Focus RS
The issue of water pooling likely comes only from people who never push the car. Even on the Ecoboost F150's that had the problem, not everyone had the issues. I would venture to say that people who never towed or gave the truck some throttle are the ones that were more likely to have the issue. I can't see water building up to a significant amount if someone lets the car stretch its legs every now and then.
Like any other vehicle, performance driving is only one of the battery of tests an OEM puts the new car through. There are likely 10-20 FoRS's with over 100k miles on them sitting in a warehouse somewhere, partially torn apart by engineers for component inspection.

Problem seems to have been around a while, and is not the result of "our intercooler being too efficient"
Different car, dude. There's also this line:
So if the charge is cooled to ambient temperature, a sign of a good intercooler, the problem appears. That's my take as a person that did indeed take physics in university.
What does this have to do with humid areas? Those drivers live in an area where the dew point is equal to the ambient temperature for much of the time. This means condensation occurs more often causing more issues.
Yes, but its clear that ecoboost engines have been having this problem on models with "less efficient" intercoolers than what is found on the RS.
For instance, its also an issue on the Focus ST http://www.focusst.org/forum/focus-s...densation.html
I basically live in a rain forest and have never had a "condensation" issue with ether my stock intercooler or an ETS 3.5" on an evo.
Looks like some Ford trucks have been having this issue since before 2012. Ford released TSB 12-10-19, but some owners report it not fixing the issue http://www.f150forum.com/f70/trucks-...-issue-182785/
Seems like Ford knew, or should have known, this was an issue. But I guess you can believe that the "block off plate" is there because the intercooler is SUPER efficient.
Wonder why this is not an issue on Garrett intercoolers, I guess they are not efficient enough.

Did you bother to read your own link?
The car you reference isn't stock.
Further down:
Nothing in that link suggests it's a problem on the ST.
Perhaps you haven't had a problem because your intercooler isn't as efficient.
I'm running the large steeda/cpe intercooler.
Further down:
Worth taking a look at I'm running an open air filter from steeda at this time. The filter was dry last time I checked.
Perhaps you haven't had a problem because your intercooler isn't as efficient.
That's what the Ford engineers have attributed the problem to; an overly efficient intercooler. Given that they didn't change the design but just installed some plates to block air, it appears to be a legitimate explanation. If the problem was the design itself, you'd think they'd change the design itself.
Except Ford also tried the block off plate "fix" on the F150 and people report it still being a problem.
1. Check for DTC P0430. Is DTC P0430 present?
a. Yes - Replace the left bank catalytic converter assembly. Refer to Workshop Manual (WSM), Section 309-00. Proceed to Step 2.
b. No - Proceed to Step 2.
2. Is the Charge Air Cooler (CAC) equipped with an air deflector plate?
a. Yes - Proceed to Step 5.
b. No - Proceed to Step 3.
3. Install a new CAC, new air deflector plate, and original shield using new retaining pushpins. Refer to WSM, Section 303-12. Proceed to Step 4.
4. Reprogram the PCM to the latest calibration using IDS release 79.02A or higher. This new calibration is not included in the 2012.5 DVD. Calibration files may also be obtained at www.motorcraft.com.
5. Install a new CAC and the original air deflector plate and shield using new retaining pushpins. Refer WSM, Section 303-12.

Yea, the f150 has a 15" tall CAC and the inlet and outlet are all the way at the top. Like an ETS Evo intercooler, but flipped upside down and taller.
I just about fell out of my chair laughing as I read this because, "this never happens on Evo's." #ded

To recap.
Why does the Focus RS fmic require a "block off plate" and will condensation in the intercooler be an issue?
If yes, is there something about the ecoboost engine, or the intercooler design which causes more than normal condensation to form inside the intercooler.
Ford claims its because their fmic is just so damn efficient they had to tone it back. I am not so sure.
