Dyno: 11-16 vs 17-18
I have searched both here and on the web in general and have not found dyno charts from the current and prior version of the 6.2 engine in its stock form. Everyone keeps talking about how much livelier the 17+ version is - could the the engine alone or partly due to the transmission as well, but it would be interesting to see hp/torque at the wheels for these two drive trains. Does anyone have any they can share? Thanks in advance!

While it's not completely what you are looking for, 5-Star Tuning has a couple of dyne graphs which show the differences in what they have been able to pull out of the 2017's versus earlier 6.2's. That might give you a good idea of what the difference at the wheel is between the two generations.

The attached thread is really a comparison between the 6.2 and 6.8 but you get the idea. The trans is doing something here to get more power to the ground.

Thanks - I saw those charts on their website. Which line on the 2017 chart should be compared to the green line on the 2011 chart? Their charts are kind of a mess...the torque and hp indicators are swapped from one chart to the next and the labeling on the 2017 chart isn’t as clear as the labeling on the 2011 chart. Green should be compared to green I guess as long as you compare the correct scale for hp/torque on the respective charts.
If I’m reading this right, the 2011 has a peak torque of 268 ft-lbs at 4700 rpm and the 2017 has peak torque of 335 ft-lbs at 4000 rpm. And the 2011 has peak hp of 255 at 5500 rpm, with the 2017 having peak hp of 300 at 4900 rpm. If accurate, that’s quite a change.

That's how you would read the charts, but I would take dyno's with a huge grain of salt. They are probably numbers from completely different dyno's and completely different ambient conditions. You could two of the exact same vehicle dyno'd on the same day on the same dyno and the numbers would be completely different.

Agreed. Best to have both done on the same dyno at the same time to eliminate protocol differences but this is all I’ve seen. Honestly I’m surprised no one has tested them back-to-back to validate Ford’s torque claims. On the other side of the equation I’ve seen claims (with specific numbers) that Ford has lowballed the performance on the 5.0 and I believe the ecoboost in the Mustang, so who knows.....

Something to keep in mind as well...the "new" transmission is only used in the gas 250's, not the 350's. The current transmission in the 350's is the same as what used to be in the 250 during the 2011-16 models. So any of the theories that the increased numbers are due to the transmission go out the window if someone is referencing an F-350.

The only data I have to back this up isn't much- it's the fact that you can't get the "new" transmission in a diesel, or an F-350. That right there tells me the transmission isn't up to the task of the same payload and towing requirements as the old transmission.
I have had a 2011 F-250 6.2 for over 7 years now, and I can say with confidence, I certainly wouldn't want any "less" of a transmission in it. In fact, I ordered my new 2018 F-350 with 4.30 gears, specifically to ease the stress on the drive-train, and increase the safe towing capacity of the truck.
Don't get me wrong, I drive my truck 90-100 miles a day, and a lot of that is unloaded. A hot-rod F250 would hold up to 95% of my tasks and save gas doing it, but when I'm towing 15k+ lbs of logs 50 miles through a bunch of steep hills, I'll be happy I have a stronger transmission with better heat capacity.

I haven’t seen a rash of complaints about the new transmission but you’re right in saying it is built as a lighter duty transmission. Ford integrates the maximum torque capability into the transmission nomenclature. The F250 gas truck has a 6R100 transmission while the F250 diesel and all F350 trucks get a 6R140 transmission. The two transmissions are rated for 1,000 and 1,400 ft-lbs respectively. Since the gas engine doesn’t generate anything close to 1,000 ft-lbs I don’t see it as a concern.
