Thank you 🙂

Windage tray you mean in a sump? It is to keep oil in a botom of the sump. More crank case pressure is always there when you make boost and it goes in to the head through oil return galeries, in different direction than oil that wants to return, so at some point it can push returning oil back to head and keep that oil all up resulting in empty sump. Thing that is a little hard to check. Sump design that you showed, good idea to increase volume, but I do not see any support for cornering that I think is bigest problem with oem sump.

Also, does 4e engines has oil return from head problem? I noticed that when I drive longer at high rpm, breather spits some good ammount of oil. Thinking about making additional port straight from head, intake side and down to block or sump..

Tooday made some mods to oil sump and done a simple test, compaired oem sump and new modified by filling with watter and mooving in my hands. Oem sump compaired to new one looks so bad controling liquid level in pickup location, I am thinking, maybe that was my bigest issue. I drove hard few times in a race track.

When I built this engine everything was measured and in spec, crankshaft is still in spec right now after all this. About oil grade, maybe 10w60 is too thick, but most performance engine builders go with at least one step thicker oil, mostly because oil gets warmer and at the same time thiner in high loads, so I think it is not a bad idea to go one step thicker, of cours oil cooler would be good idea too.. do not have any at the moment.
