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.

    Whoever had the idea to make the graph's text fuzzy until Banks put his glasses on gets credit for making me laugh out loud.
  • He Never fails in fitting some more knowledge between my ears. Even if I'm leaking it faster than it's going in at this point in me life. Thank you, Professor Banks !
  • @codyb.
    The numbers going from blurry to sharp when Gale put on his glasses. Nice editing touch! 😂
  • Bought my first Banks Engineering products 30 years ago for my '93 K3500 Chevy dually. It was an awesome kit. I now have all of the Banks offerings for my 2017 3500HD GMC dually and love them all! Mr. Banks is an icon in engineering, not just automotive, but engineering in general. He doesn't stray from the fundamentals of engineering. He uses engineering to guide the design process. It is painfully clear how superior his products are over the competition. I learn from him on every video. Thank you, Sir.
  • OMG, i grew up reading Gales hot rodding books, back when books were a thing, and hes still going strong. I watched this vid with my grandson and he asked me who the old man was? I told him that's not an old man boy, that's a legend.
  • Legit Gale is a man after my own heart. Data. Testing and thoughtful modifications along with careful implementation is super helpful
  • Loved the simple walk through and explaining the numbers and how and why your system is best. I’ve never considered the dyno numbers with hood open or hood closed, but you make an excellent point.
  • @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.
  • @HOMEWORK4.0
    You are on another level Banks! You and your crew are like the NASA of automotive. Thank you for your desire to test, engineer, explain and repeat!
  • @OK2FLY
    Love the production quality and b-roll. Even on these simpler films👍
  • @troyt5309
    Just grabbed a 2024 Denali 3500 dually, Love the Powerstroke, but as long as Ford keeps using a CP4 fuel pump it’s not an option I’m willing to consider.
  • @Hitman-ds1ei
    Finally someone talking my language of torque rise, as we have done forever in truck and mining, now I feel at home watching this
  • @tg9388
    Love these updated videos please keep them coming
  • @Ttruck4x4
    Really interesting. I really hope that Mr Banks and the after market community are gonna come up with something useful for the 3L duramax.
  • @blk7gxn
    A classy trustworthy and most knowledgeable guy. Always enjoy your videos, thanks very much for sharing your knowledge.
  • @dazzleyd
    This guy is awesome! He has a really good way of explaining everything
  • @fooyung1987
    Thank you SOOOOOO much for the audio balancing! I really enjoyed this video, mad respect!!!
