Gale banks is 81!?! Let’s hear more about this living legend’s life.
humm
@@TTGTO288 oh, never thought of that. He’s done so much, I think his people could make something fairly easily that would give a more accurate picture. But thanks for the recommendation, I guess 🤷♂️
@@TTGTO288🤓
For real though... Listening to Mr. Banks talking about engines is like listening to my grandpa talking about house construction. There's informed, and there's "I've been building houses from scratch, from making fittings and cinderblocks to wiring them, all by myself, and for longer than you've lived" informed.
@@michaireneuszjakubowski5289no disrespect but engines are far more complicated than houses.
I am always impressed with how Gale explains these complex things in a way that makes them understandable. Imagine if we had teachers like this in our schools.
There'd certainly be less ignorant replies in the horsepower/torque debate!
@@roberttammerawitchey4652 what would be cool if people could be educated and work together to push the envelope, like challenging ideas with your buddies to get better. Man, can't tell you how much fun and learning it was in the college and high school years working on cars trying to get the most out of them.
Fortunately, I had teachers like this when I did my apprenticeship in the early 90s, taught to make and build not just replace like now.
@@TimDoscher-wj6xh yessir.
Shows 💯 that school is NOT a place of “learning”… it’s a place of confusion, & Herd Group Think 🐑
This man has forgotten more than universities can teach... Thank you
@@TTGTO288 And when do we expect your vidio detailing the purpose and how dyno's work?
@@TTGTO288 Definitely understand, you're playing second fiddle to a sharp business man
@@TTGTO288yeah, you don't know more than him, you also have never come close to his achievements in life. You'd have your own channel or business that competes with him. You also wouldn't have the time to write comments. You're a loser, just like most of us.
@@TTGTO288 Who's the keyboard warrior? You've been posting your HalfAss454LSX

I used to run a diesel engine dyno at a shop i worked at.
Seeing that water heat right up and steam impressed me every time.
And there was hundreds of times, the boss was "lending" me and the dyno to a company that was developing replacement 60 series injectors.
It wouldn't take too long to draw down that 500 gallon water tank on a few extended pulls,maybe 15mins or so before we would have to back off and let it fill up.
And im sure i had plenty more to learn about it, but that was quite a fun job.
@@TTGTO288 we only had a 400 or 500 gallon tank ,and yes I never said the boss was a rocket scientist, so dump that crap and wait for it to fill 🤣
Whatever the hell drain the water was being dumped in , yeah it was pretty hot.
Always had condensation at that end of the room.
We had a separate little tower for the engine coolant/water
Let those words sink in. We measure torque & RPM. HP is calculated value.
I was about to rage reply when he started talking about measuring horse power. Dynos don't measure horsepower they measure torque. Horsepower is a derivative of torque and RPM.
Holy shit, horsepower is just watts... Thank you for this sudden realization! It's just like with electronics, the relation between volts (rpm) amps (torque) and watts (HP)! Like, power supplies even get rated by watts, even though you really need to know the voltage and amperage for your specific application
@@josephrumpsa180I think what the OP was getting at was that a large portion of people think that dynos measure HP. You seem to be one of the people that understands that HP is a calculated unit. I can't tell you how many times in car forums/Facebook groups this topic comes up. There is a large section of people that don't understand the topic.
You know I've wrenched on cars for a decade or more now and never knew how they actually get the HP numbers from. Never worked anywhere with a dyno and I haven't built any racecars, glad I learned something new today.
Yes, isn’t this common knowledge??? Power= (force*distance)/time
I was 20 years old when I bought my first oil burner. Came out of Wyo tech wet behind the ears found a good job and proceeded to put all this mans stuff on my truck. Man that thing was amazing and I never had all the smoke. I believed in the products because he makes sense. Awesome stuff always be a banks power man here.
I feel more informed on diesels and I don’t even own one. This channel is a God send!
Now I want to put a Duramax on my Civic
This is where an understanding of physics makes sense to people who are not afraid of learning the reasons things work the way they do.
I sure appreciate these videos.
