This is the single most important experiment in the history of turbocharged engines. I was hoping someone did this experiment one day, but this surpassed my expectations. You guys are so funny, first video I watched from your channel and I loved it. Noice VL too!
The 3inch stainless 90⁰ was pretty mint. But I had my money on the saxophone I really wanted it to sound go so I could go get one and chop it up it looks kang🤴
I’m a trumpet player and also a scientist. I didn’t think I’d see a couple car mechanics use the scientific method to understand how harmonics form in an open tube based purely on an instinctive but deductive approach. And the source of the vibration is a turbo surge. Pretty fascinating. You guys have good scientific minds. RIP the saxophone. It’s brass btw
This is the video the internet never knew it needed. For science and for glory! Ive youtubed this topic many times, and there has been nothing until this video that goes through the different pipes, sizes and materials. Kang content, and some absolute kang doses! 👌🏽 If I had to pick, it would definitely be the 4” stainless long 90 for sure or the copper 3” for backup. 🤤👌🏽 The 1.5m and 3m stainless pipes were pretty sick as well, just very impossible to street about with. 🤣 Stay Kang boys! I’ll see ya when I’m picking up the 32 Gtr. 🤙🏽
I agree. The 4 inch 90 was dope. But honestly the 3 inch straight alum in my opinion is dang good too. Id have to keep extra pipes in the trunk. Change em while gassing up
Yo dude i think we are the minority here, I like the stretched out initial sound, and the longer flutters. I liked the 4" 90 degree titanium short boi the most. But the best way is to actually go lower boost to achieve it or so I've heard.
OK I’LL CLICK THE DAMN ADVERTISEMENT! I actually enjoyed this video and subscribed, too! Also I love that you’re actually doing baby burnouts to truly test each one under full power load! Much love from Texas!
YES! I've talked many times about REALLY wanting to do this test! Nice work! Having an anti-surge inlet on the turbo fucks it up too. I've literally JB welded one of my cars anti-surge up for this reason lol. I prefer the higher pitched ones, but I can't potentially give up airflow just for the cooler sounds, tho it's tempting. Love it
This was amazing! Always wanted to see what changes the flutter sounds. You guys did it! Thanks guys for putting so much effort into making this video, Love it😸
Turbo flutter is not when your turbo spins backwards but it can be bad for your turbo because its releasing air back into the blades and causing them to vibrate hence the flutter sound my first turbo car i blew the turbo on cuz i thought it sounded cool 👍
@@eshbanvelez5212the air pressure slamming into the throttle plate and the “flutter” your hearing is the pressure being “cut” by the compressor blades… same thing happens to your voice when you talk into a fan… It’s impossible for the turbo to spin backwards, the air pressure is being forced through the compressor backwards but the compressor never changes direction 🤣
3,5" 90° Stainless is my favorite, but you can really see what the material, diameter and pipe length do and how you could use it to dail in the sound of your turbo flutter, which I love.
so I think if 4" 90° Stainless would have been a little bit longer of a pipe it could have taken the overall crown, but due to the pipe not being long enough you got the STUU but not the TUTUTUTU
Amazing video!, you should also do a video of different type of filters! So the sound difference with cotton, mesh, no filter, foam filters and muschroom filters
Honest to god man Jason is the funniest man alive 😂 I’ve made it too 1:50 and I’ve had to pause and come to the comments, genuinely crying with laughter 😂🤣😂🤣 keep it up boys top work 🏆
Nice video guys sure has got me thinking about my intake when i get to mounting my new turbo i honestly don't care about the performance but the sound ohh yeah
amazing content, I love the summary, but you should really time the length of each dose and put it in a table, then graph the piping pressures with a map sensor to see how each pipe affects the graph. then you can publish a scientific paper
The pressure wave and subsequent sound is directly attributed to the sine wave produced. The length of tube affects the pressure wave as it bounces along the tube hence the sound. Zututututututututu kang!
22:08 for back-to-back comparison. I like the higher pitched ones with the drawn out first note, but IRL I would choose whatever was least restrictive while still giving me an ACTUAL dose sound instead of just a sigh. So probably one of the 3.5's or longer 4" stuff.
brah. this is the information right here. so many noobs thinking the BOV is where its at.. NO BOV. Dose it up! in the olden days we would wedge a coke bottle lid in the BOV pipe to make the Dose.
Try to make one that is has the same form/profile as a horn, either the round trumpet ones, or a square one like the end of those "snail horns". Interesting vid, had no idea that it would make this much of a sound difference. 10/10
The bend angles, and lengths, will affect the sound waves either muting them or reinforcing/enhancing/amplifying them. Similar to wiring speakers out of phase.
Part 2 is here!!

