I love that you likely spent $40ish dollars on a white noise generator simply for the 5 second gag. It's one of the many reasons I love this channel.
Think he has kids. He probably has 20 already.
@@richardschofield2201 Actually they are all algorithms!
I came here for the cars and left wanting a white noise generator.
Or pro tip (that I do not advocate for) buy online and send back after the short use. Don'tdo that though.
@@richardschofield2201 LOL I have twins. I've gone through 10 of them
Best ad Dynamat could ever get.
it even rimes.
Gillette... Will be pissed haha
Binky first...
The humor on this channel just keeps on getting better and better. Deadpan humor mixed with subtle jokes, and the fact no one has mentioned that you lost your glasses when you were drifting on Hoonigan’s channel
I still can't believe that he was faster than the shifter kart!
Listening to this episode while wearing headphones really shows the sound differences. I really like Dynamat. It is hella expensive, but like you said, you get what you paid for. I put a bunch of this in my 65 MGB and just doing the doors made quite a difference. Great episode, and nice to see another sponsor coming on board. Maybe they will give you a code for us plebs.
Wonder if I can Dynamat my 3D printer 🤔
@@mr_voron if it is encloused and has somewhat flat surfaces, go for it. I did smth similar and it is well worth it!
That sounds like something I should do to my ‘77 Midget, I’m gutting everything in there right now anyway...
The tinny clang from a MGB door is part of the charm. I fool myself that it's the consequence of it being a light weight, sporting component.
You don't need to use this much. In terms of the sheet metal dampener, factory cars (economy cars at least) usually just have the underseal underneath the car, then most of cabin floorpan treated and *then* only a few small rectangular pieces around the boot and one small rectangle on each doorskin.
Plus a fitted insulation pad on both sides of the firewall (with all the holes cut out where the hoses and wiring passes through) and underneath the bonnet.
Then the underlay, be it foam type or cotton felt type, and the carpet does the rest. (With either more cotton felt panels or 3M Thinsulate panels attached to the back of the interior plastic trim panels, but these are usually not full coverage on an economy car either.)
Of course luxury cars are a different story! They have fitted insulation pads even above the headliner, thicker dense polystyrene-like foam covers over the rear wheel arches (& inside the front wheel arches too), acoustic or double glazed glass etc. Even if you heavily sound deaden your economy car with 50kg/100lb of extra insulation, noise will still pour in through the factory glass which will be still be much thinner than on a luxury car, plus vibration will still come through the (usually) rigid mounted subframe unlike the fully isolated subframes on a luxury car.
Of course to obtain a significant difference, it can be useful to use this much or even more of the stuff -- different types not just Dynaliner & Dynapad, but also thicker cotton felt underlay, more insulation on the back of trim panels etc. In a modern car that already has insulation, you need a surprisingly large amount of it to make a significant difference -- the difference might be more pronounced in an older car that originally had almost no insulation at all. Obviously the advantage the OEM has is they can target specific noise sources and be scientific about it with before and after comparisons as to using guesswork. E.g., the "blankets" often found on top of injectors like on the Ford Ecoboost or even on engine timing covers (there's an insulation pad down the timing side of the Alfa Romeo 2.4TD engine) or even the entire engine undertray has an insulation pad on some cars (perfect for absorbing oil!) these days.
Actually, mothers' wombs are very loud for the baby. All that blood and fluids pumping, loud sound of the heart and mother's lungs breathing. It's one of the reasons _shushing_ and white noise works well to calm babies down. Because it mimics the wooshing and loudness of the womb.
That’s kind of a self defeating point, “mimicking the sound of being inside a womb calms babies down”. (Don’t you want calming sounds?)
@@orppranator5230 No my point is that it's LOUD in the womb
But it's consistently loud, few impulse noises. Hence the white noise generator.
@@Lawrence330 exactly
Pretty low on NVH though, I think.
Love the fact that you had only the bass guitar track while taking about noticing sounds that you wouldn't pick up otherwise! Amazing sense of humor!
