WAY more happening (and not happening) in dampeners then I'd imagined. Banks blessed us once again
Thanks for watching. Please share friends who will appreciate the education.
"Back to school with Gale Banks" Thanx for the lesson.
I don’t normally comment on videos but this one is very deserving. To Gale and the production team, my hat is off to you. You guys do an excellent job of explaining the physics of how engines and power adders operate. It’s great to see experts building engines properly, not just bolting on parts aimlessly. I’m especially delighted to see the caliber of testing equipment utilized in the shop and the dyno cells. It’s great too see the spread sheets and talk numbers while Gale gives in depth explanation to their findings. The Duramax video series have been especially interesting. It’s very refreshing to see that efficiency and fuel economy are so important to the Banks way of doing things. Thank you Gale and the rest of the team for posting these videos and teaching people the right and informed way to do things!
I could watch Gale Banks talk all day. It is wonderful to listen to someone who follows the scientific method and applies it to automotive performance.
Dang I wish Gale would implement an "Adopt a Nephew" program!
Come up with a revolutionary idea and you never know...
@@timothymroberts2949 That's not so fun. I just wanna borrow some of his cool rides!
@@kmcwhq for sure!
I've left messages to all the popular Duramax TH-camr's after you pointed out this Fix, none will take it seriously?! Thanks for making this Video!
Which ones?
@@cencoast_7.340
Probably the ones that already know it all and have a multi million dollar testing facility in their garage.
Thank you very much Mr. Banks! I've always known what a Fluidampr is, but I've never heard a real in depth explanation of how and why it is so far superior. You are a wealth of knowledge sir, thank you for sharing with us!
How do we know this? : because we destroyed one ”he said with a smile on his face 🤣🤣”
Time for me to learn from the master. Thank you for making me smarter.
"It's coming out of the oil hole." I've always loved this guy!
The setup is what sells it. "I can already tell you where it is leaking from" X)
I could listen to you talk for days. So much knowledge... Thank you for sharing your experience with us. I love seeing how excited you get about new shinny parts😁! You are awesome!
Thanks Gale. That is at least 40 years of blown up engines learning you just passed along. An excellent course in crankshaft torsional harmonics . I hope you do a part two on the fully counter weighted crank you showed allowing the reduction of whipping (jump rope) of the heavy end counterweighted stock cranks Effect on the main bearings and main bore failures where some have ripped the main bores right out of the block.
Screw the Tiger King...this guy is the Diesel King!
Love these videos, i always learn a lot.
I had a vague idea how a damper worked but this explains things so well.
Why is it that you never lose a step through all these years ? You kind of remind me of the famous Astronomer & Astrophysicist the late Carl Sagan in that you have this ability to convey the very difficult to the layman with perfect clarity. It is rarefied air to be sure. Have not visited your shop since moving to Arizona but , perhaps, one day again this will happen. I really appreciate your passion and dedication. Please do not change a thing as your videos are informative, educational and mind blowing. So Thanks Gale for sharing your fascinating world with the rest of us. When I buy another cetaner I will be back to load up on the good stuff. Until then say safe and be well. And please keep these videos cpming.
Thank you for sharing what you know. I haven't seen anyone else explain these mechanical principles like you do. I love learning from you
one of the best informative vids yet, stay healthy gale,that built in reluctor is nice
Love watching the process of making a truly functional setup.
Yes, talk nerdy to me! I subbed for this- HP Academy does this too. We need more of it!
Excellent explanation. After exhaustive research I chose a fluidampr for my engine combo over the far more commonly used aftermarket elastomer dampers, having this video would have reduced my research to about 29 minutes.
Id love to hear Gale's take on aftermarket elastomer and pendulum type dampers.
Always learn something knew! Love these videos! Love Banks products!
I was told by an automotive engineer that MOST mechanical components are COMPROMISES! The most for the cheapest. A lot like the NASA space program. I have been using a Fluidamper for years on my Race car & I'll tell you it's an excellent product & well worth the money! Good job Mr. Banks & keep up the great videos!
Always a treat to watch your vids. Info not available any place else ON THE PLANET. Thank you.
Well it is , but you usually need to be there to hear it from the knowledgeable person😁
Been binge-watching Gales videos lately and I‘m always amazed of his extensive knowledge of seemingly anything about engines
Wow, Gale knows SO much more than I’ll ever forget!! I learn so much here, keep up the incredible work!
Best engine / Engineering demonstration I've ever seen. Excellent conveyance of what goes on in the engine. Want more Gale!!
your videos are so informative! I've learned more about forced induction watching your videos than from everything I've ever read on the subject. I had no idea what the damper did for a crank. THANK YOU for taking the time to enlighten us! your knowledge of performance diesels is AMAZING! I look foreward to the next installments of the killing & building series!
