Standard BOV

[Sime]

Hi everyone

I originally had a standard BOV on my R33 which had been welded up to give that flutter sound, so I went and bought another standard one thinking it would be nice and quiet but found it makes the typical pshhh noise I'd expect from an aftermarket one. Is this normal? I'm running 12psi of boost so perhaps that causes it to be make more noise. I've also checked to make sure all hoses are secure and not leaking.

Also when I took the old one off, there was a metal plate in between the BOV and the air intake pipe it attaches to. This has a hole in it smaller than the opening on the BOV and causes a slight flutter noise and a slight pshhh. Is this supposed to be there or did the previous owner put it there, perhaps to run higher boost than the standard BOV can cope with?

My standard Blow Off Vavle copes with 17Psi. Are you sure that the plumb back pipe is connected?

It's definately connected, I take it it's not supposed to make much noise

mine made a fair noise, not as loud as my new gfb hybrid, but with the pod filter it could be easitly heard and once the fmic was on it started fluttering too

Ahhh! I have a pod filter also so that maybe why. What about the metal plate. Is that supposed to be there?

hey mate, i just changed my BOV, that metal plate is a gasket. And as said above the swoosh that u are hearing is your pod, if you had your old air box put back in you would hear nothing.
