The 6 EB has to work harder in the sense that there are greater combustion forces within the engine because of the boost. Like a diesel, the cylinders, connecting rods, crankshaft, related bearings are designed with greater strength on a EB.
Your claim is insignificant, because the similar power outputs of both engines are distributed through six piston/conrod assemblies in the Eco but are easier on the equally-stout *eight* piston/conrod assemblies in the V8.

I only have a minute, my popcorn is almost ready!
Actually, since both engines are designed and built by the same folks, and are both modern and newer designs.....it’s incredibly likely that they are both built to the same goals for longevity and both have the same robustness based on expected cylinder pressures in each case.
But, don’t let that slow anyone down from claiming one of these motors is sooo much better or stouter than the other.

Your link is interesting but it does not support what you said...
So you would bolt a supercharger onto the 5.0 without changing the pistons, etc.?
Personally, I find I cannot completely utilize the standard F150 Coyote's 385HP as it is, and since most of my hotrodding days are behind me and since my present interests involve tugging very small travel trailers through the Eleven Western, my truck is near-perfect as it sits.

Get a whirly pop...so much better

1. I care.
2. I'm genuinely curious
How well it is maintained is important, but let's assume both were properly maintained.
Which is going to last longer with the littlest maintenance required and less maintenance cost

I have 80,000+ miles on my eco...still runs great and I have no worries about the next 80,000 miles.

On paper from a Reliability Engineering stand point:
Failures/defects are proportional to the number of parts in a mechanical system or electronic circuit.
Add to this, moving parts subjected to intense heat and high rotational rpm typically increases individual component MTTF rates.
Lets hope Ford did their longevity homework on the ecoboost engines.
Oh wait, they can't even engineer a door lock that won't freeze up!
