Stock BOV/BYPASS valve hose

[acidboy]

i asked a fellow dsmer im my area this question he said he had no clue,
I was wondering if you disconnect the hose that goes from the stock bov/bypass valve bck into the intake thing will it damege the engin profomance?

 

[Green93TalonTSi]

I read that the car will stumble when u disconnect it, and vent to the atmosphere. And that ull be running lean or rich ( cant remember wich 1 ) when ur shifting gears.

 

[mikeydsm]

it makes you run rich between shifts. if you do it watch out your back window when u shift gears for that nice lil puff of black smoke.

 

[Prodigy]

You will run very rich...When the hose is not on the car it will feel like itz about to die at idle.. i dont think it will hurt the engine....but i only had it off for a few mins...

 

[L2RTSiAWD]

Yes it will hurt perfoemance tell your freind not to do it especially if it's a stock 2G BOV.

 

[Idiot Stick]

yah, it'll sound real cool, but you'll kill your car doing shifts, you won't be able to hold boost at all, you'll get poopy gas milage, it'll die at stop lights, and you'll get beat by honda's maybe, well maybe not. not a good idea, but curiosity won't kill the cat here, wont' hurt anything.

 

[acidboy]

but i have automatic, so it would be a bad idea to get a bov that vents to the atmospher right.

 

[nine5raptor]

auto, manual doesn't matter. don't do it unless you are at the point in your build up where this question should not even be asked by you.

 

[UltraImports]

if you want that sound, an aftermarket bov will do it for you while venting to the intake.

 

[nine5raptor]

just buy the ricer speaker and sender unit that makes the fakey HKS ss sound and be happy

an with auto you wont hear the "whoosh" when it shift , only when you let off the gas.

 

[acidboy]

so whats a good bov i could use to hey a louder than moded stock bov sound

 

[mikeydsm]

i like the GReddy Type S BOV. Gives a nice sound .

 

[abrxy3]

i vent with an hks ssq and have no stumbling, idle surge, stalling etc...only downsides are the 10 mpg i now get due to richness and my damn check engine light always being on! niiiiice sound though, scares the shyt outta pedestraisn and animals

 

[Prodigy]

i have the Hks ssq and i have none of the problems...sound like u have a boost leak of some kind...are the bov itz self is not closing all the way..

So you thinks its worth it?
thats the riciest thing ive ever heard IMHO

 

[L2RTSiAWD]

I have and HKS SSQ. also but it's vented back into the intake. It's not very loud but the BOV is very tight and I have no fuel issues.

this was for you guys that wanted the sound...I'm surprised this thread wasn't locked when it became "what's the riciest bov"

Just curious why would not hooking up the recirculation on the stock BOV make the car stumble?

edit: duh nevermind, cause there'd be an open hole where the recirc. is supposed to hook up.

no, even if you close that hole it will be ####ed up

all the air that has gone through the maf has been measured. say this air is on its merry way to your throttle body, when you slam the throttle body shut (foot off gas). the air goes 'whoop de shit i guess i gotta get the hell outta this pipe somehow' and conveniently there is a blow off valve there that opens for it.
if you are venting to atmosphere, the air goes PSSSHhhh out in to your engine bay. the ECU thought that air just went back in to your turbocharger, because thats where your damn dump return tube is supposed to route it to, but no, it goes out in to the engine bay, and your ECU is like 'ok dood theres some air that just got shot into the engine thruogh the dump tube im gonna spray lots of fuel into the engine k?' but the engine is like 'dood wtf where is this air, i cant detonate all this ####in crap' and all the unburnt fuel goes through your exhaust and out the tip.

damn i wanted to say that

 

[xjarayax]

Well I will be using it on a car not tuned from factory for the turbo- and am running it without the recirculation (just for now, to make it easier, project took forever), and haven't had any problems like that. I hadn't thought about it being a tuning issue, so I was curious.