@@nathanrowbottom3463 Haha my favorite is the 3" 90 bend @10:20
Respect
what garrett you got?
I can’t believe I just watched a 25 min long video of just turbo surge 😂 and I didn’t lose interest for one second
only car vid ive watched fully in weeks XD
I came for the turbo sounds, stayed for the pure Australian car shenanigans.
Flutter is different from compressor surge.
Not once in history has that been done and even I did it 😂
@@MrShakotan Compressor surge causes the flutter sound my guy 🤦
This is the single most important experiment in the history of turbocharged engines. I was hoping someone did this experiment one day, but this surpassed my expectations.
You guys are so funny, first video I watched from your channel and I loved it. Noice VL too!
Welcome mate ✌️😊
exactly! i was wondering how these things impacts the airflow/sound. good stuff
The 3inch stainless 90⁰ was pretty mint. But I had my money on the saxophone I really wanted it to sound go so I could go get one and chop it up it looks kang🤴
Awesome 😎 science 🧪 🥼. Check my channel if u want to hear 👂 Dose flutter from my recent r34 Gtr single turbski build. Melbourne big D Lad here too 🍆💪😎
Wot about a tin whistle kinda deal with the long pipe
Use a velocity stack
Best sound in my opinion !!!
This was both hilarious and pretty educational at the same time 😂
Been loving the content recently, keep it up bois
Would be interesting to see what multiple bends does
You mean what multiple bends dose
Yes and pie cut bends
@@felix.f8747 pie cut loop
How about an expansion chamber like a (decent) 2 stroke?
Helter-skelter stylee

Stay Kang boys! I’ll see ya when I’m picking up the 32 Gtr. 🤙🏽
This is the information I needed so many years ago when I first got my VL. This made the 16 year old version of me inside my brain very happy
I agree. The 4 inch 90 was dope. But honestly the 3 inch straight alum in my opinion is dang good too. Id have to keep extra pipes in the trunk. Change em while gassing up
I love it when the car lurches forward after every pull. Insane flutter.
22:54 the camera captures the pressure shock in the air
Either the short 4" titanium 90 bend, or 90 bend carbon for me. Personally I like that more drawn out "sigh" sound.
Yo dude i think we are the minority here, I like the stretched out initial sound, and the longer flutters. I liked the 4" 90 degree titanium short boi the most. But the best way is to actually go lower boost to achieve it or so I've heard.
Based
Me too mate
My favorite was the 3” Copper. Makes me wonder how it would’ve sounded with a 3” Copper with a 90 bend.
OK I’LL CLICK THE DAMN ADVERTISEMENT! I actually enjoyed this video and subscribed, too! Also I love that you’re actually doing baby burnouts to truly test each one under full power load! Much love from Texas!
YES! I've talked many times about REALLY wanting to do this test! Nice work!
Having an anti-surge inlet on the turbo fucks it up too. I've literally JB welded one of my cars anti-surge up for this reason lol.
I prefer the higher pitched ones, but I can't potentially give up airflow just for the cooler sounds, tho it's tempting. Love it
did the JB weld idea end up working ?
@@Jay_emm not used it yet but yes it works
I really like the high pitched ones - The copper pipe gave a nice combo of duration and pitch too
Wow, I would never have thought it’d make so much difference
PROPER DOSING SCIENCE thanks mates from Gresham Oregon USA i will be watching more vids for more FLUTTAH
This was amazing! Always wanted to see what changes the flutter sounds. You guys did it! Thanks guys for putting so much effort into making this video, Love it😸
That sound it made when the intake coupling popped off was amazing
I'd love to see a very narrow dose pipe for the high pitch dose but make it long like the big D for that long dose. That'd sound KANG!
Love the science boys 👌🏻👌🏻 the 3” staino 90 was noice. I love that VL
Now its got me thinking of dose pipes with different diaphragms and baffles
Ahhhhh the sounds of melbourne. Hahah I remember going to school and hearing go dosing from a few hundred metres away ahahah love your work fellas!
Things I didn't know I wanted to know until now thank you....
I love UA-cam
10:20 is the best one imo.
I don’t think this has ever been tested but I love this now we know what one is best for each setup all cars will vary
The 142 dislikes are the people who still believe flutter is your turbo spinning backwards lmao
Could you explain then what it is? Cause I got my first turbo car last year and this was always my perception/what I've always heard, TIA
Wait you can see the dislikes?

Absolutely a fantastic idea and I'm so glad you guys took the time to make this video. The ending compilation is the icing on the cake
That saxophone one was too funny
Turbo flutter was my favorite sound in group C and group B 🔊🔊
Hilarious!
Enjoyed the energy and enthusiasm. Had me smiling for the whole time
Thanks!

