First 2024 Duramax on the Dyno!

We’ve got one of the first 2024 GMC Sierra Denali 3500 HD Ultimates in the shop! In Gale's latest video, he runs it on our chassis dyno to see how much of GM’s claimed 25 horsepower increase actually makes it to the wheels. Gale walks through the new truck's beautiful interior and exterior before strapping it onto the dyno. If you’re familiar with powerful diesel trucks you know that peak horsepower isn’t the most important number. Gale explains torque rise using a dyno sheet. This is the vehicle’s lugging ability. Finally, he explains why modern diesel trucks will actually never reach their peak torque thanks to the transmission back-shifting (down-shifting). Performance parts for the 2024 Duramax L5P are now available at bankspower.com with more being released soon.

[@user-qh8nw7rf2f]

Great information! Now, please install a Banks CAI, iDash and Derringer on that puppy and run that test again multiple times to show us how the Banks power adders affect the HP and torque levels and that torque rise percentage at different power level settings! I’ve installed those items and a pedal monster on my 2020 L5P but I don’t have a chassis dyno to determine how the combination affects those power levels. It would be really interesting if Gale would show and tell us how, why, and how much these mods can improve the power of this already impressive engine.

[@CGT80]

@@nou8257 How much would a truck like yours sell for right now and how much would it cost to bulletproof the engine and trans? I have been there. My parents bought a 2005 f350 6.0 with a partial bulletproof job on the engine, multiple tunes, intake, large free flowing exhaust, etc. and only 75000 miles. It pulled like a beast and I considered buying and building one like it. Instead, I ended up with some good paying work and bought a 2020 Chevy z71 LTZ CCLB with all the extras (same as the high country trucks and same price at $74k sticker and $68k after rebates and a deal from a neighbor in June of 2020). The L5p with the derringer and throttle monster spanks the dually f350 with a hot tune when empty and the L5P tows far nicer. It is never in the wrong gear our out of gears and never runs out of power, towing the same toyhauler and dump trailer with equipment in it. The 6.0 sounds amazing when you get on it but the lack of exhaust smell and how quiet the duramax is while towing even a decent load up steep grades is very nice for long drives with middle aged ears that have been beat over the years. The ride and comfort as well as cameras and all the other features is great. My other pickup, was my daily driver, is a 79 Chevy C20 with a well built 406 SBC and gearvendors overdrive. That ford is great, but if you are willing to spend the money (I didn't already have an older diesel and I do a lot of out of town work) the duramax is a beast with luxury.

[@nou8257]

@@CGT80 I was offered 30k for my truck couple years ago and I turned it down. the value of something differs to each person and this truck is what I wanted so when I found it I bought it. And there is no bullet proofing that is a very over used term with 6.0's. my truck is a 6.4 and to bullet proof it as you said well its kinda already been done as the emissions system is gone it is what killed those trucks regardless of what a large number of people who have never owned one will yell against them. But to toss a number out there if I just went and put 6.7 steel pistons into my 6.4 did some other upgrades to it i'd say I could do that in the 10-15k range with me doing the majority of the work since I have plenty of tools to take the engine out and disassemble it for the machine shop. I can also go the cheaper route too buy the adapter kit and put a 12v cummins in it for around 10k or less and then it would have one of the best engines ever produced. I tow with my 02 f350 7.3 with a zf6 speed manual trans have easily pulled around 20k with it no real problem just about never have had to leave 6th gear pulling a hill with it vs automatic transmissions which usually die when used for towing and don't know when to shift correctly to use the engines torque. The exhaust smell of a diesel never bothered me. I grew up around diesels and all kinds of cars I prefer the old diesels to the new ones that burn my nose and eyes with their dpf junk espically in regen. But hey the duramax works for you that's great. My old trucks work for my applications pulling my trailers.

I wonder if the fans could be timed with the dyno so as to provide the same wind speed as what is on the gauge cluster, that would be cool.

[@Bootchair]

technically could be possible. would require a redesign of both dyno and fan to, probably cost so much to do and probably wont make much difference.

[@adammorrison3343]

Considering the truck maxes out at 96 or whatever it is, the 60 mph fan is good enough.

[@steveatx8295]

Great work! Hearing protection for the boss would be a good idea. ❤😊

[@bakfixx]

Very informative. If a manual transmission option was available, wouldn't the peak torque number be more relevant (usable)? And if so wouldn't this be a nice message to send to the GM Factory regarding a manual option for some configurations?

[@thegreenerthemeaner]

Emmissions plain and simple. The 10 speed transmission is so the engine can be kept in optimal RPM for Emmission control. The manual transmission version in 2008 for instance was still at LB7 power levels. Auto equipped (LMM) was much higher. Not everyone can drive a manual successfully with todays power pulling 30k and not kill the clutch. Automatics always pull more consistently.

[@Chris-cg8bf]

One smart guy right there. More real world testing than others do or have.

[@roberttanner4225]

I have 3 more years with my 2021Chevy 3500 Duramax. I can't wait to se what they have by then!

[@75zl1]

Any info on the derringer for the 3.0? I would love one of your set ups for it!

[@bn4172]

It is perfectly reasonable that the transmission control does not allow the engine to lug down to peak torque because an engine's peak torque rating is essentially meaningless. It's torque at the wheels that is important and at any given vehicle speed the maximum wheel torque is achieved when the gearing allows the engine to run at its power peak, not the torque peak. The designers of the transmission control know this so they program it to provide the best real-world performance. As Gale correctly said the only time that peak engine torque comes into play is in first gear but that is theoretical in the real world since you'll run out of traction before you run out of engine torque.

[@blank0fff]

Excellent information! That said, I’d like to see a side by side comparison between this configuration and a lwb dually to show if there is a significant reduction in hp/tq at the wheels because of the longer drivetrain and the additional rotating mass of the dual wheels/tires.

[@crezychameau]

6:22 I can attest to that, I recently pulled 20k up a 10 degree incline at a landfill in Texas while in 4 wheel drive low and it can stay at 1600 in 1st or 2nd gear if you throttle it just right but the beautiful thing is, the truck doesn’t need to stay there. I climbed that hill many times and usually with at least 18k behind me and more often then not it would shift up to third during the climb. Strong truck.

Thanks fo the video & test however you and your crew missed a very important aspect to cooling - your big fan works for the radiator and inter-cooler, but its sits too low to be beneficial for the air intake on the hood. My recommendation is if your looking for valid dyno test results, you'll need to jack up the fan unit to include the hoods air intake since this is vitally important when your looking for accurate results.
