Best sounding one I've heard so far🤤
Appreciate it🤙🏼
Its amazing on the ears
YES THIS IS THE ONE!
YESSSSS
Crazy how it's sounds similar to the mk6 R versions. Love that sound. I call it motorboating flutter 😂
Okay, just looked at the title, haven’t watched.
Flutter is caused by a lack of a BOV/DV, or the BOV/DV not being able to blow off all the excess boost pressure. So the only reason a BOV would seem to cause flutter is if it’s not doing it’s job adequately.
Honestly i want to try it out, but i got cold feet, don't wanna break anything in the long run
its will break 100% no wonder EU gti has better reability then UK or US u know why? EU is forbid to tune engine so alot ppl don't touch like 85% i guess its funny cuz when u want to buy gti in UK or US there always touched "ecu" tune so compared EU almost no one touch that also vitale...
Cant speak for all of Europe but here in the Netherlands ecu tuning is done a lot ..but mostly by specialist companies
Dude said it’s stock but it’s fbo😂
Lol feels stock compared to the other cars i guess
Stock internals
He said it's a stage 2 tune. Not stock.
Basically looking for "this" vid for a while and by far the easiest to setup and fix up again IMO versus others... great content and info gained a download and a SUB👍🏼
Thankyou! This is what we love to hear, we are doing our best to bring our viewers the best content we can! we appreciate it!
summer 2022 is going to be a banger
new BOV that can't open because the vacuum line is disconnected. Why buy & install a BOV if its not going to be used?
IHI is20 turbo: [*glass thrust bearing*]
CTS turbo: haha turbo go stututu
Yeah we should get the is38 turbo lolol
OMG You're going to blow it up! Holy shit!
Under every video of turbo flutter, there will undoubtedly be a bunch of wise folks spreading the word about what turbo surge is asif they’re the first to ever hold this knowledge … we know what it is, we know it’s not ideal - but it sounds cool 😂
so basically we have to remove the vacuum line from the blow off valve?
Yup! Thats about it
@@SvGTAPES isn’t that bad for the turbo????
Volkswagen does not have blow off valve
@@_shtboxgarage generally this is bad for your turbo. this flutter comes from air travelling back the wrong way thru the turbine rather than blowing off or being recirculated
@@yobi.variantits called air reversal and there is no documented evidence of it damaging turbo, turbo is going too fast for 20psi to do any damage. I had no bov on a T25 for 10 years no play on turbo..
If I had that I’d be doing it everywhere 😂
Sounds like the 3 Stooges doing there classic laugh 😂 🤣
I like it mine's the same love it🤙
Hellll yeah!🤣 thats awesome!
That’s noise is the vacuum that you’re clueless about. Lol 😂🎉
Got that spy vs spy laugh
Lolol
If the turbo make 60.000 km instead 100.000km with this sound... Fuck the turbo!! This sound is amazing!! ✌🏻😂
Hellll yeah mannn
I like the BOV sound but the reason I'd rather not use a BOV is because it's less efficient than the DV. Unless you have one of those 500+ HP setups I feel like it's not worth it to install the BOV.
This is very true! A DV is much more efficient
@@SvGTAPES so if i get a bov will i lose power?
@@SIXvw no a bov will not cause a loss of power
@@SvGTAPES thanks for the quick response man i appreciate it🙏
@@SIXvw yesssir always🤝
Sounds like a mean squirrel scolding me from the trees.
That shit sounds so cool hahahahah
Yessss nate
Oh god that sound soooo good, pls let me know where I can buy all the things ❤❤
This will kill off your turbo quick.... that noise is charged air hitting the turbine of your turbo and will cause excess wear on the shaft
if your want a BOV sound buy a RECURCULATING BOV that dumpsn 50% to atmos and recurculates 50%, this will give you the noise, not damage your turbo and will not give you a check engine light
Yep. Absolutely correct!!