Because of this video I now know that Dynamat has pre-cut kits for my foxbody, which is currently gutted to the sheet metal and is a lot like being inside a drum. I'm stoked, this really will be a big improvement.
ROFLMAO!!! Gilbert Gottfried between a group of fighter jets and a nuclear bomb!! And the S600 over all. You never fail to bust me up, Matt. Brilliant!! Enjoying the heck out of your build series (both the Jag and the S600) and learning a ton. Thank you!
I too have a knack for ruining my favorite clothes almost immediately with this perpetual lie: "Hm, I should work on that one thing a little bit. Real quick, won't be messy at all..."
Yea, that self argument works with painting too. Ha !
I think this is a universal lie we all tell ourselves!
Pro-tip: turn your good concert T-shirt inside-out before diving into that one quick thing.
This whole channel feels like me without ADHD meds (and with meds too, if I'm honest): Well, I could get the car driving, but I won't do that, and now I'll find justifications for that, and that's one of the many reasons I love this channel.
As a recently medicated ADHDist currently running behind on a two week quick-and-dirty paint job of my daily, this is hauntingly relatable in every single particular.
And yes, it's still two weeks away from completion. Has been for 18 months. Might have turned into a bit of a massively anally-retentive restomod..
I was going to reply with a comment agreeing and mentioning autism being thrown in for good measure, then got distracted and wrote Matt a comment instead. So now he has my comment budget for this video and I have none left for you. Except this I guess, at least I'm on brand(om). Good luck with the meds and the being accepted by society to all of us.
I want someone to explain adhd to me in layman terms, maybe I have it
@@bassam_salim So, let me try. A brain essentially has a "focus budget". Like, doing a thing takes a certain amount of focus, and it is a brains aim to get that whole budget allocated. So, an ADHD brain has a vastly larger focus budget. This may sound good, and in some cases, it is. But if you're - say - a student trying to concentrate on class, that's really hard, as you find yourself doing other things to get that attention budget allocated.
Symptoms include:
- Impulsiveness
- Disorganization
- Problems at prioritizing tasks
- Poor time management skills
- Problems focusing on a task
- Excessive activity or restlessness
- Low frustration tolerance
- Problems following through with and completing tasks
And here's how ADHD meds work: They're actually stimulants. The meds I take are an amphetamine derivate. By giving the brain stimulants like aforementioned amphetamines, or even caffeine, those stimulants take up part of the attention budget, and allow you to focus on more mundane tasks like class.
If you want to find out if you have ADHD, there are a few self-tests online, and if that gives you positive results, you may want to look at coping mechanisms, or, if it's really bad, talk to a therapist/psychiatrist.
Holy cow 200k subs by the end of the year? The algo loves some SuperfastMatt! Congrats on the sponsor Matt, I have a feeling you will get more in the future!
We, his loyal subscribers, hail the Algorithm, and the Algorithm smiles down upon our champion.
Thanks SuperfastMatt for this education in Dynamat installation. You definitely do have a flair for entertaining your audience at heart. AS usual I am impressed at your ability to play TH-cam algorithmic go go ball. I hope your views go up and that is no lie. I click on the thumbs up icon as soon as I see your smile and the JAG appear. This will make a serious video series and needs to be seen and appreciated by anyone that enjoys this humor and know a good time can be had while a professional in many senses of the word make light of a complicated build process.
BRAVO Dyna-SuperfastMatt you managed to do it again.Love the JAG AND hope to see you drive it around soon.
The Sunroof is possibly sealed like my Bentley MKVI with felt around the edge of the moving pannel; the felt works really well and much better than i expected it could.
I still have the engine but i have been trying to get rid of noise anyway.
Thanks for the humor, tutorial, dedication to science, automotive technology, rehabilitation and fun! You go Matt!
Instead of the Dynaliner you could use any HVAC closed cell foam sheet such as Armacell. It is a common industrial product and should be much cheaper. Rated for cold and hot temperatures. For large flat sheets of metal, where you don’t mind a bump. You can glue or tape a strip of 1/4” D shape wood strip on the diagonal or in an X pattern. Then Dynamat over or around it. The wood structure gives it stiffness and you could possibly even save on the Dynamat. For slightly curved panels, I think laying on the wood strip with double sided tape could be done.
