Someone Explain.....

[MoJoeTCM]

You guys have made some many threads about BOV's i don't know what is right or wrong....I have some QUESTIONS!!! OK! If i were to buy SPOOL PERFORMANCE's HARDPIPING with the BOV flange for a HKS SSQ BOV, would my car not stall if i tightened the BOV a little!? If this does work...would i still have the hissing noise? Because i am not risking rear ending a mercedes in traffic for a qweef noise ha!

 

[MoJoeTCM]

ANYONE!???!!!!!

 

[Striker187]

if you don't recirculate, your car will stall. unless you have fuel management or you change your driving habits, there's no two ways around it if you vent to atm. tightening the bov a little won't help. tighten it a lot will help a little, but then you're defeating the purpose of a bov.

recirculate and forget about the problem.

 

[boostisgood]

Go full standalone, lose the MAF, and not worry about it (if you gots 2k to drop in a stand alone)

 

[MoJoeTCM]

DAMMIT! SOMEONE NEEDS TO MAKE THAT FUEL MANAGEMENT THING!!!!!!!! it can't be that hard! a bunch of cars have these things....SPOOL or whoever needs to get it together...why sell a product that ISN'T compatible with our cars....that is maybe why no one wants the hardpiping! Cause it DOESN'T WORK WITH A BOV!!!! AHHHHH!!! had to let some steam off.....whew

 

[Striker187]

ummm....spool IS working on a greddy emanage program. and there IS a piggyback available from modern performance. and there IS a standalone that will work with our car.

 

[MoJoeTCM]

but for about 2,000? Who would want to pay that much money for a bov noise! Why can't our car just be like a honda with a turbo....plug and play....damn....

 

[EvilMSP]

Striker I gotta ask one question, this is not a thread jack I just want a quick clarification.

I understand why the engine stalls with a BOV, unless you re-circulate the air into the system. So basically all you are doing is making a little loop? Also does the BOV loose any of the cool sound when you recirculate? Thanks

 

[MoJoeTCM]

could i place the BOV near the intercooler like a WRX? i would just have to buy alot tube for the vacuum tube...that sounded dumb....

The design is not the same between Greddy and HKS. If you tighten either one it will not vent as much to the atmosphere and therefore your maf will get a higher reading...
When you tighten it down you risk back-surge (I know this is not the necessarily right terminology, but it is late for me and I am trying to answer this!). You will still get a hissing sound with tightening it down, but it will not be as loud and with the Greddy it will not be consistant. Hence the gobble gobble.

 

[DiscreetSpeed]

no stalling here with a turboxs type-h.....

 

[MoJoeTCM]

discreet speed are you venting? and if so what type of setup do you have...can i copy you

 

[ricenudles]

yeah seriously...

I've been reading BOV posts for the past 3 days trying to piece things together, but everything contradicts each other. Plus every time an interesting BOV thread starts, it ends with the damn turkey issue and where it comes from (quit it already).

First i wanted a HKS SSQV but i gotta recirculate in order to not to stall. then, i read somewhere that the HKS SSQV is NOT meant to be recirculated and sounds like s***???

Also, no one ever mentions the blitz dd. does it suck like hard nuts or something? my friend INSISTS its badass (no clue where he's gettin it from though).

it would be great if someone could clear it up (finally)...thanks!

 

[MoJoeTCM]

ok see....i am not the only confused guy in this forum....so SOMEONE! help us out!

the hks ssqv was not meant to be run recirc'd, but it can be adapted to. our car was meant to be run recirc'd.
the purpose of the bov isn't to make a noise. if you must have the noise, make your car worthy of the noise first (i.e. the standalone) then upgrade the bov, or buy the bov simulator so you won't even have to build boost to have the noise. a bov just vents air so it doesn't go against the flow that the turbo is creating. simple concept. if you need any more questions answered, even though they've all been answered already in one thread or another, just ask and i'll try to be kind

 

[ricenudles]

thank u jred for not flaming on me
but seriously, u have to admit that 90% of the ppl talking about bov want it to make that sound, right? one more thing though, is the msp like the only car thats made to recirculate? like all of my honda friends dont kno anything about it.

 

[jred321]

yea, i dont get why people want the loud sound, it's cool and all but for me my money could be better spent. if i was upgrading pipes then i would change, but before that it's just an expensive sound. even then until more boost is pushed to make the stock leak it's still just an expensive sound, but i'd rather do things right once.
hondas use a different kind of sensor (MAP, ours is MAF) so they can vent. they get readings on air based on pressure, we kinda count air going in, so the air it counts must stay in the system. any maf car should recirc, dsm's, se-r's, etc... all use a version of maf, so they should recirc and if they don't will run into the same problems we will by venting, if not worse.

 

[OpticalElusion]

is something wrong with stock MSP bov? Does it have the plastic tip that isn't reliable under high boost or does it have a aluminum tip? Is it even a BOV or is it a diverter valve like a GTI? I personally like the diverter valve sound. My friend had a GTI boosting 16 lbs with a diverter valve and intake and it gave a mean puuushhhttt noise.

 

[Black Majik MSP]

Get the Forge BOV that I am going to be testing within the next week or so. I can't explain it that well, but it vents to atmosphere & won't stall because of the dual piston design. It also won't mess with the MAF readings because it is only atmospheric for a split second. George from Forge Motorsports explained it to me in detail, but I'll see if I can get a description for you.

 

[Striker187]

optical - no, nothing is wrong with the stock bpv. and yes, it is a bpv, not a bov. i'm not exactly sure what you're talking about with the plastic tip....

ricenudles - check out my sig. i'm going with the blitz dd with a custom recirculation fitting most likely.

wilsman - correct. you're making a loop. you'll lose a little sound volume when you recirculate but it won't be major. just be careful with the hks. the hks ssqv requires the removal of the fin insert to use the recirculation fitting so you WILL loose the whistle if you recirculate the hks.

motec - if you're gonna use a bov (not a bpv or recirculated bov), then yeah, put it anywhere your heart desires.
