Killing a Duramax Pt 7: Spool is in Session! 

imagine how it feels to have Gale Banks tell you that you really know how to tune a diesel...Thats like getting a high five from dieselJesus

Gale is one hell of a smart man. He explains the physics and puts it in simple terms. Very interesting and great information.

He takes a life's worth of knowledge and shares it in it's simplest digestible form. The man is humble.

Next episode Gale Banks discuses quantum mechanics and how quarks apply to diesel combustion.

Gale sounds more like a scientist than engine builder . this guys knowledge is mind blowing and what a pleasure to listen to .thanks for another great informative video !!

Thank you, Gale, for sharing information with us, that cost you millions throughout your lifetime.

I could listen to this guy all day. He ABSOLUTELY loves engine theory and I love hearing about it.

Gale I'm so appreciative of all your knowledge and experience that you are willing to share with others. Alot of high performance guys dont want to share their "sercrets" so thank you!

god gave us you gale and it's a real blessing

The engine would have died of old age before they kill it at this rate

You know you're a Gear Head when you get excited when Mr Banks talks!

Smoke is like a fart... If you can see it, you've got issues.

I'm trying to figure out who gives thumbs down on a Gale Banks video. Then I realized there are those that still hate, steal kids popsicles, beat thier wives and kick the family dog.

Its amazing the amount of data you need to generate, consume, and understand to speak and act on what you think is correct and produce results. Amazing work by the team. Gale is also a very clear teacher. You have a gift of being able to teach several concepts, compound off of those concepts, and teach something that the viewer can understand. Highly entertaining and very informative.

WOW! If the EPA knew what Gale explained from 15:25 to 16:55, we would have clean, efficient diesels without EGR, DPF, etd.!!

I love your methodology and the way you cut straight through all the bs and hype Gale. I wish I could be your apprentice

Poor kory he was lost as soon as he said hello to gale.

giving us know how and entertainment for FREE, you're the best Gale, thanks, apply what you learn here and you can tune any diesel

Happy birthday, Mr Banks! I hope you do keep at it for another 20+ years! Great video, great info!!!

Thanks MR. power for taking us along with you for the great stuff

Ppei sales just went up by 150% by a simple handshake with mr. Gale Banks...an endoesement by a man this knowledgeable is a epic shot in the arm to your credibility.

This is bar none , the best channel on u tube so much information. .....thanks Gail .

I hope gale and his family is rich and comfortable! He's been thinking of engine efficiency for longer than I've been alive! Gale is awesome

I wish Mr Banks was making these videos his whole career. Very smart man. Love these videos

Do not worry Gale, you got a lot more years to go. Love your products that work as described. Keep up the great work.

You are an inspiration to all Gale Banks, Keep Up the good work!!))

KORY WILLIS !!! Love your Tunes in my LML

I was waiting on Gale to say something along the lines of " Then the fuel is injected into the cylinder with the air that is swirling there is a drag on the fuel molecules disrupting the swirl. " Next will be the novels drilled at an angle to help maintain or increase the swirl inside the cylinder. Great video Gale and team!

Such a beautiful shop, really classy stuff.

I LOVE THIS CHANNEL I WORK FOR GM ! AND I LEAR MORE HERE THAN IN THE GM CLASS

Telling a diesel combustion with onion. You are an amazing guy Gale :)

The science within it. True engine builder

Merry Christmas from Australia mr banks , please make our new year dreams come true blow the heads off that thing 🧨💣🔥💥 we are all students waiting , listening and learning. Thanks for your efforts in making all of your videos and sharing your plethora of knowledge. Cheers Tim.

Gale I love watching your videos. the details is what separates the men from the boys. who knew rolling coal and just cranking up boost was the answer. so glad your sharing your hard earned knowledge with us!

We are ready for part 8, like dang hurry up!

Aw, man! Another great video - but I hate having to wait for another completely captivating, and intriguing episode! I wish I could go to Banks' School every day and just keep learning!

Unleashed Duramax Tuning for the WIN!

I just hope you have someone as passionate as yourself to take over the torch when you retire. Would love to be able to be that person. Well we can all dream the big dream. Keep on making things happen Gale. Peace to you too.

