im thinking its a Blitz BOV. correct me if you think i am wrong.

i like the sound of it!

 

i'd have to agree with ya JoeD. its definately not an HKS...Greddy...or Apexi. if i had to guess i'd go with Blitz. i actually just listened to a sound clip of almost every BOV on the market so i kinda cheated

 

Where can I get wav files of the blow off valves, specifically the Apex (since I'm kinda have to get one) - thanks!

 

Is that a rotary engine... sounds like a motor bike near the end of the clip. Could that BOV be a stock vented away from the stock box? jc.

 

how did you do that, i want to hear them, do you have the files?

here is a video of a 300XZ running Apex'i BOVs. they sound cool, but i have heard they are shitty units.

The apexi unit is a piece of ****. By far the worse bov i ever bought for my car. I had three: greddy bov type s, apexi, and hks ssqv bov. THe best working unit was the hks and that sounded sweet. The greddy was loud as hell and best sounding but did not work as good as the hks. Apexi was just ****. So if i was gonna buy one, get the hks ssqv bov. I dont have one on my fd yet but this is experience with my supra when i had it. I heard blitz was good too though.
