The problem isn't your statement. It's your factual backup that is in doubt. Anecdotal evidence is rarely correct, and in your case it appears to directly contradict what is known. In which case, most people would much rather rely on actual data.
Blown up eco-boosts? That's the first I've heard of it. Everything I've heard says that the water ingestion results in the engine going into limp-mode or open loop control until you reset it or take it to the dealership.
Can you link to a reputable source that shows an ecoboost has hydrolocked because of this issue? I'm having trouble finding any. I found some funny articles at Tundra net (toyota) and Gm Insider that have people 'guessing' what it might be, but that's like going to Stormfront to try to get unbiased political news......
I'm a frequent visitor on F150forum.com, there have been 4 or 5 over the past year on the 2009+ "2011 engines" sub forum that have puked and looking at the pictures that some of them posted it points to hydro-lock IMO. The one at the local ford garage was brought in for excessive oil usage, the cause, a cracked piston and a slightly bent rod with NO impact damage to the piston surface or head. The Owner of the truck had only one incident of the water ingestion issue about 6 months prior. I've been working on cars since I was 5 years old, use to be a ASE master certified mechanic before changing professions, and have built quite a few mud trucks so I KNOW what hydro-lock looks like as I've wrecked a few engine by drowning them. Simple math, over 1/2 cup of water in intercooler + quick uptake of said water + velocity of air throwing all the NON COMPRESSIBLE water to rear cylinders = A lot of strain on piston/rod combo and the water doesn't give. Hell, I've seen guys poor a whole cup+ of water out of there inter coolers and post pictures on that forum over the years.
To be fair, Fords F150 isn't the only one to accumulate water intercooler, most intercoolers that are set up like the way F-150's is mounted will build up water over time if there isn't much airflow through the cooler for extended periods of time in the right conditions. Where I live the problem seems to pop up more because you need to take a good 60+ mile drive to get to a bigger town get supplies and that 60 mile cruise on a foggy spring or fall morning is prime conditions for accumulating water and the first time you have to jump on the throttle in town guess what happens? I've had it happen twice on my supercharged V6 Thunderbird with inter cooler mounted in similar way, hasn't happened since I changed it out to a bottom draw style water cooled after cooler as there isn't a place for the water to accumulate then.
Yes, many people don't have the issue, but there is A LOT more than "100" out 400,000+ have had the issue. People that NEVER boot it to WOT don't see the issue, People that can the throttle a lot don't see the issue (clearing moisture before it builds), people that drive less than 60 miles each day/way don't see this issue. People that don't deal with frequent fog or high humidity never see the issue. People towing don't have an issue. Its only the people that have extended drives with a light throttle in the right conditions that have a chance of this issue popping up. Probably less than 5% of people that bought an F150 Eco-boost actually see those set of conditions.
I'm FAR from a ford hater (own a 10' Fusion, 12' F150 5.0) and FAR from a boosted 6 cylinder in a truck hater and just about purchased one myself if I hadn't taken I ride in one an experienced the issue first hand. I'm just talking about what I'VE experienced and what I've heard from my buddies about their own trucks. Does the problem happen frequently, HELL NO, does it happen YES. The 13' owner that had it happen is a 13' which came from the factory with the deflector installed already on the original style intercooler and has only had the Issue happen once. 2 others with 11's have only had 2-3 instances of the "issue" in 2 years of ownership. And the last poor fellow, who should REALLY get a car for his commute, has had it happen over a dozen times with his 12', even after the deflector was installed. His commute to work is 80 miles one way on 2 lane blacktop which builds water, why he drives a truck 160 miles a day as a commuter beats me?