Best videos on RU-vid

For someone like myself, that doesn't wrench on a regular basis, I still find this very intriguing and very easy to listen to. No bro science, just passionate discussion on a topic that is essentially the life's work of a man with great enthusiasm for what he does. While I am not a big "science nut" and I rarely can pay attention when I see a discussion take place in a shop where I could literally eat off the floor (I am a big fan of Sloppy Mechanics related material), this man has my full, undivided attention. At the risk of sounding disrespectful, he reminds me of my friends grandfather, an engineer and a very humble man I had great respect for that taught me some amazing things when we were kids. Not sure who would thumbs down such a video, I suppose you have to take into account accidental clicks and, of course, the ever-present morons of the internet world. I know this video made me subscribe.

Hes sharp as a tack! Better every year!

When Banks speaks suddenly everyone else seems like they are in first grade. The man is a legend.

This discussion on Data,.. is like sitting in one of Claude Rouelle's "OptimumG" chassis tuning seminars, and having your eyes opened on how much data is available if you understand the math from simple sensors placed appropriately.

Always very interesting Mr banks 😬👍🏻

I love this stuff! I would sign off on cloning one person and one person only and that person hands down is Gale Banks.

To kill a dirty max ... all ya gotta do is just like ... look at it 🤷🏻‍♂️🕺🏻

Lost count of the word “Right” But I was able to count “Ok”, “Exactly” and. “ Yes”.

All this talk about getting cold air into the engine and making power reminds me of some discussions I've had with guys about fuel efficiency in an engine. I've always been of the school that cold air in is still the most efficient, even at partial load. If you're decreasing the density of the air coming in via the under hood temperature, you're making less power at a given throttle and displacement. On my little 4-banger Saturn that I was experimenting with at the time, I looked at the exhaust and the intake systems on that thing and I could see that the major restriction was on the intake side. They were running a pretty big exhaust and a decently designed cast header for the size of that little 1.9L, so I put on a cold air intake to uncork a few more horsepower. At only 2300 lbs, that thing would scoot pretty good, and was certainly as fast as some heavy V6 cars with twice the power that my friends had. A nice side benefit is that I had a 4-5 mpg increase city and almost 10 mpg on the highway by simply slapping on a cold air intake that grabbed air from the fender well just in front of the driver side wheel. I was probably helped by how well that intake flowed, especially in city driving with frequent acceleration events, but I feel that at part throttle like that, which is where your highway mpg comes from, you're not really limited by that intake tube at all. That cooler air was doing all the efficiency gains in my opinion. Now the guys on the forums and my friends I was discussing this with at the time all thought the opposite, that warmer air would be more fuel efficient. I think they were confusing warmer coolant and oil temps with warmer intake temps. Warm intake air is inefficient. Warmer coolant and oil just makes the engine spin more freely, which is why the OEMs do it. It ekes out tenths of an mpg and helps them hit their CAFE standards. You know what I don't see any of the OEMs doing these days, building out fuel-efficient power plants that draw in warm air. They all have cold air intakes right from the factory.

We learnt today thanks Gale

That man is a true gentleman . A nice contrast between the ages .

Phenomenal series. Keep em comin!

I've tried to explain to people how having the best flowing heads isn't always the best on a carbureted gasoline engine because the fuel doesn't stay mixed as well if the flow is too smooth. Now Gale explains that it matters even when the fuel is injected into the cylinder under high pressure.

You need to build a two cycle diesel engine. One blower + two turbochargers. When this engine is at 5,000 rpm. The engine will sound like 10,000 rpm. Plus it will move twice as much AIR. TWICE the AIR, TWICE the H.P.

I wish I could buy Gale a beer or 20 and just listen to his stories.

Dang, you've got me hooked, Gale. I can't wait for the next episode, and I'm not even a diesel guy, haha. I am a data junkie too, though XD

I don't know why he has these guys in his videos all they do is just stand there and listen and look lost.

Lol why isn’t this episode just called - “iDash Infomercial feat. Kory Willis”

Kory looks so small next to Gale lol caught me off guard!

Spearco produced coolers and graphs suporting their capacities, my years usung them they were pretty much bang on also a USA company owned by Turbonetics.

i like discussion recordings like this. very cool.

I'm Watching Mr . Banks. !! I'm waiting to see what part brakes first. Lol. 🙏👍🇺🇸

Been watching this series the whole way, i wish yall would do some more 6.5 stuff theres little aftermarket behind them, but we have someone that built a turbo specifically for them that makes em respond a lot more, id love to see a built 6.5 IDI that the crank wont be thrown on the ground. Everything would have to be strengthened

loving the knowledge but can help to kinda think this series is just a long commercial trying to sell me a datamonster

The suspense is palatable

I heard Gale talking the basics of physics while Kory nodded and said right.

