Hello,

I've just noticed a sound on the right side of the car.. Or atleast it sounds like it. it's only noticable with the right side window open and after I release the gasspedal after my bov.
It's not happening all the time, mostly when it has built boost at around 4-5k rpm. It's a really sharp and quick pssshp sound. Any ideas? I'll try to get it on video and post it here.

It runs 21psi boost, stock turboes.

Thanks.

EDIT: Maybe this should have been in "Troubleshooting".....

Wastegate rattle if from the right of the bay.
But it sounds more like air...? And not a rattling sound...

I watched some videos of a wastegate rattle.. And it really doesn't sound like that. But I'll try to get it on video tomorrow..... But what do I know... For all I know it can be... But to me it sounds like it's air that blows off after i let go off the gass.

Might be my speakers but I can't hear anything.
Hehe, it's at 5 and 9 seconds. It's a tiny pssp :tearsofjoy: It's not always been there.. You can't really hear the BOV or the sound that comes back from my cones in this video... But I'll be replacing my outlet and inlets very soon.. So maybe I'll see or figure out what it was :D
