Apex'i BOV
I installed an Apex'i BOV on my FD last night, I set it to the large hole in the disc on the bottom, but it still wasn't that loud. with the windows up I could barely hear it over the RP exhaust. It was raining so I couldn't try it with the windows down. My stock BOV (disconnected from the factory airbox) seemed louder under boost. My car runs 10psi, and I can't figure it out. I was expecting it to be much louder than stock. I guess when I read "louder than stock" I was thinking about the stock BOV discharging in the atmosphere. Maybe they meant louder than stock with it still connected. Any idea's?

I do agree with you on that one, wargasm, to each his own. I am pleased with the apex'i function, as I have been researching BOV's for some time now, just wanted to make it sound how I like.

No, sound isn't the most important thing, but would you rather have a nice sound or something that sounds like it came off a semi? Presentation is everything, being able to back it up is next.

As for the Apex'i BOV, it's not a really loud BOV. If that's what you were looking for, you bought the wrong one. It retains the "whoosh" sound, but that's about it. I do think it's better than venting the stock BOV as the spring doens't vent under vacuum like the stock BOV. The largest opening is the loudest setting.
Make sure you don't have any other problems, like boost leaking, as it should be just as loud if not louder than the stock BOV vented.

If it's the sound that makes you happy then "to each his own". That's pretty ironic, huh?
I like the way blow off valves sound, so what. I am sure those that buy exhaust systems are also concerned about the way they sound. I don't see anybody jumping down throats questioning the sound of an exhaust.
I have the Apex-I blow-off valve and like it because of its conservative nature. I don't like the ones that scream like a wild banshee. That is only because they can get too loud for comfort, kind of akin to a loud exhaust. Wouldn't you say?
Don't label me because of my preference and interest please.

Makes no sense.
If there are 3 or 4 engineers standing in a room preparing to design a blow off valve I would rather they focus their energy on the sealing properties, the pressure relief mechanism, the repeatability of its action and the overall quality of its construction.
I simply can't imagine spending any time tuning the thing for sound. Purchasing a BOV by what sounds it makes is akin to purchasing tires because they make more smoke and better looking burnout marks than another brand.
It baffles me. I clicked the thread because I thought there may be rational discussion about different brands of BOV. I may purchase one soon and I have absolutely no interest if it makes a fart noise as long as it was engineered correctly and works as promised.

I tried all the holes last night running up and down the street, and I think the biggest hole sounds louder. I like the sound and I think I'll stick with Apex, rather than blitz. Plus Blitz is pricier. Plus I've already bought the Apex'i.

if you want something to be heard check out turbo xs rfl...substantially loud

probably only going to be using it for 10-15 psi, if this info matters.
Thanks!

btw. I emailed them about a FD adapter, and the response was:
"Actually, the H-Supra kit will let you intall a BOV-H or BOV-H-RFL to the 93-95 RX7."
Or should i start a new thread regarding the TurboXS BOV performance?

To address the question at hand, the Apex'i does not sound like a typical aftermarket BOV. It is more subdued. But you picked a damn good and effect BOV. The sound will grow on you and you will appreciate the volume of it in time.
