My answer: Because the I6 design isn't as good at spinning fast (which makes HP) as a V8 design.

How high an engine can rev has more to do with it's bore/stroke ratio than cylinder configuration. The Cummins has a much longer stroke than the other two. Great for producing non boost assisted low end torque, but not so much for achieving high revving horsepower numbers There are short or square stroke I6 engines that can rev pretty high. The BMW 3.0L is a good example.

^ This - I too was going to say the same thing about the S54 M engine specifically, which redlines at 8000+

Yeah, no need to wait. I recently put down 587rwhp and 1210rwtq with just a tune and an intake on my 2015 F450....all emissions still intact and functioning.

I would love to see the dyno chart on that and the tuner. Even my deleted 6.7L Powerstroke friends would have a hard time getting that much out of the 2015-2016 engines.

Tell your friends to talk to Absolute Performance in Kenewick WA. That's all I'll say in an open forum.

You have a dyno chart? I would love to see it.

Hmmm, they are adding power the very same way tuners add power through boost and fuel manipulation. According to some people here, that would decrease reliability or is it okay if the manufacturer does it, but not an aftermarket tuner? As Ryan Miliken always says "Tuning does not create horsepower, hard parts create horsepower, tuning simply unleashes it."


Cummins is still playing it very conservatively though. There is still plenty of power to be had with the current HE351VE turbo while still keeping safe EGT's when towing and emissions down.

But they didn't add HP... Why not?

Now, in my mind, the increase in tq will result in a corresponding increase in hp somewhere in the RPM band (area under the curve so to speak), it just may not be a higher "peak" hp.

Guess i'd better look into trading in my '16 Ram CTD. 30 ft/lb more torque is gonna be so much more awesome. (Not).

I was embarrassed to be seen driving mine being 65#' under the new ones. :o

Just drove past our local dodge dealer and the lot is loaded with trucks. Might be good deals on the 2016's that would be a great truck for their needs. All the power only works for the need of the owner. Probably the same for the other brands having their lot full.

Ram has increased the towing capability of its 3500 Heavy Duty pickup for the 2018 model year by offering a fifth-wheel option that would boost the maximum trailer weight rating to 30,000 pounds, Fiat Chrysler has announced.

With the updated capability, the 2018 Ram 3500 would rival towing capabilities offered by Class 4 and 5 medium-duty trucks.

The increase has been enabled by a more powerful 6.7-liter Cummins turbo-diesel and a reconfigured design of the truck. Ram will offer the fifth-wheel as an upgrade through its Mopar Parts division (Part#: 82215769) or an upfit package. The part will retail for $1,395.

The boost adds more than 600 pounds of additional towing capability to a truck that offered 23,770 pounds of maximum trailer weight in 2017 with a traditional towing setup. The 2018 truck can tow 20,000 pounds with a traditional setup.

For 2018, Ram upgraded the truck's inline-six cylinder Cummins engine by increasing torque by 30 lb.-ft. to 930 lb.-ft. The higher torque was achieved through a variable geometry turbo and flow rate increases through the fuel delivery system, according to Ram.

"We understand the attributes most important to our customers within the heavy-duty segment; they demand hard-working, long-lasting capability," said Mike Manley, head of Jeep and Ram Brand.

The 2018 Ram 3500 will arrive at dealer lots this month.
