Understand the destructive difference between normal bov venting and compressor surge (flutter)
Diagnose causes and implement solutions.
Learn what causes a blow off valve to flutter
This video gives an example of the sound of compressor surge/wastegate flutter/turbo flutter when lifting off
As it shows in the video, the sound is caused by air moving back through the.
The flutter is the sound of the air being forced.
Edgy correct me if i'm wrong but your bov setup is just like my truck's trd magnacharger setup that has an internal bypass valve that recirculates boost when at low load.
Failure usually happens in one of two ways
The valve gets stuck open (creating a boost leak) or the valve fails to open (causing compressor surge)
Both have distinct symptoms and different.
Turbo flutter vs blow off valve comes down to understanding sound versus function
Turbo flutter is the sharp “flutter” noise you sometimes hear after lifting off the throttle in a turbocharged.
In actual fact, no bov makes the compressor surge fluttering sound, the noise actually comes from the turbo
This certain “sequential” bov however is often responsible for causing compressor surge, which.
