I really appreciated that last bit; we hear a lot about Munro, but never really get the tour sort of speak. Even if they considered that a "commercial" the work and effort they put into showing this stuff off like they've never done before deserves some reward.
It's definitely a commercial. Monro has a platform. Part of having a small business like his is sales. If this helps bring businesses to him, then great. He's letting people know he's open to work on their projects. This makes him feel uncomfortable, and I get it. But I like that it makes him feel uncomfortable. It should. That is a sign of old school integrity right there.
Thing is, my grandma’s meatballs tend to make considerable noise vibration and harshness a few hours after consuming them, however you could power an internal combustion engine with what emerges.

To those of you who have asked about the golf ball. The material is E.A.R. from Aearo Technologies LLC (company now owned by 3M). earglobal.com/en/aircraft/
I've never understood why *the biggest enemy of a battery is cool not hot.* I've always thought while once used as motive power heat is what degrades efficiency of a battery and not an excessively *cool*(by temperature) battery. Having been a snowmobile rider in my past life I can speak with Authority on the value of *active cooling*(running a 2 stroke motor through snow) as creating an enormous benefit to engine efficiency in point of fact. And I think a *note* on energy efficiency is always worthy of discussing as the idea that a two stroke motor is *energy inefficient* relative to anything is plainly false. We use to drag race stock snowmobiles against tricked out motorcycles in Florida and blow them away all the time way back in the 1990s before everyone caught on to the obviousness as to why that was.
@@doolittlegeorgeI think he may have been referring to the cool as the biggest enemy in the context of efficiency as turning on the heater can draw almost 8kw on the Model 3.
@@doolittlegeorge The optimal temperature for most Li-Ion batteries is around 35C. Significantly higher temperatures may be dangerous, cells can get damaged. Anyone who knows chemistry, knows that most reactions slow down in lower temperatures, that's what happens to batteries too. A cold battery (approximately under 10C) loses some of the capacity AND is slowed down, meaning that it can't charge nor output energy as fast as at 35C. These problems will be solved with new battery formulas soon. PS: gas engines have nothing to do with efficiency. Most of them create more heat than rotation, except for those weird rotary engines from Mazda, which can reach 50% efficiency.
@@charanaa3023 Looked and bounced just like a normal minigolf ball. A solid plastic ball bounces minimally, that's why it's good for minigolf with obstacles and banks.
I was surprised that there was no comparison of the Y's sound deadening relative to the Model 3? There have been some anecdotal reports of the Y being quieter. Did you see any evidence to support that?
I think the comparison should be taken with a grain of salt. The Model 3 Munro analysed was a pretty early production model. So all comparisons are a current Model Y with an old Model 3. Model 3 got a lot of tweaks and upgrades since then. So one should not say "Model Y has this and Model 3 doesnt" or "this is different between the Y and the 3" just based on these videos. We dont know if the parts are also changed on current Model 3. Still nice to see what changed in these years.
@@DavidHRyall the downside of that decibel meter is that it only tells you about the loudest sound, it doesn't tell you anything about the sound in general, so whatever sound there is may be almost as loud but there's less different sounds to be heard. making it sound much quieter. also certain frequencies can be very annoying to (different) people as we're more sensitive to them. hope i'm making some sense here as its sometimes hard to put what i'm thinking into english
@@Derpy1969 The Ford Futura on which the Chuck Barris Batmobile is based also had a slanted radiator. How do I know? Because I talked to the owner of one while it was cooling down after overheating on the side of the road.
Tell us more about it :) Sandy talked about finite element analysis. Are they any other way to figure out the location where it would be more efficient?
@@Findalfen Big flat areas like the other person said. Sandy called it "drumming" because those large areas really move like a drum head. Basically you run analysis, find the hotspots, add damping and mass into that area (which is how you approximate these sound deadener's effect) and show what the difference.
