In my quest for the perfect BOV as I only plan on purchasing one, here is my list...

Turbo XS-RFL
Blitz DD
Greddy Type-S
Apexi Twin chamber
Ols School Blitz SS
Turbo Smart SuperSonic (Australian brand)
GBC Type III (or something of that nature, made for an Audi/VW)

Budget allowed is about $250. After speakign to Jamesman, he recommend the type-S. Many local Socalers also swears by it.

How come the brass piston BOV are frowned upon?

Any personal experience with any of these listed BOV, I would like to hear about it. By personal experience, i mean you own one, or had one. Not your homie from the team XXX use to run one...:P

thanx.

Better yet, email me with your thought and comments to save space on the board if desired.

i heard the hks type ss last night ona mr2 and it was sweet howz the type s in comparison quieter?

Unless you plan on going over 20psi any time soon, get a 1g BOV. 30-50 dollars. Works just as well (if not better) as those others for 200 dollars less. Use that 200 for some real mods :)

the hks and type s were on the 420a motor, each car sounds different due to different factors... hey jeff, some people would not mind using a 1g bov, but some people kind the cool sound...hehe

I have the old style Blitz Supersound. It's sounds really cool, and it's pretty damn loud, but I had to cut a full coil off the spring to get it to stop having compressor surge. It works fine now though.

I have the TurboXS type S, and i love it. At 10 psi, its pretty darn loud, people always lookin :) At like 0-2 psi, it has a little flutter though, but thats no big deal to me..Holds up to 15 psi they say..

I have the Greddy Type-S bov and I like it alot.

TurboXS Type H... I have pressure tested it and it holds good.

I have the Turbo XS RFL and I like it but it gets annoying sometimes. My homie on the west syde :P had a Greddy type S and I liked it better. (Seriously)

i have the RFL as well. it's fun, because it's so loud, but the sound is very simple, just a loud "<chuff>", or if you ease off the throttle easy it will wistle at you. fun for scaring pedestrians >:-) the first thing i did when i got it was i took it apart, and i was like "crazy, this thing looks like a scientific instrument". it's pretty neat. it looks really cool too, and from what i hear it will handle more boost than any of us 2gnt'ers will be giving it. on the other hand, a lot of 4g63 guys i've seen have been using the greddy (the one with the purple cap? i think this is the type s) and they're usually on top of stuff. lots of people say that the HK$ super-sequental is amazing, but HK$'s stuff is usually overpriced. anyways, i'm done now.

I want the RFL when I get turbo. I have heard it. I don't care. The sound of a super loud BOV never gets old imo. My 2nd choice would be a greddy type s, for the whistle, or maybe hks ssqv. The hks really isn't loud enough to me. The few times I heard a 1st gen BOV, it sounded very similar to the greddy type s, and it would be cheaper.

have you ever heard a 1g BOV vented? Best BOV sound I've ever heard. Nice whoosh of air, followed by a high pitched whistle. I can't wait till I get a VPC :D

Is there a site with sound files of different BOV's?

I like my TuboXS type-H a lot....really loud and sounds great!

damn you Jeff and your 1G!!!! ;)