Wrong…
ua-cam.com/video/2QaajARc_CQ/v-deo.html
Nah it'll be fine. Aussies been doing this for donkeys years 🤷🏿♂️
It's not that serious 😬
There is a difference between open throttle compressor surge and closed throttle compressor surge as long as it’s not fluttering when the throttle is open, it will be completely fine on your turbo as the turbine is no longer under pressure and is freely spinning.
…we know.
Wow really you guys are just pulling the damn boost controllers vacuum source off your vvt control causing your Westgate to be stuck closed 😂 this equals a fried turbo
I could do that ALL DAY LONG MAN
Rightttt it’s music to the ears lol
what can i do to get this sound all the time without damaging anything
Can I do this on my 1.4 TSI? And it's hurt the turbo?
We have the cts bov that is what is making the noise
This is definitely a video of what not to do with your turbo vehicle especially a volkswagen... That turbo is not gonna last at all...
What BOV and Intake you using? That’s the noise I’m tryna get my turbo to sound.
Cts
Perfect✨
🤝🤝
Hello, I've been trying to get this sound on my golf 6 1.4 which is tune stage 2 with 33kg of torque... I have the intake just as you, my turbo goes 1.5 bar of pressure.. so i always thought i should put a hard spring inside of the stock bov, but i think that this has nothing to do with the bov.. whats that cable you unplugged?
He said he doesn’t know, don’t you pay attention?
@@johnconnor8179 No, i was watching Terminator sorry
It's the vacuum line for the diverter valve
is this the bov or the diverter valve one
This id the bov from cts
Nope, my bank account dies in 10 hours… going to buy one of these right away.
Ok you convinced me im buying it right now
Hahaha awesome man!
That sound incredibly wet but 25 pounds of boost and it flutters, aren't u scared for ur turbo?
Can this also be done on the same year golf r?
Does this hurt the turbo?
It shouldn’t be hurting the turbo directly because it is the valve making the flutter not the turbo, but it defiantly isn’t good for the turbo. Like we said it did throw a code eventually, so we wouldnt recommend driving around usually with it like this
Yes it’s turbo surge, by pulling the vacuum line off the air has no where to escape so it hits the turbo blades causing surge
Yes it does
certain turbos can take lots of surge, and others cant. Turbos like Holset's, Garrett GT37R's, GT40R's, or larger with beefy thrust bearings can take a lot of surge out of the box. Turbos such as TD05/TD06's, Borg Warner S200/S300/S400's, K24/K26's, Garrett T3/T4's etc can take surge as well as long as they have an upgraded thrust bearing. That's the one part of the turbo under stress when surging, the thrust bearing. On a turbo with a not enough thrust bearing journal area, the thrust bearing wears out quickly (because it is overloaded with thrust load and the oil film is squeezed away) and then you get loads of in and out shaft play. Then one day the compressor wheel tears itself apart by hitting the compressor housing.
And another thing, turbo compressor nuts are threaded in reverse from the turbos direction of rotation, so they don't back off, they will only get tighter. Basically any OEM turbo is not designed to take the extreme thrust load from surging. Small frame steel ball bearing turbos will develop excessive shaft play from surge as well, ceramic ball bearing ones are generally okay.
Bottom line is most properly built aftermarket turbos with 360 degree thrust bearings, or just plain ceramic ball bearings can take the load of compressor surge. If you surge your OEM turbo it will probably last a good 6 months to a year of daily driving, less if you're running more than stock boost.
