How to get super loud turbo flutter with these easy steps.
HTML-код
- Опубликовано: 28 окт 2021
- In this quick video, I will show you how to get super loud VL style turbo flutter. Demonstration purposes only Note that this "may" cause damage to the turbo. And for a car that runs a MAF, it could cause some issues regarding fueling and may trigger a CEL. Some cars will even go into limited performance mode. This is also known as limp mode.
It's also worth noting that it should have a filter for some sort at the end of the pipe. Running with no filter will probably wear the turbo out faster than letting it flutter.
Car used for this experiment is a Saab 9000 with a 2.3 turbocharged engine. Turbo is a TD04HL-15T, so it is a pretty small turbo. The Saab 9000 uses a MAP sensor instead of a MAF, so this won't cause any issues on this engine management system.

everyone talking about the stututu, but listen to that engine take massive breaths under throttle, glorious intake noise
It is also missing the air filter. But yes, they do have an amazing air breath sound.
Working for a turbo reman company, i now see exactly why 70 percent of the turbos that come in have blown out bearings and shredded compressor wheels, because of this video.
Yes but turbo sound cool
Yes you're right most oem ones blows up after bov delete. I would suggest for an aftermarket well engineered turbo like from hks, etc. Or just don't delete your bov make it small instead. Well a small bov won't keep them from blowing up but slowes the process a bit.
what makes you say the 70% comes from this?..what about too much psi?..lubrication?..foreign objects sucked in?
@@henninghellerud My guess is lack of normal maintenance ( like oil changes, air filter changes, etc.), But i honestly dont know exactly, becasue most of the turbines look like they shredded apart from getting too hot and expanding enough to touch the housing.
@@henninghellerud compressor surge induces huge radial stress on the compressor which WILL clap it out
That sound a happy and healthy turbo for life
I just tried to find a good video for a turbo spooling up when you gas, and coincidentally found a video with a Saab T5 engine. Real nice
Yes
As a saab fan, this is super cool
Bruh me too😂
Thought the same thing
Quick way to reduce the lifespan of your turbo. Race and rally cars have it because it helps prevent lag but at a compromise. Blow off and recirc valves are there to protect the turbo.
@Gibbon don't need workshop to remove a vacuum pipe.
@@badly_dubbed2401 No, but most people do, after they killed their turbo...
BOVs help prevent turbo lag by keeping off throttle surge down and compressor wheel speeds up. Rally cars use anti lag to keep the turbo spooled off throttle, which beats up the turbo. Surge is only bad under load.
@@Mastermindyoung14 bov's are there to vent boost pressure when the throttle is closed. Turbo flutter is pressurised air acting against the turbines, essentially chopping it up drastically reducing it's life span.
@@badly_dubbed2401 Drastically reducing it's life span = doing no noticeable damage.
Thats a really cool and easy gadget to get this awesome sound 😍 Personally i would also put on some fine threaded net or smth like that at the end to prevent dirt and other stuff from getting in to the turbine fan and the rest of the compressor housing 🙂thumbs up! 👍
Well, yes. That's absolutely recommended! I never run my cars without an air filter. It's probably more damage from not running a filter than letting the turbo flutter.
@@TurboNerd1302 who needs an air filter, soooo overated. Those OEM Parts are way to heavy and restrict horsepower, thats why I deleted my headgasket. More compression eZ HPs
@@markusluftner8418 no
@@markusluftner8418 true. And if you drive on dirt roads, air cleaners are just a PITA. Keep getting blocked all the time. Makes a ton more sense to get rid of em.
@@alanjm1234 exactly! Also life hack for direct injection engines. Just drive in the desert without a filter. Cleans the carbon right off the intake valves. No need for expensive wallnut shell blasting shenanigans, if you do this simple trick.
