How do I make my wastegate chatter/flutter? Is there a way?

 

I presume you mean the 'ch-ch-ch' hat is compressor surge? It is not the urban myth of wastegate chatter.

You can disable the recirc valve that is put in to prevent it, that will do it, but the contstant hammering on the bearings are not good for them, and in extreme cases it can shock the compressor loose on its shaft, its really not good for the turbo.

Search for compressor surge, its been covered loads of times.

I run my car without a dump valve so that gives you wastegate chatter

 

I run mine with no DV but to be honest the sound is nothing special plus it was mapped to run with one - and it has blown the front mount pipe off twice so I'm refitting the OE DV.

 

Thanks for the replys.
Sounds nice but not nice enough to risk my turbo...

 

Fit a front mount.