Let’s educate people on this issue. Yes it’s a surge and surges can be damaging to the turbo bearings. This surge however, is not damaging to the turbo and I’ll explain why. The two types of surge is power on surge and power off surge. Power off surge is when the air cannot escape the system and hits the turbo blades causing the flutter. Power on surge is when the turbo is making too much boost for the system and it flutters while you’re on the power. The dangers in power on surge is the fact that you’re having force from both directions push on the blades and that can damage the shaft of the turbo and bearings pretty easily. Power off surge isn’t bad for the turbo because all it’s doing is causing the blades to stall and isn’t anymore pressure than the force it gets from just normal operations. The dangers caused by surges can and do expand away from just the turbo in a lot of cars. Since every Audi and Volkswagen currently made uses a diverted, which is designed to dump the extra pressure into the intake manifold, it can be damaging in other ways. When the diverter doesn’t work properly the car will be expecting all of the extra air to come in and thus keep the mixture rich for the expected air. Since the car is keeping the mixture rich you tend to have misfires and this can cause a lot of issues. From my experience of my diverter dying on me, my car started misfiring and I pulled over to try to not damage it. Unfortunately the constant rich mixture caused damage before my car misfired and threw a code and this caused my knock sensor to die. I was driving a 2008 Passat with the tfsi engine and replacing that sensor made me lose part of my sanity. Having a rich mixture can cause detonation after a while as well and this can total your engine. As you can see your turbo isn’t being damaged from a power off surge but in cars tuned or programmed for diverters this can be very dangerous. Luckily this man has a gti tuned for a blowoff valve so he doesn’t have many risk associated with this trick. I’d say the check engine light is just from messing with the vacuum system and not the flutter. There’s ways to stop the operation of diverters and blowoff valves to get this flutter but you’ll have to retune your car for it and it’ll make your car slower compared to just keeping the diverter. I’m pretty big into Audi and Vw and this seems to be a common misunderstanding when it comes to the turbo system. Personally if I wanted flutter it would be on a fully hand built engine and not a factory tsi with some bolt-ons.
Fire!!!
Nice
Yessir
So I did this on my mk7 GLI for fun and literally nothing changed?
Weird, do you have the cts bov?
@@SvGTAPES whoops haha no it’s oem
@@deffwishh ahhhh yeah
Get a turbosmart plumb back. Sounds the same and plugs right up no running vacuum lines..
Where can I buy save sounds?
If you care about performance, don't do this. You will have to rebuild boost everytime you go back on the throttle. On the other hand anyone who tells you your turbo will blow has no clue what they're talking about
Can you share the part number for the bov please?
Anyone know how this would sound/perform with the stock recirculator? Or would there be no noise as its still all being recirculated?
Can you link where and which blow off valve you used?
It is the cts bov yeah we will try to link it
Sounds awesome!! Would i be able to do the same on wrx 1999 model?
You will ruin ur turbo this way so good choice
what is the name of blow-off valve ???
nice way to shorten the lifespan of your turbo haha 😆
What blow off valve and intake is that ??
Can this work on stock mk6 golf 1.6 diesel ?
We do not recommend trying on a motor that isnt the one in the video. but if you wanna go for it, it wouldn’t hurt it too bad to try
So would running a diverter spacer be safer ? Still have cool pssshhh noises tho
We havent heard of that to be honest, so we cant speak on that too much. Also we had a blowoff valve in the gti, so you will probably need a blowoff valve but it couldn’t hurt to try a spacer to see if it will give you any noise if it isnt too expensive
ECS diverter valve spacer and it’s 50 bucks makes crazy turbo noises
@@noahhhjenkins8137 it’s great and all but be aware of more oil consumption It’ll spray oil in the under part of the engine ,I’m definitely looking forward to Upgrading to a Ko4 T I’m sure the Spacer will sound even louder But with all VW’s Timing chain replacement comes first for Engine longevity
@@BarnsB_23 I have it installed in my B8 A4 and I the cad was already consuming some oil but I think I noticed that indeed is consuming a little more oil, but why is that ? 😅
@@samwh4775 I highly recommend you keep the stock Diverter valve Bolts that came with the car take the Diverter valve spacer off for long distance travel Because the Tsi motor will spray oil everywhere causing oil consumption You’re better off Upgrading your Exhaust,Air intake,Ignition coils, and a soild tune .up The boost just a tad bit on the K03 turbo and Run a “HKS BOV” the Diverter spacer is Only fun temporarily until you can Truly up the Performance on Your Tsi motor
Is it 1.8l ? Like my polo 2015 gti ? Tsi ea888?