Dang boi, sounds good 😂
From what I’ve heard from many mechanics, closed throttle compressor surge (when you let of the gas a stututu) is fine for the turbo and won’t increase wear significantly, the issue is open throttle compressor surge (foot to the floor and you start to stututu) it’s very very bad for your turbo, it’s common when you block the bov on a Subaru, haven’t heard of it being an issue on other cars tho
open throttle surge isn't so bad on the turbo, I'd say its bad for the engine, because you're forcing in more air (on throttle) than the car can make use of. Blocking a bov on a subaru shouldn't cause open throttle surge, it's likely someone blocked their wastegate line, which would prevent it opening and cause overboost, which will likely cause problems very quickly
@@strider5119 yeah, ive seen a couple videos of subarus that go stututu having open throttle surge, that would explain it though.
This is also the reason why many automakers don't not use a BOV.
@@strider5119 Problem with open throttle vs closed throttle is the exhaust side of things , closed throttle you dont have much pressure but open throttle you have full backpressure , effectively twisting the turbine(which shouldnt twist) pushing away the oil film from the bearing surfaces.
And you should know how a turbo with shaft play works
@@BMWe-ed2tn yeah but that's a different issue altogether
i remember using a bottle cap to block off some pipe when installing a aftermarket blow off valve on my old nissan i miss that car
VERY NICE - BORAT
As a tuner , Big turbos should not flutter . Small turbos can flutter seen the psi making the flutter sound is nog high enough to really damage the turbo , so what you said it not correct that they flutter like ( BIG ) turbos . They should not flutter at all , Turbo flutter is created by unreleased air going back into the turbo because it has not other way to go like say : Ricirculation valves , wich put the air back into the circuit , or blowoff valves who will blow it off into the atmosphere . High psi turbo flutter will therefor put alot of stress on your turbo axle / blades . So for a small turbo like yours ( and mine ) its fine . Im running a Vauxhall mk4 OPC II z20let 289 HP with VXR turbo , wich is relativly small aswell . and the only thing is did it buy a recirc blank plate , wich closes all circuits aswell . that already gives you loud flutter noise and is perfectly fine for what you have . Hope someone learned something from this , Genesis out !
I thought turbo flutter when the throttle body is closed is fine, but flutter when the throttle body is open is really bad?
@@PotatoTornadoable Having compressor surge on open throttle has nothing to do with having a bypass or dump valve or not. It is caused by forcing too much air in to the cylinders so air can't get anywhere. So if you hear flutter on open throttle, lower your boost before you break it. Flutter on off throttle, don't worry.
@@PotatoTornadoable has nothing to do with it , its the air to goes back against the turbo scoops
In other words don't be an idiot like the guy that posts the video and delete your blow off valve. If you can't run a blow off then run a recirculation valve. I love people that claim to know about turbos then wonder why they keep going through engines and turbos!
These "as an X" comments are getting to me
If i remove my brake pads will it make the turbo flutter ?
i think that 90° angle aluminium pipe sounds nice
Nice tip bro, what size pipe did you use?
Probably 2.5" inlet to a 3" pipe
Info: I have a 99 Saab 9-5 wagon. Has a b235r with a stage 2 tune troll r (knock off). Upgraded injectors and a HPS Air intake. So in order to do this you need to delete the diverter valve and bypass a BOV? And also have a MAP sensor not a MAF sensor? I wanna do this but don't wanna do it incorrectly. I feel like I have everything to do it except a MAP sensor and the pipe obviously.
On a 9-5 it's not really possible without causing problems with check engine light and lower performance than usual as the 9-5 has a MAF sensor. You cannot delete the MAF sensor on a 9-5 and expect peak performance. Either get a non-MAF car or run the factory setup for optimal performance.
@@TurboNerd1302 what about the saab 9-3? With the 2.3 L T? Could this work?
@@maxjameson7695 same engine
@@TurboNerd1302 It _is_ possible to do. The way to do it on a Trionic 7 engine is to move the MAF sensor to _after_ the turbo. It works, but the MAF is not designed for pressurized air which means it could cause loads of problems on its own.
Deleting the air filter is going to shorten the life of the turbo a lot since even tiny sand particles hitting the blades will cause damage due to the high speed of the turbo.
Also, the "flutter" is due to air being pushed back slowing the turbine way too quickly and this can also cause damage to the turbo.
wouldn't it be possible with an aftermarket ECU?
Yes, do this if you want your turbo to die much sooner than it should.