Awesome video! What great information and great visuals. Thank you Gale!!!
Thank you Mr. Banks for all these useful informations. It is always a pleasure to listen to you. Experience is exuding from your speech.
OMG... Gale can't get enough of this. Awesome explanation of physics. Please keep this coming! Great video!
Mr. Banks - You are an excellent teacher/engineer and these lessons will live on for posterity. Each and every video is appreciated by those of us who like you - just want to improve or make things work better (or how they should've been made in the first place). Thank you for taking the time to explain, test, and prove everything you do.
I am fairly new to this level of engineering but I will continue to learn from previous and future releases. Can'y wait to watch this entire series and whatever comes in the future! Loving every moment!
What an education- I learn so many different things from Gale.
Lesson learned, thank you Gale Banks !
I feel like I’ve gotten just a little bit smarter every time I watch Mr. Banks explain anything! If anything deserves to be pay per view, it’s these snippets of genius combined with a lifetime of experience. Thank you, sir!
Wow. I feel like I'm back in school with processor Banks. Great teacher! Fluidampr will definitely be my next upgrade.
Bravo on your damper class !! I've understood all you said for many years, but have had a hard time explaining it to others ..great job!!
Liquid silicone absorbs vibration better than rubber....seems simple to explain.
Great video on the operation of dampers with no sales, thanks Gale!
Thank you so much for sharing your expertise with us even though i am a RAM man i follow all your projects keep up the awesome video/vlog God-bless and stay safe in these troubled times
🙋♂️🇬🇧
Great video. Love the education of actual applications! Not just theory and formulas like you get in dynamic systems classes in college.
Great info Gale keep up the giving the average person hope in understanding
Gale, I've been doing a bunch of homework on crank harmonics and dampers lately, and as usual you've taken us all to school and learned us some things! I didn't realize how significant the difference in frequency spectrum (or as it'd be called in audio, Q) was elastomer vs viscous. I'm working on building a cheap turbo amc 4.0l I6 for my project car, for right now I'll run the stock damper. Hopefully for a street car it'll be okay seeing short hits and maybe a few drag passes. Seeing that elastomer separate, I realize I now have an indicator to look out for as to how well the factory damper is surviving!
I did, the day after my warranty expired and 125,085 miles (125 warranty), I had just hem hawed about extending it for another time period with GM, and said I’ve taken such good care of this truck, it runs like new, and is just breaking in! Hung up, after agreeing to consider it and call back the next day, stopped to pay the toll, eased out of the booth and hiccup hiccup BANG! Injector stuck open loaded the cylinder up under light acceleration, wish I had-known about the recall that hadn’t been released as of then, until I opted to sell the truck.
With the "killing a Duramax" postings, you made a knowledge magnet with the experience presented. I meant by magnet as reading in the comment section. There is a lot of information. Without Mr. Banks effort, nobody would bother commenting. Very grateful.
The presentation lets the audience visualize what is normally written in papers and it is more like an education with hours and hours of laboratory time. The quality of delivering the knowledge is outstanding, I meant initialization, motivation, result and approach of the idea. It is better than most classes that I attended. Shall we call you professor Bank.
On the crankshaft breakage side, I thought of an idea of utilizing the crankshaft sensor to measure the crankshaft twist with respect to time, and from then, get the torsional vibration analysis. The idea is using the back and the newly fitted sensor in the front and subtract (or multiply) their output using analog electronic circuit to get exactly what the twist angle is. Just thinking, Also could you please tell what is the amount of twist in there.
Thanks.
2👍's up Mr power thanks for taking the time for us all
So much great knowledge imparted in this video. Thank you ever so much.
Thank you. I finally understand how these really work.
Great in-depth explanation! Thanks for sharing
Never had any idea that part was so important. Thanks for explaining.
I used to be a Powerstroke guy but seeing how Banks is having such a difficult time, week after week, killing a Duramax I'm switching to GM!!!
Sales are strong for GM in Q1 in point of fact.
Couldn't pay me to own a Navistar engine. Drove them too often professionally.
I would take the Isuzu #1, then Cummins, then gas, then Navistar. I am not a fanboi or hater of any truck brand, but engines? Little pickier.
Longevity....that's the key. I have yet to hear any info on what they have done to fix the Dmax headgasket issue. Dealer....$10k without heads being checked. And every RPO code of Dmax has had this 1 common issue.
Unless they studded the L5P from the factory and upgraded the gasket materials. But GM loves to cheap out on fixes and rather band-aid something betting it will clear the warranty period before breakage
@@mikz86ta1 LB7-LLY had headgasket issues ('01-'05). They redesigned gasket in '06 with LBZ-LMM ('06-'10) and they rarely fail unless pushed. LML was another redesign in '11 which seems to have caused the head gasket issue to return. L5P? We'll see...