😅 my guy will kill that poor snail 🐌🐌 real quick
Fuck ya turbo flutter!
That sounds like it's mostly turbo flutter and not BOV sound. Notice the BOV you only hear on the high revs which means the stutututu is turbo flutter and that's unfortunately bad for your turbo.
It is definetly bad for your turbo in the long run but judt unplugging it for fun isnt too bad but we do not recommend lol
@@SvGTAPES true, true. Sad that BOV's cant replicate such a flutter sound hehe.
@@noiztrauma fr buts thats the give and the take of flutter lolol
its not bad for your turbo, 20psi of air cant hurt a turbo spinning at 200,000rpm
I ran no BOV on a T25G for 10+ years turbo is fine. Flutter away!
Absolute worse case is its ever so slightly going to slow turbo trying to spin back up to generate new boost but we are talking under 1% difference here..
Can i put this on my mk7 tsi 1.4 ? 2016
How does someone make this sound without just unplugging lines? Is there a correct method to achieving this sound without hurting the car long term?
Yes buy a hybrid valve and set the spring properly with bov port closed for tuning then open it back up after tuning boost levels you will get stu stu stu with pshhht and best part you can tune it to either or both mine is full dv mode and I get 5 to 7 stu stu stu but I'm also fully biult around low 500whp last dyno 527 a year ago 542
Can you do this on mk8?
so... you pull your engine vacuum line off. Maybe it's there for a reason?
Oh yeah its there for a reason lol
@@SvGTAPES yes, I wasn't trying to be sarcastic, I'm an engineer, and I build, so I was just confused. I'm also very literal, so, apologies if it came off wrong. :)
@@vanquish_engineering oh cool! Yeah it did but thats okay! Thats sweet yeah we just disconnect that for nice noises it is needed
What BOV did you use ?
Scirocco 1.4 also can do like this bro ?
Yeah if it has a turbo motor it can have a bov which would make the noise if done right yes
@@SvGTAPES name for BoV bro ?
@@farhanzambri204 cts bov!
Bro do u know how to do it in the bmw x1?? 2021? Plis
Nah sorry man
I can do that i'm My GTI mk5 automatic? If i isntall bov?
Yeah pretty sure you would be able to!
I have a 2.0 tfsi you think my turbo will be damaged over time if i add an aftermarket BOV or affect the engine at all
a bov shouldn’t hurt the turbo from all the research i’ve done recently. im confused though because i thought bovs don’t flutter but in this vid they do
What’s the name of it
It's not working.......
what kind of blow off value
A cts blow off valve!
How do make a Mercedes w204 flutter like this
Does this work for mk5 polo’s???? 2017
If it is the same motor that is in the mk7 gti which i think it is, it should work
I have this same setup and doesnt sound like this something is wrong dude
How do I do it to my mk6 2010
Going to have to see if cts offers a blow off valve for your car first!
The bov is not opening soon enough
Yeah
Would you say its safe to drive around like this everyday? I'm guessing not but worth an ask anyway
Nah we wouldnt recommend having this done everyday
@@SvGTAPES It's just something to do when not moving then?
How did it cost in total for the bov and intake?
Roughly $500-600 at the time, we get the GTI parts from urotuning.com
Where can I buy this blow up valve , I've got a Volkswagen golf tsi would it work on it
Unplug the diverter valve and it will work, thank me later
What tune do you have? I have basically the same set up just don’t have down pipe yet, and not sure what tune to get
ITS A STAGE 2 TUNE FROM STRATIFIED
Maybe engine emergency running
Ur turbo is gonna be cooked bro lol
What happens if u have a pop tune and then get a bov
I saw on a thread that after a few months the guy had issues with the bov
is sound no cts bov , is valve disconect
Is it okay to drive like this ?
