Plugging blow-off valves?
hello all, this is somewhat of a controversial topic, but I wanted to know people's opinions about plugging the BOV/DV to get the famous/infamous turbo flutter. I already have my own opinions on the matter, but I'm just curious as to what other people on this forum have to say on the topic.

When it came to the BOV on my subie, lots of people thought you had to install a different BOV to make a loud PSSSSSSHHHH sound, but the reason you don't hear it is because if the intake silencing. Put a short-ram intake on there and it's loud as can be, you hear it all the time. Heavier duty BOVs are needed when you put a bigger turbo in there.

My b58 has no BOV.

X2 m35i has a bov but regular b46/48 doesn’t. I am guessing it’s dependent on the boost running. 14psi, ok, 23, no.
