Induction flutter

[Carl123]

Abit new to this but I've seen a fair few that have the flutter when revving etc but mine only makes the whoosh noise couldn't explain that noise any better lol can any1 tell me how or why these vary cheers also I have a forge twintake

You usually get the flutter if you double rev, its the gas dumping or in VW recirculating it. If you just do a big rev you will get a single wooosh.

Some intake are also more prone to hearing the flutter / dump sound.

My itg only gives like a woosh not the turkey noise

I've got an itg on my edition 30
If u build up boost then let off throttle and tap the accelerator peddle it makes the flutter

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

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

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?

^ yes, I thought something similar that flutter w bad, stalling.

Correct

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 .

Think it's normal. Tap the accelerator again just as you come off the gas and you should get the flutter sound.
