I don't think that's correct, max hp and torque are reached at a much lower rpm vs the gas engineHere we go...I did not say they "have" to rev higher. The V6 must rev higher to produce V8 power. What the hell, is cylinder pressure wear? The original thread asked if a EcoB will be reliable as the 5.4l.
I have approximately 210,000kms on my 2015 ecoboost expedition which works out about 130,000miles. So far so good no engine problems. I think it would be good for at least another 100,000kms however the new ones are calling my name
The gap gets bigger as they are used, that’s what wears them out. The gap is set to allow the electrode to burn away and still maintain spark.
Dyno testing of the EcoB F150, the catalytic converters began to overheat. It was in high gear, on boost for long pulls(like, say towing a boat uphill). The HP/torque testing was done in 2nd gear, screaming like a banshee. Plenty of videos on Youtube.62,*** on my 2016 that I bought used in November 2017. Towed my boat with it for the first time last week, 540 miles round trip in a day (long story as to why). It's a 21' tritoon on a tandem trailer that's about 27' long overall. The ecoboost never needed to rev over 2700rpm to climb the steepest of hills.. Climbed most hills without downshifting, the boost pressure increased and it just happily chugged right up the hills at 1,800rpm @ 60mph.
My previous tow vehicle was a '14 Ram hemi with the 8spd and tow package, it regularly hit 3500rpm climbing hills.

YET...give it time.Yet half a million ecoboost F150s on the roads towing and hauling and no widespread cat convertor failures?
He hates any powertrain that isn't a 4.6 for some reason. The argument will never end if you don't walk away.

I keep it real. The 4.6l in the Expedition is pathetic, gutless and awful on gas to boot. However, it is a very reliable and long lasting engine. The dyno testing was impressive in the 3.5l EcoB. The long term life of this engine, is its biggest question.4.6, eh? No worries, I won't blow out a spark plug over it or anything. lol.![]()
Just for S's & G's, I've got to make an observation about vehicle "forums", ALL vehicle forums. As some know, I restore and collect vintage bikes.
As such, I used to buy/sell a LOT of bikes so over the years, I joined a LOT of forums and the 1 thing they ALL have in common is that everyone goes there when they have a problem.
IF there was any inherent issues with the EB powertrain, we would ALL know about it<LMAO>!!
JMHO......

I thought some of you who are wondering about the longevity of the 3.5 EB may be interested in an update to the post I made back on 3/7, on page 16 of this thread. Then I had 251k. Now, more than five months later I have 281, 872. I still haven't replaced any major components, at all. It still runs as well as it did at 100k. Still has plenty of power and, as you can see in the photo, it averaged over 20 mpg over a 350 mile run yesterday, part of which was spent driving old logging roads in a pine plantation, in 4 wheel drive. It may fall apart tomorrow but.....I doubt it.
Lots of guys with well over 200k. Doesn't mean nobody has had one break down, everyone treats vehicles differently. If you treat it well and maintain it, there's no reason it won't last.
