Blow Off Valve Thread.....

[USDM_OneVia]

I am going to buy a blow off valve tomorrow and I just wanted everyone's opinion on the following one's, pro's and con's. These are the 2 that I am leaning towards....

GReddy Type S--------------------

-Can be recirced-Great Sounding-Will eventually match all my GReddy Crap

HKS SSQV--------------Can also be recirced-Sound can take some getting used to-Looks Great-But everyone has them...

Which one's do you guys run and why? Also, which do you prefer and why?

I am going to buy a full kit, with BOV, Flange, and hotpipe, so my 5 week old GReddy hotpipe will be available very shortly. Probably in the neighborhood of 75 bucks. I just wanted to get a nice hotpipe until I decided what BOV to run when my FMIC came in, so I bought that one from Enjuku for 115 shipped. Looks fantastic, and actually fits a CA. Sits a bit high on the turbo side, but will NOT hit the hood. Email or post if interested.

I don't like the newer SSQV's, the sound isn't right for me.I got twin HKS super's.

what ever you do dont buy a turbo XS BOV!!!!!!

so hows she running? , i almost got this other CA runing and driveable but soon as tahts happening its gettin shipped away so i ll be with out the fun turbo 240 for the next few monthes, you should let me come down and take yours for a spin some day when i have a day off and free

[iliketocrash]

the type s leaks! alot! my friend had one on his talon for about 2 months and the slut just started leaking like crazy. i've also heard about other ones leaking but this is the only first hand encounter i've had.

I really liked your turbo XS one, sound was great on it. But Robin said that sometimes it wouldn't blow off, or would blow off for no reason whatsoever.

I am thinking of just going with the HKS one and getting the lower pitched insert for it to make it sound less like a donkey being flogged to death.

Oh... BTW, I am off Wednesdays and Thursdays. Come on down or gimme a call anytime. I want to buy those tear drops off of you! I tried calling last week, but I guess you were at work. IM me sometime bro! Haven't talked to ya in forever man.

not that you seemed interested, but i am quite impressed with my apexi twin chamber bov. doesnt act up and holds like fort knox until you let off the gas. i would highly reccomend it and on the plus side, it is one of the cheapest at about 170 bucks (i think..).

I got a 1G DSM bov, probably the cheapest route you can goand i find it pretty loud when vented to the atmosphere

[Nismo1182]

Im running a 1G DSM BOV too. Its nice sounding and gets the job done.

[float_6969]

I love my HKS SSQV. No complaints here, and if I decide to recirculate it it's not hassle to do so.

joe. yaeh im off thurs but im feeling like crap! plus i think my boss just caught what i have so i think ill end up workin for him thurs, also i changed cell numbers.. my new one is 937-554-5072. im never online before like 330am. hell im never awake before 2pm, night life is gettin awfully boring.

so are we still trading wheels??? i need to get free time soon or im goin to go farther into insanity...

[sil80drifter]

What about those cheap e-bay dealies that look kind of like the XS BOVs? The reasoning here is that you can't really go wong when machinig a BOV and so their cheapness on e-bay may be just a result of mass production/ease of manufacturing, rather than poor quality. And I know, I know u get what u pay for. But they are 50-80 bucks (depending on what "stage" you get.), and they look solid. Yes, the people who sell them look like a bunch of ricers, but come on, the crowd they have to appeal to is...well you know who they have to appeal to.

If you still want them, they are yours bro. The wife is still rockin' them on the fastback so they aren't going anywhere. We can trade them, or I can just give you cash for the teardrops, up to you bro.

i have the RFL and i love it...

[SHIEF]

Hmmm...I realy like the Apexi bov and a few maps (besides SCC) I've seen but have never heard it in person. I'm wondering how it sounds. Is it louder then the Greddy S? Also the Blitz DD, because it sounds like no other bov, and also has a good map to it. Those are my top 2.

