The stutututu in a turbo can actually effect performance, basically, there is low pressure in the manifold and high in the turbo. It has to go out somewhere, so it goes back out the turbo in sections (there is a better word than "sections" but I'm to lazy)
Funny! I'm training to be a pilot and we have to learn about wastegates (blow off valves) for our airline training. So it's brought me here as I knew it was the same concept. But yep without a blow off valve (wastegate) to release the overpressure when you let up off the gas, the air backflows through the centrifugal compressor, and as the compressor is spinning and already trying to suck in the air, it creates a chopping of the air, which actually causes pressure spikes over the compressor blades resulting in wear over time. But it's unfortunate because the "TSU TSU TSU" sounds so good. And also even with a blow off valve there's a performance payoff, that is if you do not route the blow off valve to release the air just in front of the compressor, which would be far more efficient, and reduce turbo lag when you reapply the gas! Cars and Jets ain't too dissimilar haha
this is surge, not bov. this tu-tu-tu myth needs to stop. NO BOV OR WASTEGATE makes this sound. this is undigested air that tries to counter-spin the turbo and clueless kids all over the net perpetuate the 'coolness' of what is essentially the sound of a turbo being hurt. whenever you hear this sound, it's surge. plain and simple. and unless you got a racing car that has everything replaced or rebuilt after each race, you don't want this sound coming from your engine bay.
how tf you gonna counter spin a 100k+ rpm turbo? unused air passing back through turbo simple as that. if the person is doing it for fun they obviously understand what will happen eventually.
@@lukesmith112 I'm 2 years late but it doesn't counter spin. It CAN'T as the turbo has too much inertia, but it TRIES to counter-spin the turbo. It's like putting your hand in front of a fan. You can try to stop it but you'll hurt both your hand and the blades before it stops
@@aggro_beat It's nothing like putting your hand in a fan, it doesn't even slow the turbo down, people have tested it, there is no difference in turbo speed between running a blow off valve and running none after you lift off the throttle.
Turbo flutter does not hurt the turbo, it's not trying to counter spin the turbo, the only clueless kids are the ones that think that happens, also the sound in this video is a blow off valve.
@@doppelganger7585 you are asking as if he knows that bov that is... did you see him go to the engine and look at it ?? Did you see him ask the driver what bov that was ??
@@doppelganger7585 do you think the person who took the video knows what bov the car has ?? Do you think people watching and listening to this video know what brand bov that is ? Do you realize how MANY BOV's there are in the market and ALL of them sound different from turbo to turbo ?? Do i need to ask more questions before you realize that your initial question was dumb ??
At least he HAS a bov, unlike Millennials today taking the BOV OFF to get the aweful STUTUTUTU compressor surge sound. They think its cool and think its not hurting the turbo. That shows you how little they know about turbo's...
@@bulletdrop436 it IS ... ruclips.net/video/FwzUffAuQyc/видео.html & ruclips.net/video/vuyJ5jD3r0o/видео.html This is WHY turbo engineers designed that thing called a BYPASS VALVE OR BLOW OFF VALVE to prevent back surge against the turbine wheel ... That back surge will throw the shaft off balance and blow out the seals ...
@@ACommenterOnRUclips it hurts the turbo so little that it doesnt count so basically bov just makes the pshhh sound and makes turbo lifetime a little bit longer
Nice Yamaha
Good honda
Sick Mitsubishi
*stares in Toyota*
@BroknWingedHawk 777 Yamaha had some input into the flow characteristics of the head. They did not design, produce or manufacture the 2JZ.

well jet engines are called turbojets..when you said pilot training i thought you'd be talking about turbo normalizers haha @@Dragonborn2k
@@Dragonborn2k Blow off valves and wastegates are not the same thing, they are not interchangeable.
It can effect performance, it reduces lag because all the boost pressure isn't lost out of a valve.
I LOVE THIS VALVE SOUND 😍😍😍
Amazing car
Vicious 😮❤
That's not a blowoff valve , that's a flutter lol
Ottima melodia
Hell yeah bro. I need specifics.
Big single turbo?
What exhaust?
What bov?
🤙fuckin shweeet
Little turbo, stock exhaust, Hks sequential
Doesnt matter, you cant afford it anyway