I love your content and I look forward to your weekly videos! Thank you so much for showing your mistakes too. So many builders never show those kind of things. The accidentally backward template on the firewall had me busting out laughing because I've done the same thing in the past.
Keep up the great work. All hail the algorithm!
Years ago,I had a class 5 desert car that I drove on the street. Solid-mounted engine and transmission. No insulation. Aluminum interior panels, and a close ratio trans all added up to a seriously deafening experience. Ear plugs were mandatory. An ex girlfriend refused to ride in it. Still, I had some of the most fun in that car that a person can have. Good times!
I just watched a 9 minute advertisement for Dynamat, and I liked it. I think they made the right choice to sponsor this video.
There are only a few channels that I don't skip on forward.... This is one of them.
i love videos like this where you have a problem, you have no idea what you are doing, but you wing it, but do it properly, and it comes out better than imagined
I love your humour, Matt. :) Great timing for the intro.
And I'm all for the logical sponsorship. It's a fine line to skirt, and this sort of sponsorship just makes sense (along with send cut send. )
Also, standing in front of the Dyna_Matt like "hmmmmmm what can I do???" Classic!
Where can we get our "All hail the algorithm" hoodies?
With Dynamat liner..
Merch coming very soon! Maybe a week or two.
@@SuperfastMatt Can't wait! Thanks. (I've edited my 3am local time incoherent comment a little so it.. err... makes sense.)
@@CraigHair But I didn't get to see the original!? What if it was transformative and you just misread it as incoherent with your daytime privelige? #SaveIncoherentComments
I would select Dynamat on the basis of your recommendation. I hope they appreciate just how credible you are and perhaps they will send over a large pile of money to show their appreciation.
considering how much dynamat costs, they basically did send him a pile of money if they covered his material costs.
I once did this the cheap way, getting ice/water shield roofing material remnants and putting it inside the doors of my Saturn. I told myself it made it quieter and improved the audio quality. It definitely made the doors feel better to close.
PS. The rubber roller you use is called a "brayer" for some reason.
Nice, and smart, of Dynamat to sponsor! Helps us to understand the before and after affects of sound proofing; especially obvious when you drummed on the two doors - great comparison. I can't recall how much VW coats their cars with, but I seem to recall they use 35 lbs of sound-deadening spray and stick-on foam - per car. VW sound and paint tech are probably the best in the business; their negatively-charged paint treatments work better than galvanization for corrosion prevention too.
I bet they use 57 styles of adhesive applicators with multiple styles of nozzle tips too.
@@tihspidtherekciltilc5469 Yes, No-doubt; even the robotic seam-sealer nozzles are super thought out. I heard that Tesla's new factories are building cars with one-third the time and effort of current VW plants - due to gigapress and similar tech FYI. You mentioned their focus on steady improvement at Tesla factories in a previous video.
@@EdwardTilley I was throwing shade at VW for using ten types of fasteners to hold the thermostat housing on that's buried in the engine.
Well yes they use it but they use tons of it. I worked for volvo for a few months and the sound deadening tech was always joking about VW that they just spray tons and tons of the stuff on the car instead of using it precisely and just enough increasing the weight unnecessarily and paying more for the Material. He noticed that on a VW factory tour
Oh and VW is definitely not the only manufacturer that uses negatively charged painting techniques.
I know of BMW for sure. But I am pretty sure they use it to waste less paint
**takes notes**
Do it now while it's all apart!
Regarding your beginning segment, it's true, not a lot of people realize how many sounds a vehicle can make, on a motorcycle, the engine's vibration is so loud and overpowering, that if you drive on a highway close to the concrete barriers will scare the hell out of you as you'll actually start hearing the chain, which resembles the sound of throwing a rod
Clicked on this video, well.. superfast. Always great content!
Legitimately happy you got paid for the dynamat since I actually went out and bought some for my project since I didn’t even consider this as a thing!
