Default [PickupTrucks] Teardown Of Ford Ecoboost V6 Torture Tests

Quote:
Ford Motor Co. made some history over the weekend when it did a complete engine tear-down and inspection of a "torture tested" 3.5-liter EcoBoost twin-turbo V-6 used in the latest F-150 at the 2011 North American International Auto Show in Detroit.
What the Inside of a Tortured Ford EcoBoost V-6 Looks Like - PickupTrucks.com News

Compression loss on one cylinder (in the RINGS no less) and a crap ton of carbon build up, on a cherry picked (i know Ford said it was a random one, but get real) motor?...i'll stick with the conventional V8.

Im sure it was a random motor and if you read the article the engine went for more than 200,000 of the hardest miles possible and still put out stock HP and torque ratings.

Hell Im still surprised it was faster while towing than the 327 Chevy and the Hemi Dodge.

No. It was 'simulated' for 150,000 miles, not 200k. And pulling some logs isn't what i figure as the hardest work possible. It's not like it was pulling stumps

That vs the 5.3L Chevy isn't comparable, LARGE horsepower and torque difference. But the Ecoboost is significantly more expensive too. The Ecoboost is roughly the same price as the Chevy 6.2L, which would blow that Ecoboost out of the water (and only get 2mpg worse), but would be much more reliable too. Either way, loss of compresssion after that isn't something i would want to happen. If it can't make it to 200k, count me out.

The only really hard parts of their so called torture was pulling the racecar around the track at WOT and the baja race. Heck, i'd put either of my trucks up for the logging, and i'm confident they'd do it. It's no worse than construction. It's just how they presented it. Marketing.

I feel that was a pretty incredible test tit for tat. The engine held up great given it's complexity. It was actually 163,000(150K on a Dyno 13K real life trashing.

No, it didn't go 150k on a dyno. It was simulated on a rack with heating and cooling.

Just did some more research. The axle ratio on the Chevy was a 3.42, vs the Ford's 3.92..the Dodge was closer but i'm just proving my point that they really stacked it against the Chevy in several ways.

Honestly I'm surprized it held up as well as it did. New design, untested, being abused and mishandled the way it was, and it still made it's rated numbers afterwards?! This thing might be the first V6 Ford has made that is actually durable.

An LS7 would be in a serious world of hurt after the hell they put that V6 through. Don't kid yourself. It did amazingly well for having run the Baja 1000, among other torture tests.

That's normal. You do realize that carbon buildup starts accumulating on the piston crowns within, oh, say, 250 miles, right? You also realize that said carbon buildup is entirely harmless, right?

I was reading (on a Ford truck forum no less) an article about it that said they didn't buy it. They said it would be way too gutsy for Ford to disassemble that motor in front of the world. I'm skeptical too, but whatever.

We'll see how well these things really hold up when they get out in the real world, with idiots driving them.

Are those blocks aluminum or iron? An aluminum LS7 block would oval out its cylinder walls well before anything else major happened. Well, maybe except bending a pushrod but it could still run without you knowing it.
