question for SR open atmospheric BOV dudes.. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

SR240DET · 02-09-2005, 02:38 AM

why are some of you guys with SR's running open atmospheric BOV on the pull through maf's setup?.........

all the shops told my buddys to run this setup on there cars.... but i cant figure out why some of you are doing it......

So does the loud backfiring. And mine shoots out flames too.

*brndck* · 02-16-2005, 12:34 AM

ok,
#1: flames are cool
#2: loud noises are almost as cool as flames
#3: the only "problem" is running a little rich, which does kinda suck b/c gas is friggin spensive.
btw i'm running a blitz bov and yes they do leak on decel.

s13silady · 02-16-2005, 02:21 AM

ive ran the hks super blow off... then the ssq, then the arc, then the Sard r2d2.
the sard is my super fave...perfect sound (for my taste) doesnt leak, barely any backfire.. just mini pops... and i dont have a cat neither...and my idle is perfect at 850 with no needle bobbing...

97DubTruck · 02-09-2005, 02:33 PM

It doesn't make most sr's studder or anything. It makes us run a little rich but besides that nobody really has problems with them.

nrg · 02-09-2005, 03:27 PM

just run a bit rich between shifts.
What if I had a MAP? vented bov won't cause any problems

timmybgood · 02-09-2005, 09:14 PM

i've never had any problems with mine, in fact i never even had to adjust it.

DudeYourSoOOJDM · 02-09-2005, 10:36 PM

HKS - had no leaks, sounded like shit.

Blitz - leaks under decel, makes my car shoot 3 foot flames at 1500RPM's. Sometimes leaks at Idle when I go for long drives.

Basically the HKS was way better, but I hated the way it sounded and traded for this Blitz that leaks. Both have been run open atmosphere.

Cars that I've driven w/ recirc BOV's seem to have slightly better response.

Car performs the same w/ both, boosts the same, SR has been running for over 3 years strong.

TurK · 02-10-2005, 12:18 AM

yeah ive been seeing threads like wtf!!!backfire YOo!!mmm....and most come to conclusion that is the open bov =D gatta re-circ

evilimport · 02-10-2005, 04:59 AM

Mine's an HKS SSQV thats not recirc'ed...engine runs practically the same as before it had the unrecirc'ed BOV, it just idles a bit higher now.... HKS doesnt sound like shit either.

well i think its just a personnal taste. everybody has their own opinion on the sounds of different BOV!

WeldingHank · 02-10-2005, 11:00 AM

i run an open BOV on my CA18 with pull through MAF. never had a problem with it ever. cept for the occasional flame i p00p during hard driving.

blue109 · 02-10-2005, 01:13 PM

my Tial cant be re-circd. and fireballs are cool.

timmybgood · 02-10-2005, 11:15 PM

fireballs ARE cool, however, i've never shot any(as far is i know), i have a greddy-s and i like the way it sounds

EchoOfSilence · 02-11-2005, 06:31 PM

I had the impression that the fireballs would damage your piping/exhaust.

are the stock recircs the only option we'd have if we wanna run that way?

It makes the piping look sexy. Burnt ass tips you know. My type-s leaks under decel but since the adjustment screw is stripped....i'm stuck with flames. I wish i had a ssqv though. I like the whistle as much as a type-s and the pull type valve is very atrractive now.

mr_240sx · 02-11-2005, 06:43 PM

I have a type S and have no complaints about it! It doesnt hurt my performance other then running rich between shifts!

TheTimanator · 02-11-2005, 07:09 PM

if your running a standalone computer or some type of piggyback computer you can make it so the car doesn't run rich, correct?
I'm still a little fuzzy on this...

that would be one of many reasons to have a stand-alone....

who cares looks so fucking cool LOL its worth it 100%

focused · 02-13-2005, 03:52 PM

i've got an ARC that leaks on decel abit.. but i like everything else about it.

wutangben · 02-18-2005, 09:40 PM

I recirced my GReddy Type-S last weekend, and let me say it's one of the most satisfying things i've done. The car feels like a normal car now... The only downside (if you even consider it a downside) is that you don't hear the BOV as much... The car runs so much smoother now though, I'm lovin it.

mr_240sx · 02-18-2005, 10:21 PM

did your sr run rough when your type s wasnt recirc? cause mine runs really smooth and its not recirc!

Campos · 02-18-2005, 10:37 PM

yeah i had the type shit on mine too i tried it both ways, chicks dig flames... runs perfect open atm.

SPEC_R_SILVIA · 03-03-2005, 12:27 AM

hey anyone want to know a liitle secert i relocted my MAF to the cold pipe of meaning right before the TB car idles better spools better quicker response on the the gas and am also running a vented Blow off vale as will but am not runing rich at all and no fireballs out my tail pipe which i do miss [IMG]

is it safe to put the maf all the way over on the tb?

i don't think he's putting it ON the TB, however if you relocate your MAF to somewhere in the IC piping after the turbo, you'll have whats called a "blow-thru" MAF setup. this is supposed to ameliorate the issues of atmospheric venting because only what passes through the MAF actually goes into the engine. as opposed to blowing it off after its been metered by the sensor, which will send incorrect data to the ecu.

WILDACEX187 · 03-03-2005, 01:52 PM

this wont have a negative effect on the maf element?

timmybgood · 03-03-2005, 01:59 PM

i don't think so, but i'm not 100% positive, maybe someone with a blow-thru will chime in?