@@bassrover5925 It takes a bit more, especially when talking mass production. One thing to keep in mind is that an even coating of that stuff is nearly useless. You then still have the exact same drum, it just takes a bit more energy to get it vibrating. Instead you want to capture the specific frequencies it resonates at and convert them into heat. You can see this nicely on the trunk where there are 2 triangles. Those cover a wide frequency spectrum, dampening the metal's vibrations at those frequencies.

Dear Sandy - Greetings from the NHS secured UK. The original use of the acronym NVH was (at least in the UK) in about 1967 (a bit before your time I guess) with the release of the first Ford Cortina. NOISE - VIBRATION - HEAT. Please correct me if I am wrong.
"I get back at people".... Never try to get one over on an engineer. They are waaaay more creative at getting back at you than you can possibly imagine.
As an undergraduate engineering student I can confirm this. I don’t fuck with anyone unless they’re assholes to me or anyone else. Then I get creative lmao
We need to go change Chilton's and Haynes diapers :) great work man! Edit: your comment about cold for batteries. Please let Nissan know this. Well below freezing they let their cars charge. Heater for batt comes on at -14F. Manual page number EV-20. Btw, Quoting art of war was a nice touch...
Other carmakers use those, sometimes called STUFFER BLOCKS. They block airborne noise moving between compartments. Other materials used are squishier, resembling pillow stuffing.
We would definitely consider it, Sean, but we'll obviously need to look at the business case and reach out to customers to try to get a feel for whether or not the demand to purchase those reports is there.

Thanks for tuning in!
@@MunroLive I got an idea, tear down a F-35 and tell them why there wasting so much money on making that crap that can cost a lot less. Look at what SpaceX did, any lessons for NASA and Boeing to stop wasting money?
Will you be able to determine if MY has 5G antenna or ability to communicate with Tesla satellite network? Thanks for your work and videos. It is very interesting to witness from my dining room. You left us hanging on the deading material in golf ball. Where is it being used or where do you recommend applying the material?
Jk Ia it doesn’t have either. It does have a cellular link but it’s only 4G LTE/3G. It also has @ 2.4 and 5ghz WiFi antenna. The Starlink antenna will be as big as a pizza box with a motorized articulating mount so that it can steer the beam to whichever satellite it wants/needs
pilatomic that won’t be sufficient. The articulation won’t move very far, maybe 0 to 5 degrees in each axis but I think it will require both that and an electronically steerable beam
Please do one of these on the wind noise on the Tesla Model 3 and Y around the frameless windows and the gap in the roof panels, it drives me crazy and would love to see a Munro explanation and even better a Munro aftermarket solution that I could buy!
I was going to buy 10 copies of the Model Y breakdown until I found out it _wasn't_ 56,000 pages... I couldn't possibly stand to read a breakdown that was shorter than that. Holy HHHEEELLLL :)
My model Y still has noise and vibrations. Tesla recommends the tire pressure 42psi. I find it to harsh and stiff, I put the tire pressure to 35psi it a lot better but stiill vibrations.
great to get a better insight into what Munro & Associates do. I'm really interested to find out if Tesla are putting more of the new parts from the model Y into newer model 3's.
What are your thoughts on Tesla being able to retrofit a foam housing around the compressor on Model Y's already in the wild? Will a tesla tech be able to fit one on my car or would that be a tough job requiring partial octopump removal?
Great question! It really depends on how the part is designed, but it can certainly be done in such a way that it can be added without having to remove refrigerant lines. A "clamshell" type design with slots for the harness and lines and either a velcro or snap-fit fastening mechanism should work. Thanks for tuning in!
I once read an article (sorry, the source is long forgotten) that described how, at the same NUMMI plant in the late 1980’s, disgruntled workers would put empty bottles, etc. behind the door panels to create rattles. 😛😝😀
@@chstra45 But not just for road noise. IMHO it's place was determined by the sound tuner, who did the speaker & subwoofer tuning. Likely a bass absorbing tweak.