[andrave]

apexi twin chamber is like deeper "psshh", kind of like a truck letting off air. its more the traditional deep bov sound. Its moderate to loud.

greddy type S is a higher pitched "psscchhheee" and it sounds higher in pitch than the "traditional" bov sound. It is pretty loud.

hks SSQV is like "squeeeaaaa" and its pretty funky, althought I don't know what inserts or anything were in the ones I heard. It gets higher pitched and louder the more boost you run... if you hear it on a low boost car it isn't as squeaky but it still doesn't sound good, but it isn't as loud. once you get some boost flowing through it gets louder.

the RFL is a really loud "psshhh," about medium in pitch, and loud as hell. I heard one on a mostly stock WRX and its the loudest one I've ever heard.

the blitz ( I think super sound?) I only heard once, on an 93 twin turbo RX-7, and it was pretty deep in pitch, moderate loudness, and had a longer, lower "swooosh" to it.

These are all compared to the "standard" 1st gen dsm bypass valve run to atmosphere.

[alfred183]

SSQV sounds like you're running over mice

[boost_boy]

I use the old school blitz supersound coupled with a Greddy Type R and the release unreal. The way those puppies let off 20 lbs of boost and an open Hks wastegate dumping is just scary-fying to joggers in my neighborhood:D The pair actually work very well together because I use the blitz on the turbo side and the type R on the throttle body side. I have this set up for both my sentras as well.

[SHIEF]

If you watch that one movie with the R34, S15, RX-7, and the Supra, the Supra has the Blitz bov and it sounds nice. I'll prob go with the Blitz but that messes up my almost all Apexi appeal. Oh well, I'm such a girl.

[sil80drifter]

nobody comments on ebay BOVs... they are cheap guys, and they may work just as well... all a BOV is is a vacum activated spring-resistant cylinder. The sounds... well you can put a little flare on any BOV to change its sound, why pay hundreds of dollars more?

sil80

[andrave]

it thats how you feel then get a DSM or something, why even bother spending 50 on an ebay piece of crap?

[sil80drifter]

Well, DSM BOV costs only 20 bucks, but it's plastic and I can't weld it onto my pipes. And AGAIN how do you know ebay ones are crap? Have you tried them? Do you know anyone who has?If so, why haven't you spoken up when I asked about it?Don't state things you don't have proof behind.

sil80

[r34 gtr]

whoa! easy there killer! haha. anyway, my friend has the blitz dd bov on his civic and it is a lower whoosh sound. my apexi lets people know im coming, which can kinda be bad sometimes. you can however change its sound by turning the ring-o-holes on the body of it. goes from really loud psssshhhtt to a sort of low wheeze depending on how its set.

[Nismo1182]

Whoa there, 1G DSM BOV are metal. 2G are the useless plastic ones.

I have 2 here for sale if anyone want them.

[moomoomoo]

my friend picked up an ebay bov and he said it suckshis stock plastic 2g talon bov was louder and it was recirculated too

[sil80drifter]

Ok, at least that's one opinion. Did he say why it sucked? I want to know if he didn't like the sound or it was bad at blowing off excess air. Recirculation should probably not be a criteria, because everyone wants different ones, and whether u can or cannot recirculate it is not a "problem" it's just a type. Sorry I forgot that 1G BOVs were metal.

sil80

[Nismo1182]

Recirculation can be a problem. Once the BOV vents off that air and say your coming to a stop light, the car will drop to a very low idle or even stall.

[sil80drifter]

You can compensate for it. The point being that people can run either or and if they are looking for a recirculating BOV then they get one, I for example am not, so I don't consider it a problem.Recirculation/non-recirculation is a preference, not a fault. If you don't tune for non-recirculation, then you may have problems. That goes for most things though.

sil80

[moomoomoo]

his reason for it sucking was based on sound

[sil80drifter]

Oh sorry, I didn't read into that Talon comparison.Ok, so the ebay BOV isn't too loud. I don't think that makes it a bad BOV, just not a loud one. If someone wants a loud one, I guess it's not the BOV for them. But does it get the job done, is what I'm more concerned with. So far we've discussed BOVs in terms of whether they are decent at blowing off excess air. Like the XS BOV isn't great because it leaks and seems to have trouble knowing when to blow off. I've heard this opinion from other people as well, and I've also heard it in action, and it's VERY loud. This doesn't make it a good BOV, just a loud one.

Can you ask your friend if he had any performance related issues with the ebay BOV, that do not concern the volume it functions at?
