2024 Duramax L5P Engine First Look And Comparison | Banks Exclusive
Вставка
- Опубліковано 30 тра 2024
- Gale Banks inspects a new 2024 Duramax 6.6L turbo diesel engine and compares the parts side-by-side with a 2023 model; data you won't find on a spec sheet. Available in the '24 Chevy Silverado and GMC Sierra, the engine boasts 470hp / 975lb-ft, up from the previous generation's 445/910. Improvements to the engine include a new turbo, pistons with tapered bowl, cylinder heads with improved cooling jackets, higher-flow injectors for greater fuel injection pressure, fuel rails to handle the increased pressure, improvements to the glow plugs, improved engine braking thanks to a more powerful turbo vane actuator and upgraded valve springs, along with the latest generation Engine Control Module with new Global B architecture.
All of these new parts look seriously durable, but will they translate to more power? We already have a truck on the dyno. Stay tuned!
Banks prefers AMSOIL, the leader in synthetics.

Gale is a damn national treasure in the diesel industry and packed full of knowledge. Always enjoy his engineering breakdowns.
Its rare to have anyone be so masterful in their field, rarer still to have them share it.
Word! This guy should get a statue raised after him!
Gale Banks is full of knowledge and watching these videos is always a highlight.
Painful to watch, like he knows this stuff like the back of his hand likely already knows everything that’s required though takes us along for this ride forcing us to watch the evolution in a manner to educate future engineers on how to build an engine.
JHB He is a vary smart man when it comes to Turbos, He started it all many years ago.
5 minutes in and it’s better than the actual GM training materials. Nice!
Not only does he explain everything, but I absolutely love the CAD images he uses, and diagram animations that are edited into the video to further explain everything. For someone like me, who doesn't have much automotive experience, those images and animations puts it into laymen's terms and just makes this such a pleasurable learning experience.
Gale's videos aren't just "here's X information, you can do Y things with this information", his videos show the type of teacher who could talk for hours and hours and still make every bit of it interesting.
Now I understand why Banks, the company is what it is. This guy is a legend!
I could listen to this man talk about engines all day long. His explanation of how things work is second to none!!
Gale is getting up in age but his mind is sharp as a tack. You can tell he is passionate about diesel engines and what makes them tick. Great job!
I have a Duramax and took to the Banks shop. Boy, what a difference for power and engine performance. He has some positive answers for the Duramax.
On the fuel rail pressures, all of the comparisons are at peak. I'd be interested in if the pressures were raised over the whole throttle map, if peak is reached sooner, etc...oh crud, I'm a nerd.
I love these kinds of break downs, keep them up Gale!
Excellent episode! As far as sound levels go, only the introductory music stings were mixed too high. It is great to have large-print written out title cards for each part of the engine that Gale is describing. I love the detail you all get into. Please, keep it up. Love it.
Yep, equalisation.
Sounds pretty good, good compression!
I've never ever watched a video on this channel and not left with new knowledge to contemplate. Thanks for everything you do for us Gale. You're an absolutely gifted teacher
Sounds like the engineers at GM/Duramax have been paying attention to the master of performance, power, torque, and reliability.
😏
Gale I truly wish I had tried harder to get a job out with you all when I got out of school. 15 years working at Cummins R-D but I still enjoy your technical videos.
Holy Smokes !!!!!!!!!!!!!!!
Gale Banks is 81 years old and SHARP as a razor! Bro, keep up the great work!!!!!!!!!!!!!!!
I could listen to Gale talk all day long truly a master at his craft.
Love these episodes and breakdowns. Plus going into why the manufacturers do what they do.
This man is the Bob Ross of the diesel world, I can listen to him talk all day long and actually understand what he is saying which is insane for a person like me lol
Ridiculous how much i love listening to this man talk about engines. Although now i feel like my 2018 l5p isnt capable of pulling my 10K camper 3 times a year!..JK, this truck is so much more than i need and i love it
Always taking us to school.
Thank you Gale. Love learning your stuff.
Keep it up, great stuff.
Thanks, will do!
@@bankspower increasing the surface area for combustion to occur simply makes too much sense so huge shout out for doing that in the first instance. As far as what the technical term be *"turbidity"* in the #flow_control business is a literal Industry unto itself but absolutely for a pressure based system which diesel is as opposed to petrol/gasoline ignition combustion the cleanest burn possible (no residue) is absolutely 100% spot on correct to say not only most *"efficient"* (fuel needed to generate ouput) but more importantly and why diesels still command premium over petrol/gasoline is because of how robust the basic functioning of the engine system is over the lifetime of use which ideally in the trucking World which I once knew was measured in the *MILLIONS* of miles.
