Thank you!

[Pirvu Eugen]

Nobody?
Just curious!!

[Rusty]

The exhaust is so loud, you can't really hear anything else

[Pirvu Eugen]

Sry for that!! Is just the downpipe...but that high pich sound? What you think is that?

[Pirvu Eugen]

This sound apears only on higher rpm or iff i blip the throttle as you heard on the video

Sorry I don't know if it is meant to make this noise, sounds aggressive though, kind of like an S1....

your sound is coming from the turbo side of the engine and not the intake??

[Pirvu Eugen]

if is the intake, what will be the cause?
Thank you!

[sailaz]

would say this is surge sound from compressor wheel, but you say that cold side is not connected !! would like to know what you will find ! so far it looks like a mystery

[Pirvu Eugen]

Indeed!!
I will make some more tests!!!
I will let you know!!!

What turbo is it? If you have no exhaust maybe it is turbine impeller whistle combined with wastegate chatter.

[Pirvu Eugen]

Thank you Billman!!
Is Albert's turbo, Wagner em and oem s2 downpipe.
The cold side is not connected... I just started the engine to see... Oil pressure, compression, oil leaks... Etc. And i noticed this sound.
Thank you!

I think it's just the sound from the turbo because it's not all piped up.
