Without physically seeing/hearing the car, have you checked all the connections that you will have touched when you changed out the turbo, BOV and intake?

 

Ya, I've checked everything. Thats why I was wondering if it was a BOV or Wastegate not doing right with the turbo.

 

Does it do this everytime you shift?
Whats your full setup? tune and everything.

 

No like I said its just at some times like daily driving. My setup is in my signature

 

Under what conditions does it happen? Can you readily reproduce it? If you want to rule out the BPV, you could borrow one from another member if they're local or reattach the stocker.

 

I'll try to remember to bring my camera with me tmw while im driving and try to reproduce it.

 

I have the same turbo flutter from time to time, but only after I give my car a Red Bull...

 

I really don't think it's proper turbo flutter (air slamming into the vanes), I think it's just some other noise.

Sounds identical :21 and:29

 

That doesn't seem like proper turbo flutter to me since it sounds like the car isn't not going from WOT to no throttle, it sounds like a gradual decrease in throttle. Do you know if that Evo is an MR by chance? I wonder if the sound is the transmission. Have you checked in the Evo forum for any reports of turbo flutter or BPV problems?

 

thats the wastegate lol.


sounds nice

srt-4's do it like CRAZY

 

That is a loud as hell wastegate for a more or less stock car .

 

That is is MR he says it's bpv flutter from not enough pressure but he has ams intake intercooler and pipes and downpipe with agency power bpv

 

If he has an aftermarket BPV, it's not surprising it sounds the way it does coupled with an intake and presumably a tune for more boost. Do you know if the 5 speed cars get the same sound as you do?

 

No im not sure but I'm also running a short ram, IX bov, and widemouth downpipe. So maybe its normal?
