I rebuild turbos for a living, and what they're saying is pretty much correct. The thing is though, 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.

The flutter (sututututu) noises are caused by the throttle snapping closed and all the air thats already heading to the intake gets stoped and fills up the intake pipes all the way back to the turbo, and forcing it way through the compressor fan while its still spining at its ridiculous rpm, forcing the compressor fan to cut through the air, thus making the flutter noise

so what do you guys think, with flutter caused by throttle closer as Jimmy points out above, would that hurt the compressor or not? If the BOV/BPC was set up correctly, I thought it should vent all that excess pressure between compressor and closed throttle plate, and there would be little to no air having to escape through the spinning compressor wheel, and hence no flutter?!

Thank you for clarifying, now i can show people this video instead of trying to explain why they're wrong. The only thing i noticed is that with no bov on my mr2 i actually had a MORE RESPONSIVE turbo while changing gears...when i ran a bov there was MORE LAG while changing gears at WOT.

You trust the same people that made said turbos before BOV's were a thing? You do know that half of these companies popped up after the car craze that fast and the furious caused. Go to any company thats been dealing with modded cars from before that and they'll tell you they arent needed. Its a gimmick to sell you something you dont need. You do know that BOV's are relatively new. OF course a company that makes turbo's, BOV's and other things is going to tell you need a certain part so you'll buy the part. Take a look at all the older cars with turbos. NONE had BOV's. None of em. They all ran just fine. As a matter of fact a neighbor still has his old grand national with a turbo as old as I am that came with from the factory. No bov ever and the car still runs strong. There is no NEED for it. If you want one. Get one. But its not needed. If the car is surging under load its a tune/mechanical problem. Not the lack of a BOV.

squishypitbull this is the stupidest comment on here. They also didn't come with air bags or seatbelts at one point. Doesn't make it a better idea. There's a reason EVERY factory turbo these days comes with a blowoff/bypass/recirculation valve. "My neighbor, friend, sister's brother" stories... Always fact based right? STFU.

Some high boost setups will compressor surge. Especially if you don't reach peak boost before you release the throttle. The BPVs in these setups are adjusted to stay closed during spool until that high boost target is reached. So when you release the throttle at partial boost in these setups you get "surge". This is the only time compressor surge is acceptable to me. I've been building and tuning engines/cars for over a decade.

I can’t stop looking at that perfect dashboard lol a r32 with no dash bubble

THIS CAR IS LAUGHING SO HARD AT YOUR DRIVING SKILLS!! Great effect tho. Great Video :D

If you're getting surge on boost its usually because you are not limiting low end boost, big turbos don't like running high pressure ratios with low flow . Which would be right in the middle of efficiency island of a small turbo. This why a lot of setups ran a small and big turbo, yes the small one can spool up quicker for the low end but it can also sustain more pressure at lower flow allowing more boost at low revs without surge occuring. The damage you can cause by surging is primarily to the thrust washers particularly on journal bearing turbos. When the shaft bashes back and forth. If you run oil good pressure and have tight tolerances the shaft can't move and pick up as much speed when it moves back and forth which is what is going to kill the turbo. I think smaller turbos are more susceptible to damage since they typically don't have the relive holes that you see on big turbos and smaller turbos in general are just cheaper and may not have the same safety margin as a big turbo might.

Mark your an absolute legend I love all your content and your tiktok keep it up boss

LMAO, This subject seemingly will never die! As a 25 year Veteran of the Melbourne Boost Car scene i've been absolutely gobsmacked by the vastly differing opinions by those in the know about something that in essence Is mechanical science. My real fascination is with the differences of opinion coming from the guys at the very top of their respective specialities ie: VL Turbo guys, Rotary Turbo Guys, the XR6 Turbo crew, and of course the GTR and Supra workshops. The mechanical science is simple! Its not "Good" for the turbo! but Its not going to kill it overnight either. But what's very interesting to me, is how much the boost car scene has evolved into various sub cultures! Way back in 1996-99 Era when the bright orange MAZTECH RX3 13B Turbo was running 9s (Unbelievably fast in 98) it was all about extracting as much power as possible, but in 2017 making power is piss easy if you have the money, so now other factors seem to be desired. I've had many serious conversations with certain "Younger" individuals that in all seriousness spend mega dollars in search of the "Perfect Sounding Flutter" NO BS!!! I recently asked a younger guy if he had a blow off valve installed somewhere in amongst that harmony of dosing, fluttering, external gating, devices? To my utter astonishment his reply was simply "Na bro, i'm not really into those sorts of noises yeah" ok now i feel old :(

