Aftermarket B.O.Vs

hardpipes. i don't think you can run the rfl off the stock pipes. i'll check.

EDIT: ok i take it back. it may be possible to run the rfl or any turbo xs bov with the stock piping. they make adapter flanges to fit the greddy flange or the hks ssqv flange. if this is what i think it is (i didn't see any pics in my cursory search), then this will allow you to bolt ANOTHER flange up to it which will then allow you to run a hose to the inlet. you can find the second flange at www.8vturbo.com.

so wait you can run a turboXS h-rfl but you have to do what? i just learning about my engine and all thecomponents.

ok, first off, call the place you bought the bov from and ask them about either the greddy adapter flange or hks ssqv adapter flange. make sure that this flange will allow you to bolt the rfl onto the flange that greddy/hks bovs normally use (i can't find any pics of the turbo xs adapter flanges so i'm not 100% sure it is what i think it is, but i'm pretty positive). if they say yes, buy one (try the greddy, i dunno, just cause).

pay a visit to www.8vturbo.com. they sell a flange for the greddy type s that will bolt up to the bottom of a greddy type s normally. however, since your rfl will now have the same flange as a greddy bov, this will work for you too. so buy the second flange.

now it's a simple procedure of removing the stock bpv and replacing it with your setup in a similar fashion. use a pair of pliers to loosen the normal clamps on the bpv tubes. DON'T remove the clamps that keep the hoses directly attached to the bpv. you don't need to or want to. once the stock bpv is out of the way, you'll need a 3/4" hose to connect to the intercooler piping nipple and a 1" hose to connect to the inlet of the bov (i.e. the flange you bought). you may be able to get by with a 1" hose connected to the ic nipple, i'm not sure. but if you do it the way i've said, just slip the 1" hose over the 3/4" hose and attach the correct end to the ic piping, and the other to the bov. cap off the inlet nipple on the intake piping side and you're done. be careful though, you WILL STALL under certain circumstances because you''re not recirculating.

lemme know if you have any more questions.
 
hey man thanks a lot. ya i d have acouple ?'s, will i have that ear piercing loud rfl pshhhhhhhhhhh and how do i keep from stalling? also the 1inch and the 3/4 inch tubing stuff, if the 3/4" pipping connects to the ic nipple then where does the 1" tubing connect? thanks again. ohh about the flanges the first flange i have to ask the b.o.v seller to see if they have an adaptor that will mount on the rfl and the second flange adapts to the adaptor flange on the rfl and the ic pipping? most likely the greddy flanges.

yeah you should have a pretty loud sound. it may not be maximized though because you have to realize that you're only releasing pressure through a 3/4" hose. if you look at the actual inlet size of the bov, it's not 3/4". it's probably not even 1". so if you were to get hard piping and get the weld on flange with the huge opening, you'll probably get a louder sound just cause you'll be pushing more air, faster, through the bov. but by all means you should have a loud sound. the stock bpv is already pretty loud by itself with just an open air filter.

to keep from stalling, you'll have to recirculate, which, i'm sorry to say, i don't think it's possible with the rfl. you may be able to get someone to make a custom flange for the bov outlet but that would mean removing the amplifying horn and other stuff.....i'm not sure it's possible because this bov wasn't designed to recirculate.

the 1" tubing will connect to the adapter flange. if you take a look at the pic off of the 8vturbo website, you'll see that 1" inlet on the flange i'm talking about....that's what the 1" hose will go to.
 
are there any bov i could get that recirculate and have a loud pshhhhhhhh sound? also if i used a rfl coudlnt i turn up the idle to compinsate for the lack of air?
 
I think w/ recirculating, your always gonna get the turkey...(if I'm wrong, someone feel free to correct me)...it's because your putting the pressure back into the intake pipe....thus the turkey sound. release to the atmosphere, and you get to sweet pshhhhhhh.
 
i checked out that thread and what he was saying about just turnning that set srew all the way counter or clockwise cures the prob. what do you think Striker187?

i've heard otherwise. turkey either way. i agree with the slight compressor surge theory, thus recirc/not recirc has nothing to do with it, but there hasn't been a definitive answer, just theories
 
from what i read, this only helps with stalling at idle. which is half of the problem we have. if you rev high and then shift to neutral, i'm not sure if you would stall or not....but i guess if you're idling at 1500 rpm, you're not gonna stall so easily. but who wants their car idling that high?

that's half of the problem anyway. the other half, as supman discovered is that by venting, you're still getting a rich condition......very rich...so you may bog down in between shifts. unless you get a fuel controller that will pull fuel when your bov opens, there's no complete fix for it.

personally, i'd still recirculate because: (1) this car was designed from the factory to recirculate. so why not recirculate? (2) i don't want my car idling that high.

