BANKS is amazing how top notch their engineering is. GM consults them, The military contracts them, they work directly with Whipple, Comp, they are number one

Funny how the guy that helped develop the egr and "clean diesel" technology even rips off emissions then admits you can tune them to the point of not needing the equipment.

I just love listening to Gale explain his thought processes behind everything that goes into engine development. No matter how small a part may play in the role of its use the odds are great that Gale has already either considered it, tested it, and perhaps found a better way of doing it. If the latter hasn't already happened it's probably because that part would just be a waste of time and money (as in the head bolts for example) and that's not what he's about. IMO, Gale's series on differential covers is a perfect example of this. In the vein of a Smokey Yunick (look him up if you don't know) he's a legend in my book!

Mr banks you nailed it on factory head bolts compared to studs.

Gale is a genius. Loved the discussion about the headbolts.

This why Mr Banks you are a God among mortals when it comes to diesel, my grandpa bill bought a 2001 Chevy Duramax dually and build it to the utmost Max using all banks parts and I never seen that truck give a half a smoke. Even after he melted it down Paul and his truck overloaded with the fifth wheel on on propane It still didn't even puff a little bit of smoke when we pulled it into the shop to yank the engine. I greatly app😢reciate the times engineering the dedication and your promise, I just can't get over your dedication to pollution controls and well you have integrity that nobody else in the diesel aftermarket has. Just I haven't seen anybody else's diesel compare, Grandma had to get rid of the pickup not too long ago after grandpa passed. It still runs, has more than a quarter million on it, and I expected to run for probably another quarter million at the minimum.

I could listen to Gale all day! Great stuff!

Yay more to come for the Duramax series , best words I have heard in a bit.

I never wanted anybody to live forever until I met Gale Banks. Such a wealth of no bullshit knowledge.

When Mr. Banks says "that's just my experience" ya better listen. Great explanation. Thanks

Just give GM that clean tune and minimal emissions and get the party started with that freed up power..

Thank you banks for all the L5p content!

I can't imagine how much of an honor it must be to work side by side with Gale banks. I can't get enough of this. Wish this video was twice as long!! Great work boys!

The passion that pours out of this man is palpable through video. I think it is at the core of why BANKS is so successful- He f**king loves what he does and it makes it all the way to the customer.

I hope GM listens to Gale and works with him 100% for these new assembly line L5Ps

Mad respect Gale. I appreciate that fact that you took the time to explain in detail why you prefer to stick with head bolts rather than studs. That makes absolute sense & not something I would have ever thought about. …Making me 2nd guess the bolts we swapped for studs in my buddy’s LB7 several years ago. I dunno whatever happened with that truck.

I don’t understand most of what Gale says but yet I listen and enjoy everything that Gale says and enjoy the discussions. Who knows I might actually be learning something. Love the videos keep up the great work you guys do

The foreplay leading up to the Diesel gasm. Got to love these shows. Banks performance there is no substitute.

Hate to say it but I’m glad you guys are in a time crunch cuz now we get tons of uploads😂

Another great video guys

Keep it coming! I’ve put to work so much from the duramax series into my own fiat. Hopefully fluidampr can find the time to develop a damper, because I need to rev to the moon for autocross.

If It's Smokin', It's Broken! That's so cool how you're setting this engine up. I want one! Haha!

I am sure you guys looked at ARP bolts with the pro's and con's of that product before re-using factory bolts and the reason behind that decision. And yes from the cost of factory production stand point that figures into that as well. You have squeezed a lot out of the factory engine in a short amount of time which is truly amazing in itself. Gale Banks for president I dare say.

The Duramax Future looks good with Mr Banks involved👍

Gale YOU'RE THE MAN

I have a paccar mx13 straight out from the turbo and it doesnt smoke, even under full load. As Gale likes to say if its smoking youre wasting fuel!

79 years old and sharp a razor, bringing us better than TV content for free. God bless you Mr Banks, I wish only the very best for you!

Its gonna be awesome!

Glad to know I own an indestructible Duramax L5P. Can't wait to delete after the warranty and take all that ** off. I get 19mpg but probably will get even more. You guys are awesome at Banks. 😎😎

I am just DYING to see this motor up and running in the truck!

Brilliant Man. I wish we all could Sample just a Blink of His Information in Gales Brain.

What hurts the aftermarket diesel industry in the eyes of the public is the whole "rolling coal" ordeal. I love making power & doing it without emissions equipment when possible (usually older vehicles) BUT I still believe we need to be responsible enough to tune it to be as clean as absolutely possible.

Gale,you amaze me with what you are doing!!!!!!