Now, _BRING BACK THE TURBO KITS FOR THE JEEP 4.0L SIX CYL. ! ! !_
I had no idea they stopped making them. Bummer. I had planned to put one in my 04 LJ but had to sell it. Am still dreaming of finding one to rebuild someday, if my situation changes, and of course turbo charge it. Anyone else make a turbo for the jeep 6? Or a supercharger? Seems there would be a decent market for them, no?
Ok, no surprises there.
I wasn't aware of the 'anti-spike' coupling, but it makes perfect sense.
a short coupled setup, along with what appears to be a non-clutch (no disk with springs) direct mounted driveshaft would 'chatter' quite a bit without that absorber!! I'd bet that dynamometer has some serious test hours on it with his testing.
That's fantastic Mr. Banks. Nobody ever does a show and tell better! Thanks, G. Hames
what i would give to have a drink and just pick this mans brain... true legend. his knowledge of engines is out of this world
You want to eat his liver with some fava beans and a nice Chianti too? 😂😂
Phrasing dude
Love this dude
Great quick explanation of a Dyno!
@@TTGTO288🤓
In lamens terms. It’s a water pump with a sensor attached to it. Gale just bought the craziest dyno money can buy. That’s a beast
The fact that someone figured all of that out blows my mind
I don't know who this guy is but I love hearing him explain car stuff
Thank you, professor Gale!!!!!!!
I'd pay double the fee to take classes from Professor Banks .
I'm normally not a fan of modern automotive engineers l, but he is an exception!
Love to spend a year next to this brain.
I’m telling you this guy knows his sheet
She's a nice shinny new one I see! Go Banks!
This the free mechanics school u guys were talking about
I’d like to know a little more about how the hydraulic dyno works. I guess I’ll need to look it up. But thanks for the overview. I love these Banks videos
A Dyno like this is basically a pump who's output is throttled; it takes power to turn the pump but the throttled flow means that power converts to heat, so you cool it with water. I tested Huey helicopter engines 1385 HP. We used a 5,000 gallon water tanker as a water supply, water circulated back to the tanker.
@@robertball3578 that was helpful, thanks
I really enjoy this guy
1972 highschool Dyno was for small engines. It was water powered
It's similiar to what I'd imagined it would be.
Love this guy. I want to kno abt his 03 Marader
Mr love your Engine Engineering
I rarely say this to anybody, but you are a incredibly intelligent man thank you for your video, sir and please continue educating us troglodytes I am not being cynical. Thank you.
Look up " Proney brake " . Cheap and easy to build. Can be easily scaled for up to 300 hp. Great for smaller motors like motorcycle / snowmobile motors. Measures torque most accurately.
Sounds pretty straightforward.....
Love your videos 😊
When I heard "what does the Dino do". I got flashbacks of dinosaurs dancing through new york city 😂
I love your videos!
Looks like someone got a new toy
Torque. Yes. It all comes down to torque
And RPM
Well yes, because torque is twisting force and that's the engines whole job. Horsepower matters too.
Torque is meaningless without movement. Something can have massive amounts of torque and be static.
@@TTGTO288 what are you talking about, horsepower is measurable. Horsepower is rate of work, or rate of energy flow. Remember when Gale said the Dyno converts horsepower to heat? If you measure how quickly it heats up the water, you can measure the rate if energy flow. There are dynos that work like this.
Most dynos do not work like this because it's easier to measure torque and rpm and do the math from there, not because it's impossible to directly measure horsepower.
If you wanted to, you could also measure rate of work by literally making the engine do some work and measuring how fast it can do it. James Watt originally tested horsepower by seeing how fast the engine could lift weights.
@@TTGTO288 you retard, literally all forms of measurement are made up numbers. They just are what we've decided they are. This is like saying 100C is more accurate than 212F
Sure one is nicer to work with than the other, but it's the same thing.
