I'm and idiot and put a Blitz SS BOV on my SR

[nrcooled]

And since I am a huge idiot I need to buy another BOV. It's leaking pretty bad at full boost. To the point that the car stutters under full boost (thought it was plugs at first). Also the dam_n thing stalls all the time. I am going to just tighten the spring more but from what I hear it only works so well. So now I need to get a new BOV.

So I don't make the same mistake what BOV work best for the MAF and SR.

I know the HKS SSQV is one of the best just want to know if there are any others that are just as good ::reliable:::confused:


I SUCK FOR NOT LISTENING TO FOXCOLT!!!!!!

[Yoshi]

I have a GReddy type S BOV, no probs so far, it's all bling blling lookin too hahahaha. I love GReddy

Yeah, I'm the lucky owner of Jed's old Blitz. :o I'm tired of it leaking at idle, so I'm currently awaiting a second flange from Wayne at Phase2. He said you can just take off the horn, put the flange there, and then use a hose to recirc the BOV. I'm sure it will still make a fair amount of noise, and it won't matter if it leaks at idle. I'm looking forward to it.

$25 shipped.

yeah I too have been wondering what bov's are "safe" for use with turbo'ed cars.
I am getting the CA18det and I can't afford to spend money on mistakes that will make my car not idle and stuff.

[thon]

I use a prof sheepdog BOV, no leaking ever. its awsome.

Planb from FA uses a sard r2d2 and he's happy with that one.

Why WOULDN'T you want the HKS if you already knew it was considered the best by SR owners for atmosperic use?

Because Jed had this one for sale with the pipe for $100 shipped :D

I have the GReddy type-S.... really like it, idles like a champ and sounds pretty good to boot

[Maeda]

the SSQV uses a special system of 2 valves(?) so air cant leak out, hence the name sequential...

i THINK this design is unique to HKS valves...
Apexi also makes one with dual chamber design? i have no clue if this is similar...

i'm am also the new proud owner of one... =D

gotta love that venting pressure sound as opposed to the woosh of most bovs =D

[HaLo]

I have an apex-i dual chamber bov. The car stalls...it's normal. An atmospheric bov will do that. You maf takes air flow reading that never get in the engine when the air is release by the bov. Result: engine runs rich for a fraction of a second.

[Fastback180]

I have an HKS SSQV sticker on my helmet. :cool:

[Foxcolt]

lol...I told you Bakari!!

This is the one you want!!! (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2409738312&category=33742)


it's a diaphram type. Those won't leak at idle. I believe the greddy is much the same. Most if not all piston type bov's will leak at idle and if you don't have the spring tightned all the way will leak at full boost.

Consider yourself lucky...At least your making boost!!
I'm currently driving the equivelent of an sr20de on nitrous:p

[uiuc240]

yeah, that would be a nice upgrade...but i'm just going to recirculate mine and be done with it. if it's recirculating, it shouldn't matter if it leaks, right? or am i retarded about that too?

you'll be fine with it recirculating. I met a guy w/ a recirculating greddy on his s13sr and it sounded great! Kinda made me think twice about my quest for the ultimate atomopheric bov..lol

Either way just make sure your not leaking under full throttle and you'll be good to go.

Also with the blitz piston type. Depending on how much blow by you have it might help if you take that bov and clean it out. Take it apart and regrease the piston. Real easy to take apart, there's just a c clip holding the piston in the chamber.

[nrcooled]

I am an idiot and bought it cause it was cheap and available ASAP. I just wanted to get my FMIC on.

Anyway yesterday my friend w/ a Z28 wanted to go for a run. After I "stuttered" again in fourth gear I realized that I am shooting to 18psi and it was my fuel cut that was causing it. My guess is that the leaky BOV is causing my overshooting So if anyone is keeping score I need:
1. BOV that doesn't suck
2. Tires for my new rims
3. Adjustable actuator (to stop overshooting)


This is going to get expensive:(


Edit: to tighten the spring on the Blitz it's just "righty tighty lefty loosey" correct? Also is there such thing as over tightening it. It alredy sucks but I also don't want to break the stupid thing so I can at least sell it to a Honda guy

[uiuc240]

yeah, i'm looking forward to recirculating it and loosening up the valve. right now, i have it really tight because it leaks at part throttle a little bit (and at idle). but the first night i had it in, i had it really loose and it sounded SO cool. no flutter, just a big WOOSH! i miss that. hope to get it back with the recirc "kit"

Do you just plumb it back to the intake w/ the adapter that your buying? I am curious how the recirc. adapter looks and works:confused:

[uiuc240]

yeah, i'll be taking off the "horn" and putting another BOV flange in it's place. then from that flange, i'll connect a hose and route that back to the same place on the intake the stock valve recirculates to. it should still be loud enough.

Eric

[Foxcolt]

You can't over tighten it. You'll just end up tightening it until it gets completly shut. That's when you get the horse sound :D

Here's what I recommend. BOV's hold there value pretty well. If you have the money order the hks one and stick that blitz up on ebay. You should get what you paid for it.
If you don't have the money just run without a bov for a bit. Sell the blitz and buy the hks. It won't hurt anything. Just don't make too many full throttle passes just to be on the safe side.

[uiuc240]

well, before i do that, i'm going to try the recirculating trick for a while and see if i like how it sounds and operates. i'll be sure to tell people here so they can decide for themselves.

or were you talking to Bakari, Jed?