When I was an auto mechanic in the mid 1960s One customer had a new car that would make a horrible drumming sound at unpredictable times. After spending untold hours looking for it we finally narrowed it down to spot on the firewall. We fixed it with one mighty swing of a large ball peen hammer. The resulting dent changed the resonant frequency of the panel and the problem went away.
My old Chevy Silverado had foam in the panels at the back of the cab. It held moisture and contributed to the body rusting. I wonder if that will be a problem in these cars many years down the road?
Shouldnt be a problem IF the paint is good and the moisture has a way of escaping My 85 Chevy had foam under rubber floor mats so moisture would sit there and rust the floor Good thing I noticed that before the rust got too bad Threw the foam away and put normal breathable carpet in problem solved My 08 Silvy has ruberized coating on the floor under carpet so water dont hurt it
excellent work Sandy.....one thing to do the work, entirely another level to Explain it for lay person, I now appreciate Elon's comment "manufacturing is hard".
@@SolvingTheMoneyProblem its usefull (cheap, lightweight, easy to install and effective) to fill a void and affect potential resonance frequencies, people are saying their newer model 3's have them as well, so they must serve a purpose
Fabulous. An episode about Edward Deming and Toyota Production System would be awesome. This has been adopted by Silicon Valley under various headings : agile, devops, OODA. Given the amount of high tech hardware and software in a Tesla, this synergy / duality is critical for effective/efficient operation and manufacturing. I know you respect deming. Ben Sullins is a Tesla data science guru and would probably have further deep knowledge for such an episode. Just a thought. Great to see your viewers count soar!
Thank you for your explanation of what Munro Engineering does as its main business. You are at the heart of a successful capitalist economy. You can’t build a better mousetrap unless you know what others’ mousetraps are doing and how much they cost.
On my Mercedes SUV I took out the front plastic wheel well liners out and covered them in a layer of aluminum foil constraint layer, a layer of butyl rubber elastomeric layer, and another layer of metal constraint... Apparently doing it exactly like this creates a sound deadening layer that is as effective as an equal thickness of lead (which is incredibly dense). I also mounted the plastic on rubber insulators when I put them back on. It worked so well that I no longer could hear the wheel noise at all...not even above highway speeds with loud mud tires, or even spinning and shooting gravel. Btw my "metal constraint layers" were just aluminum foil tape, and my rubber is a membrane for sealing basement walls. It probably added a couple pounds. Now I've been in all sorts of vehicles, the over built w140s from the 90s (with like 6 inches of dense foam in the floors and double glazed windows in the doors) before MB got bought out by Chrysler and had many of the engineers replaced...new MB, Teslas, new f150s, Austin Martin's, lexus, BMW, Audi, etc... And not a single one has the nearly zero noise level that my amateur self did. I also went back and did the rear and now all I can hear is the exhaust. I also did my doors, but not so much to keep sound out but to keep it in and turn the doors into big speaker boxes to get more mid bass. It sounds amazing. Like nothing on the market. I really don't understand why manufacturers don't do more of this considering it's so simple and light and brings down loudly audible road and highway noise to utterly inaudible. I've heard of Audi putting a carpet like material inside the wheel wells to help dampen the frequencies, I was going to try that but like I said the road noise is completely totally gone. Like not there at 100 mph not there.
Great video Sandy! I do not mind what you termed a ‘commercial’ as it clearly shows how your company monetizes the outputs for your customers. I am curious if you and the staff provide specific training for design teams, quality assurance experts, college course work, or whatever to keep building good practices across multiple industries. Thanks for all you do. Stay safe!
Great question, Shannon! That is one of the many things that we'll be including in our final report. The stickers (red, green, yellow) that you see on many of the parts are our way of identifying whether a part is common (green), slightly modified (yellow), or all new (red) with respect to the Model 3. At this point, it is still far too early for us to give any sort of exact percentage, but once all is said and done, we will know the precise split amount. Thanks for tuning in!