*"heat"* (friction technically) is a problem absolutely and that is a sadly all too easy to explain issue namely "air" as you term it is 70% nitrogen which has been the ruination of every high output motor ever put together in Human existence as unlike oxygen which is the combustion fuel very dense nitrogen is the "heat" that is combusting your diesel fuel to create the power output. All of this "mixture"(soot) is what needs to be expelled and again spot on this is a sign of inefficiencies and power loss being generated in the combustion chamber itself and over time.
The most simple solution is of course just run at lower speeds and rpms/problem solved but these aren't farm Tractors absolutely so one possible solution and again I am in no way an expert but I certainly know a Rocket Scientist or two forced to spool up pumps to deliver fuel *DIRECTLY* into the air itself as power delivery so they are sitting on a bomb/no containment and think about this chemistry problem night and die and this project here being *internal* combustion not lighting the air on fire my first thought is to add *"dimpling"* or *"dimple holes"* like a golf ball to add even more surface area for the fuel air mixture to combust upon instead of simply within. Point being forget the "flow" let's maximize the *MIXING* fuel plus air creating better bonding best possible bonding between fuel and air through some kind of *"effecting droplets"* process.
Probably been tried and deemed a dead end but that would be my two cents for this challenge anyways.
Crawl walk run in anything diesel as anything that works great as a tractor type if then leveled up to the commercial truck Class 8 type ... well, congratulations you just made the best Tractor engine now too!
Can't say enough about the importance of both fuel and air filters in these systems plus fuel cleaning *"detergents"* to free up any buildup carbon which is normative. Ironically enough gasoline makes for a great detergent one of the best so imagine wonder on wondering that one for a minute and drop the urea but at a small gasoline tank and *"cleaning port"* might be another thought as far easier to pour in gasoline than jugs of urea which was one of the reasons I was glad to get out of the trucking business period.
Don't even get me started on methanol tho..
I watched a UA-cam video the other day making me rethink buying a '24 duramax.
This video makes me rethink that video.
Banks makes this new design look fantastic!
The in depth information on the motors, tuners is surreal. Being a relatively new to owning a diesel, i’ve a lot from this man.
Thanks for sharing! The channel is such a wealth of knowledge. Gale is a legend
Check valves in the piston cooling jets are a great innovation.
They've had them on European and Japanese engines for at least 30 years if not longer.
@@mattsmith4053 isn't that fuckin thing Japanese?... ISUZU
@@elroyelblander6277 didn't realise Isuzu were involved with designing them.
. Backwards compatible with 2023 and back engines? Be cool to increase idle oil pressure just with a piston cooler bolt change.
@elroyelblander6277 - Duramax is not a Japanese engine. DMax Ltd. company is 100% owned by General Motors with GM/DMAX owning of the intellectual property on the L5P since 2017. Isuzu is no longer involved with building the Duramax engines. Even better, Duramax engines are built right here at home in Brookville and Moraine, OH.
Gale is the only person i will sit and listen and watch for hours talking about engines and performance.
I have a older Duramax I love it and I love seeing how they keep getting better and better every year
I know. It's refreshing that there isn't some regression of quality.
Awesome video! I know absolutely nothing about diesel engines, but I'm always looking to learn more about everything. This video is very informative. I appreciate you sharing your knowledge, Gale!
Nothing better than listening to someone that's passion is their career or life's work. It's not often you find it but obvious when you do..
As ever great video from Mr Banks! With the 24 turbocharger, are they measuring turbocharger speed? I see the sensor on the side of the compressor housing.
I am a high pressure engineer and adding material to the od of the fuel rail doesn't really make it stronger. Your weak spot is always going to propagate from side ports. Seems they have tried to fix this by adding even more material to just where the ports are. Once again tho not necessarily stronger from this. I would really like to see inside and see the stress propagators
Gale you are a wealth of knowledge i truly enjoy watching you explain the technical things truly educational thanks
Very informative and awesome video as normal. Plenty of upgrades for sure
Spool is in!! Gale Banks may have forgotten more than many will ever know.
GM's turbo technology has surprisingly advanced very well in the last 5 years
Yeah it's funny how World War 3 with Putin Russia suddenly improves everything.
I just saw a video on Adept Ape’s channel about Speed of Air Engineering’s new piston technology and your engineering prowess seems like it would be an ideal match to really gives it a well documented test and give them the feedback needed to really hone the design in for maximum benefit.
Incredible engineering
Gale Banks forgot more than I’ll ever know
Always learn something from this man, I am impressed with GMs updates as well.
Better then the online training I used to do with GM 😅
Gale, you are an absolute legend! Thanks for taking us on this journey with you!
Have a great day! And God Bless! o7
I love this incredible man with so much integrity and he's also just a hoot to watch!
Mr Banks, you my friend are just a straight scientist! Love love love it!! Keep on killing it. Living legend
Have they improved injector connectors or can we expect injector terminal fretting at just over 100K miles?
Gale gets a new motor immediately wants to push it till it breaks then make so that it won’t break. What a legend and a gift to the automotive world
Thanks for more videos
Very interesting. Thank you for the video.
