Blow Off Valves

[Xizor]

hahaha ok

Ok so i dont really care about flutter, a little flutter wouldnt bother me but thats not what im after, i just want a tighter, bit more aggressive bov sound. So suits the car better. Im sick of the simple woosh of the stock one. I want it to have a little punch. But nothing TOO crazy.

Greddy plumb back or SSQV?

jeff i dont have the slightest what your on about with most of that

[jeffworld2]

lol

there is a diy/tutorial on how to tighten the stock bov. you put a screw in one of the holes, but i never really looked into it. if you want it to go off tighter, thats exactly what you have to do; tighten it up. if all the air goes through quicker it will have to be more forceful and louder i guess.

Gtr ones do fit, but they may not be much different. i'm running a BOV from an r34, but my airbox is damped so i dont get much noise (plus exhaust is too loud)

[Xizor]

I thought that was for the hobos that want to force the flutter noise? thats not really what im lookin for

[jeffworld2]

it only flutters if you lift off to make it flutter in that situation, used to do it in my hks one, a light lift off and reapplication on the freeway and chuchuchu.. a normal gearchange and tss. a flutter occurs when the pressure let off is not enough to pop the spring in the bov, so air chugs through the compressor

I have the GFB Stealth FX

When it is on plumb back mode it is far louder and deeper sounding than the stock BOV was...but that difference may come from the fact that I was running 12psi with the stock one and now I am running 22psi so it is actually passing alot more air?

[Xizor]

Interesting Bunta. Im running 12psi, i havent really noticed that much difference in bov noice now compared to when i was running stock. But 22psi is alot more

Is the GFB Stealth FX and dual atmo/plumb back bov?

[jeffworld2]

yea rob thats the type you can switch i was saying for the extra one

[markimak]

my SSQ that came with my old GTiR did the chu chu chu sound.. but stock BOVs for all my cars now.. say no to leaks!..

also if u dnt run AFM.. unplug ur stanard return piping.. thats loud enough if that gets u off

[Xizor]

Jeffworld2 and i played around with some things using my stock bov and we had it fluttering and all that, but as i said before, i dont care about flutter. Infact i'd prefer to have none now after experiencing it first hand. It's simply gay. What i want is just a normal blow off noise but instead of a loose wooshy sound i have now, a more punchier kinda sound. Follow?

instead of having the a/m one switch to plumb-back or atmo, totally block the polumback one and you will have no issues. if you want flutters, just put a blanking plate on the stocker your pod will do the rest.

Good way to make your car stall when you pull up at the lights

[aDrew_C]

So the GTR one is not plumb back by default? Is it easy to do?

Yeah they are plumback, but my RB25 was made to be atmo for no reason... so I'd need some pipe and a t piece adaptor or whatever to set it up plumback, if you're replace a stock rb25 plumbed back bov, it will attach just fine afaik.

[jeffworld2]

how exactly? it would be the same as running no bov, it will not make a sound (will flutter through pod, but no woosh) and cannot cause any issues other than perhaps overfuelling on gear changes as air flutters out through the afm instead of being recirculated. only when the valve is opened to atmo will you get a woosh.

i had an hks ssqv on my 33 since it was delivered from japan, never had a stalling issue. its all about setup and the spring strength. i have since run without bov at all for a week and now run stock BOV from an R34GTT, but its the same part really as stock 33.

if you don't understand what i was trying to explain in that post, don't reply, or if you do reply like XIZOR did

jeff i dont have the slightest what your on about with most of that

any aftermarket plumb back (that can be adjusted) will be what your after. Turbosmart, greddy etc etc