To summarize - Compressor surge when on the throttle is terrible and can kill engines/turbos. "Flutterdumps" (no BOV with boost reversion out of the intake) when off throttle/throttle closed is slightly worse for the turbo bearings than running a BOV, and will slightly reduce boost response between gears. It does sound fuckin' mint tho hahaha

I think on boost flutter could be a little worse because it's pushing hard on the exhaust side at the same time as the intake side is slowing the compressor wheel down. A bit like being on the throttle while braking wears the pads and rotors more than if you were only braking. If you shut the throttle there is no exhaust gasses pushing on the exhaust side. But on boost surge would create opposing forces. But then again that would only try to twist the axle witch it could never do anyway. But considering the angle at witch the force comes on to the blades (pushing from the side) I don't really see how it could effect the wear of the turbo, because it would require the axle to move enough sideways to break through the protective oil film and hit the bearing surface. If there is any extra wear I don't think it would even be measurable.

Thanks for the very informative video!

People dont realise that a turbo technically stalls as air pressure drops around the blades when the throttle shuts and no blow of valve is there to allow all the built up air to escape before turbo. When the throttle shuts and all that pressure comes back through the turbo it causes the blades to loose grip of the air due to the low air pressure and making it spin at the same speed without actually making any boost. The turbo blades then eventually grip back onto the air when air pressure rises around the blades again. the sut sut sut noise is created by the turbo constantly loosing grip and grabbing in short matters of time.

You're talking absolute rubbish. The SOUND is created by high velocity air flowing back through the tight clearance between the inducer circumference (blade tips)... and the compressor housing. Same principle as whistling with your mouth.

always i have a "noncar-friend" on my urs4 and when it flutters and i say to my friends "squirrels escaping..." and my friends look me with weird look in his eyes like "wtf dude?" :D

I was always told if it does the flutter while on the gas it is bad, if it is happening when you let off ONLY then its okay.

My 1.9 jtd turbodiesel did that sound when my VNT valve went bad. Didn't know such small turbo can do it. It was cool but the car was almost undrivable, and in the end I found it literally spit some oil into the MAF and air filter :)

LOL! This sound is very funny, I prefer it with the priority valve open.

Turbo surge can also be your tune! Two reasons are,too high of a boost level at too low of an rpm, and even if in high gear and high rpm, your throttle body percentage (amount open) is not at WOD so partially closed will add resistance to the turbo and cause higher boost levels but would be a “false” reading because the turbo’s flow is maxed out at the throttle body instead of the boost pressure being maxed out at the cylinder or behind the intake valve.

Very good information... love the car

I like a loud whistling turbo and a violent blow off valve :)

I love the flutter sounds

I have had my 180SX for 21yrs and I get some flutter and love it with my GFB dual BOV I have it plumbed back to the inlet of my turbo to help keep it spooling when I go full boost there's no flutter only low to mid throttle.

"All the cards flying through the air" is very much due to the BIG ASS fan in front of the car. If you look closely, the car shutters when going off throttle which causes the stack of cards to move enough for the fan to blow them away. I find it nearly impossible for the boost pressure to come out the inlet side of the turbo. At that point it would HAVE to make the compressor wheel turn backwards.

Turbos spin at 100,000rpm, it cannot suddenly stall and go backwards.

Compressor surge is the sound of the blades chopping through the air that is being forced back through and out of the intake side of the turbo. Not good for the components of the turbocharger but not going to immediately destroy anything either.

Yes, what you are saying is true-4.27, putting a little stress on turbine when flutter started. I would say the principle in water hydraulics- that if you try to swim against the stream it would put more stress on my body or joints. In real world, if you have the money then turbo sounds matters than turbo longevity.

4:46 You don't think the vibration/stuttering/shock from the compressor surge attributed to the loosening of the compressor wheel nut? Gotta say I completely agree with almost everything you said. I really dislike the noise of surge so I always run plumbed BOVs. Each to their own :)

Loved the video, I know exactly where you guys were filming this ( cause I live nearby) & the traffic there is shocking. Wonder if this is similar to how a diesel flutters or dose. But they don't have a throttle body of any kind as they run rpm from the fuel pump, so what's the compressed air getting stopped by to come back towards the turbo? The valves just before the combustion chamber?

heck yea this is one of the bes flutter sounds!! ,, sounds amazing !! 😀👍😀👍😀👍

Compressor stall is something inginerds work VERY hard to prevent in most scenarios. In severe cases it can take chunks out of compressor blades.