Compiling what has been said so far: => Are the same: 2motors + brakes Electronics (fuze box+battery pack) The central console (raised only) 2 front seats (by adding unpainted metal raise) => Model 3 possible upgrades to increase ur percentage by being the same : Heat pump (might involve increasing the radiator too the same) Wireing to pipe, plastic protection, reduce thickness The rear awsome bucket Suspension =>Unknown since teardown unfinished (or since he doest do the small part like the door) Lights Front glass panel Speakers (2 seams to be added to the rear doors) Middle console (is it the same raise console, r deeper volume space inside) => What is known will allways be different Chassy All the other glass panels External mirros Rears seats Under the front seats air-vents
@@MunroLive I guess many things have changed in Model 3 since 2017. I think that Mr. Musk mentioned that in just first-year, Tesla made hundreds of changes.
@@Kram668 Vehicle controllers/PDC, or fuse box as you called, are not the same as model 3. There aren't wires in a pipe for the charger, they're busbars.
9:40 I very much disagree. Cold makes batteries inefficient and charging a cold battery can degrade it very quickly, but hot can cause stuff you really don't want to experience.
I think he was probably talking about the kind of cold and hot that we regularly experience from an environmental perspective, especially in regards to when you would want to use a grill shutter . As far as outdoor air temperatures and Li batteries, we see much more damaging cold temps than hot.

Jk Ia it doesn’t have either. It does have a cellular link but it’s only 4G LTE/3G. It also has @ 2.4 and 5ghz WiFi antenna. The Starlink antenna will be as big as a pizza box with a motorized articulating mount so that it can steer the beam to whichever satellite it wants/needs
@@SpiraSpiraSpira I'm almost certain it will be static, with electronic beam forming, so no need for articulated mount
pilatomic that won’t be sufficient. The articulation won’t move very far, maybe 0 to 5 degrees in each axis but I think it will require both that and an electronically steerable beam
Fantastic overview of what you do. Very interesting thank you.
That foam brick is funny. The last thing I would've expect for sound deafening materials in a car is simple foam brick lol.
I think that brick has serious meme potential. (They should have printed it with "companion cube" hearts, tho)
Tesla is doing a great job with the design and development of new models BUT they have a long way to perfection.
Very interesting insight. If I were in manufacturing, I'd hire you. Thanks!
Sandy-The uncle I never had!
Please do one of these on the wind noise on the Tesla Model 3 and Y around the frameless windows and the gap in the roof panels, it drives me crazy and would love to see a Munro explanation and even better a Munro aftermarket solution that I could buy!
new dreamjob:
foam cube !
Sandy, You're the man.
Great new opening. Keep up the excellent work.
learning a lot from you Sandy
I was going to buy 10 copies of the Model Y breakdown until I found out it _wasn't_ 56,000 pages... I couldn't possibly stand to read a breakdown that was shorter than that. Holy HHHEEELLLL :)
Hi Wot Nots - stay safe - love the show
My model Y still has noise and vibrations.
Tesla recommends the tire pressure 42psi. I find it to harsh and stiff, I put the tire pressure to 35psi it a lot better but stiill vibrations.
great to get a better insight into what Munro & Associates do. I'm really interested to find out if Tesla are putting more of the new parts from the model Y into newer model 3's.
What are your thoughts on Tesla being able to retrofit a foam housing around the compressor on Model Y's already in the wild? Will a tesla tech be able to fit one on my car or would that be a tough job requiring partial octopump removal?
Great question! It really depends on how the part is designed, but it can certainly be done in such a way that it can be added without having to remove refrigerant lines. A "clamshell" type design with slots for the harness and lines and either a velcro or snap-fit fastening mechanism should work. Thanks for tuning in!
@@MunroLive Thank you for the reply! Your videos help me scratch my engineering itch!
Literally no one:
Engineer at Tesla: toss a foam bock in there.
