the filter or what but I do see spikes of 9 bar at times.

I'm going to try going back to the stock oil cooler and weld an AN-8 aluminum bung onto the place where the N55 oil pressure sensor usually goes. I'll bore out the passageway too to make sure it can flow enough oil. A racer with an E46 B46 used the stock oil cooler successfully so I think I have a chance. If not, I can upgrade to the oil/coolant heat exchanger used on the M6 GT3 :-) It's only $140....
