  • this has nothing to do with the wastegate. its called compressor surge. There is no such thing as "wastegate chatter" lol

  • @nwfklan That's right. This is compressor surge, or turbo flutter, whatever you like to call it.

  • I have a '97 V70 T5 and i changed the stock air filter for a K&N cone type. It makes exactly this noise and there's nothing wrong with it.

  • That's the air coming back out the compressor intake and can/will eventually kill the turbo

  • And thats has nothing to do with the wastegate.. If he had a wastegate problem he would get boost problems. To much boost or to little.

  • Thats how it sounds like when you have a cone filter, but he has compression surge. Your by pass vlave is blocked or the vac is dis from it.. That is bad for the turbo unless you running a aftermarket BOV.. I Had to get a new turbo cuz that hose was not on my CBV and i didnt hear the flutter.

  • Your all idiots.... anyone ever hear of compressor surge? I have a cone filter on my R and it doesn't make anywhere near this sound. Count on youtube children to give wrong information.

  • this can seriously damage your turbo + manifold

  • @JohnMcLeod1991 talking shite.

  • @Steebod lol ok whatever

    u do it to ur car and see how long it lasts :)

  • @JohnMcLeod1991 The noise that turbo is making is completly natural. Every turbo does it. The reason you don't hear it is because the stock air intake system does a very good job of keeping everything quiet. A K&N or similar sports intake doesn't keep the noise down because the cone filter is not in an enclosed box.

  • @Steebod to make a wastegate chatter u block off the wastegate on the turbo so the air gets pushed back through the turbines making the noise cause ur turbo to have less power in the next gear and wearing out the turbine

  • @JohnMcLeod1991 Why did the turbo in my Volvo S60 T5 do the exact same noise with no modding other than a different air intake then? I would hardly call that chatter, it's so quiet!

  • thats compressor surge

  • sounds good.lol

  • i'm guessing you are running the factory bypass valve but noticed this sound after you put on some sort of aftermarket intake. there's nothing wrong with your car. relax

  • @turbochargedglory I have blanked off the factory bypass in order to cause the compressor stall, I know theres nothing wrong :)

  • Mine did this when i forgot to reconnect the bypass valve control line to the intake manifold after a gasket change. Sounded like a ricer owned subaru. I quickly fixed it :-)

  • @mattp101 oh no, you should not do this, your turbo will be seriously damaged.

  • @mattp101 OMG, finally somebody that knows what theyre talking about!

  • how you get it to sound like that please tell me