now even though you'll still probably encounter some slight compressor surge from recirculating (i'm almost positive that's what the turkey is now, caused by the return tube not being large enough, stock or injen), your car will still run better if you recirculate. until you get a fuel controller, i wouldn't vent. why risk a potentially dangerous stall?

yes, there are bovs that you can recirculate and get the nice psshhh sound. 935motorsports has offered to design me a recirculation fitting for the blitz dd bov. if you've ever seen getaway in stockholm 2, the bov you hear is the blitz. the hks recirculated also gives a whoosh sound, distinctly different from the blitz. the hks gives a flat pshhh sound whereas the blitz has a slight pitch change/whistle to it. visit www.blowoffvalves.com to hear sound clips of different bovs. to hear the hks ssqv recirculated, visit http://www.collectracecars.com/evo/hks_ssqv.htm

turbo xs valves also give a psshh sound and turbo xs does sell true bpvs. i've never heard one of their bpvs but i imagine they will sound very similar to their bovs.

those are probably your best options.
 
is the sound clip of that blitz bov a recirculating bov? also what are the fuel mods you are talkin about. ok if i get this right, i can get that fuel mod for my msp then i can run a non-circulating bov.? thanks again everybody you have all been a big help so far. i just hope i will figure this out so that i can get myself my BOV that has the nice pssssshhhhhhhhh as well as being a circulating bov!
 
the sound clips off the site are vented to atm. you should get a very similar sound with it recirculated, least that's what i imagine. i see no reason why the sound should change, except for the volume of it, and only slightly at that.

the fuel mod i am talking about is some kind of piggyback (or standalone fuel) fuel controller. something like an apexi safc, which unfortunately, doesn't work with our car. if it did, oh the possibilites. but so far there's only modern performance's piggy back that will work (i think it's $700). spool is coming out with a greddy emanage program for our car soon. or you could get the E6k haltech. i believe that's a standalone....very good, but very expensive.
 
Striker187...that evo website w/ sound clips is nice....gives a nice idea of how to go about installing the HKS SSQV (that's the one I plan to get, actually). It's also nice to know that I CAN get the good BOV sound w/ recirculating, and that the BOV I want can be set up that way. Now all I need is some money!!

Doggman...yeah, I did check out that whole forum....a lot of information, but note to self : this is "experimental"...I think investing in a stand alone or piggy back is the way to go when it comes to serious mods. Once again, good luck!!
 
so the only way i can vent is to get a fuel management system which they dont have for the msp or i cold just get a recirculating bov. And it will have the same sound as a vented but alittle quiter? also what about that flange you getting custom made, will i be able to get one so that i can hook up a bov, like the blitz, to my stock rubber setup instead of of metal weld on? also with that metal injen intake your talkin about will the nipple be larger then the stock nipple on the rubber pipping so that more of the air can flow? thanks -doggman ohh and Striker187 what was the price on the 5ziggen catback and is it sweet as in i should buy it. the only catback i ever saw was the thermal modded p5 exhaust that was only 2.5 catback. also the high flow cat, what did that caust and does it void warrenty regrding the O2 sensor???

well there are fuel management systems out, they just cost a lot. the haltech e6k (turboage is using that) and modern performance's piggyback. and if you wait, spool will come out with a greddy emanage program. if you get one of these, you'll be able to vent no problems.

yes, you'll more than likely have the same sound if you recirculate. exception is the hks since the recirculation fitting requires the removal of the fin insert. the fin insert is responsible for hks's distinct whistle sound.

yeah you should be able to get one. visit www.blowoffvalves.com. it's run by 935motorsports. send them an email. ask for robert. he's the guy i was emailing back and forth with. i'm not sure if he remembers my name but tell him that Ash told you about the recirculation fitting for the blitz bov. see what he says, and keep me posted too :) the inlet flange, blitz makes. it's basically the same as the greddy flange i was talking about made by 8vturbo. you'll be able to run a 1" hose to the bov inlet.

the injen return tube is probably 3/4" diameter. that's just a guess. i posted some pics a while back of my injen setup. run a search and you'll find it. robert mentioned to me that the injen return tube looks small so that may be the reason why those of us with the injen still have the turkey.

unfortunately, 5zigen does not make a catback for the protege. i bought the 5zigen muffler. i paid $217 for the muffler shipped. i'm getting custom piping made tomorrow. i'm posting pics of the muffler right after this (12:15 am Friday night), and i'll post pics tomorrow of my setup. once i get back to college, i'll have my gf take some vids of it so all you can hear how it sounds.

i don't have the hi-flow cat yet. i need more money :p but you shouldn't void the warranty by changing out the 2 cats for 1 hi-flow one. so long as you place the o2 sensor after the cat, you won't throw a cel and should still pass emissions.
