“Racers have already tested this type o ball-valve and concluded it does not work when you are continuously cornering” (Nick L- the man, the legend...[in his own mind])
^^^Must be speaking of all the Porsche oval track cars...
Look, at least give them a F'in chance to provide the data, then have a healthy debate.....Good grief, we all are the beneficiaries to the entire enterprise....cheer them on!
I honestly wish your criticism was coherent, you might actually help us all find a solution.
He owns it, but yeah i know he hasen't built it. Sorry for my wording, I will polish my english better so that the grammatical officers here will be happy.
Geroge, the big problem with my input is that it usually does not go inline with the 'big boys' opinion....I'm an engineer and calculate/investigate/test to find my solutions, I don't search for it on the internet. This causes people to mainly ridicule me over and over and over(case in point PT3).....I'm not that interested to put hours and hours to help to just face that same shlt.
Check the 'oil instability thread', +700 post to find out that I was correct that changing scavenge pumps and filling oil full would help. I didn't find that solution on any forum, that's engineering. And nicely not a single 'thank you' for my work.
Good luck with your product...and if you read my last post you will find I gave you some key things to check.
Nick, as I said to you in the IMSB threat. I appreciate your opinion. But sometimes I can't figure out what your intentions are. Further, there is no doubt in my mind that as a 996 owner, you most certainly care about your car.
Do me a favor and take a look at your comments that set of this current fist fight. What did you think was going to happen? You attacked a product and more importantly, don't offer any solutions? How else do you innovate without solutions?
Stop being the martyr and help us find solutions. We are wasting too much time with these freeking fist fights.

Nick_L when I was younger I used to be amazed at what Engineers knew, as I got older I'm amazed at what engineers DON'T KNOW.
As a 45 year Dealership Technician, and an Amature Racer/Designer, I have spent my life fixing things engineers F88ked-up on. Your Mulligan count here is way too high..(plus your attitude is repulsive)
I do not intend to follow ANY of your opinions, advice, theories, or "help"..

No need to start from scratch, they did a good job ( but not as good as it could have been) but just stopped improving it 20 years ago..and moved on to new designs...( where they are making new mistakes, or old mistakes in a new way)

GTFOH with that ****. This is the "Racers" that your were referring to that have proved MY design doesn't work ? Testing in a plastic tub with a drill?
The problems they encountered in the "tests" are not present in the UIDS v2.2 . Even though the design is similar to the Christen Valve for Acrobatic Airplanes, it is not identical and was not based on that valve.
These issues were fixed by using a solid pin between the ***** instead of a spring, and a brilliant self centering seat by George that seats at ANY angle above horizontal 0 degrees.
Your opinion is not welcome here.in my thread, if you want to address Zbomb, do so in his thread or start your own..
Skip, how much more oil do you think the UAOS can handle. Can't remember if Chris said he ran an extra 2 or 3 quarts?
I remember Chris said he ran 2 quarts overfull on the wet sump race engine with "no AOS/CCV system."
I think the UAOS with Track Drain can handle 1-2 quarts overfull , but needs to be carefully tested.
I think I will build a "Special Accumulator and sensor/harness" for testing the limits of the UAOS, if Zbomb will put in on and do the tests.
If I owned the car, I would just add a pint at a time untill I saw signs that it had reached the limits, then back off a little ,but on someone elses car, I would be more cautious and build a special test Accumulator/sensor/harness as an added measure.

Sent the file off to one of those online Laser metal cutting places that offer quick services for the Horizontal Baffle Plate . I should receive it in a few days and will keep the thread updated.here is a JPEG pic for the Baffle Plate.
In the meantime I have been driving Sally around performing the same test as before over and over (except the "Toes of the Dragon Test"), just get a good feel for it , plus she is my daily ride...
This is not an opinion, it’s fact, so I guess it’s ok to post?
This is what the forces look like in your valve. What happens is that when there is flow you have a differential pressure(P2-P1) across the closed ball. This pressure(force F1) will push the ball valve closed. Pressure P1 will decrease as the oil flow rate goes up, increasing force F1.
The Christen is tuned for the aviation engines it is used in so that the valve is normally sucked closed and only switched when it sucks air. You don’t want it to flapp around just because of turbulence. When it sucks air the differential pressures reduces to almost zero and the valve is free to move according to gravity.

Here is a picture to show you the forces.
Like I said, your thoughts are not welcome or needed here. You have ZERO credibility with your many Mulligans. I take offence to you using our drawings to illustrate your "negative thoughts"..
The UIDS v2.2 has already PASSED these tests, and I drive it every day. IF you don't cease and desist , one of us will get banned or this thread will get shut down, ( or I will shut it off) ,,because it will get ugly !!!
