Induction flutter

<< < (2/3) > >>

rich83:
The on full throttle boost flutter you hear is the wastegate regulating boost.

Pikey Motorsports:
Depending on your recirc valve setup varies on the sound.. You will get the noise all the time if you have a forge recirc with a strong spring

john87:
As satisfying as it sounds, I thought that induction 'flutter' is a sign of compressor surge? i.e. compressed air being forced back through the turbo's compressor vanes, due to the DV setup not opening enough when required?

Hi .
Old thread but hoping for a response. I've  just fitted a forge twintake to my BWA engine GTI K03, it's totally stock apart from the twintake  .
I don't get any chatter unless I tap the throttle a few times on boost other than that it is just a woosh! And darth Vader noise under load Is this normal. Was thinking I may have a faulty DV or something. after reading this thread am I correct in thinking this is a good thing that I'm not getting loads of flutter or not .
