Even if it's not completely blocked, at sustained high RPM with all those factors that's enough to give you enough starvation to spin your bearings.

There was a guy who tracked extensively /owned a shop in South America (Peru?) on this forum who was blowing 13-16 motors left and right until he went to a larger pickup tube. The thread should be on this site, he had some good data points.
Fair possibility. But I would think that with the pickup designed to combat loss of pressure they would've considered cavitation as well...

And considering the ECM monitors oil pressure, the oil pressure warning light would've (should've) illuminated had there been a loss of pressure from cavitation or some other issue.

My 13 is tracked extensively...still on original engine....
