how much power can the 6.7 make?
i am just curious to know if anyone knows how much power the 6.7 can safely make? i have heard that ford plans to keep this engine in its trucks for the long run, do you think we will see a power increase out of it in a couple of years, or is it pushing its limits with the new flash?

FWIW, I would be VERY surprised to see another flash update to the existing trucks in a similar manner to the 400/800 flash.
I'm pretty confident the 6.7L will see more power in the future, every other diesel engine has over it's livespan. But probably not for those of us already out here.

Are the axles and ring/pinion gearing still the only things that change on the heavier service medium duties than the regular super duties? Or is there a transmission change, or gearing change within the same case, in the bigger trucks?
The more power you generate the more fuel, air, and cooling capacity you need. I'd be curious as to what the limits are of the 6.7 also. Cooling would be pretty major - not sure if all of the extra cooling capacity would fit in the trucks or not. As pbruckne has alluded to in other posts - something has to give. What will be first?
That would be fun to be on the R/D team that pushes the limits on these engines to find where they do fail and how. I wonder how many engines Ford has blown up to find that out...

The PSD engines have always been used in trucks up to F-550s, and they have the exact same driveline as the F250-350 pickups with the exception of axles.
Different gearing in the axles, but that's about it. Back when the '08 6.4L was introduced, Mike Rowe could be seen in one particular video talking about how the cooling system of the F250 was designed to cool an F-550.

I for one could use a lot more power. Starting out at 6200 ft and going up from there I suffer from the Higher altitude loss seen during the "Fumble in the Rockies". With mountain passes in the area that are 10% grades or more they really sloooow down the 6.7 towing. And zero "engine brake" assistance also.
But otherwise a great truck and tons better than my 6.4.

I kinda agree here...I don't know about 250/400 but If an upgrade of say...550/1000 will only get you to around 150k,Then I'd be more than happy with the 400/800 flash and 250K.

400 HP is more than some semi trucks have. I've pulled the same grade as the "fumble" in the rockies at 20 MPH with the pedal on the floor before with a Kenworth and it's 435 HP 15.2L Caterpillar twin-turbo engine. That truck had a radiator that's much larger than what's found in a light truck like our Super Duties, and it overheated 2/3rds of the way up the hill!
I think it's downright amazing that pickup trucks are beginning to rival heavy duty trucks in power, even though they tow a fraction of the total weight.
Everyone wants to be able to go the speed limit or faster up some steep grades while towing heavy things. This just isn't a reasonable thing when you start to tow 10,000 lbs and over.
