Not often do you see a product get developed with so much transparency and details of the process. Love it. Huge kudos here and can't wait to see how the testing goes, Skip. Keep on keeping on
Skip,
The whole process has been excitng to watch and the bench test of the UIDS is awesome. Can’t wait for the test results to be completed with installation in “Sally”
To echo others, I love seeing the details. No such thing as TMI !
(Edit: and your testing rig is brilliant!)
I'd be interested in your various test conditions. What do you think the worst case conditions would be?
Maybe cold oil, so it's viscous, but with slow speed switchbacks? Slow speed means not alot of G's to slosh the oil back and forth. Maybe you already tested shallow switchbacks (sloshing) on your test stand?
What do you think is the most likely failure mode? Can the ***** get stuck? (From grit or RTV in oilpan.) What happens if they do? I think then it would only pull from one side?
I know you've definitely thought this all through, I'm just very curious about your testing plans!

Thanks guys !!
No worry's on cold viscous oil !
The oil screens on the uids will protect against the bigger debris, the ball guides were given a lot of cleàrance to keep from sticking from small stuff, and lots of hours went into the details of this to get it perfect.George came up with a brilliant self-centering seat to meet the needs of the loose clearances of the *****/guides... The devil is in the details !!
Sally is ready for her new jewelry and it will be fun testing/ driving around, and a whole lot less tireing than all the previous work.

Not just to read oil pressure, but to read oil pressure under a lot of different scenarios e.g engine angles, oil level, RPM ect.
By using the cutaway, I can control the angle of the engine (tilting it ) and also control how much oil is in the sump e.g. 1 qt , 2 qt , 3 qt , ect. I can read the oil pressure and also the suction pressure of the oil "intake" .saves a lot of time..
Interesting note: With the oil pick-ups of the UIDS v2.2 located at the sides, the engine can lay completely on it's side (vertical 2 G's) and still maintain oil pressure with only 2 qts oil in the sump.
Also to keep having to heat the oil to get to operating viscosity, I used Glycol for a flow medium, it has a viscosity of 17 cst which is the same viscosity as 5w-50 at 100C ( 212F)..
If I had a couple million $$$ for R&D ,,,I would use one of these for testing the UIDS V2.2 ..This was developed by Porsche for sump testing AFTER the M96 was discontinued !!!
This is insane reminds me when I was at Valvoline on product development at the engine lab. Skip FYI yes at that viscosity cst
at 100 glicol has the viscosity of an sae 50 oil, to know the low number you have to run cold crank and etc. I m willing to bet is not a 5w. Anyway I’m not tracking my car but I want to get this thing. Also if you don’t mind please monitor oil temp to see what it does. On my car and I don’t know if the previous owner installed a lot temp thermostat, now that the rads are super clean and I am running close to 33 percent af/coolant even when I’m going to 140 and really running it hard the water temp is between the 1 and the 8. Next I’m going to see if a can get a bottle of redline water wetter.

This is rather completely awesome. This is the sort of test rig that I would have used. One note: completely on it's side is not a position that any driver ever wants to be in! 2G of lateral acceleration isn't completely on the side, it's actually only 63 degrees from horizontal (inverse tangent of 2 is 63.4).
Did you test cornering and braking accelerations/tilting? I think the worst case is braking hard into a right hand turn, that would be tilting the engine 45 degrees left to right and 45 degrees front to back.

So that way the test rig is easier to mechanize, build and control if the freedom of movement is dynamically limited by stops to replicate approximately 1.5G in 2 dimensions and have a total range of motion of 90 degrees? Skip could have a static stop for one plane testing at 60 degrees for max limit load test of 2G?

So, completely on it's side (90*) is 27* more than 2 G's?
Hard braking and right turn is "worst case" for the centrally located pick-ups, but the dual pick-ups of the UIDS v2.2 actually LOVES this scenario..

Somebody's not sleeping to get these tests done this fast. In my industry, if you know you'll have results in a day, you tell people you'll be done in a week. 3 days, 2 weeks. etc. Then you put the data out a day or 2 before commitment and everyone is really happy!
Dead stopped on Death Hill, nose up, full launch = Pass
High speed cornering on Clover-leaf i22-i65 = Pass

This is going to be fun!
The UIDS install was so easy and fit like a glove. Just 2 bolts for the flange tube, push up the UIDS onto the flange and install the (13) 6mm bolts.
I pushed myself a bit to get the testing done, I was really tired but wanted to get finished a bask for a few days before next step, but George needed a play-by-play of the testing so I figured I would go ahead let y'all know also. Now I'll take a few days and bask, just driving around to see if I can think of another test besides "Track Testing"..
BTW :: all these tests were done with the oil level at MIN (1 qt low) on purpose to see how good it was...( Pass)
