330hp Saab 9-3 Turbo flutter

already have the proper blowoff now

😄😆

If you’re getting flutter on a regular basis, you should consider installing a BOV. The flutter can cause excessive wear and tear on your turbo. On the other hand, if you’ve got a performance non standard exhaust system, that’s a good thing 🤔

I believe its a Maptun atmosphere one but it doesn't open fully which makes it flutter

@@Grandpasaab thanks buddy! Enjoy and speak soon

if you have BOV that opens at the very "end", when boost is just almost at the top, and also conical air filter You will have that sound too. I'v got stainless steel inlet pipe, that air filter and HKS Bov. While driving just casually it goes turbo flutter, but with high boost its turbo flutter + bov sound.

@@TomaszSynAndrzeja Ye well my BOV just doesnt open in time so i get the flutter. with a recirculating bov from maptune its no flutter

@@Grandpasaab so we can say bov task failed successfully.

Drive around :)

Chinese td04, Dion gelooft zelfs 5cm

@@Grandpasaab meen je! Ik heb op dit moment een volvo k24-7400 op mijn volvo v40 zitten. Deze heeft een 6cm behuizing.. turbo zou goed moeten zijn voor 350/60pk. Maar had voor mijn gevoel meer power met mijn 7cm 18t. Maar lijkt dus dat de behuizing niet alles zegt. Wel heb ik maar een 2.5 inch uitlaat op het moment, denk je dat een restrictie is?

@@bartjongedijk3791should be fine I would try 3 inch tho

No, like many say its bad. I like it so I dont care but the reason why mine flutters is because the blowoff isn't opening properly

it has a BOV but not working properly, already have a working one

@@Grandpasaab That’s good to hear, you don’t want to stress your turbo on that awesome machine 🤔

@@venom6848 YOu can hear the proper BOV on my Nurburgring laps on my channel :)

Yes but good for my ears :)

Yep hope he has an extra turbo

@@valis0053 When it breaks there is space for a bigger turbo :) this is just a chinese TD04-19t with to small exhaust house

How is it bad for the turbo if it’s just a bov and prolly cai

@@brendenlehman6665its bad for the turbo because the BOV is not opening in time or fast enough (to dump the excess air) and the compressed air now is now stuck in the intake pipes+intercooler has no where to go (throttle plate close), so it heads back towards the turbo where its 'chopped up' by the compressor blades which makes the STUUTUTUTU noise (nice). This can stall the turbo causing lag, but worse, its puts stress on the bearing/shaft. Who knows how long this can last, maybe a long time for lower boost!?!
