I have the audi workshop manuals and I will look through them, but I only have it for our engines not the 3.2

    3.2 and 3.0 is should be the same oil value and capacity! I'll this time I was talking about oil pressure but value of the flow is very important too. Let's think logically, same block ! same oil channels , just a different style of the pump..... Audi engineers did variable oil pump to make engine more efficient and they save some mpg due low pressure true 1k-5k rpms so this is the main reason why they did variable oil pump. Cut oil pressure to save gas so stupid! I just not getting how pressure is controlled in 3.2 Engine, there is no pressure control in then pump except over pressure relive valve! By pictures I posted, oil pressure control by two check valves on then top, same as I posted in video at FB grope. btw I opened my group called " Boosted world " I will post ill my data and progress there as well video.

    Have you considered a dry sump? I believe it would solve any oil pressure and capacity issues even if you spin the engine higher.
