EcoBoost Makes Ward's 10 Best Engine List

It boils down to PSI on the piston top for any ICE

Small displacement crammed with big block amounts of air and fuel behaves like a big block, as the PSI force to the crank is in the same ball park as a big block. Know folks don't understand why their tiny displacement gets similar/same MPG towing same/similar trailer as a big V8...telling that they don't understand this crammed amount of fuel/air into a small cylinder thing...

Issues 'have been' blowing holes in the pistons, bending connecting rods, bending cranks, wearing out crank journals, blowing holes in cylinder walls and the biggie...keeping a small surface area block/head cool while producing big block amounts of power.

There just isn't enough surface area on these small displacement ICE's to manage the amounts of heat...unless expensive to design, test and build measures are taken

Part of the why there is a engine oil spray inside the block jetting to the bottom of the piston/rod/crank. Would assume the journal bearing dia & width is in the order of a big block's...and bet even larger, as that amount of power is spread over 4 journals or 6 journals vs 8 journals.

Minor stuff that will kill these small displacement ICE's quickly is engine oil PSI/GPH. If the oil film is lost and the journals go metal to metal too often...catastrophic failure very soon... A misfire one time too many on these small displacement with big block amounts of fuel/air can destroy itself in a hurry. Betcha they go into any of the levels of limp mode more easily/often than my big block

Duty cycle rating for towing heavy is way different than when using the same TV as a 'car'. Folks who compare racing vs towing miss that point and/or do NOT understand duty cycle rating

Still waiting for the used and rebuild market reports. As how much is left to rebuild is still a big question to me

Exact same thing can be said of diesels. My 6.6L put out a whooping 115hp then the factory decided to turbo it heavier oil jet cooled pistons, oil coolers etc and wow 135 hp! They later took the same engine and intercooled the intake air and got 200hp.

Then I come here and see, “no replacement for displacement” while they drive the same size engines putting out 400 hp. That comment to me means the person attempting to be an authority is yelling, “I AM EXTREMELY IGNORANT!” I watched it happen successfully on diesels and now I get to watch it on gas and see no reason why it wouldn’t work. I bought used and had a list of requirements but EB or v8 wasn’t on the list. Next time EB will be.
