Apologize if a dupe. All the platforms with the 6.4 are getting power/torque upgrades. If the 2022 2500 does not partake, I may have to gravitate away from RAM. The 5th true gen is also taking forever.
 
I am sure RAM will get their best designers right on it as they don't want you to gravitate away as that might sink the company....
my joking has to do with fca has stuffed a 470hp 6.4 into a jeep challenger, charger amongst various models but they cannot do that with the ram?

The ram 6.4 is much more desirable than the charger/challenger variant. Heads are stronger/made of better material to withstand the heat of towing, and the block is cast to be stiffer (similar to hellcat block).

Soooooooooooooo....

hear yaaaaaaaaaaaa. want more oomph other than slamming a blower on it, my point. Think the factory can add more hp/tq without compromising the stronger engine components or durability
 
I get it and agree... Always looking for more powa! Im the same way.
 
been saying this for years, the Power Wagon should have the SRT motor due to not towing as much anyways and the name Power Wagon is a perfect play on words!
 
I tow all the time, and so far, I’m not disappointed at all. It’s a work truck, not a hot rod. However, an SRT 392 in a 1500, that would get me stoked!
 
Please expand on your first sentence. I understand AUC and torque, that's it!
 
In short, work engines generally have a flatter and broader curve (negative Kurtosis) with peak power arriving at lower RPM (positive skew). Race engines are normally the opposite with a very tall and narrow power band (positive Kurtosis) very high into the RPM range (negative skew). The GSXR-750 that I raced in the WERA National Challenge Series was flat and largely anemic below 9k RPM but between 10-13k she was happy and overflowing with power - that's where the engine was designed to run.

Excellent explanation, got it! Now... who the hell is Kurt?
 
The reduced or limited power in the HD applications also is done for reliability at or near maximum outputs. They know that if you put a SRT Hellcat engine in a HD truck and attach 15K lbs behind it and the engine is worked towards it's limit for a larger percentage of its service life, that service life will be compromised and be much shorter than the consumer will tolerate. By downgrading the output while still broadening the TQ curve, you get a harder working engine with satisfactory service life and acceptable performance. You can look at Industrial Injections 3K HP race diesel engines and ask why we do not get similar from the factory in our retail purchased trucks. Because Industrial does not care if they replace that engine or rebuild it every couple races/sled pulls. All they care that it wins and you see it on the podium spot, remember their name, and call them for your upgrade parts. They know that a HellCat is not driving around putting down 700HP for any appreciable amount of time, in the big picture that engine spends most of its life cruising around using a fraction of it's ability with blips into the full load now and again. Our trucks spend a comparably significant amount of time deeper into the performance capability than your sport coupe.
 
I don't disagree with the very excellent explanations given here! But, I would just point out that GM has a 6.6 and Ford has a 7.3 and they are built the same way (for the same conditions and use case) as the Ram 6.4 yet they produce more power everywhere. I do think its time for Ram to upgrade the 6.4.

A friend of mine drove the new Ford 7.3, and he said he would not pick it over the 6.4, and he is a Ford man.
 
It's good to see you guys saying what I've been asking for months which is, when will Ram leave that party and come to the new one?

Ford's 7.3L makes more torque below 2,000 RPM than Ram's 6.4L does at peak. AND gets 1.5 better MPG to boot.

GM even has an all new big displacement V8, after using the same one since Bill Clinton was in office.

Ram needs to RSVP very soon or they're going to get left out of this party. I don't care if there are guys that say the 6.4L is adequate for towing. 429 lb/ft was so 2012. A decade has passed. It's time to ramp it up. Hell, the 1/2 ton trucks from Ford and Ram both have engine options that absolutely trounce the Ram 6.4L.

They need to get off their asses and bring the 5th Gen truck to the HD lineup NOW, and they need 50 more lb/ft of torque and better efficiency while they're at it.

And don't even get me started on the Power Wagon vs. Tremor issue. I don't give a rip that the Tremor "only" has front LSD and the PW has a locker. 98% of owners never touch the front locker button the entire time they own the truck. There is ZERO excuse for bringing a 3/4 ton truck to market that has 1) no diesel option and 2) less payload and towing than the 1/2 tons. That's a disgrace to the Power Wagon heritage. You can get a Ford Super Duty Tremor with your choice of engines, your choice of axle ratios, factory 35s, a winch, a lift, and all of the payload and towing that you'd expect from a 3/4 ton truck.

I'm a Ram/Jeep guy and it's the only thing I buy, but geez....they need to get their head out of the sand. And consumers need to stop defending them. Pressure them to keep their trucks fresh.

I think you need to test them for yourself. If he drove them back to back he would think differently. the 7.3 10speed is much nicer.
 
Each of the Big 3 has their own specific "highs" or "bests" in the segment.

My worthless opinions:

--Ford--Engines with the most horsepower. The 6.7 PS is a BEAST and runs as hard in stock form as a tuned HO Cummins. Their new 7.3 gasser is also a monster and is getting rave reviews on the Ford forums--cam in block design (Think LS-like) is a basic, proven platform.
--Ram--Interior man!!! By far the best interior (where your spend most of your time!)---No one else is even close. Ford is terrible, hard plastic, GM looks like a childs playground inside with a small screen. Also the Cummins is back with the cp3 for 2021 so this is a tough to beat engine.
--GM--Purely subjective but i like how the new trucks look. Its a polarizing design and not everyone likes it but I sure do. Also it can be argued that the IFS offers a softer, more comfortable ride than Ford or Ram.