We would not recommend driving it around like this no
There's a reason why volkswagen uses a diverter valve and not a blow off of maybe you should research that...
Is that petrol or diesel engine 🤔🤔
this is a petrol/gasoline motor
Thanks bro ☺️
Bad setup, the bov go on when the rev go up, you can hear it.
Common mistake people make is thinking it's compressor surge..its not its called air reversal. Some turbo seals won't like it though. Many are fine with it though.
Compressor surge is a stall in turbo in a high gear low rpm situation say going up a hill. Very rare in modern turbos anyway.
No daña el turbo?
we don't speak Espanol sorry
@@SvGTAPES he asked if it damages the turbo by making it surge
Yes it does damage the turbo with surging
@@Socks3657 thAnks👍🏼
Wow
i envy you
It’s mainly stock? Lol
Sounds good but its pure turbo surge your gonna damage the shaft and bearings on the turbo
Yes this is true
Get a turbo inlet pipe
We have a full intake going to the turbo!
@@SvGTAPES an inlet pipes flow should exceed the surge flow,and surge sound shouldn't be that audible with an aftermarket inlet.
The increased ID of the inlet pipe should absolutely far exceed the surge line,since when that compressed air exits through the turbo on its way back to the intake,that increased ID will no longer cause a bottle neck in outgoing air,even with increased pressure and flow,that air should be able to slide right by the impeller,that's why you don't see these kinds of cars making awesome surge sounds
Curious,what inlet elbow are you using?
Since this really shouldn't be possible with an increased ID in that elbow.
@@luckyhands4995 were
running the cts intake it is a 3in intake to the turbo
@@SvGTAPES the cts intake doesn't run to the turbo,it runs to the inlet elbow,and I can see in the vid it's stock.
I'm not breaking balls,was only curious because when I went full stage 2 including hpfp,I lost that sound due to the larger inlet ID, which I wanted to keep.
When I was stage 1, I had used a "go fast bits" dv+(diverter valve) I replaced the stock spring with a 1 bar pressure spring,allowing the turbo to surge up to 1 bar,or 14.7 psi,sounding quite similar to the setup in this video,surge at lower pressure,blow off at higher pressure.
I miss that sound lol,and even though the cars faster,it sounds way less threatening.
Like I said,wasn't coming at you,was just curious.
@@luckyhands4995 thats wild man you have a lot of knowledge about gti’s and boost barometrics! Thats awesome, thanks for the chats!👍🏼
Fack the golf r i bought does this and i have no idea how to fix it. Idk why tf the previous owners left it like that
Danggg dude thats annoying
@@SvGTAPES All good actually, after doing some more research turns out is is turbulent surge to prevent over boost. Sounds a lot like compressor surge but its not lol
@@hollowoak2610 well thats good!
@@hollowoak2610 interesting i bet it sounds good
Dude a stock vehicle means stock from the factory.. You said your car was stock and then you immediately started naming off parts list.. Including tuned... That would mean your car is tuned and not stock...
*DO NOT DO THIS* It sounds cool but that is actually called compressor surge, the turbo will die a horrible death like that. If you want that sound, get a proper external wastegate.
These are the type of people that tell you it's bad for the turbo, the type of people that don't understand what a wastegate is, I'll give you a hint, it has nothing to do with the sound, doesn't matter what type of wastegate you use.
What if my car doesn't have a bov?. Mk7 jetta 1.4
If it is not turbo’d it wont make the noise
@@SvGTAPES it is a turbo
@SvGTAPES it's a mk7 jetta s 1.4t and my engine looks way different compared to yours
Stock ? But it’s got a down pipe
Full exhaust
Intake
Stage 2 tune
Far from stock 😂
🙏🏻🙏🏻
is this actually safe to do can someone tell me
No. It sounds cool but you can cause issues with your turbo or BOV if you do this. It's like learning to take off a bottle cap with your teeth. Looks cool at parties until you chip a tooth.
