"... remove the contaminant laden vapors from the crankcase and this allows them time to settle and mix with engine oil accelerating wear and eventual failure. So it is critical to to use a system that provides full time evacuation suction."
What he is saying is, the blow-by gas should not be allowed to mix with engine oil. Thus, suction is required. A pressure below atmospheric is PCV , PCV = suction. "It is critical to use a system that provides full time evacuation" This mirrors exactly what I said about creating a pressure drop inside the crankcase using the air filter and pcv system, it is the only way to pull a suction on the crankcase to remove those 'laden vapors'. Otherwise it will cause "Eventual failure" and "accelerating wear".
If you check the link it will show the Turbonetics solution which also mirrors the pictures I Posted in this and other threads for PCV route, to draw suction PCV On the crankcase which can maintain engine health and oil quality. PCV is absolutely necessary, otherwise "eventual failure" and "accelerating wear" is your future.
As an academic, you should know that you have to cite your sources when using them. in this case that would be links to the sources you are quoting not post some hard to read txt copy of it. Posting screen shots of bits of something as proof and hiding the rest is just playing games. In this case, you keep leaving out the part that shows what their method actually is. Yet, yet you keep saying it proves you are correct. That'd get you a failing grade if you turned in such crap as a student.
I'll post the full info so everyone can see how full of crap you are.
Their method is a sealed catch can with 2 suction hoses. 1 hose goes to the intake and functions like a normal PCV using intake vacuum. 1 hose goes to the piping before the turbo. both have check valves so the intake hose doesn't allow boost to the catch can and the intake hose doesn't allow vacuum to suck from the intake plumbing.
Here's the part it you were hiding. The post says this,
As you can see, this type of system uses the intake manifold vacuum for evacuation suction when in non-boost operation, and when pressure is detected the primary checkvalve closes, and the secondary one opens switching to the suction created from the Venturi effect of incoming air passing a fitting installed into the turbo inlet. The check valves will automatically default to the strongest suction source no matter the operating mode providing full time evacuation and preventing any boost from entering the crankcase.
The bold emphasis is mine. Venturi effect, not intake restriction. Why were you trying to hid that? Because you claimed that the intake needs to be restrictive so it has a vacuum as the rpm's build? Because you claimed a freer flowing intake would ruin the PCV function? Nothing posted there actually backs up either of those claims, and it would appear you knew it and chose to try and hide it.
What was suggested is similar to using the exhaust for scavenging, the fittings welded into the exhaust pipes creates a venturi effect.
I was never the type to follow typical study plans. I sort of forged my own path by taking courses I was interested in. For example I took inorganic chemistry as an elective instead of say, roman history. Now, I didn't take every math the college offers, for example to this day I still don't know what liberal arts mathematics is, it uses some kind of symbols. From 2010 to covid I was a math tutor and from time to time students would bring that **** in and I would just shake my head. But almost anything else is fair game, with a PDE You can solve real world problems especially when they resemble one of the fundamental models such as wave equation or darcy's law or laplace equation. And as you said, just knowing calc and diff EQ goes a long way to using provided engineering toolbox, and computer aided modelling such as matlab. And then there is actually opening the mechanics book and learning what a stress tensor is and being able to equate the different types of flow such as steady flow to real-world situations such as a horsepower graph which peaks to some number and holds there, like many turbo power output graphs will (I aspire towards steady flow situations because you get a good idea of what the intercooler is capable of handling in the given setup, which reflects into its usage, application, ultimate reliability).
That's a whole lot of word salad, friend.
Do you have an example of a tuner-related problem you came across that you solved with a PDE? I'd love to see the math/matlab code.
Glad you like it...probably the most boring thread i have wasted my time on in the past 20+ years...i fell asleep 4 times while reading it...
At least when Evil-Twin went on and on, you could understand it because it made good sense...
This was back before widebands were available to general hobbyist level (I didn't have one, they are too expensive in 2003)
Used it to tune my twin turbo small block 355 in 2003, also avail free for download and for a few years I supported countless users and eventually filled my inbox with more inquires than I could handle.
It took aftermarket almost 20 years to eventually offer wideband auto tuning capability similar to what I had written as a college drop out.
I've been doing 'this' for a long time, and in hundred thousands posts across 25 forums I've never been wrong, try to find one
Eventually the things I write here and elsewhere will become common knowledge. Like the Earth revolves around the sun kind of things. But right now it is a new thing wearing terrifying masks and everybody just wants to burn the witch and go back to their routines. You can hide all you want but eventually you must face the data, raw terrific data showing everything I said is true.
When people pretend that dry sump engines do not exist and fail to comprehend what its doing is /baffles me completely when they try to argue on the internet about those ideals which are clearly in practice
So now you think a narrowband can be used as a wideband and tune any reasonable fuel ratio. Is that something else people should eventually realize is common knowledge?
I've tried home grown self-tuning spreadsheets using both narrowband and wideband O2 sensors. They worked pretty badly and I can get there quicker by applying 1/2 of the fuel trim error and then hand tweaking the table. The problems with any narrowband "easy" solution are that you have to tune at stoichiometric and then the solution doesn't know how to blend or when it shouldn't be adjusting a cell.
Also, Holley always had a self-tuning option on the Commander to give it wideband fuel self tuning so claiming you were an innovator is a big stretch, and rather pathetic. A cheapskate who didn't want to pay for the upgraded model would be a more appropriate description.

I don't have to look far, at all. Pretty sad ignoring my previous post just to go on about how you are so special again.

My goodness!! You may be correct on many things, and maybe not. But when you say you've posted across 25 different forums, hundreds of thousands of times, and NEVER been wrong?? Then add "try to find one." WOW! Tells me pretty much all I need to know. You're the only guy I've ever heard of that's never been wrong. I can't speak for others, but I've made mistakes, and been wrong. The only guys I've ever known who say they've never made a mistake, or been wrong (same thing-different terminology) have been some of the most incompetent, arrogant people I've ever had the unfortunate opportunity to meet. Usually, an intelligent person doesn't need to stand on a soapbox pounding their chest, crowing about how smart they are. I've found that most times, a persons intelligence and competence levels will speak for themselves, with no need to advertise it. Good luck to you....