Much sooner = if it does any damage it's so minimal you wouldn't notice.
this is gonna blow up soon
50k later at 1.4 bar of boost and still going strong.
@@TurboNerd1302 I meant the video lmao not the engine its a SAAB it won't blow up lol
Nice
BOV and Wastegate are different features.
Blocking a wastegate will cause the turbine side to build excess pressure in the exhaust manifold and when the turbo is at boost capacity, the stututu is the turbo spinning too much boost and causing the exhaust to back up. Essentially forcing the compressor to slow down while the turbine wants to go faster. This is when a turbo bearing goes into torsion.
BOV is the release of pressure from the compressor side/boost pipe when lack of vacuum returns to the BOV.
Don't block your wastegate, you might spool faster but at the cost of a turbo over time.
BOV releases boost built up behind the throttle body, and the Wastegate release exhaust built up behind the turbo.
It's not the exhaust backing up, the wastegate is not blocked in this video, it's caused by the throttle plate closing and the turbo moving into the surge zone which is low airflow (because the throttle is closed) and high pressure ratio, it does not slow the turbo down.
What’d you do about the apc vaccum lines ?
my car is naturally aspirated
"Mad hectic Turbo Flutter" 🤣
we call it a dose but I love that bro 🤌🏼
my civic has a BOV and still flutters, i only have a cone filter on it right now... i will probably do this... and give it the big stututus
what about a disel car tho is it the same
What i do t have BOV but electronic wastegate? And i cant find divertor sensor either ...simple TSI engine
don't touch the waste gate lol.
I'm not going to be another person to say you're going to destroy your turbos prematurely, but I am going to be the person to say you are wasting energy to create a cool sound. After a throttle plate closes your charge pipes go from a state of high velocity high pressure, to low velocity even higher pressure, a diverter valve will take the excess boost and recirculate it back into the turbo, so during a shift the turbine can keep some energy. A blow off valve dumps to atmo so instead of preserving the energy it just dumps it allegedly to prolong turbo life but usually to sound cool. Compressor surging (turbo flutter) is the sound of air rapidly slowing the compressor, causing the need to spool up again in next gear, ironically providing worse performance than even a BOV. Turbo damage or not, I would not do this on any application you intend to compete with. It's more of a cool factor for cars that aren't actually really cool. My V10 TDI flutters like crazy because my anti-shudder valves are so caked with carbon they actually act like a throttle plate when I let off the gas and almost entirely seal the intakes..... no throttle body on a diesel whatcha gonna do xD
Touareg?? Legend
@@Ali-sh4ib there's short on my other channel meanyhead no X's i dreamed of owning one for a decade lol since Repo Men the movie
Nice book
You're wrong and probably crosseyed
Meanwhile in reality it's been proven that running a valve or not does not change the speed of the turbine when you lift off the throttle, if it did it would not be so common in race and drift cars not to run valve, most obvious being rally cars that constantly flutter off throttle due to anti lag.
@@DriftNick listen to what you are saying. What do you think anti-lag is? Cite your sources
In what universe does that sound good?
Hi! Is this bad for the motor or the turbo? I’ve heard that if you do something similar it’s bad.
Hi. Some say its bad, others say it does not matter. Some car brands even has turbo engines without blow-off valves from factory. So its really impossible for me to say. I've tried this on many of my cars, and have never had an issue.
The sound is compressor surge where there is to much air in the intake and the only way it can go is they way it came and then the blades catching the air coming back out makes the sound and this also makes the turbo a little less efficient and can potentially make the turbo work harder and maybe making the turbo less reliable but heaps of people do it and it doesn't affect it to much but many people like to fight over this, hope this helps
turbo flutter is only bad when it's happening while on the throttle
@@scaff3887 yeah that's what I forgot
Turbo flutter is bad when it sounds bad usually up to 15 psi should be the limit too much will mess up the bearings

There's a reason Saab failed, let the Frankenstein monster die already
What did you do with vacuum hose to dump valve? Just plug it with a bolt?
Yeah, just plugged it.
Blow off valve has purpose guys
@@mariefagan5743 also the air filter before turbo xD
@@Mega1ok hahahahha true.
