One other thing to consider about Porsches and oil pressure; the oil pump also doubles as a replacement for what would be a water pump if they weren't air-cooled. Because of this, the pumps are very large, nearly over-kill. Compare one side-by-side to a detroit example. They engines survive on oil volume as well as pressure. Many of the circulation speed secrets of the detroit models are alreadt applied from the factory in a P-car, such as double-drilled and chamfoured oil passages in the crankshaft. Again, my the thery on oil pressure; if it doesn't knock or explode, it's suffecient.
