I was honestly very impressed with this new updated 2024 L5P duramax diesel engines on my towing loop. the previous L5P duraamx engine was fine but this truck made a big difference.
first up was our off the line acceleration test and well this Duramax comes with the 10 speed Allison transmission and it has the ability to fully Lock up the torque converter in first gear so this should give this Duramax diesel a very nice advantage over the competition.
Next up was the highway acceleration and this new Duramax Diesel was pretty quick beating the 6.7L cummins up to speed. the Powerstroke however was quicker and well that ford powerstroke is a very fast truck.
when it comes to the exhaust braking the previous L5P duramax engine was pretty weak in my opinion but this updated exhaust brake seems to be performing very very well. I was happily surprised with how well it worked. and it was much better then the powerstroke in my opinion.
when it comes to pulling big hill with a loaded trailer this is where the Duramax diesel shined. this engine was probably the best i terms of maintaing speed and pulling loads up the hills on my towing course. I was very very impressed with this Duramax engine.
Let me know what you guys think!

the answer for what to buy is actually simple if you tow something kind of heavy every couple weeks just buy the gas engine if you tow for work or atleast once a weak with a heavy load buy the diesel it just makes the towing so much easier

I am glad you used the cruise control to show what the transmission tuning was capable of. I have a 2023 GMC 3500 and I feel the exhaust brake itself does a very good job, however sometimes the tranny tuning isn't the best and it doesn't seem to be consistant. If I use manual mode the exhaust brake works extremely well. Power wise, I was going to hold out and order a 2024 until I saw the power numbers and the fact that the ecm hasn't been cracked yet, I decided too buy the 23 knowing that I could easily add power. I added a Banks Derringer and Banks cold air intake and I am not disappointed.

I talk about the new electrical systems on the 2024's and how the new ECM's may be challenging to crack - very good point. Also the 2024's seem to be experience alot more software issues then the first gen L5P so it's not all sunshines and rainbows with the new engine.

Banks did a dyno run on one of these engines that tells the story. According to him "peak" numbers are just for bragging rights and are numbers one will never see in the real world. What he said is this engine makes a lot of actual usable torque to the ground. Too bad he does not have similar dyno runs for the RAM or Ford, it would be interesting to see where they stack up beyond just peak numbers. I personally own a 24 3500 DRW w a Duramax and it tows my 5th wheel which scales as 24k lbs. It tows this load very well. I have has no issues towing in places like the Smokey Mountians which has some pretty long steep grades. Engine and Transmission both seem to have very good thermal control and neither gets much hotter than they would just driving around town unloaded. As mentioned in the video i think fuel economy is this engines downside. It seems GM was very aggressive with the regen programing on the 24. according to my Idash mine will regen every 200 miles or so unloaded and about every 450-500 when towing. I think that is what is causing the poor economy overall but if it keeps the DPF from clogging its ok by me.....

For towing up grades like that, is it a potential downside that it does not downshift? I get it’s a good indicator of the engines potency, but wonder if downshifting would yield better fuel economy and lower egts to boot.

@TheGettyAdventures 3 ай бұрын

Could be, but with a turbo charged engine it will just feed more boost into the engine. For fuel economy it may be better to just downshift, I generally would trust the truck in tow haul mode to put the engine in the optimal situation

I'd like to see the cummins do this test with a 10 speed. Given it's very low redline vs the v8 diesels it of all these 3 engines needs more gears the most.

@slidewide1999 3 ай бұрын

And with cruise control that isn’t so lazy. In my Cummins powered truck, there’s a hill near where I live that if I set the cruise at 55mph, it’ll lug up at 53 and roughly 1100rpm, but if I bump up the cruise midgrade to 57 it will immediately pull to and hold 55 without downshifting. It’s not necessarily a power issue, it’s the lazy programming of the cruise algorithm. But yes, a 10 (or the hopefully pending 8 speed) will finally put the Cummins on level ground with the competition.

@diverjp771 3 ай бұрын

Cummins would be fine with maybe an 8 spd probably but the 6 just isn’t built to handle a 10 spd. That many gears would actually make things worse.

@JohnSmith-ev1sm 3 ай бұрын

@@diverjp771 No, it needs more gears because it has such a limited range where it makes power. Right now it is using RPMs that are less than ideal because it has no choice: when it upshifts the next gear is lugging because its too low because the ratios are spread far apart. If you have a 10 speed then the gear ratios are closer, the shifts keep it within a few hundred rpms. Same reason why semi trucks have so many gears, they only have a few hundred rpms to play with so they need those very close ratios.

@slidewide1999 3 ай бұрын

@@slidewide1999 You absolutely can lug a cummins at low rpms. Been there done that. Ram knows this as well which is why the next update its getting the 8 speed across the board.