Early last week I finally found a buzz in my car. Most of the sound made me think it was coming from my passenger door speaker, but it turned out to be my tire pressure gauge vibrating in the thin plastic glovebox.
Glad to see you working on the Jaguar again. I've heard of Dynamat but wasn't aware that it was the Tesla of the sound deadening industry. Always nice to learn something.
These videos are the most informative I've seen in a long time. I have a VW bus I'm trying to get back on the road. I don't plan on making it electric, but your vids on brake lines, steering, rust prevention etc, have really inspired and informed me. Thanks a bunch!
Dynamat made a good decision sponsoring you. I've already seen some of their products that I want to use for my 65 F100.
Always a good day with a new SuperfastMatt video!
When they rate new car purchases for "most trips back to the dealer", the expensive cars always look like garbage.
Another analysis revealed that many new owners go back to dealer in 1-2 months, repeatedly for NVH.
"I can hear a whistling when I am going 85 mph!" The one-percenters complain like crazy.
Well if you dropped that much cash on a vehicle, you'd probably go crazy on that too... Aftermarket vortex generators (IIRC) came out in no time for the A90 Supra because of the wind noise.
I imagine I'd complain a lot more if I had bought a new Mercedes Benz. I purchased a Kia Soul so I'm happy its quieter than my 03 PT Cruiser.
@@darwinskeeper421 to be fair, anything is quieter than a PT cruiser.😀
@@mikealbrecht3990 Darwin, the modified 1979 Malibu wagon, would beg to differ. Mind you, she has had full length tube headers, and a dual exhaust so it shouldn't be surprising that she has always been louder than my PT, or any other daily driver I'm likely to have.
Laser cutting tutorial would be great. How you measure and transfer to an file appropriate for the cutter.
All classic cars that you want to daily need this treatment. I plan on doing this with my 75 Mustang II, my dad did it with his 78 Mustang II and the results are very good.
Dyna-Matt...now, I get it!
THERE'S A SEEEEEEEEEEEAAAAAATTTTT !! I saw it first ! I used sticky foiled butyl rubber for roofs from Home Despot on my hotrod. Not as good as Dynasaur Mat but waaaaay cheaper.
No matter what project(s) you do next, I'll be here to watch, have loved all of your content so far keep it up
It's probably picky to point this out, but a mother's womb is not all quiet. It sounds more like a steel mill or really loud surf. But this is comforting to a baby. That's also why the sound of surf is so restful, FYI. Thanks for another great clip, btw.
I've got a Discovery 4 SDV6, love it. Drove it in to the garage about 6 months after owning it with the window down. I didn't know it sounded like a tractor from the outside!
“Anything not shapes like a teardrop”- so I’m guessing the Dymaxion is super quiet?
*OH THAT JOYUS MOMENT* when your channel has enough subscribers that OTHER PEOPLE pay you to do the stuff you want - instead of you paying to do the stuff you want :-D
6:21 This is why I always buy two pairs of pants when I find pants I like. I always immediately ruin a pair ... usually when performing my favorite skateboarding trick, a superman with a road rash transition.
All progress towards a nicely finished project!
You are an Amazing engineer adding your humor and interesting personality makes this one of the best channels out there ,whatever the content,honestly I wouldn’t mind you literally telling me just about anything ,I would believe you😂😂
one thing i appreciate about this channel is when matt throws around various car enginerding acronyms. He doesn't go in depth\... just like "here, this thing exists"
EVery step counts, (EV .. .you get it ... haha) , so everything you do sharing with us is great to see, still "hungry" to see your progress
Don't care what some peoples say ...
That makes really big differnces. I also have used simple black mats (don't know how you call them in English...) and the difference between a "beng" and a "womp" closing a trunk, hood, door, ... is like converting a cheap car to a luxury car.
Your shows are some of the best, no question. Thank you.
7:57 that’s your dynamat ad right there holy hell
Rubberized undercoating had been my goto for all my shitboxes. Make sure to avoid those with terrible smell. Applies faster than getting access, also super cheap. Gets in all the nooks and crannies like nothing else.
Dynamat is definitely worth it for a car you truly care about
Pro tip, don't run your bare finger down the freshly cut foil to neaten it up :-)
All hail the algorithm!