Here come all the 12 year olds saying "I have a gtr and my dad says it's the sound of the blow off valve"

the first flutter was devious

Thanks for this valuable information! I was slightly worried about my turbo after my Diverter valve failed on a recent road trip resulting in compressor surge / Turbo Flutter. I ended up driving about 400 miles with this condition and I didn't really seem to have any boost lost. I was just worried about the stress it might of caused my turbo. Since this owner has been going DV/BOV less or whatever and intentionally causing the flutter I'm guessing the 400 miles I did like this before changing my DV valve to prevent Flutter didn't cause any harm. A different youtuber made it sound like it was pretty harmful on bearings hardware.

Nice vid, but you did sidestep the point that compressor surge when on throttle is bad, because you're trying to spool the turbo on the hotside but the compressor side cant push the air, so it puts the turbo under a lot of stress.

A mate of mine has the Mk7 GTi we noticed this is only during econo mode....... When in sport it runs like a beauty

My twin ball flutters like crazy, Even granny shifting at 2k around town.

4:50 I guess you could say his turbo.... hit the fan?

i had a mitsubishi 2.0 engine NA that would make a farting sound between WOT shifts and everybody thought it was a turbo. All it had was a $1 ebay Apexi knockoff coffee can exhaust and no turbo but it sounded MAD

Route a boost gage to the compressor housing to see how much pressure it is seeing when the surging occurs? That noise could be interpreted as boost spike, maybe? Which would mean unnecessary stress to turbo internals. Still gonna send it though... (just my opinion)

Love it!!!

I had rocks in my head :(

I'm just here for the sssstu tu tu tu..... 😆

Hey guys. Y’all explained this great... so if I want this flutter, should I just delete my blow off valve?

What you think about mounting a bov to an exhaust? When you shut the throttle all boost go to spool up turbo and also backfire

Is that car allowed on the street because it has a aftermarket steering wheel and there are legal on Australian roads

The flutter is a result of how hard your blow off valve spring is. My BOV spring is is full hard, so I get flutter even at very low speeds. Its not harmful to the turbo at all at these low speeds, because as soon as I put my foot down and generate full bpoost there is enough pressure to open the BOV and release the air so this higher dose of air doesnt hurt the turbo.

Yeah same. I was confused with the flutter sound being bad cause my flutter comes from my bov letting air out in a flutter, I think it's supposed to simulate the compressor surge sound? Someone correct me if im wrong.

🤔BoV and BPV needed during high horsepower applications.... staring at Subaru's Type RA that they developed with prodrive.... that flew through goodwood with ease and no problems....

A lot of reputable tuners say it effects your thrust bearing.

I have installed blow off valve spacer in my Fiesta ST 1.6 230 hp for the whooosh sounds and even though everything is installed correctly, somehow i get the turbo flutter upon releasing the throttle which shouldnt be the case. But i quite enjoy it, question is... is it safe for the stock small KP39 turbo? :D

I have a question, if the air is coming back out of the turbo will that affect the MAF sensor if it is set on the intake side of it. Just thought the car would be regerstring that it's still getting air coming in when it isnt.

if u have a nice turbo its not gonna hurt it that much but if u have an old turbo or china turbo just run a blow off valve it is cheap and still sounds cool and can extend the life of your turbo.

awesome !

Depends the turbo dudes. With anti surge turbo you will not ever brake anything with flutter. Its not turning the turbo wheel backwards but the trapped air hits back the compressor wheel cause there's no elsewhere to go. So 2 things will go wrong brake the shaft if the shaft its not that strong or destroy the wheel wings on high amount of boost. I've seen both of them situation.

Turbochargers are fundamentally centrifugal pumps that are driven by a turbine. Most other centrifugal pumps can be stalled for days without ill effects.

Good sound

as a owner of a car that has epic compressor surge here are a few tips. 1. it doesnt fuck your turbo 2. never blown a turbo due to flutter all my cars have been 20psi plus 3. more boost more noise

This is great information. So why wouldn't you put dual BOVs? One at the intake inlet where it typically is mounted and one near the FMIC like most of the Supra and GTR guys.

set the blow of valve where it should be and size it properly and all you will here a slight rush of air and turbo will not be rapidly slowing down and you wont have shaft nuts coming loose on your turbo. its not unavoidable. But it does sound cool. but whoosh sounds fast.

But if the compressed air goes back out the compressor blades do the bearings take any signiciant wearing?

On others it may not wreck them but fuel economy and general performance (or lack thereof) goes up the sh*t. Usually the same numb skulls who argue that bovs are necessary are the same idiots on forums asking diagnostic questions like "my car's running sluggish and fuel economy is out the window, does anyone know what things I should check for incase my engine's blown or something?" my responses is always a question does it have an aftermarket bov? if the answer is yes I instruct them to check for a brain 👍