Don´t worry, that turbo won´t last 5000km. Probably now is already dead.
I have an alloy 90 degree bend off the front of my turbo it sounds similar, didn't have the room for a straight one and fit a filter.
Yeah, there is pretty much no difference there. The length, diameter of the pipe and size of the intercooler changes the "tone" and "length" of the flutter.
@@TurboNerd1302 Well actually there a massive difference there since its 90 degrees off the front of my turbo and a filter on it rather than a straight one...

Hi. A diesel usually don't have a throttle body and will make it difficult to make the turbo flutter. Check out MCMTV2's video "Compressor Surge Explained [GO FAST BRETT]" for more information around this topic.
you are propably talking about interbal wastegate right now!
its a different thing than a blowoff valve
diesels dont have throttlebodies so they dont need bovs!
How much mm in this pipe
Hope a stone doesn't get in there 🙏
Thats when you buy a metal net to put over the opening of the pipe.
Will it work on a Mitsubishi carisma did 1.9
unfortunately no, diesel engines don't have a throttle body
What is the name of it??
compressor surge XD
Where is the intake filter
Guys its possible to do on any patrol turbo car lol
Diesel or petrol engine?
Compressor surge is what you are creating because you’ve removed the bov. The air pushes back into the fins slowing it down. It damages the turbo. Race cars do it because they have extra turbos on the ready to replace when it developers shaft play.
Why wouldn't race cars use a BOV to prolong turbo life?
@@jetstream454 Because they can afford it.
mate, im not sure where you got your info from, but you are completely incorrect. no damage is done to the turbo by deleting the factory Diverter Valve (not bov, bov is to atmosphere)
@@fgdgrddsew2 Right, but would it not be more efficient to simply fit a BOV which also keeps up compressor speed?
@@fgdgrddsew2 that still doesnt make sense...just because they can affordit doesnt mean they should do it, there is no advantage to letting it do it
Bigger pipe = PROFIT!!
Bu sistem Saab 9 5 e olur mu?
What how i need this
Is it broken?
So if i were to do the exact same thing to my turbo, would i need an air filter to prevent anything from getting inside the turbo and would it reduce noice once its in there?
Did you have an air filter on it now
This video is just to show what a dose pipe is. You should definitely use an air filter (which this guy probably did after the video) and it likely wont lower the noise. If it does, wear it, because you're far better off losing a tiny bit of noise in exchange for a filter.
hi bro does it work in diesel too? I have a ford mondeo 2.0 tdci
Sadly no cause 99% of diesels don’t have throttle body
Please do not mess wit the BOV
Why not?
Where is you air filter
I wonder if anyone done this to a f150 ecoboost ?
If I do this to my car, but I don't race it or nothing ... Just drive it casually and rev it a couple of time, will my turbo still breakdown/damage eventually ?
It's impossible to tell. Some "experts" say that this will most definitely ruin the turbo, while others (like me) have ran their turboes like this for thousands of miles without any issues. Many factory turbocharged cars didn't even have blow-off valves or bypass valves. But as stated in the description, some cars engine management systems will not like turbo flutter.
no, you'll be fine. Unless your car has the cheapest, nastiest turbo in history, it'll be fine.
You better put an expensive thic oil 5w40-10w50 or say goodbye to your turbo bearing.

dus psi make a turbo flutter more or how does that work?

You can increase flutter by changing your intake pipe, upgrading your intercooler/piping, or running more boost. Different combinations of the above make different sounds
You can't run a turbo like that long term...unless you like replacing turboes often.
yup , turbo flutter is just another term for compressor surge which like you say kills turbos quickly and also creating turbo lag.
Not true. When flutter/surge happens on closed throttle, there isnt an issue, since at that point its just really a closed pipe and a free spinning turbo making chopped air. The problem occurs if it happens on open throttle.
Funny never been an issue for me in over 10 years.

It’s safe but because he blocked off the pressure relief valve the air pressure get forced back through the turbo charger when the intake closes off.. causing the fluttering sound because the airflow is becoming bottlenecked. This leads to blown bearings and generally excessive amounts of wear and tear. In short unless you want to replace a turbo charger and lose performance don’t do it
