The graph looks very good. What all did you do to your engine/oiling system to get these successful results? Is it a proprietary system?

My previously posted graph shows the oil pressure going up and down wildly in response to G forces. This is what is happening inside most M96 or M97 engines when they are being driven hard.
It is not uncommon for the oil pressure to drop below 1 bar due to G forces. I accidentally and expensively proved to myself that the oil pump generates about .75 bar worth of air pressure even without any oil in the engine. So, if the pressure is below 1 bar there is essentially no oil being delivered to the bearings. The engine fails once it accumulates enough run time without oiled bearings.
These engines are remarkably tolerant of this situation. I cannot explain that.
