Best Plumb-back B.o.v.

[Spunky Munky]

Hey fellas,

As most of us know, R33's stall as hell when there's a atmospheric installed - it plays with the airflow meter, mixtures and ecu settings etc which caused really bad stalling issues... I've put back my stock BOV, but I miss the nice pod-suction sound heaps and also the Sshhhhttt sound - driving a turbo without this sound really is a bit of a let-down.

I've heard though, if I get a BOV which has 2 sides - one that plumbs back and the other that vents out - I'll still satisfy the requirements of the car and will also get the nice blow-off sound.

Which ones would do the above - any suggestions, fellas?

Thanks in advance.

get your std bov modified to take more and make more sound.

GFB Hybrid bov does exactly what you asked for.

I've got one, but ive got mine plumbed back entirely. I dont like the pssshht lol. I used to have it 50/50 plumbed and atmo. The car stalled a few times over months it was like this, usually under hard braking.

I love the pppssshhhhtttt sound. lol

I hate it when the car stalls if full atmo, so I'll go 50/50 then... yeah, was also thinking of the GFB Stealth FX BOV... sounds nice and also heard some times it doesn't stall on R33's... what can you do though.. ha ha ha

Thanks.

I wonder why everyone's going back to stock - is there a reason for this?

Just keep the stock man, you can't go wrong!

I used a SSQ for like 10 minutes, then blocked the stock BOV off..

1 week later and I unblocked it all and had it running normal.. you don't realize how smooth and nice it runs with the stock plumb back setup until you change it

The stalling, lag between gears, its just annoying.

My opinion anyways.

Wow, thanks for the heads up mate... but I love the Ssshhhtttt sound... damn it... really love that sound... but I know what you mean buddy.... I know perfectly what you're referring to... stock does make the car run much smoother - not to mention no more stalling which is a pain in the arse... thanks mate...

If done right, would the GFB work just as well if no lag?

Cheers,

might be a stupid question, but how do u set the gfb bovs to be full plumbback?

do u just turn the screw all the way in or what? ive got all the return piping etc connected

[jeffworld2]

any bov will not stall if you tighten it up a lot. my line was imported with hks ssqv and never stalled. about 6 months in everyone i knew was getting pulled over so i changed to an r34 gtt bov, which is the same as a gtst, and can still hear turbo noises to make me love driving the car, but dont have to worry about getting into trouble lol. its a stupid thing to be defected for, especially when the original equipment is so good

[R34NRG]

the only reason ur car stalls wen its at full atmo is because u havnt tuned it to have a fulla tmo BOV. i run a atmo bov all day every day and it never stalls ever.

[(B1) MR_fanny]

i guess if you really like the sound then in the end its your call. i drove a rex with one and after a day of driving i was over the sound..ha. negatives outweigh the positives in my books so i stuck with the stocker. i still get the pshh sound with my arc box, just not as loud though.

[TaKz]

i was wondering if u do get something like gfb stealth fx and tune it for full atmo

and sometimes you decide to adjust it so its full plumbback how this would affect the car?

if u did this, when the car was running a full plumb back when its tuned for atmo, ud be running your engine really lean and could cause engine damage.

And how exactly do you tune a car with an AFM to run an atmo BOV?

[QWK32]

And how exactly do you tune a car with an AFM to run an atmo BOV?

with an safc, the DecAir settings. on a full aftermakert ecu with a deceleration enrichment/enleanment correction map (what its called can vary from ecu to ecu).

[sleek3]

i run a gfb fx which is fully adjustable and i run it 1/4 so i still get the sound but without the stalling

Yeah I know what you mean... is the 'original' stuff that good? sounds good... I gotta say, the stock one doesn't stall is that's a first...

But I really miss the nice tough suction sound and the ssshhhtttt let off sound.... how the heck can I modify the original to give off more sound whilst not stalling the damn car?

I heard blocking the hole spools up faster but will crash the car.

I'm going to install a emanage - do you think the BOV can be tuned to work fine without no more stalling?

Thanks.

You're taking the piss yeh?

[stolen_s15]

^^ Nah he's serious, have a read of his other threads. *shakes head*

Thien, you cant get the sound of venting to atmosphere without the problems that come along with it, unless you change over to an ecu that does not use an AFM.

[r33cruiser]

ive had no probs with my vta hks ssq.

stock ecu and management.

it actually has increased response.

lol and for some reason i gained 0.3hp (yay).

so apart from the pssscchhhhttt sound man. there is no real benefit of going vta. just means when u accellerate u get that at times unwanted effect and the attention that comes with it.

im sure there has to be atleast 1 1000hp+ car out there that runs a plumb back bov... surely?
