I was measuring oil pressure and during one turn it consistently dropped to ~20psi. I'm assuming because of oil moving away from the pickup. Hard to see from the video - 3 clips of the same corner back to back, but you can see the gauge drop when I turn left.
Go to the n55 section on s p o o l s t r e e t and look at the accusump thread. Tons of discussion on the oil pressure drop and trying to fix it.
