A very interesting takeaway I got from this comprehensive video late into its runtime is that based on the test car data it appears the noted oil pressure drops from 50-60psi down to 20psi on certain turns happen at 6k rpm and above.
Further, that with at least one of the drivers who submitted analysis data they found that simply dropping into one higher gear on the turns where the pressure drops normally occurred to reduce the RPMs (by 800-1000rpm, say) pretty much eliminated the pressure drops on those turns.
Again, according to what they stated in the video above at 1hr, 14min in.
Someone please correct me if I have misunderstood what they were saying but this makes sense to me since the less your RPMs the less oil pressure you would need anyway at that given lesser RPM.
This isn't something billed by them as an actual solution to the problem but it would seem to be VERY valuable information for anyone who simply might want to play it safe(r) on turns that might concern them.
