Looks like oil starvation issue in the right handers solved

Just read the comments. Plain and simple, no need to spend ton of money on baffles, let alone accusumps.

Comment says 1 liter overfill. @900BRZ tried overfill (IIRC 1 quart, which is almost the same) and that didn't help much.

Before declaring the problem solved I would say we'd want to see a before and after comparison of oil pressure that shows the pressure drop without the overfill and doesn't have it anymore with the overfill.
It might be that in Laguna Seca conditions aren't right for the pressure drop people see on other tracks. Or something in the way he drives. Or his oil pressure gauge is different (as it barely shows any fluctuations not related to RPM which seems unreasonable).
He's also running SX2 tires (in 245/40R17) with fairly low camber (-2.3F/-1.5R) which might not generate enough lateral G's for the pressure drop to occur.

T3: 3rd gear, ~5000 rpm, flat
T4: 4th gear, ~5000 rpm, flat
T10: 4th gear, ~4600 rpm

That's very different from what Brian / @900BRZ used in his tests.

Additionally, 1:48.85 is a few seconds off the pace of what 900BRZ's "test driver" would do in the same car.

I am the driver in this video, as what Timurrr said, I mainly am using a higher gear, esp in T4 and T10 to mitigate the issue, along with the 1L overfill.

I am also not as quick as other 86 drivers, which also can contribute to a better oil pressure reading. This is good news to those who are more novice/intermediate level, and won't have to worry as much.

In short, no, the right hander issue is not solved, at all. However, you can mitigate issues with 1L overfill and staying a gear up.

Apparently @900BRZ already has a solution in hand based on his latest video?

I can't wait!! Looks like @900BRZ has had quite an adventure... replaced an engine too. It is hard to get proper attention when our numbers are so low, but very happy they are working on it. And what have we heard from the two auto companies... crickets!

looks to be an accusump setup. It adds complexity and failure points but pretty cheap insurance for those who regularly track their cars