@@scottmcfarland1110 oh ok. Yes we got a LML and just found out the HG are on the way out
Classic..... such a smart man to dumb it down for us to understand.... thanks for sharing your knowledge...
I am a mechanic. That is a proper explanation. I bet somebody edited out 20 minutes to keep it concise.
Que lo pelo, da gusto escucharlo!! Cuando uno empieza a entender lo que dice hay mucha matemática que toma sentido y ahí es cuando uno realmente sabe por qué se rompe lo que se rompe cuando uno modifica un motor para sacarle más potencia. Muchas gracias por videos así!!
Love this stuff, great explanation. I have a Fluidampr on my 65' deuce hardtop.
Mr Banks, you sir are a wealth of knowledge. Officially ranked as a National Treasure in my book. Excellent video and demonstration, thank you very much.. signed.. America. 🇺🇸
Wow always so info rich! Thankyou Gale! 🏁👍🏻👍🏻
Wow, I recently put a Fluidampr on my Cummins 5.9 based on recommendations in TDR. And the diamond washer with ARP bolts. Looks like a good choice!
Been looking to get a Fluidampr for my 12 valve Cummins for some time now and hopefully will be getting one this summer
Fluid dampner is not a good ida look at ati
I'm curious if you have ever thought about building a modern 2 stroke diesel with electronically controlled injection and modern forced induction? 2 stroke seems like a natural way to go, there'd be no need for an egr system because with a two stroke that happens naturally. Two stroke technology has grown leaps and bounds in dirt bikes but in diesel engines it seems like it has stagnated since WW2.
2 stroke sucks.
Only problem with 2cycle engines....very dirty...wont pass emissions regulations. Emissions is what killed the Detroit 2strokes. I am with you on the concept on of common rail injected 2 stroke
Zues Toots wrong. Old ones do.
@@timothymroberts2949 at least the old ones were...I'm sure they could design new 2 strokes with some electronic wizardry to make them run clean. But then that ruins what was so good about them. They were ultra reliable because they 100% were mechanical.
@@zuestoots5176 If that's how you feel then none of this conversation is for you. See ya later.
💪🏻💪🏻🇺🇸🇺🇸 Keep posting Gale!
I envy anyone that can support a family with a career in motorsports. I hope to be there one day
The man, the myth, the legend. How awesome would it be to sit with Gale over a coffee or a beer and just absorb his years of wisdom?
Wow: Whipple and Banks? Can't wait to see the final product.
Thank You ! You Just Saved A 7.3 P.O. For New Fluidamper In The AM
👍 loads of great information! Ps don't forget the sale on diff covers
Just amazing, thank you. 😍😍😍
GM was putting fluid type dampers on Detroit diesels before I was born, I would say they know the advantage but have made a choice to go cheap these days.. Good stuff you are talking about, great job.
Love these videos! Add some pendulum style absorbers to the crankshaft!
As an engineer and an engines guy, I think this is really cool stuff.
Dear Mr. Banks; BRILLANT video, especially at minute 20:00 the best demonstratiosn i have seen of a VD; i would like to see the same for a ruber ring VD.
We need a banks power calculator that's where the magic happens
this is awesome!
As the owner of a 1982 6.2 diesel with a Banks sidewinder. Which btw is the only way to enjoy this engine that was engineered for fuel efficiency not being a work horse Cummins or what have you.
I’ve enjoyed the reliability and efficiency of this engine for years and the turbo makes a ton of difference!
I’m bringing all this up because I have heard that this engine has a crankshaft breakage issue. Well I have personally not had this issue but I looked into it a few years ago and it was a harmonic balancer issue. I believe something like putting a new one on at 100k miles and keeping an eye on separation at the rubber.
Just wanted to chime in and say also that my sidewinder is original and I have never had one issue with it. I do change my oil at 3k mi..
The packing department does an incredible job!
Gday Mr banks I dearly hope you live another 200 years I really do. You won't so I hope you pass on everything you know along with all your research. I have a friend that is 67 I am 45 . He is teaching me as much as he can about line boring and machining as he is scared of the knowledge being lost.
You are a legend in many ways . Good luck sir from an Aussie. Can't lie be cool to me you one day. Love from Aj in Aus
Everyone else has Netflix, i got banks 😌 im 6.0 owner i watch bill alot but im learning something that bill couldnt teach that this guy can. I learned about crank shafts finally
love your vids !!!
Very smart man.. drives me crazy listening thou. It takes forever for him to get to the point.
I prefer this to the shorter videos that are less in-depth and present the information too quickly. I have to keep pausing, rewinding and re- listening to get the information. At least I understand Gail the first time he explains it. The extra time allows it to soak into my less educated brain. Also, I very much appreciate the man's sense of humor. No love lost John, the important thing is that we're both trying to learn new things!
One can't get to the point instantly when explaining how each part interacts .
