IIRC I think I can get a bit more finger between my downpipe and pan. Close enough I coated the pans exterior to keep heat away. Before that I had the DP wrapped. Unless I'm remembering it wrong?
The stock pan actually requires the oil to flow back over a hump to make it back to the sump which is even worse than if it were flat. The hump is to clear the exhaust but last I checked the exhaust doesn't come close enough to the pan for that hump to be needed.
this is interesting, my sump doesnt have that hump...
The slant helps the oil drain back to the sump better as g-forces go down.
It also allows the oil to get to the thin end easier as G-forces go up.
I wouldn't do ramp unless I did wall at bottom of ramp with trap doors.

I got ideas!
Looks like you could leave outside of pan as is, remove that "scraper",
and add an internal ramp, with or without a wall and trap doors
at the bottom.
2 cents here. Tuff has been called out on that before, and I agree, the graph is not a racefab but a stock pan. I have NEVER seen 20's in my RF pan, doing what I do, so I have a very hard time especially since the graph doesn't exactly line up - at one point the stock pan goes into 20's and the tuff pan pressure goes...up? Odd is all. If you look back I've shown install, video, and data proving it's capability, but here's some more. I've added throttle and lat G's for reference. The lowest point on my fastest lap of that race was in turns 4-5 which is a notorious off camber right that holds for awhile because of how slow you have to come into it. So your pan is not only fighting G's, but is actually tilted that direction. I actually went off there in lap 7 because I didn't slow enough. So the lowest I've officially seen is 57, at part throttle looks like. That's good in my book for sub 1k solutions.
But I also agree with all the rest, lets keep innovating and making it better, stronger, faster.
^Balrok, what is your max Gs in those turns? Looks like around 1.12 according to the graph, or am I reading that wrong?
On that turn ya, about 1.2 peak in the next two turns because they're on-camber, longer, and ironically more oil pressure. At RA last year I was seeing 1.3's. This was Sunday's race (not the video), which was 26 f*n laps long. Lost tires in that lap and I was running on fumes when I passed the checkered lol. Looks like I dropped to a 1:25 with my off on lap 7 and the rest were consistent in the 1:21's. I expect 1:18's peak and averaging 1:19's later this year. This was my shakedown event so expect to see more later.

what's the quick rundown on your setup? tires, aero? other oil mods?

ST3 setup, so a little over 300whp, 275 R1S's, splitter/****/diffuser, same oil mods in my other thread I've been running for several years now - Kiggly, Tomei scraper, RF pan, fans for coolers, DOM50. 71HTA with all stock lines. It's a great combo. I also put a TCase bolt in the oil pan drain because the mag is WAY bigger, threads are the same.
The stock pan actually requires the oil to flow back over a hump to make it back to the sump which is even worse than if it were flat. The hump is to clear the exhaust but last I checked the exhaust doesn't come close enough to the pan for that hump to be needed.
Anyone think there is any downside to removing what I assume is the stock oil scraper,
to make a ramp down shallow end, assuming you are using Tomei?
Isn't it kind of moot after you put in another full scraper?
No idea. That's beyond my pay grade. a scraper helps keep oil off the crank, I guess... but seems like you want oil to have an undisturbed flow back to the sump, so would want a windage tray there. Maybe.
That's what I was wondering. I guess more of a "wall", from moving the floor upward, would help prevent oil from moving that way?

^Off to post a for sale thread on a never installed modified pan.
Put me down for version 2.0
Something that I think would be simple to include in any pan would be for the turbo oil return to feed right into the area where the pickup is. Metal tube down into the sump. Same potentially for the oil pressure relief hole on the bottom of the inside of the front case.
