sho, any location you can mount is fine...but the water will be there any time a crankcase is not evacuating it in small steady amounts as soon as it enters.
The cooler, the better as both coalescing and condensation is used to separate these compounds.
The cleanside separator will do you no good without correcting the lack of evacuation......you must correct that (and a Ford dealer in the midwest with a 2013 that has had every TSB done and is still experiencing the issues has approval to install and test the RX system and monitor it's effectiveness, so watch for the results. It will be a long term test so I will report what I can as I get results from them).
bpd, you can easily test and see that the EB makes boost anytime your cruising. It is part of what makes this engine so powerful and responsive. The small turbos begin spooling up as soon as the throttle is opened. You can also put a flow gauge inline between the intake manifold vacuum port and the PCV valve that is integrated into the passenger side cam cover. You will see strong flow at idle only. Any time other than very light throttle, the flow ceases and thus the evacuation.
As to my qualifications and experience vs Livernoise, I dont question anything else they do, and do well. But I backed up all with easily verifiable facts and documentation. And yes, I show pictures from several makes of direct injection engines as well as actual EB engines. Since part of the issues the EB experiances are direct injection as a whole related, it is relevant to the discussion. Thats why I provided so much back up material to reference. The only thing the EB has different is the flaw in the PCV design, and with over 250 EB systems installed and in use over the past 3 months, every single end user has reported (the ones that have left feedback) all the issues have gone away.
The supercharger story is also directly related to their nit understanding proper crankcase evacuation and the issues related to it, and they are hardly alone. Most big known shops do not understand it...it is not taught anywhere any more so most just make assumptions. Look at LMR that is well known and respected. They delete the entire PCV system and allow all of these compounds to accumulate in the crankcase and just relive pressure. The example I gave with the top mount SC's is an example of that. One must first understand all the functions of the PCV system and all that it does. And I still want anyone here to tell me what this mix of gunk can do to help any part of an engine. This is the ONLY area we really disagree on, and they have never in the 4 years since we began this debate have ever given any actual examples other than opinions. I have a ton of respect for them in every other area. Now I will point out one more thing. With a lifetime of Championship (not going to a test and tune day) drag racing, we experience what most never do. You can still find one of our team/family at most every NHRA National event, and our experience with proper crankcase evacuation is shared with every winning team out there. All constantly evacuate the crankcase to save these engines and anyone at a race simply needs to walk through the pits and stop at any teams area and see in person. An these we change oil after every event. On the street, with extended oil change intervals, this is even more critical.
Weekend before last, Peter won both Stock and Super Stock, and this weekend we had 6,900 plus runs down LVMS breaking all records of the history of the track as far as race cars down the track, and next month is Bristol (the family puts on the most driver attended drag races in history):

The picture I showed of the piston is pour forged version. Here is the stock EB piston:

Not much difference in the top design.
And more ecoboost specific pictures:



Each above is a different EB engine with as little as 30k miles, and the most was at 70k miles. Then after manual cleaning:

Below is an actual EB CAC:

And finally,
if all we cared about was sales, we would just offer a can like everyone else and not design the complete systems that correct any shortcomings, and would not go into the intense technical details of all this...we would just sit back and sell cans. There is not a singe company in the world that does the R&D we do on such a wide variety of platforms. We purchase every can we see on the market, run the same tests, and dissect them for all to see.
And, Racor, Alfa Laval, etc. all have great systems....but for pretty pricey solutions. And all would have to be modified to correct the EB's flawed PCV system.
Look at all the oil analysis results of the EB's showing high levels of fuel. water, metals from wear.
And then the Ford endurance test. Watch the video. of the tear down. They never show the intake valves...only the underside of the cylinder heads up close. The EB engine is amazing, one of the best DI engines to date, but the PCV system flaw is not the engineers that designed the engines fault, those decisions are made by accounting, legal, and management that look at the bottom line only.
I am not here to force this on anyone. You buy your vehicles, and YOU decide how to care for them. If your fine with this gunk being ingested, 99% plus of the owners today never know it and are happy, so dont change a thing. This is only for those wanting to learn more and to better care for their engines.
We have been building turbo and supercharging systems for direct injection V6's for longer than the EB has been in production, and learn a ton by experience...were sharing that experience here with those that do want to learn...but we are not here to fight or have arguments about who is the "best"....only to share, provide actual verifiable facts, and give the resources to search and learn for your self.
Anyone can verify all I have claimed here, on your own vehicle easy enough.
And again, Livernoise is one of the best one stop shops in the US and does mods and tuning for many different brands as well. I send them non stop referral business and if I didn't believe they were among the best, I certainly would not continue doing so. They have one of the best equipped facilities in the country as well. I endorse them and trust in most all they do. This is the only area where we have disagreed and watch, I expect when it comes to the ecoboost they will come around as it has such severe issues with the PCV system.
So again, not here to fight, I don't compete in anyway with Livernoise, and those that follow us know we also endorse direct competitors that also have effective functioning catchcans, and that certainly gains us noting in sales, just the opposite.