Yeah I was talking to Bakari:D

When do you expect that flange in? Might be better for him to hear your results before taking any action.

I was thinking that myself since its cheaper than getting another BOV and less trouble.

Eric,
Do you use a boost controller? Are you having issues holding boost? Man this sucks. The FMIC has definately added power I just can't use it for fear of overshooting and detonating. Thank God for the fuel cut to keep me from blowing up my engine last night

[Foxcolt]

Bakari if you think it's your actuator that's busted and causing you to over shoot, I'm more than willing to let you try my stock one out. I know it's good and it's a cinch to bolt on.

[nrcooled]

i think its my boost controller that is not closing off at full boost and just letting the actuator stay open. I am thinking since the BOV is leaking at full boost it is bleeding off some of the pressure that my BC is looking for hence not closing properly.


It very well maybe my actuator but it worked beautifully before I started upgrading. Once It stops raining I will start taking stuff apart and inspecting. For now I am just going to tighten the BOV down:rolleyes:

That would'nt cause you to overshoot though. It would cause you not to make boost.

More than likley you just need to tune your boost controller. I swear it took me month's to tune mine to the point where I felt happy with it.

Jed's right. If the BOV is bleeding boost, you wouldn't have seen the pressure shoot up in the first place. Which controller are you using? AVC-R? Profec B? Can you turn up the duty cycle?

I don't have a controller yet. Debating on whether or not to get one. From what Jed is saying, I think I'm going to just keep it simple and get an adjustable HKS wastegate. That will hold all the boost I want (12-15 psi) and will work just fine with my S14 T28.

As for your bleeding boost theory, you could try removing the BOV entirely. Put the old metal pipe back in your hotpipe (do you still have that part of the setup?) and run it a few times with no BOV. You won't kill the turbo. Trust me, I've had chatter/blow-off for almost the whole time I've had the SR...turbo is fine.

Wow, if you don't have the skills or the brain power to get the Blits dd BOV to work then leave it to someone who knows what they are doing. LOL

[TokyoNights]

i have the blitz super sound on my sr and its fine ,,doesnt even stall:confused: but i havent really drove the car too much since i still got a stock fuel pump..

If you don't have the brainpower to look at dates then I think you should stfu.

When you search don't reply to threads with a pointless comment.

KiDyNomiTe: 1, ace240sx: 0

Seriously, you revived a dead thread to talk trash about someone? How lame are you?

[95zilvia]

Oh well, since someone bought it up anyways... hehe
I really want a fluttering sound for my BOV, u know, like the JDM drifters...
it makes that tsu tssu tsuuuu sound
Some cars that make the sound are the Champ s14 and the uhm... that nice s15...
i currently have the blitz SS bov... i dont really like it when it makes the WHOOSH...
what goes about in making ur bov recirculate, or whatever...
and when it recirculates, is that when it makes the fluttering sound?
teach me!

[ace240sx]

Actually if your Blitz BOV is mounted on the hot side of the I/C piping then you can take the filter flange fitting and cut the filter off. Then interchange the horn for the cut filter you just made. Take some coolant hose to connect to the end of the cut flange and to the stock metal pipe that is sticking out of the OEM sr20det rubber air intake. This is an easy way to make the Blitz BOV into a recurculating valve. :)


Future Plans: Reprograming the sr20det sequential eprom stored fuel maps. (Why pay over $500?? when it really costs $25??)

[srpowereds14]

95 zilvia.... the JDM drifters DONT USE BOV"S that sound is the the air goin back towards the turbine propelers causing it to make the fluttering sound... mine was like that for about 6 months then i decided to put a bov cause i didnt feel like buying turbos like i was buying tires lol!! Signal actually suggested to NOT put a BOV on my car i guess cause theres less turbo lag. wierd

What? If they dont use BOVs then what do they use? :P

Did you mean they dont use ATMOSPHERIC BOV?

Even in that case I'm not so sure thats the case.. I know plenty of JDM people who had atmospheric (but they also had some kind of standalone/piggyback/rom tune to compensate for the BS associated with it)

[Siizzzoooo]

i think running atmospheric is kinda pointless. the only thing you're doing is making your car rich. It throws your MAF off. The longer you do it, the worse it gets.

If its the sound you guys are worried about...as long as you have an open element air filter you can still hear it just as well.

[turboex]

I run a blitz DD, never had a problem with it, no stalls no leaks. hold good to 18psi at leasts.

[Jsquared]

it's a diaphram type. Those won't leak at idle. I believe the greddy is much the same. Most if not all piston type bov's will leak at idle and if you don't have the spring tightned all the way will leak at full boost.
You have it backwards. The GReddy is a piston-type. Diaphragm types are known to leak (torn diaphragm) and not hold up to high boost pressures too well (e.g. stock Porsche BPVs and stock 2G BPVs). And no "most piston types" won't leak at idle, it is all in what the spring is set to and how tight you've set it. And NO BOV ever will leak at full boost unless it's broken. Think about it. How ever many psi are on the BOV trying to push it open from the turbo, you've got nearly the same from the manifold pushing back on the top of the BOV.

RE: the "flutter" sound. BAD. It's called compressor surge, and it will kill a journal-bearing turbo if it's let go for long enough. Unless you have a HKS SSQV, which has two seprate actuations and makes a similar funny sound :D Either way, the flutter means your BOV is too tight. Of course if you loosen it too much it will stay open at idle... which is why I say just recirculate it and leave it loose :D