It's there for a reason. Keeps sound from echoing between outer quarter panel and wheel arch.
Cheap, very cheap to install, very light weight, effective.
Smart engineer at Tesla: toss a foam block in there.
I once read an article (sorry, the source is long forgotten) that described how, at the same NUMMI plant in the late 1980’s, disgruntled workers would put empty bottles, etc. behind the door panels to create rattles. 😛😝😀
How to drive an engineer nuts? Throw a square foam block into that space, who else would ever take a look in there?
@@chstra45 But not just for road noise. IMHO it's place was determined by the sound tuner, who did the speaker & subwoofer tuning. Likely a bass absorbing tweak.
14:41 My dream -- A Sandy Munro teardown of the Globemaster 2 (C-124).
I think you just found the Tesseract.
Mr. Musk didn't know where to hide it!... I mean Mr. Stark
Great stuff Sandy, keep up the good work
When I was an auto mechanic in the mid 1960s One customer had a new car that would make a horrible drumming sound at unpredictable times. After spending untold hours looking for it we finally narrowed it down to spot on the firewall. We fixed it with one mighty swing of a large ball peen hammer. The resulting dent changed the resonant frequency of the panel and the problem went away.
My old Chevy Silverado had foam in the panels at the back of the cab. It held moisture and contributed to the body rusting. I wonder if that will be a problem in these cars many years down the road?
Shouldnt be a problem IF the paint is good
and the moisture has a way of escaping
My 85 Chevy had foam under rubber floor mats so moisture would sit there and rust the floor
Good thing I noticed that before the rust got too bad
Threw the foam away and put normal breathable carpet in problem solved
My 08 Silvy has ruberized coating on the floor under carpet so water dont hurt it
Was the fome cube, for the speakers? (Resonance purpose for sound)
It's to fill a void so it doesn't provide a resonance chamber. Not directly related to the speakers, any sound could resonate in there.
Nice intro! Short and sweet.
These mats on the bottom are the same as they use under a stainless steel sink to prevent vibration ( running water and stuff falling )
excellent work Sandy.....one thing to do the work, entirely another level to Explain it for lay person, I now appreciate Elon's comment "manufacturing is hard".
Gonna bid on that foam block baby!
⬛ random find....
Solving The Money Problem
...perhaps cheaper than a custom part? Hopefully they used a coupon at Joann’s Fabrics...lmao!
Lmao right! Rando foam cubes, kinda love it though
@@Woodlandish For sure. If it does the job, it does the job.
@@SolvingTheMoneyProblem its usefull (cheap, lightweight, easy to install and effective) to fill a void and affect potential resonance frequencies, people are saying their newer model 3's have them as well, so they must serve a purpose
@@Woodlandish they steal them from trampoline parks
At 9:22, is that an extra camera between the grille shutters?🤔
Fabulous. An episode about Edward Deming and Toyota Production System would be awesome. This has been adopted by Silicon Valley under various headings : agile, devops, OODA. Given the amount of high tech hardware and software in a Tesla, this synergy / duality is critical for effective/efficient operation and manufacturing. I know you respect deming. Ben Sullins is a Tesla data science guru and would probably have further deep knowledge for such an episode. Just a thought. Great to see your viewers count soar!
That might be too valuable to show.
Those foam bricks are most likely BASF Basotect, and they are dampening and tame low frequency sounds from subwoofers (aka basetraps).
Thank you for your explanation of what Munro Engineering does as its main business. You are at the heart of a successful capitalist economy. You can’t build a better mousetrap unless you know what others’ mousetraps are doing and how much they cost.
Well done sir!
On my Mercedes SUV I took out the front plastic wheel well liners out and covered them in a layer of aluminum foil constraint layer, a layer of butyl rubber elastomeric layer, and another layer of metal constraint...
Apparently doing it exactly like this creates a sound deadening layer that is as effective as an equal thickness of lead (which is incredibly dense).
