Thoroughly enjoying my 2020 RAM 3500 dually chassis cab- 6.7 Max tow! Engine A is badass! No need for HO here, it's a work truck! Today getting 18-23 mpg w/no trailer.💪🏼🇺🇸💪🏼
I have driven both back to back with same cab configuration and I couldnt tell much difference. Plus I dont like the idea of the low compression engine on the HO...I will pass and go SO.
Barr Thom Actually the 16.2:1 compression ratio is much more common than 19.0:1 which is the highest ever compression ratio in a pickup and is much more likely to blow head gasket. Duramax runs 16.0:1 and 6.7 Power Stroke 16.2:1. And HO Cummins 16.2:1 now too
Hey Paul Great videos..my 2014 type A Engine that makes as per RAM 325/850 ..and I tow my family around on LONG distance trips gets 22mpg...ill keep my type A with the 68RFE..GOD BLESS you and your Family
You got any numbers on the MPG difference between the Cummins HO and normal? Is the 2021 HO still lower compression? Also, any numbers on 3.73 v 4.10 final gear ratio? I'm wanting to optimize MPG for towing big-ass RVs trailers, so up to 20K max weight toy-haulers. Was looking at a 2021 RAM 3500 SRW 4x4, but I want "just enough" that gives best MPG and what would the MPG be? You think 3.73 on normal Cummins is enough to tow 20K and I'm also curious about what the mileage is towing as well on HO versus non-HO Cummins.
No need for 1000t unless you tow over 25k I tow 14k with a 97 12 valve with a different fuel plate and a star wheel adjustment for a little better pep , as long as the converter stays locked up it doesn't slow down
gt40x4 good question but I think displacement numbers have to do with bore size and cylinder length which I don’t think changes.... can’t say I’m sure on that. Another thing they done sometimes to change compression is drill little notches in the head beside the valves but I don’t know what they did for sure 🤔
heads, pistons, stroke...all could impact the compression...my guess is same block, pistons, stroke...probably different head or head gaskets to reduce compression on the HO engine.
@@crazyhass84 A lot of good things is not always on forms or online, you have to figure it out for yourself or is known only by a couple people information is not always online
@@BarSpringOutdoors no fucking shit. However, 4mpg is HUGE! U would know that if u knew anything. Which would be in every review and all over the forums !
I spoke to a Cummins engineer about this. It's all about the market and end users as it pertains to duty cycles. The 5500's are tuned and equipped for longevity and completely different duty cycle like long hauling etc vs the SO 2500 as a Swiss army knife of commuting, toy hauling and camping etc. They used a fancy term which was basically a balance of three things. I just can't remember them this second. hehe
Now i really wonder the differences. Haven't spent much time on the 19's to know the difference between the two engines. I thought it would only be tuning differences like the 4th gen.
Low compression was done to reduce for NOx...the HO will get less fuel mileage then a SO engine. The lower compression has nothing to do with more power...its only less for less NOx....emissions related.
no. If that were true why not make the ho 19 cr also?! Lower cr does drop combustion temps. Which will drop nox but thats not why they have 2 cr. The ats is there for a reason. Its the same size on a so and ho truck. Cummins is not going to have 2 cr that doubles the amount of testing and parts just to lower nox. The lower cr drops the peak cylinder pressures and bmep. BMEP kills an engine from the mechanical stresses. Bmep is worst at low rpm. This is the mechanical limit preventing higher torque. They wanted to hit 1k + lb ft. Hence lower cr
Can someone please paraphrase this video and just list the differences between the two? I couldn’t watch more than 3 minutes 30 seconds of this because he was all over the place talking about everything but the differences.
Neo Craft LoL 😂 only main difference is 16.2:1 compression ratio and 400 hp and 1000 lb ft torque with the Aisin transmission on HO and 19.0:1 compression ratio and 370 hp and 850 lb ft torque and the cheapo 68rfe transmission on LO 😄That’s the only known difference n essence of the video 🤪
K C Ya the 68RFE is definitely known for its issues and was way under built. The Aisin is a good Transmission stock and not near the issues as the 68RFE...
The block is different it is made of compressed iron graphite and weighs 60 lbs. less. Before you get bothered about that Navistar did this in the 90’s and the new block did not suffer any ill effects.
I’ve wondered already if the main reason that only Ram has a low output is Transmission demand on the Aisin because the 68rfe clearly can’t handle the HO engine. Which is why all 2500s (unless special ordered) and a lot of 3500s have the low numbers and crappy transmission 😉🤪
Anthony Baker Congrats that’s very rare without being beafed up!! Must be you are a very easy driver and tow very little if the transmission is stock!🤗
I dunno, I deleted and tuned my2017 with the 68rfe under 10k miles. I have 40k now and no problems. I have 8.5k miles hooked up to my 10k trailer. I know that’s no miles or big weight but it hasn’t fallen apart like the UA-cam commenters said it would. My 35 inch tires do make me nervous about the trans but damn it looks good. I drive it respectfully, mostly. 🤞
FCA has said they have done work on the 19 68RFE’s. Gunna hold out a bit and see where they land on reliability, I’m sure it will be fine for normal usage.
I just switched from a Duramax to an 18 Cummins. Sooo glad I did
😂😂😂😂 Sry man you getting frustrated was making me laugh!
Thanks for the info.
God damn, keep a train of thought. That is some world class bullshit. Unbelievable, I feel like I lost knowledge with this.
You’re all over the place buddy, might need to think that next video through before you record LOL

