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 slant helps the oil drain back to the sump better as g-forces go down.
I wouldn't do ramp unless I did wall at bottom of ramp with trap doors.

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.

^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?

Not sure I'd want to remove any windage trays. Probably there for a reason...?

Isn't it kind of moot after you put in another full scraper?

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.