I got lost at "torque arm" but thanks for trying to explain it to me 😂
Do you know Gale the way you explain stuff even the most non-car guy/engine person can understand what you’re saying and that’s really refreshing. Also thank you for calling it an engine !!! Bahahaha 😂😂😂
That’s a nice explanation and all, but it’d be even better if we could see the inner workins of the dyno, and a short explanation on it and the various components on the inside!! I’ve seen many, many vids like this that explain the overall “how it works”, but let’s move to the next step, which would be a more detailed, visual explanation startin at the dyno input!!! 👍🏻
@@TTGTO288 No shit, Sherlock…I was merely sayin it’d be nice to see a more in depth video on the inner workings of the dyno, instead of yet another video from a content creator showin the same thing all the others did…I’m glad you’re all over it, Captain Obvious…
It goes rawwrrrrrr
Dam
He’s a Genius
Are people really going to ignore the fact that all of this setup is just for a strain gauge?
Its funny how all the complexity of a measuring tool and it boils down to the first thing you learn in freshman engineering.
Its analogous to the complexity of a nuclear power plant, and it just boils down to the concept of a steam engine.
Once you know the torque AND the rpm you can compute the horsepower. FTFY.
Funny how small gas engines today don't even advertise their 'horsepower' on the recoil starter.... just the torque output.@@TTGTO288
@@TTGTO288you clearly haven’t taken physics, power is a fundamental unit of physics and engineering.
@@TTGTO288 that’s like saying you don’t measure torque, you calculate it by measuring the force and multiplying it by the length of the arm.
@@TTGTO288 U must not know much because by your logic torque isnt measurable either, youre just measuring the force and multiplying it by length of the arm. torque =fd,
@@TTGTO288 you do realize most dinos work from resistance of an electric field and measuring the resistance and increase in voltage and amperage right?
How is this device caliberated in the human machine interface.
Is it compared to a known accurate dyno to set up the set points. Or is the the torque measured mechanically at the strain guage and values entered as set points?
So will that dyno not work with my Honda motor or the reverse rotation motor for a boat
I wish Gale Banks was our president. Better health and knows what he’s doing.
Interesting
Now please dyno a 6.7 Cummins before and after installing your Monster Ram intake to convince me to do it.
Guarantee you a few people have and posted info/videos.. just check ffs
@mandelorean6243 I have searched and found no dyno #s. Testimonials yes but no dyno.
@BadAss454LSX It is not a cold air intake. It replaces a restricted heater grid and deletes a potential engine killing bolt associated with said heater grid.
@jeffrobinson1092 I've found one video, and they demonstrated a 4hp increase
ua-cam.com/video/F5qw1QnGByc/v-deo.htmlsi=tS6Lt5kgD25aS37w
Yup. Load cells don't like impact. That's why they use an elastomeric drive shaft
Is this the way all dynos work? Couldn't you use an electric load like a customized generator with a variable load to measure engine torque?
Tbh the use of a generator to measure loads will bring in too many factors to consider regarding the characteristics of the generator. Generators are basically electric motors, and they’re prone to lots of variables that affects the measured outcome.
An incompressible liquid and a strain gauge minimizes variable’s dramatically and allows a more direct measurement. Its so stupidly clever that I would’ve never considered such a basic method.
@@robster7787 I see your point. Classic example of less is more :-)
How exactly do you calculate HP from torque RPM and displacement
I didn’t get the heat part? Could someone explain it
@@TTGTO288 Thank you that’s a good explanation. So the water getting worked up is heating the strain gauge. How precise is this method for measuring torque?
@@TTGTO288🤓
So it is basically a miniature hydromatic on a bearing with a torque arm attached to a dead end tension link.
Better than a Eddie Current!
Once you know the torque AND RPM, you can calculate the power.
What brand dyno is that?
I hear mustang dyno ( not the car ) always read lower than others and is more accurate??
so jealous of all my friends who have the ability to understand any of these words
Can you measure horsepower from the alternator? Current volts torque
Not sure what you mean. 1 horsepower is 746 watts of energy. In countries that use the metric system they rate engines in Kilowatts (kw).
Torque into heat Gale, it's torque into heat.
Should hook up one of those hybrid motors to be a dyno, that way you can power the grid using the motor for regen... Might need a couple motors though, doubt one is ample enough to keep up with a Banks Built Duramax 🤣. But hey, at least you won't have to worry about Edison turning out the lights.