Nobody... NOBODY breaks it down like Gale! 💪
I really admire Mr. Bank’s knowledge and appreciation for engineering and engines.
Modern engines really are works of art. It’s so incredible to see how much engineering goes into each one. It’s almost a miracle that everything works in perfect harmony.
It’s also good to see GM making an engine that gets a nod of approval from Mr. Banks.
mr.banks is the david vizard of the diesel world.tons of respect for both of these gentlemen.
Gale Banks makes the engineer in me proud. LEGEND.
Mr banks you’re the best in the business thank you for all your hard work and dedication to getting this right
The man is a legend, much respect from Australia.
luv te way this bloke explains certain aspects of the workings of these engines that were a mystery until his way of explaining
Mr Banks is the definition of a man. Full of knowledge and knows how to use his hands with his brains!! Impressive.
Amazing wealth of knowledge and info!
I always know I’m watching a professional when he properly refers to an oil “gallery”, rather than “galley”. They’re not called “galleys”, never have been, never will be. There is much more to indicate his knowledge, but that’s one that stands out. This is a pro.
Wouldn't you like to know just half of what he has forgot about diesel engines? the man is a genius. Love every video..
I've heard about the grant gear pin sheering and the cam goes out of time, what is your take on it?
5👍's up Mr POWER thank you for sharing 😮
UUh! Have been waiting for this since the new L5P was announced! Cant wait to see what you guys come up with
I'm curious as to the compressed thickness between the two head gaskets , I wonder if they're the same?? Great Video !!
Excellent. Looking forward to the next episode.
Fascinating! I worked in a coal fired powerplant for 15 years. Lots of similarities between coal combustion and diesel engine combustion.
Hey Gale, is the Duramax block a graphite design or cast iron? What do you think of over square bore and stroke vs the under square like the Ford powerstroke? And aluminum pistons vs steel like the Ford?
Thanks, we all really like the details you provide.
Great video as always.
awesome visuals, Good job media team.
Awesome job crew!
Thank you!
Only a passionate engineer could describe a bolt as sexy 8:32
I could listen to this guy all day long
Very excited for mine to arrive
Amazing , Thank You .
The new modern diesel engines are just plain works of art! I love my 6.7 Cummins for it's simplicity, but the new Powerstroke and Duramax are just amazing engines.
I've never owned a Diesel, I work on Jet and petrol engines but I can't absorb enough of Gale's knowledge. 🙂🇦🇺
Excellent breakdown comparison and explanations from an excellent teacher
You Rock, Mr. Banks! Good details! Maybe I can run a touch more camshaft on the stock '24 valve springs.
Was waiting for this
Thank you for your knowledge, dear master.
Great video!
Thanks!
How does one assemble the check valve in the oil squirter retaining bolt?
That fuel pump is amazing & it reminds me of a rotary motor
I enjoyed the part of the video about the Turbo and the different screw design. It's clear that making this connection point uniform with the same angle improves the tightening, which becomes more uniform, as well as the theoretical capacity that can be absorbed thanks to this small modification. This also means that the possible upgrades to be made on the Turbo will be improved and could even make the design process easier. In short, that's my point of view, haha.
Awesome explanation!
What’s the fix for the newer L5P exhaust manifold leaks? Seems to be common as more and more trucks get higher in mileage. Most noticeable when truck has exhaust brake on and it’s fully engaged, high pitch squeal.
I’m curious if you had an injector the sprayed fuel in a slight rotation what it would do for uniformity if it does anything
Great information.
My family, I'm proud of him, "Gale Banks" is a good person! and smart as hell! :)
do you know if the new 2024 LP5 pistons can be used in earlier gens of Duramax engine builds and if so do you think they would be a good option to use ? thank you
GB is such a smart guy, when I grow up I wanna be just like him.
He's forgot more than I know
I just had the opportunity to drive one of the new ones today.
I'm curious to know what the extra valve spring tension means for the cam?
Always I'm formative, thanks for breaking it down
Any time!
Great job Mr. Banks! Now I’m very glad I waited to buy..
What's your opinion of Speed of Air pistons?
I remember seeing you on trucks or was it extreme 4x4 my dad had a 2003 2500hd duramax diesel ground effect edition when we saw you on the show in 2005 maybe my dad order the banks six gun with the speed controller I think it was 355 add hp brings back memories love this ❤
the freewheel of the old diesels is what made them fun to drive no exhaust braking
Gale Goodness as always🎉
I love it cant wait to it perform on the road it will be crazy
Stepped pistons, were used a long time ago. Mazda used it in their 2018 update of that diesel engines
will this duramax crank break in half at the middle journal counterweight under high loads like other dmaxs?
Mr. Banks can we get a comparison of the LBZ to the L5P? Which one is better at what?
Good Stuff as always.