I'm building an e-bike and that Dynamat would be just the ticket to quieten that horrid chain noise.
Thanks for today's post Matt.
A real engineering focus would be what is the minimum amount of dynamat you need to dampen the NVH. There are studies done on the diminishing gains of full vs partial cover from metal backed butyl rubber sound deading. For doors I think it was 30% cover on the resonant center of the door skin as well as the inner door frame
Yeah, economy-type cars (so a Renault Megane or a VW Passat) usually only come with one rectangular panel of deadener applied somewhere near the middle of the doorskin. It's enough to remove the resonance of the door panel and get rid of the hollow clang sound that makes the car sound cheap when the doors close. There are usually some insulation pads (cottonfelt or 3M Thinsulate) stuck to the back of the interior plastic door panels too, but again usually not full coverage.
If it was a Bentley where the goal is to try to block as much as noise as possible coming through the door including double glazing (as well as trying to block noise as possible everywhere else including the roof), I guess the approach to insulating the door would be quite different?
I think it is important to use a variety of different types of insulation. Modern cars usually have fitted insulation pads on both sides of the firewall and then the carpet underlay and so on. Luxury cars often have thick polystrene blocks over the front and rear wheel arches (in addition to the carpet-type insulation on the wheel arch liner itself, sheetmetal deadener directly on the cabin side of the wheel arches, carpet underlay insulation on top of that on the inside of the wheel arches -- I even saw this on the *front* wheelarches of a Ford Focus which is inside the engine bay which seems crazy but front wheelarch>engine bay>cabin must be a significant noise path, big foam pieces to remove cavity resonances from the rear quarter panel area etc).
Good thing they said yes to sponsoring you!
Thanks for the tips Matt
Loving the algorithm. All hail Matt!
I really suggest getting into aerodynamics of the car: there are many things you can do with cars, especially old ones. I can recomend Julian Edgar's books on the topic.
Maybe Matt should follow in the footsteps of Malcolm Sayer (Jaguar's head of aero who developed the D-Type in the early 1950s). He taped wool tufts into the car and adjusted the shape to get smoother airflow.
@@johnmckay1423 Wool is just one of many test methods BUT it shows only where flow detaches from car. There are much more you can measure to get information about aerodynamic characteristics of your car.
Really LOVE your deadpan humor :D
Dynamat /Dynapad are the best products by far. I also use expanding foam for hollow sections and mass loaded vinyl / closed cell foam if I cannot afford Dynapad. Every car I own I fully sound proof the trunk, hood and under the rear seat..takes away boomy road noise and a lot of exhaust/mechanical/suspension noise.
just got here and 66 likes already... you rockin, dude. even if you dont play the telecaster
It would be intresting to know the cost of the electronics, drivetrain and all the things to make it electric.
When my 68 Cougar was T-boned, and repaired, the did not replace the sound deadening material in the door. It was ver noisy in the interior after the repair.
So glad you talk about sound perspective. Man so true on a bike. If it were not for the ICE vehicles we could hear the EV's
I gotta figure out where to put some Dynamat in my 1912 Model T....could def use some good NVH
The collector on my long tube headers blew out yesterday... my 383 idles louder than your car at highway speeds for sure.
Love your work!
Love the drum comparo
You should do all your videos from in the car. It's a good spot ❤
All hail the algorithm.
Enjoying this build, looking forward to more updates, keep them coming 👍.
Great content Dyna-Superfast-Matt
Get custom "musicians" ear plugs. They reduce the volume of everything but let through the frequencies. They're fantastic
As an ev owner, YEAH... Even a plastic water bottle on the door bin is annoying.
Awesome work!!!
That sticky Dynamite stuff can sure make a mess, it used to give me a headache and piss me off all the time lol. And then when I had to go remove a piece of it lol took forever!
@SuperfastMatt, I need to know for my project, what paint did you use for your floor? Is it a special paint? Or just paint?
SPI Epoxy Primer. awesome stuff, really tough. it's made to go on bare metal and you can put body filler over it, so it's great to put down on anything you might paint later. or anything you need a tough coat on, like the floor.
