This has been brought over from the "oil pressure instability thread" that Zbomb has going so George can post updates and such. If you want to read a lot about oil pressure drops and instability, I would suggest you read the entire thread. Lots of good info in there that can bring you up to speed on the subject.
Default Yes, It's got ***** !!!!Ok, I got the green light from my partner to share some info of what we have been working on for many many months. ( since I had already kinda let the cat out of the bag in a recent post).This is the third version on the same concept that I believe will solve the oil pressure drops on lateral G-force turns that I have seen first hand on the street with street tires in moderate turns, and what Zbomb and others are seeing on the track with great data to follow.
The Ultimate Integrated Dry Sump Version 2.2 (UIDS V2.2) takes a systematic redesign of the sump to address the shortfalls of the factory Integrated Dry Sump and of the currently available deep sumps that pick up oil from the center of the sump. The UIDS V2.2 uses a G-Force sensitive flow control valve to direct the oil pickup to the lateral side of the sump where the oil goes under G-Force.
The "Heart" of the system is the "Novel G-Force sensitive flow valve" that is robust and simple in construction, but is highly sophisticated and technical in design. This is the part that make this concept possible.
What sets this apart is the dual pickups that are located at the left and right of the sump and is where the oil will be on lateral turns, and can deliver oil even at G-Forces of over 2g. The G-force sensitive flow valve has rolling steel ***** (Tungsten) that follow the oil in the same lateral direction under the same G-force and changes the pick-ups..
We have done bench work and flow bench tests, 3D printed prototypes, but are still a month or more from actual in car tests. (sorry Zbomb), but have been working on this since well into last year.(this kind of stuff takes time)The UIDS V2.2 should need no Accusump to work.
Before anyone asks, the cost analysis of the time on the 100k CNC machine to make UIDS V2.2 parts has not yet been done so price prediction is not available, but I think the product will be well worth the cost and multiple times less that a Dry Sump setup and much easier install and cleaner.

Thank you for sharing. I look forward to seeing the testing results. I love my ultimate AOS so far. I'm hoping this will be the solution that will allow me to track my 996 as hard as my M3 worry free.
This post was also brought over from the "oil pressure instability" thread with an update of the progress.
I have never understood why the "3.4 X51 with the dual stage scavenge pump" was never offered for the US market. Possibly because of emissions reasons with the camshaft profile or DME tune? OR because it had only 1 cam position sensor? Anyway , The 996.2 X51 did NOT have the Dual Scavenge Pump on bank 2 head ,contrary to what many people believe. Porsche did state in Technical Training Class P10W that the new design of the 996.2 head had better drain bank to the single stage scavenge pump and felt the dual stage scavenge pump wasn't necessary. ( This needs "real data" to support or deny) I have always felt the dual stage scavenge pump was a big help on the 3.4 996.1 and would even help on the 996.2 3.6 engines.( it certainly wouldn't hurt)
The Porsche Aftermarket (especially in the US) is a lot tougher than most everyone thinks.
Back in the early 80's on my racing cars,(setting World Records), I had many many innovations/Inventions that were not able to enjoy commercialism, even though they worked beautifully . Sometimes the market is limited, just not ready for the Innovation/Invention, or just doesn't like/support it , or think it necessary.
LN Engineering had reproduced the Dual Stage Scavenge Pump for the market, as shown in previous posts here, but the market has not supported the product very well as sales were lacking. And Martins Dual Stage Scavenge Pump seems like a well made product also that I believe would help both the 996.1 3.4 and the 3.6 996.2 , but if the market doesn't support it, I'm not sure how long it will be available.
The UAOS doesn't have a big profit margin , but is enough to sustain as sales are consistent. Even though it is a superior product to the Factory AOS sytem , it has a warning system to warn of diaphragm failure, and eliminates the labor intense procedure of the replacing the AOS every 3 years. It is Superior to the Motorsport AOS in that it cost about half of the 996.1 Motorsport AOS, comes with necessary modified hoses, moves the diaphragm to a very accessible location, and with the Extreme Track Duty Auto Drain accessory, provides an addition drain back to the sump to keep oil levels higher in the sump. But I keep seeing people buy the Factory design and installing them , so the "market " actually hurts itself by not supporting superior products.
I am an Enthusiast at heart, with only 1 product to offer at this time, the UAOS, but I am on the verge of crossing the line to Vender status. Being a paying member I can only post 1 product for sale, but I'm not sure if I can continue on my current path to provide support, info, and products once I have other products for sale .
Just an update on the UIDS V2.2 " THE VISION IS COMING TO LIFE !!! "
I will start a new thread for the UIDS v2.2 (if allowed) to continue updating the progress.
Thank you for sharing. I look forward to seeing the testing results. I love my ultimate AOS so far. I'm hoping this will be the solution that will allow me to track my 996 as hard as my M3 worry free.
Can't wait Skip. I know how much effort you and George have put into solidifying the platform, not just for street use, but also for my use haha. When it comes to the capability of the platform we both like so much, from a chassis standpoint, for the money - it is really hard to beat and I am reminded of that as I'm getting pass by's from cars many years newer costing 10's of thousands of dollars more - this is a VERY common occurrence. My car sees 1.5G or cornering and 1.2 G of braking, all the time.
You have developed already what in my opinion is the most important engine mod I currently have, the UAOS with drain back and I commend you and George for now directing your efforts in what for me is the gaping hole in our very expensive engines reliability on track, maintaining a consistent and reliable supply of oil under all conditions.
I wish both of you guys the best of luck, and if you need any support from me, just say the word.
This is fantastic and super stoked to see the in car test data and how this develops. First UAOS and now UIDS Given the location of the UIDS the install should be a breeze in comparison to the UAOS too. It may be time for a new name for your web site. May I suggest UF6S = Ultimate Flat 6 Solutions

Thanks guys !! I need the positive Karma !!
Zbomb ; Thanks man, I will give it a good "shakedown" on my car with some oil pressure monitoring equipment , driving as hard as "I" can to see how it performs. I can't wait !! Then if it passes all my tests, we will see what it can do with a "real driver" manning the controls...
808Bill :: This is not a sandwich, it is a complete sump system that replaces everything on the bottom of the engine, even the oil pick-up tube and swirl pots.

Thanks man !! Yes, will be very easy to install. ...UF6S kinda catchy, I like it ...And it keeps with the 4 letter theme...lol