I finally met the sad giraffe today. Doing a turbo on a 2021 L5D, and was pleased to refer to the plenum as the sad giraffe. Other guys in the shop thought it was funny, and so did the parts guy at the dealership. Hopefully it catches on! That is if it hasn't already.

Oh man so cool can’t wait.

great video

Yea, I recognized those material containers in the last video. Seen a lot like them.

Awesome 🔥🔥🔥🔥

To simplify things, all a bolt is, when it comes down to it, is a very strong spring pulling down on the head. I thas to be strong enough to hold against the cylindr pressures, but also have enough elasticity to alow for the thermal expansion of the head and other components. With alloy heads, especially, there have been failures of the fasteners and/or block threads/material because the fasteners tensile strength was too high to allow them to stretch and so they pulled the treads or simply snapped. Sometimes it's more simple, with the head/nut's washers embedding into the head, reducing the clamping load and leading to head gasket failure - this can usually be countered by using larger diameter hardened washers beween the head and nut.

It would be so cool if you could order a banks built engine as a factory option from Chevy. I think they would sell thousands of them.

Please make these parts for the Older generation Duramax. This is ground breaking stuff

Peculiar bunch with the best toys

Random question. Can nitrous oxide be used in the exhaust to condense the air before the turbo

love Grandpa Banks!

In an alternate universe, I’m absolutely laughing my butt off to the fact that that all of our emission woes are cured by high-powered diesels.

Any Idea when the ram air intake for the L5P will be out? Cost?

are diesel rpm low enough to not worry about resonance in that single spring?

Since that's a engine designed for production truck, doesn't it make you concerned about the EPA? Where are you guys on the RPM Act? Your influence would be greatly valuable to save our race cars.

When is your programmer coming out for the LM2 Duramax. Sure would love it for my 2021 GMC Elevation?

I see those twin intakes and I want to see a compounding unit feed with T-Turbos

What`s behind studs being less forgiving than bolts? I really didn`t know that lol ).

Regarding the front pulley and balancing, are those 6 cap screws that hold on the blower pulley all the same weight in grams ? LOL

Man were can I buy some of this stuff these cams this man is smart gale come out with a duramax that dose away with the dpf for performance

I'm missing the Killing a Duramax and diesel monster truck builds. Plenty of people fabricating their own vehicles (and not to say you aren't adding your special engineering touch, which often lacks from the others), but nowhere else can we get expert understanding, explained in detail on how engines and specifically diesel engines work. It's fantastic. Not a fan of dropped vehicles so I kindof dropped the build series, but this video reminds me how much I can learn from you so I might have to go back through and find the interesting technical tidbits. I think I left off on the racing 8 lug hubs / spindles. That said, I've been sitting here frustrated with TTY fasteners as I do the clutch on my '03 Jetta TDI. To be fair, I think the only TTY bolts I'm dealing with on this job are on the motor mount and flywheel. I can understand that they have a lower spring rate (or if your steady state clamping force is lower) then it helps balance the load across maybe more than one bolt, spreading it out instead of concentrating the stress. Sure, they do the job. Auto manufacturers say they're cheaper for the same clamping force as well (less bolts required), and if you're building an engine the cost is the least of your concerns WRT these bolts. I just hate throwing money into new bolts every time, especially if I screw something up and have to redo. Not saying I do that often but the prospect annoys me. 😆 Plus one of the TTY bolts I pulled out on the bottom motor mount was heavily corroded due to the aluminum steel interface (and I'm sure some contributions from road salt, I ended up having to grind the aluminum motor mount out around the bolt just to get it out). I want to use marine grade anti seize so I'm considering torquing the fastener down dry but not yielding it, counting the turns, and marking the torque angle with a paint pen, anti seize it up, count the turns back in, line it up, and yield that SOB.

Curious..... if you were to ship this engine, complete, tuned, running, just drop in and go, what would the pricetag be as it sits?

The 🐐

What has got to be changed to reach euro 5 ? A dpf and egr ?

Studs vs Bolts: He is correct in general, but many blocks have shown plenty of strength on the threading in the block (an infamous GM weak-point), but not the bolts. A B-series Honda engine is a common example. Hence why some otherwise knowledgeable guys are a bit too eager to stud a block. Always best to know your platform, and sticking with bolts til you start lifting heads is a cheap strategy (if you don't take the head off often).

Hell yeah

can you please explain how modern Formula 1 engines are using such high compression ration, they are basically compression ignition engines? i heard a rumor they are using near 20 psi of compression and eliminate the need for spark plug use. is this true? what are the benefits and how would they control the burn? specially shaped combustion chambers and pistons?

