should i swap a greddy bov?

[darthvadar tsi]

Hey tuners! just wanted to know your opinions on if i should swap out a greddy type s with a 1g bov its a vented bov so id like to hear the valve blow off a little louder+ im recirculated . it can hold a lot more boost but let me get your guys opinions!

 

[Juanpa]

You can't go wrong with the type S.

And the type S is already loud. If you want any louder go with a RFL BOV. Haha

its not loud on mine but im only running 10 psi, well i already have the 1g bov so i dont think im gonna buy another

If the Greddy does not leak keep it. I didn't quite grasp what you were saying but stay recirculated unless you have a GM MAF in blow through or are running speed density. The Greddy and 1g BOV are both recirculating BOVs.

nope doesnt leak one bit, id rather stay recirculated than get a maft its a lot better for the car

Yes it is better to stay recirculated which is what I was getting at.

So what is it that you are trying to figure out then? You have a non leaking BOV that holds more boost and is able to be recirculated which your current setup requires.


Please use your shift key, thanks.

Well i don't have any problems but id like to hear the bov more that's why i wanted to swap
to a 1g because i heard it was a louder valve. i dont want to buy another like the turbo xs

thats why im talking about just the 1g and greddy

If the valve works then keep it. Function>"style", why swap out a perfectly working BOV to impress others? In all honest, I wish my BOV was recirculated when I had the Greddy as it was too loud and annoying. It was 'neat' the first few blow offs but after that it got annoying. Switched to a TiAL Q, much much quieter and I'm happy.

But again, if it works then keep it, don't be concerned about the sound.

 

[ilco187]

Well dont get a type s cause i have one and it leaks, i have a friend who has one on his sti and his leaks too. so i dont see them as being a good bov.

that was an awesome answer, your totally right im gonna stick with the greddy on there thanks bro

its already on my car ha its worked good for me so far, maybe the subarus and greddy parts dont get along?

I just purchased the type s BOV should expect it by Friday, I currently have my HKS ssqv2 limited edition bov with original fitting, my stock plastic bov sucked ass and leaked so I went ahead and bought the SSQV and a recirculation adapter as well, since I want to stay recirculated, but the adapter did not fit, it was a HKS real adapter, but I went ahead check HKS.com and just found out that my HKS Ssqv is fake very convincing box/sticker/logo everything you name it.

But it works fine, I love the sequential bov and it's nice soft to high pitch sound that makes heads turn everywhere and sti's & evos wonder WTF is going on?! Lol

But I can't recirculate it at all luckily my Gst is one of those cars that show lil symptoms and don't run like shit except the fact that every time I let off the gas at boost the car eats gas faster like I eat tacos or drink beer. And we all know it's not good for the 4g63 going from lean and rich in an instant moment, it also stalls out if you below 2k Rpms and try to build boost but have to break for a light or for anything at all!!!

And I would go back to my oem bov but I broke the lil nipple that connects to the hose!

I was shooting for a ngr type s bov but said WTF why not just buy a real GReddy bov, I was thinking of going for the type rs but I knew I needed a Greddy recirculation fitting, so I settled for the type s except one little speed bump, I still need that god dam recirculating adapter hahaha

Ninja edit:
Sorry I know too much info and like who cares about my life right

I know this thread is about a BOV but I will add my 2 cents.

After running a GM MAF in blow through I will never ever run a stock MAF before the turbo.

Removing the MAF from the Inlet of the turbo makes a huge difference in the response of the turbo. It spool's a little sooner and also spools faster.

you can still recirculate the BOV if you want.

Just my experience!!

you lost me there for a sec about the GM MAF?....

GM as in GM motors?...

Correct.

You use a General motors MAF and then use the correct MAFT(translator)

It has its pros and its cons but if you know how to work with it its great.

FULL THROTTLE SPEED - MAF TRANSLATOR FOR 2G ECLIPSE AND 3S

Thats the translator.

 

[untouchablecc]

He is talking about the proper way to run your open bov open so you can hear it.
There are hundreds of posts on this you can find in the search feature.

I do agree with the previous post about the turbo spooling better with gm maf and its the best way to run an open bov or using speed density. You want to be able to hear you bov well those are your options. Switching to a 1g bov might be a lil louder but not by much because its muffled by that rubber hose.

If you have the ricer itch like myself to hear your blow off valve because you think its bad ass you will eventually run a different mass air for that reason but many others like better tuning capability. I run GM mass right now but i wanna run speed density. Mass is just cheaper though because you can go junk yarding and get 10 of the mass airs for like 50 bucks. I used dsmlink so i dont need a maf translator.

One thing i wanted to add about leaking bovs. The stock bov will leak around 18lbs on a 1g unless you modify it. The greddy bov seems to leak around 20-25lbs typically. Blitz leak whenever. Turbo xs leak. The only bovs i know that hold higher boost for a fact are Tial and HKS if anyone has more info on this feel free to add. These are just my experiences with the valves because i have used all of these.

 

[nightmares GS-T]

The 1g bov is great and if you get to boost levels where it does leak all you have to do is crush it and it wont leak.

 

[ilco187]

I was shooting for a ngr type s bov but said WTF why not just buy a real GReddy bov,

The ngr is better than the original type s as its diaphragm is stronger, thats about the only difference.

 

[dmentdgst]

I have a greddy type s with an ngr diaphragm, I did not put it in, previous guy did, said it hold pretty well until about 25psi, I don't know if it does, as I only have it set for 16psi, but when I do blt I always do them at 20psi and no leaks whatsoever

 

[TSI_AWD_FTW]

I just want to say this, I've been threw plenty of BOVs trying to find one I liked. By far the crushed 1g is the best BOV I've used. Second favorite was the RFL BOV, just cause I liked snappin necks. haha

 

[gusu]

The intensity of sound from your BOV depends on a few things. Intake, hard piping, how close it is to the throttle body, boost pressure when it opens and of course you know about when you run vented vs unvented.

I personally like the blow off sound but I think the greddy sounds terrible. I'd prefer a SSQV if I was going to be a ton of boost to get that cool mutli-stage blow off sound but the TiAL sounds great all the time. The SSQV just sounds more unique but the TiAL has hat race car sound to it

cool bro im only at 10pounds and i do need a cone filter im running just regular k and n filter. i dont have hard intercooler piping and need to go bigger to 2.5 i think after i do those things it should be some sound?

 

[Bullet3]

Has anyone used an evo 8 bov? I've read it is holds up to 28psi without leaks. Can be obtained a lot cheaper then most aftermarket bov's, and of course is recirc.
