@Siluck2 Has an early pan he might be able to speak to. I would also have one but new shop is taking longer and costing more than we'd hoped. So having to put some things on hold for now.

One more test day of data collection and i'll be ready to publically publish the results!
Based on my data my oil pressure improved by a tad 190% when switching to dry sump. I'd expect Mr. SVT's pan to improve on RF's but not to that extent. The big concerns usually are OEM or it leaks without a whole tube of sealant, and fitment cause there's only so many places to extend the pan into without running into something. Didn't know you were making parts man lol.
curious how much of an improvement there could be on the pan...
Here is a sneak peak - it's my first revision of the oil pan with oil pressure overlay.
Note - It's a Right-hand track. The final corner is over 1.0G for 8 seconds and it maintains stable (only 10psi dip right at the end) oil pressure.

Dry sump is the ultimate and something I'm going to recommend for customer's who are circuit racing.
But my solution will be perfect for club level and track-day enthusiasts, currently there is nothing on the market that gives suitable results.
(Note: Yes Racefab/AMS/Moroso is better than OEM, but my pan will be better than all of those).

I have Moroso and Racefab data waaaay back in this thread, may not be apples to apples but if you didn't test either of those it could give some baseline.
Yup built off the OEM Evo 9 oil pan for excellent fitment.
Eventually will likely go to a full fabricated pan, but that will be a later version.

I've got both Moroso and Racefab data off customer's Evo's. If you're happy to send me some data, I would love that.
The more data the better!
Pretty solid pressure all the way thru T10, Ive seen how much it drops away with a stock pan and your lucky to see 40psi there lol. 1:14 isnt sniffing round either so not like your taking it easy. Theres only 1 concerning bit right on the exit when you go to full throttle the oil pressure dips momentarily while your accelerating and you get down to around 60psi at about 6300rpm. General rule of thumb is you want at least 10psi for every 1000rpm and oil pressure should not be dropping while under acceleration or youll give the data guy a heart attack lol, This wouldnt be too healthy to do lap after lap id imagine. I guess could mitigate it by short shifting mid corner and getting the RPM lower. Still probably the best wet pan oil pressure ive seen through that corner on an evo.
Are there any other mods e.g kiggly HLA installed or anything? whats the capacity of the pan?
I think that old school mentality of 10psi/1000rpm doesnt really apply to our cars. At least Ive never logged that attitude and its more like it jumps to 70-80psi and just stays there unless its dipping due to right turns. In my car its a ~10psi dip on left turns but pretty much always just stays the same.
Because we're a regulated system once we get the pump rpm high enough to make the flow and pressure exceed the regulators bypass then the system is just going to try and hit that target. And at least in my case without Oil Squirters and Balance shaft, it hits the regulator pressure pretty quick.
On Mikes car, dipping "only" 10psi for a moment and at the end of the turn isnt to concerning to me though I do wonder whats causing it. I wonder if theres any kind of acceleration effect on the fluid weight or in the regulator that causes a spike change then quick recovery.

It may even be due to where the sensor is picking up its reading from even? Mind you if it was caused by acceleration youd expect to see it on every corner exit would you?
I was more concerned regarding the RPM going up and oil pressure going down trend for that second.
The video was taken from our first revision of the pan.
The very small dip in oil pressure at the end of the sweeper (Turn-6) would have been oil surge, but it immediately recovered.
Please see the two logs below. This is the typical performance of a wet-sump at Hampton Downs, with pressure going to 30-40psi for a very extended period of time.
Also you'll notice that pressure drops through T1, T2 and T4 is normal, as these are right-hand corners.
With my kit, there are no oil pressure drops there. So you could safely say this Infinite Evo oil pan reduces oil surge by 90+ %.
This in turn will extend the life of the engine and oil pump!
The Sweeper at Hampton Downs (Turn 6) is extremely hard to get perfect without a dry sump.
It's 8 seconds of 1.0+ Lateral-G. This is why it's an engine killer (As you've seen before Brad!).
And then you've got to deal with oil getting pushed into the catch can also, which reduces the oil in the pan.

All of that is bang on, I only had my Extended baffled wetsump for a couple of months before going drysump so dont think i have any data to compare. (It was from that fab place in drury Mike cant remember the name of it, BNR Engineering i think?) But i dont remember it being as stable as youve got there you always saw some tapering off still. Accusump was even worse.
Was that video shot at a downforce day? pretty cool with the cones out so you run the right lines and stuff