Just watched a video titled something like “most violent turbo explosions ever” lol as if they are proud of blowing up their engine. I have never been one to become a fan boy but the difference between the Banks approach to real power and others attempts to reach a mark for a split second is crazy.
Gale Banks and Art Whipple coming together for a project is going to be legendary
I've got a fluidampr on my 6.2 diesel with hopes to preserve the crankshaft.
Same on my 6.5 with the leroy diesel one piece pulley
@@detroitdiesel-vu3ig Leroy has the best price for one.
My family is all robots too! Glad to finally get that out!
Gale bringing hotrod science to the masses.
Bmw N54 335i also use a diamond washer holding the hub to the crank - but with zero keyway FYI :)
Very informative video. Am I correct in deducing though that the wide band damping effectiveness of the viscous coupler does come at a collateral in the form of energy (or BHP)? The elastomer damper - like a spring - would return the damped energy back to the point of absorption on the crank at the same angular direction, whereas in the case of the viscous coupler, the damped energy is converted into heat and dumped into the atmosphere. Did you manage to calculate how much energy is needed to run the viscous coupler throughout the entire RPM range of the engine? It might well be a tiny fraction of the overall power output of the engine, and well worth the cost in order to safeguard the engine components from mechanical harm, but purely from an engineering perspective. Thanks, George - Cambridge UK
I need one for my LML!
I always thought of it , like a shock absorber like in suspension, the damper does the same thing, only torsional! I was wondering if anyone tries a double damper, maybe one on the rear? I guess the clutch or converter will Handel the smaller amount of torsional viberations. Great video Mr clause hum, I mean Mr Banks!
The rear doesn't need a torsional damper. The mass of the flywheel or torque converter keeps the crank quiet. It's the free end that needs a damper.
I have the AMSOIL Bypass filter kit on my Dodge and I love it. I have been able to extend oil changes out to 20K miles. The replacement EA90 filter is $49 to replace. I was considering changing to a FRANTZ Bypass system because the media filter is only $5 and exceeds the AMSOIL filter. Thoughts?
I am wanting to unbox my own box, my new differential cover I’m waiting on.
and those crank harmonics are fed into the camshaft, which has its own harmonics. it's like a big bowl of elastic bands
Nothing wrong with a little minor surgery. Especially removing staples.
Good day. Thank you so much for the info. I want to ask a quick question. My crankshaft (big end journals) is machined to its last deck, should I be worried if it's going to last that long? Thank you in advanced
I was wondering if you were going to update the damper on your duramax, because you had stated you went past the stock engine RPM. But your stll using the stock crank. Nice explanation of the viscous damper....
Wasn't that the whole point of getting it, to put on the Duramax?
@bankspower
Any products you recommend for older gens? They have a much worse problem snapping crankshafts up front
Gale Banks for President!!!! Fix It lol
You know one of the first modifications I ever did to my car was an underdrive pulley. I almost bought the Billet aluminum one cuz it looked cool but then I read that you need a good damper... especially if you're going to rev it. So I got a good dampener. I now regret not getting that ATI racing one. I got one step down from that. It says it's good to 6500 RPM... I don't really spend much time above 6000.
The ATI dampener is a really good unit too.
With all this talk of "killing a Duramax," you sure are taking many steps to keep it alive! LOL
Joking aside, great vid.
I am sure he has a target HP number he needs to hit, and the mods are necessary to achieve that. How many coal rollers have even thought about the crank damper?
I think you have a good point. Goes to show you how good a stock Duramax is imo! There are fascinating refinements( *tuning* ) presented here tho. One way to *tune* an engine is to in fact record the noise and measure versus *expected noise* as I think is presented here. That's how the Japanese Brands do it anyways...and do that very well at stock I might add.
I think he said, in an early video in the series, that he was going to keep pushing it until they crack a block.
Thank you for this. Should I upgrade to one of these for an OE engine with no mods with a 106k miles? Or - should I just replace with a new OE piece. The difference is about 250$.
Yes but it seems that the fluid damper will only dampen torsional vibration? Is it possible that the rubber damped damper also dampens radial (bending) vibrations (movements "to the outide" if you're looking directly at the end of the crank) when the crank is spinning, where the fluid coupling does not?
From a manufacturing perspective, I'd like to know how they seal the tuned mass and silicone fluid into those dampers! The cut-away didn't appear to show an O-ring seal or any fasteners, etc. Do they just squirt it in, laser weld the outside of the case, clean it up and call it good?
The back cover is laser welded then the silicone is pressure injected through two fill holes on the back cover. Once full the fill holes are then plugged and spot welded.
Would the fluid damper be a major benefit or upgrade on a stock, or slightly modified tow rig, with a stock crank? Or would you spend your money elsewhere?
I wonder if this is going to be available for the Titan XD with Cummins?