36000lb towing as I'm sure you know but just had to compare. Is about a half loaded, by legal weight, semi box trailer. That's crazy capacity for a pickup style truck, even a 5500/6500.

Would you make parts for GM's new 3.0l I6 Duramax.

Banks takes one look at a factory Duramax. Then says..."Junk, this is junk too, this can also go...junk. Okay now that all that unreliable 1000pounds of emission parts mess is out of the way we can finally build a real Duramax engine". 😆 😂...Lol

16:11 I bet he was really good at the Operation game.

Gale, I’ve been watching your site for enough years and have learned so much about engineering, that I’m wondering if the Banks school of engineering will be conferring engineering degrees to your students. I need to know soon because I’m 72 years old and will need to begin my new professional career soon. Need to get enough years in to qualify for retirement.

I’m wondering why you didn’t use a big blower and lower overdrive off the pulley. Are you concerned about belt slip on the small upper pulley, there’s a lot of surface area on the lower pulley, but not a lot on the top

The true test of a company is how they pull together to make a deadline... I cant wait for SEMA Gale....

I don't know but if I'm going that deep in the engine, with a blower, I would want to hot torgue the head bolts and keep the head gasket. But what do I know...

All I have to say is good luck!

I want to see what you can get out of the 3.0L I6, greatly prefer an I6

What about Mike Wood out Wichita Falls. NOS nitrous oxide system

Love this series. And the others. What would be the price of this engine set up? 30k?

Could the nitrous delivery system also be used for propane injection as this is a diesel??

I’ll take an emissions friendly tune so I can take the egr, dpf, and cat off my truck!

sooo beautiful

I’m a newb so bare with me, if you are changing to a head stud, it would be the same diameter at the thread. Would it not be torqued to the same value as set by the engine manufacturer? Or is it higher as set by the stud manufacturer?

I've said it for a long time .. THE SECRET IS IN THE TUNE...

Banks is really bringing a new configuration and new products to SEMA. This is not a cosmetic build. Obviously Lockjaw's appearance is not what the build is about.

Can this engine, like the Euro diesels, run reliably at 5-6.000 rpm?

first!!! glad to be here

I always enjoy your lectures.The young guy should listen to your teachings. In the old days they said to pump more fuel into it for more power. Smoke was king! Makes no sense wasting fuel . in the old days a supercharged 2 stroke aircooled diesel powered passenger buses leaving long trails of Oil and Fuel Smoke. Cough cough. Eyes watering. Passengers dieing from the Hydrocarbons and Carbon Monoxide. I would Vomit from the fumes.Full sulfur diesel fuel. Mr Banks could I use your company name to get into the show? Tell them the CAT wants to inspect.

Clean tune? The Euro 3 emission standard is 20years old and compared to current standard very easy to fulfill….

How much are the 2004 durmax motors

“In all our Duramax programs” He is the illustrating the possibility of thread failure due to the rigidity of head studs. I listen to people with more experience than me and draw my own conclusions.

How much to buy a high horsepower off-road use LP5 with an Allison transmission that can handle it? I think it would fit perfectly in my 1970 C-10 Chevy short bed

Piece of cake

Does banks sell the stuff he takes off for less Incase someone else can use egr and other stuff

I wanna put this in my 1990 suburban.

How much for one of these??

Woot

In regard to the emissions, I know in New York State, doesn’t matter the year of the vehicle, the year of the engine matters. The engine needs to meet emissions for the engine year if it is to be used on the road. At least that’s how I understand it. A 2022 engine in a 1950 needs 2022’s emissions. In reality, we should be tuning all cars to pollute less at all times because when it’s running correctly, there is minimal pollution anyway

I absolutely love the approach to tuning that beast! Yes, with all that forced induction, you definitely could run a super clean and powerful engine because of thermodynamics and make it more efficient. Not like alcohol in gasoline, or ethanol rather which requires more fuel to do almost the same amount of work while making carbon deposits which robs an engine of thermal efficiency...

I feel like gale would be the guy to make the breakthrough to a no emissions engine that burns as clean as an emissions one wouldn’t that be something!

Emissions just makes particles smaller and harder to get out of lungs

Gale: "Thats just my experience" mic drop...

Why does Gm not use electric fans with PWM Controllers for Duramax powered vehicles.

ah the euro 3 label my workvan got that label but my 92 caprice has a euro 0 label xD

Bring on SEMA!

I’d like to have that engine in my truck lol

Watching this entire series for the first time over the past few days. Question, have you considered using the factory HVAC system to flow Freon through the intake/charge air cooler to super cool the charge? Awesome work Gale. You rock.