That Jag is 50 miles of lacquer paint... oof.. the buff out is going to be crazy cool!
I don't know man, I've had a electric Kia Niro and the ONLY noise I hear is the fake noise it makes under 15 miles an hour to be audible to pedestrians. When I turn that off... Nothing.
old age does help :) and it is also half of the point Matt made. using sound deadening works, especially if it is installed, like on new cars.
So you're saying if you want to hit a pedestrian you just have to be going faster than 15mph? Interesting. It would probably look strange with a bullbar though right? ;D
I can hear the clicking of the high voltage contactors and relays in my volvo xc40 p8, also a slight motor whine during acceleration.
I like the old outro where you talk about impressing the algorithm 🤣
Apparently the algorithm has been hailed enough that he deemed it unnecessary.
Who's that Al Gorithm person anyway?
@@TestTest-eb8jr clinton had rhythm, gore invented the internet
@@baldrehdead 😁
Really enjoying your channel especially the Jag. I've got a Riley RMA but I wish it was a Jag . Plus you're funny, you remind me of a certain comedian from the 1950s but daren't say who in case you find it an insult.
Matt, have you considered transplanting an entire Bose audio system with ANC from a wreck? I think the hardware would probably be straightforward enough. The software? I don't know. The system will be tuned to the donor vehicle and very likely has routines for things I cannot even imagine. But, it might be worth investigating. ;-)
I kept coming back here and had to just accept that I needed to subscribe at this point
Seems a pleasure how somewhat easy it is to get away with sound deadening that car. Anyway. Are you planning on installing any aftermarket stereo in it?
I’ll probably put some speakers and a Bluetooth receiver hidden somehwere
Ahh the Algoritm have provided GOOD content, blessed be the Algoritm.
What would you guess for the weight of all the dynomat?
About 85 pounds (40kg) for the whole car. They sell a lightweight version called SuperLite that is 30% lighter. If you're worried about weight, you can just do the middle of the big panels. it won't be as good but it'll be a lot better than nothing.
awesome as always!
Great info!
i've been wanting to go in the opposite direction of a normal person with my FR-S and add a bunch of MLV and CLD. i'm surprised to hear that dynamat is that much better, and i wonder what it is that makes that so? (it's all butyl rubber with foil on one side, no?
Reminds me of a comment i saw about trying to make your computer quieter. You end up doing shit like choosing quieter bearings for hard drives or something like that.
Are you from the bay area? I'm in SF bay, also work for Tesla. Super cool build! I'd love to check it out in person, maybe lend a hand? Nah probably dont have time. Anyway, keep going!
Back seat is a good spot for talking to camera
My favourite channel!
7:28 Might I enquire? How many layers of arm skin did you deposit on those razor-sharp door panels with the backing removal?
gotta be honest, with a completely flat floor, which almost no car ever has, I'd be tempted to skip carpet and go with something ridiculous, like a hardwood floor.
Shouts from the mountaintops became a whisper ...
“salvete algorithmus” ...
We had a code for interior design NDH, you could spend a fortune on a sound deadening interior, leather and real wood but fail due to not having NDHs. Someone climbs into a showroom car, and after gripping the wheel and staining moodily off into the distance, check s for NICE DRINKS HOLDERS….
Nice... I looked at dynamat for mine, ended up going with another brand that's a little cheaper. Time will tell if I regret it. Mind you, I'm fitting one of those dreadful old-fashioned internal combustion engines, so it probably won't make a lot of difference anyway. My car isn't exactly a Bentley :D
He gave that Jag an ultimatum, "Quiet down or else I'll Dynamat you!"
God I love sound deadening material... Wish I had watched this video before I bought and applied Killmat to my project, but the results are still addicting. My wife had to keep me from Killmatting EVERYTHING in my vicinity...
Does dropping comments on old videos as I marathon them help out your Al Gore Rhythm? I hope so
actually, you can use chademo and ccs adapter and i guess you will gonnna be golden. Just got my own tesla 3 pack finally.
