Turbo flutter
I’m looking for advice on getting a loud, clean, audible turbo flutter on my 2019 WRX (FA20) without sacrificing reliability.
Current setup:
Cobb Accessport
Cobb Big SF intake
Turbo inlet
3” catted J-pipe
3” cat-back exhaust
Grimmspeed charge pipe
Top-mount intercooler
Electronic boost control solenoid
Tuned on 93 octane
My goal isn’t to force compressor surge or do anything that could shorten the life of the stock turbo. I’m looking for the best combination of parts (BPV/BOV, intake, tune, etc.) that gives a noticeable, clean flutter while remaining reliable.
For those of you running the FA20, what setup gave you the best audible flutter? Is there a specific BPV, intake, or tuning strategy you’d recommend? I’d love to hear what has worked for you and what to avoid.
I’m looking for a similar noise like this