I'd love to see a head to head with the standard output vs HO. But no ones seems to have that info.

This painful.. this guy needs to take a course on public speaking
Its 850 ft lbs isn’t it?
Yep
And. 370 hp....

How can you distinguish a low out put vs a high output motor 19-20 ram
Trans
Open the hood. The engine cover will say HO or not.
A lot of people say that Chevys are meant to tow boats.
I am dumber after watching this video!
talk about the trans 68 vs aisin
I was really looking forward to the video but lost interest pretty quick.
Compression ratio has to do with the stroke, no? So would one have a different stroke than the other? And thus a different bore?
Unless the block is different
Most likely same cylinder longer rod or deeper piston on the higher compression and shorter rod or piston on lower compression...
L W would that not change the displacement?
gt40x4 good question but I think displacement numbers have to do with bore size and cylinder length which I don’t think changes.... can’t say I’m sure on that.

Just follow along!
Great video Paul, how many miles to the gallon difference do you think engine B would be compared to engine A? Like 3 or 4 miles to the gallon?
If it was that high the forums woupd be going crazy. I haven't seen it...

My 2018 manual G56 will pull anything
What I don’t get is why the 5500 has less torque than the 3500!?
Coach Alex because they are designed to make power all day long like a farm tractor. 3500 are for Cowboys and 100k miles.

I expected a graphical demonstration rather than a fkn opinion. Nice clickbait thumbnail.
Now i really wonder the differences. Haven't spent much time on the 19's to know the difference between the two engines. I thought it would only be tuning differences like the 4th gen.
Not when they made a complete new block, pistons, rods, crank, turbo. Why the fuck would it just be a tuning change?!
I was told the only difference between the 870 and the 1000 lbs of torque was the turbo.
Should be noted that you're the truck is programmed to give you that 1000 ft lbs only in 1st gear under certain conditions
If you want to haul bug you got to be a truck driver

They wanted to hit 1k + lb ft. Hence lower cr
It has lower compression to allow higher boost levels.

Neo Craft LoL 😂 only main difference is 16.2:1 compression ratio and 400 hp and 1000 lb ft torque with the Aisin transmission on HO and 19.0:1 compression ratio and 370 hp and 850 lb ft torque and the cheapo 68rfe transmission on LO 😄That’s the only known difference n essence of the video 🤪
L W Thank you kindly! I couldn’t bear another minute!! Lol
Neo Craft Lol 👍right 😁
L W I was looking at both trucks and hear bad things about 68rfe trans.. are they really that bad or is Aisin trans the way to go.. cheers
K C Ya the 68RFE is definitely known for its issues and was way under built. The Aisin is a good Transmission stock and not near the issues as the 68RFE...
The other difference is one will last and one will not...
My ‘13 got about the same mileage as my new ‘19
All the diesel engines have a ton of torque. Ford with 1,050.
Can probably find parts catalog schematics with part numbers thatll tell ya what's different
Get to the point and edit everything else out
I have the 68RFE in my 2019 and it's trash. Underpowered for sure
Has it given you any problems yet?
Div Dev no
Tow Piglet I thought the 3500’s ONLY come with Aisin??
Probably why it ended up in a fleet rental program. No Aisin, nobody wanted it.
@@natehawkins2910 no still option
The block is different it is made of compressed iron graphite and weighs 60 lbs. less. Before you get bothered about that Navistar did this in the 90’s and the new block did not suffer any ill effects.
Its cgi. Compacted graghite iron. Dam dude u cant even copy from google.

The 68rfe can handle 1000tq fine, my stock trans 2013 is tuned to 1200 and hasn't had a hiccup for 100,000 miles.

supperterofsanity ya normally fine if driven carefully but iffy with a lot of heavy towing or testing especially with a tuner