LUCKY 7's 😆 ALSO the 7th episode.

I hope Mr Banks has 50 years ahead of him, at least. Lucky Number 7! Any idea how many emails he get each day? Must be hundreds. No answering all of those.

Thank you for another great video!

Dang! Gale banks is a giant!

There are interesting fuel injector designs that have sonic transducers to help vaporize the fuel as its injected, I wish it would get developed and mainstreamed

13:35 the way numbers can come up and match at different parts of life is mind blowing. right now 777 likes!!

At age of 77 Gale is one sharp cookie,,

Gale Banks you keep teasing us.

I bet he's really great to work for

The only thing I can think of that missing in Gale’s videos is the token large breasted bomb shell that discretely walks around the shop with exposed cleave to help accentuate a talking point. Suggestion - As Gale is describing ambient air pressure, temperature, pounds per 1,000 cubic feet and their indelible affect on engine performance - the token busty could hold his pen and point to the engine pieces that contributed to the video outcome. Just a thought...

Truly inspiring I love this series. Im a data monster too.

Mr Willis is the man when it comes to this stuff. Build a Cummins gale and get Ryan Milliken in there.

He's apparently gonna talk it to death

Love it keep at it Mr Banks!!

I would love to see a series of killing a duramax 3.0 and see the longevity and what power potential is has with a proper tune

Mr. Banks I love the Dmax always have, your builds are incredible. Can you please please do a build up of a 5.0 V8 Cummins!! Alot of potential there and I feel like your the true person to see what it's fully capable of and still having fun with the little motor !

77. Wow! Good for you Gale.

Tfl truck does tow testing up the Eisenhower pass

back in the 70s I worked independent 2 way radio design, installation, maintenance, optimization(picking up crumbs). What I said at the time Motorola gets to eat the cake and we get the crumbs. But, sometimes Motorola is so slothful they sweep the whole cake off on the floor and we get the whole cake.

ive been told you want equal pressure or more pressure on the exhaust side of the turbo so the turbo dosent stall/cavitate with the resitance of intake side

You are such a TEASE!

Another great one.

Wow. Not only is Gale Banks one of the smartest men on Earth, he's also one of the tallest!

Why would it be theoretically impossible to have a 100% thermal efficiency of an intercooler? Correct me if I'm wrong, given a large enough intercooler (not practical obviously), you could exchange down to the point that the charge air is the same temperature of the cooler's external airflow. If you want to get nitty gritty, pressure drop would actually help thermally since gasses absorb heat when they expand. If you had a very small pressure drop over each inch of intercooler tube (let's say 0.001 PSI), even that slight expansion of gas would absorb a miniscule amount of heat. Granted, pressure drop across the intercooler would decrease air density coming into the cylinders so your overall efficiency would go down, but I'm still stuck on the statement that it's "impossible" to cool air to ambient across any intercooler.

It's been good, it's just better!

I am pretty sure PWR would test the efficiency of their intercoolers. They Make intercoolers,heat exchanged,oil coolers and Radiators for almost all forms of Motorsport. Formula 1, IndyCar, Nascar etc.

I am wondering why you're not putting the cooler "chiller" on the intake side of the turbo too. It seems that would give you more density and less heat produced by the compressed air from the output side of the turbo. Esenchaly making a cool day effect. IDK if I will ever see your response or if you will even read this, but I sure would like to know.

Idaho rob are the best tunes

Please, please, please Gale, take a look at the new 3.0 Liter diesels, coming out, in the light duty trucks. The Big 3 have done a good job, but I know, you and your staff can find us more efficiency. I would bet the "Bank" on it. (pun intended)

Damn I like these guys

I love his sample size of 1.

With typical air to air intercooler it impossible to get 100% efficiency, but water to air intercooler filled with ice probably will break 100% efficiency barrier

Interesting. I was looking at that Audi 4.0 twin turbo with the electric low rpm RAM air system, seems they're a little ahead in the diesel power business.

You should look at the Volvo Wave piston that's a recent take on pistons for diesels.

I’d love to talk to gale banks about diesel performance, especially on a Cummins engine, I’m sure id learn more then a thing or 2, on any of the engines (3.0, 5.0, 5.9,6.7) or even the larger truck engines like a 13 or 15L
