Attention: TDR Forum Junkies 
i dont know if anything has really been posted about the new engine but i found these things interesting here is the link Ford's 2011 F-250/350 Super Duty Diesel Engine Tech Deep Dive - Will the Ford Diesel Power Stroke 6. 7-Liter V8 Hit 700 lb-ft of torque - Popular Mechanics
The test cycle is grueling and includes 1200 hours of continuous usage. They also run it for 6 hours straight at peak torque and for 3 hours at peak horsepower—and rev it to 4200 rpm even though the rev limit is set to 4000
i dont know about anyone else but thats not grueling by any means our engines are designed to run at full power under load all day since thats what they do with gensets and tractors, and they reved the engine up. i wanna know for how long you could spin mine to 10k and it would be fine provided you did it quick enough lets see it hold up to some sustained high rpm.
Of course this engine is computer-controlled, but to keep everything running optimally and cleanly, the new Power Stroke has two water pumps and two separate cooling circuits. One circuit cools the engine, while the other tends to the intercooler, the EGR cooler, and the driveline.
Controlling the air entering each combustion chamber are four pushrod-activated valves. Each valve gets its own pushrod and rocker, a design the engineers say makes for stiffer, more durable rockers than the usual forked design.
i read complicated and to me that equals problems. twice as many pushrods and rockers first they are probably smaller in order to fit in the block which means weaker. second twice as many parts more areas to fail.
two water pumps for cooling thats heavy and complicated which means they will fail more often as the trucks age.
what i dont understand is how can i have a 13 year old soild reliable fuel efficent clean burning truck that produces as much power as these trucks. mine is also simpler and easy to work on. why dont we focus on that instead i bet we reduce our carbon footprint if we just went with plan simple and efficent.
