Which BOV is this?

[95TalonOwner]

Ok, so i was cruising around one night at the local cruising strip and there are these 2 Grand Nationals that are up there a lot. When they blow off it sounds like.....WooooooWooooooWoooooWoooooWooooo......(it kind of sounds like the 3 stooges). I have also had one talon pull up next to me one day and it had the same BOV.

I have had no luck trying to find a BOV that sounded like this and have no clue what brand or anything. Does anyone now what I am talking about?

A bov that i have heard that sounds like that is the HKS, but just about any aftermarket blow off valve that vents to the atmosphere will make that kind of sound if you have a big ass turbo because the turbo keeps sending pressure through the intercooler lines and the bov keeps venting until the turbo spools down.

Ok thanks for the info, but this one sounded different.

It's a BOV with the spring too loose so it flutters. Terrible for the turbo.

well, to me it seems like Blitz or Megan Racing.
They both have similar design and similar sound coming from the bov.
once the blow off opens, it makes 3-4 pssssshhhh sounds.
it is not loose spring (which also can make that sound).

HKS is more of a high pitch sound.
something like the galaxy game (that airplane shooting sound..)

My Greddy Type-S will flutter at low boost sometimes like 2-3x. It's like a chuu-chuu-chuuuuuuuuu sound, .

Are you sure it was a bov and not compressor surge? I have seen some GN's that have no bov or cbv so the noises that come from them are a little different sometimes. And the sound you describe reminds me of compressor surge on my 60-1 when I had a turbo xs bov.
