A few points of confusion:

--Shouldn't cavitation lead to a more significant drop in outlet pressure if that is the cause of the oil starvation, and you showed only a small difference in outlet pressures?

--If cavitation is happening then couldn't that metal debris be a cause of bearing failure? Moreover, shouldn't it show up in an engine oil test as metal in the oil?

--If this is the cause of oil starvation then couldn't this be replicated on a dyno or something, meaning, if it is just sustained rpms, and not sustained lateral g's or something else commonly related to track oil starvation, then couldn't it be replicated in a static environment? Is it common for oil starvation failure to happen, for instance, during a top speed run (ie long sustained rpms)?

it is one of the multiple reasons our engines are not good at high rpm's. This is awesome work and maybe just modifying the oil pickup will help a lot of people.