This is the good content glad you advanced it, not buying merch whatsoever but good ole classic car UA-cam style content is amazing
Keep up the VL content, loving it!!
Nice Sound 💯😎👍top Work
this has to be one of the best videos ever produced
Never heard of your channel until now and I am a proud new subscriber. Fahkin amazin
a guy around the corner from my house owns a VL and it sounds so good.
Sik VL aye. Never owned one but driven a couple in the 90's, 15psi the most and it was still pretty good, cant imagine 26!
Original, educational, hilarious, and done in a VL. Pure content no filler. Video of the week for me. Thanks man.
Amazing video!, you should also do a video of different type of filters!
So the sound difference with cotton, mesh, no filter, foam filters and muschroom filters
How have I never seen a video comparing this before, super cool.
That 3” stainless long boy and that bend was my favourite
Honest to god man Jason is the funniest man alive 😂 I’ve made it too 1:50 and I’ve had to pause and come to the comments, genuinely crying with laughter 😂🤣😂🤣 keep it up boys top work 🏆
Me just watching the skyline parked. 🤤
All kinds of dose pipe ideas floating in my head now.. LOL.. I wanna see a 3.5 down to 3 aluminum straight...
4” stainless 90 is the chef’s kiss🤌🏽
Needs a velocity stack and it will sound even louder 😁
Bruh who else clicked the ad 💀
Fluflufluflufluflu 😂
Me
I finally gave in haha. Hopefully I’ll stop seeing it now.
Stututututu
Exactly
What about doses for diesels? and how do I make a specific type of dose sound in a diesel. (TD42 nissan engine)
Nice video guys sure has got me thinking about my intake when i get to mounting my new turbo i honestly don't care about the performance but the sound ohh yeah
AWH THIS IS GREAT! THOSE TOO TOO SOUNDS! THANKS FOR MAKING THIS GUYS, MADE MY DAY!
amazing content, I love the summary, but you should really time the length of each dose and put it in a table, then graph the piping pressures with a map sensor to see how each pipe affects the graph. then you can publish a scientific paper
*_This is the ultimate test. Like the ones where they try on multiple exhausts to see which one sounds the best, but this time it's a turbo!_* 🔥
Wtf you smokin on 😂😂
This is the most ridiculous yet entertaining automobile related content I've seen in minutes 🤣
First two minutes of seeing this absolute chad and im subscribed
The 4in copper was awesome
how about some love for that car handling all that boost standing on the brakes torture ? what a machine!
this was by far the best dose video ive seen.
Amazing content. We need a KW to HP conversion sometimes! 🤣 American fan here!
15:50 THAT ONES MY FAVORITE, I LOVE WHEN IT HAS A LONG STUUUUUUUUUTUTUTUTU
What is that the 4inch 90 degree stainless long edition?
Haha funny stuff boys.
15:51 reminded me of my diesel mondeo st and for that i call it a winner!!! And the 3 inch titanium
At least the vl is getting used, gorgeous car.
I love the low little chuckle she's got goin' on. tututututututututu
Many vehicles have found their way into Junkyards due to videos like this!.
Greatest video on the internet.
That trumpet looks sick on the car don’t know what is sounded like though
3 Inch straight sounded the best in my opinion, i think i know what the next Upgrade in my S15 will be
4” 90 degree stainless was my favourite personally
One of the best videos I've ever watched 😂😅😍😍
The pressure wave and subsequent sound is directly attributed to the sine wave produced. The length of tube affects the pressure wave as it bounces along the tube hence the sound. Zututututututututu kang!
This is good quality UA-cam’s
Haha actually watched all of this! Cheers for the vid legends.
Wife just constantly looking at me funny.....
night shift providing the good videos tonight.
the trumpet 💀🤣🤣🤣 nice one guys
Sweet science project professor

Well done boyz was fun to watch. And learn bit of science
Copper surprised me, pretty decent!
In the old days fellas would do a bit of copper in the exhaust for sound...
3" stainless, love the whiieeee
brah. this is the information right here. so many noobs thinking the BOV is where its at.. NO BOV. Dose it up! in the olden days we would wedge a coke bottle lid in the BOV pipe to make the Dose.
IM IN LOVE WITH THISSSSS
Dope video.. keep doing stuff like this.. helps the customer and you find what your trying to achieve so your both happy
I reckon the copper and titanium sounded spicy 🔥
Fell of me chair laughing at timmy the trumpet
3inch stainless was my favourite
Surely someone can make a song out all these sounds 😁
And I still love you your sense of humor I'm I don't really have one but I bet it's funny
thx for the dose class boys, love that sound!
Try to make one that is has the same form/profile as a horn, either the round trumpet ones, or a square one like the end of those "snail horns".

The Australians have invented the didgeri-tsutsutsu 😂
Yea the didgeridoostustupstupid stuuuuppiiddd
I really really don't think I can't hold back from intentionally forgetting the blowoff valve for those sweet sweet noises
This was a good watch ya funny buggers they all sound good I think to be honest and yeah the saxophone is brass