I also mounted the plastic on rubber insulators when I put them back on.
It worked so well that I no longer could hear the wheel noise at all...not even above highway speeds with loud mud tires, or even spinning and shooting gravel.
Btw my "metal constraint layers" were just aluminum foil tape, and my rubber is a membrane for sealing basement walls.
It probably added a couple pounds.
Now I've been in all sorts of vehicles, the over built w140s from the 90s (with like 6 inches of dense foam in the floors and double glazed windows in the doors) before MB got bought out by Chrysler and had many of the engineers replaced...new MB, Teslas, new f150s, Austin Martin's, lexus, BMW, Audi, etc...
And not a single one has the nearly zero noise level that my amateur self did.
I also went back and did the rear and now all I can hear is the exhaust.
I also did my doors, but not so much to keep sound out but to keep it in and turn the doors into big speaker boxes to get more mid bass. It sounds amazing. Like nothing on the market.
I really don't understand why manufacturers don't do more of this considering it's so simple and light and brings down loudly audible road and highway noise to utterly inaudible.
I've heard of Audi putting a carpet like material inside the wheel wells to help dampen the frequencies, I was going to try that but like I said the road noise is completely totally gone. Like not there at 100 mph not there.
Would it be possible that a new Model 3 are more similar to the Model Y?
Great video Sandy! I do not mind what you termed a ‘commercial’ as it clearly shows how your company monetizes the outputs for your customers. I am curious if you and the staff provide specific training for design teams, quality assurance experts, college course work, or whatever to keep building good practices across multiple industries. Thanks for all you do. Stay safe!
Sandy, like you presentations, very informative. Wondered given your knowledge and design expertise, how would you design a reusable face mask.
Could you please comment whether the Y shares 70% of parts with the 3? Thank you.
Great question, Shannon! That is one of the many things that we'll be including in our final report. The stickers (red, green, yellow) that you see on many of the parts are our way of identifying whether a part is common (green), slightly modified (yellow), or all new (red) with respect to the Model 3. At this point, it is still far too early for us to give any sort of exact percentage, but once all is said and done, we will know the precise split amount. Thanks for tuning in!
Compiling what has been said so far:
=> Are the same:
2motors + brakes
Electronics (fuze box+battery pack)
The central console (raised only)
2 front seats (by adding unpainted metal raise)
=> Model 3 possible upgrades to increase ur percentage by being the same :
Heat pump (might involve increasing the radiator too the same)
Wireing to pipe, plastic protection, reduce thickness
The rear awsome bucket
Suspension
=>Unknown since teardown unfinished (or since he doest do the small part like the door)
Lights
Front glass panel
Speakers (2 seams to be added to the rear doors)
Middle console (is it the same raise console, r deeper volume space inside)
=> What is known will allways be different
Chassy
All the other glass panels
External mirros
Rears seats
Under the front seats air-vents
@@MunroLive I guess many things have changed in Model 3 since 2017. I think that Mr. Musk mentioned that in just first-year, Tesla made hundreds of changes.
@@Kram668 Vehicle controllers/PDC, or fuse box as you called, are not the same as model 3. There aren't wires in a pipe for the charger, they're busbars.
@@Kram668 brakes
The block of foam is an excellent choice. Even though Tesla's show some sophistication, they aren't ignoring basic tried and true solutions.
9:40 I very much disagree. Cold makes batteries inefficient and charging a cold battery can degrade it very quickly, but hot can cause stuff you really don't want to experience.
I think he was probably talking about the kind of cold and hot that we regularly experience from an environmental perspective, especially in regards to when you would want to use a grill shutter . As far as outdoor air temperatures and Li batteries, we see much more damaging cold temps than hot.
I came for the grandma's meatballs and other snarky remarks metaphors. I love it. 😂
How is the firewall built? Stamped sheet metal?
Yes, stamped steel. Thanks for tuning in!