@@TTGTO288 oh, I know. It was a joke. You'd overheat the electric motor so fast, and the "regen" on the thing wouldn't produce adequate power.
Unless it's a Honda engine, which spins counterclockwise
Honda's older 4 cylinder car engines rotated "backwards"
Not all engines rotate clockwise.
Quantifies Power. Period
My Volvo produces all its torque from just under 2k, to about 5k. The dyno sheet is one nice flat line. I love torque
@@TTGTO288proper grammar eludes you
@@TTGTO288🤓
@@TTGTO288 well that probably means that you're loud and obnoxious or something. I don't haul ass everywhere I go. Every once and a while I might take it up to 3 or 4k but that's usually just to bring me up to speed or overtake someone
@@TTGTO288 my sentence brought more value to the convo than your many paragraphs of whining
@@TTGTO288 ironic coming from the guy who’s almost certainly liking his own comments…dyno isn’t reserved for supercars, get real.
What about brake horsepower
The foot bones connected to the leg bone, the leg bones connected to the……… 🤔😳😜✌🏽
Torque and RPM = HP
Strain gauge = Wheatstone Bridge.
How does that get calibrated?

An ELASTOMERIC COUPLING...HMM 🤔🧐. Very interesting.
Most Dyno guys do hard pull them shut the engine off????
The question is what does a Dino don’t… no wait… hang on
You need RPMs as well to compute horsepower.
@BadAss454LSX Yes, I am well aware as I spent nearly 2 decades of my career working with water brake and eddy current dynos made by AVL, Schenck and powertest. We developed our own in-house DAQs. Regardless, you still need Speed and Torque to calculate Horsepower.
@@TTGTO288 The point of my original comment was that Gale said "Once you known the torque, then you can compute the horsepower". Well, you need more than torque, you also RPM. In a video explaining what a dyno is and does, the audience that needs this explanation likely also doesn't know how to compute horsepower, nor that the typical dyno, controls and DAQ setup provides what is needed to compute horsepower and typically displays it as well as records it.
I always thought they were giant extinct lizards
Dyno do do
🇵🇬 ,,
Water Brake
me no entender
The only thing that makes sense is WATTS.
So the different elasticity in the coupler would be one reason that the same car gets different readings on different brands of dynos. Aha!
@@TTGTO288 🤓
Open it
I would like to Correct Mr. Banks in the fact that THAT is a Serious Dynamometer; in no way your typical Rice Burner Dyno by any means.....
@@TTGTO288🤓
A fine Zöllner, haven't seen one that fresh out of the box yet.
Gee and I thought that it was to prove that amateur’s could destroy a motor?
Torque is Real
Horsepower is a mathematical result
It turns horsepower into heat.
So we measure off of a strain gauge to get a torque reading in order to calculate horsepower.
Yeah. That makes no sense Gale.
I don't know what to tell you except that's how a dyno works. Your comment says more about you than Gale.
Well yeah, anything that moves creates heat and you're putting energy into an absorber (Dyno) that has to release the energy somehow. They're very accurate, and Horsepower has always been a made up number and that is torque x RPM/5252
bro doesnt get the simplest concept 💀
So its 20% power loss in thf car and 40% power loss from dyno🤣🤣
Why bother calculating horsepower, from the torque?
If you making torque, you making horsepower. Seems an artificial figure.
What about F1, huge revs(apparently huge hp), but next to no torque, struggle on hills.
Drag racing cars are all about horsepower. HP is work done fast. They need that number. It doesn't matter if their funny cars can pull a house, what matters is that they can turn all that torque and RPM into a rocketship down track. HP is everything to a vehicle that needs to go fast. Again, HP is the rate of work, but torque is the current load of work.

Why don't drag racers use F1 engines? What's the point of reving 20,000 rpm, if you can't get up the driveway?
What sort of houses you talking? Draft horses, don't rev much at all. How much can a draft horse lift in a given time, thorobreds were not used in coal mines.

If he’s wearing his pants that how it’s purely for function not form like everything else he does.
What about in gas engines when sometimes the HP is greater than the TQ? How is that possible if you need the torque to figure the horsepower?
So it’s a water pump with a built in heater ?😂🫣
