BOV how-to question

[borderline]

Hi!
I would like infos on how to connect engine hoses on my old HKS BOV.
Seems to be a very stupid question, I know, but I need to learn! :)
p.s: I have the flange that fit my engine (not pictured)

Here is my BOV (ignore the T pipe):
http://i20.photobucket.com/albums/b217/mazdaracing/hks1.jpg

and my engine bay:
http://i20.photobucket.com/albums/b217/mazdaracing/HKS2.jpg

question 1: Is that possible that my BOV is only VTA? cause I can't connect my hose #1 on that valve...

question 2: If my BOV is a VTA, can I use it on my car?? If I can, what do I do with hose #1?

Any help is appreciated!! I'm very new in the turbo's world....
(ugh)
THANKS!

bump cuase i got nothing???

I couldn't see your picutres, but i thought this might help.
This is just a general link for BOV hook up. http://www.turboxs.com/faq/turboxsrbv.htm
I'm under the impression that the BOV on the MS3, (which you have?), is a recirculating one.
Hope it helps some.

I hooked up an atmospheric bov to my friends 240, which is naturally recirculating. All we did was block off the port in the intake for the recirc fitting. He eventually got a pipe made with no port in it. It cost him like 15$ for the muffler shop to make the pipe out of steel, then he painted it black. Hope this helps.

Yes it helps!!
Thanks nocoastgangster and kytuner!

Yes nocoastgangster, my oem valve is a recirculating one...

[boostdog]

then won't that cause u to run rich? it does on other cars with rec. bov's. i donot have an ms3 but thought that would make sense.

That all depends if the Recirc BOV pushes the air into the intake before or after the MAF

If the Mass air flow sensor sees the air go into the intake, and then it leaves the intake via a bov, the MAF will add fuel for the incoming air, but the air will never get there. Hence yes, you will run rich, if the MAF saw the air before it vents, which in most cases, it does.

Hello guys,

My name is Jermaine, I work for a company called TurboXS. You may or may not have heard of us. I just wanted to give you guys a heads up that we do have a bov mount kit for the Mazdaspeed 3 & 6.

If you are interested please give me a call at 301-977-4727. I will be posting dyno plots of our shop Mazda with modifications soon. We also have a boost controller upgrade, short ram intake and fuel computer upgrade available.

Later,

Woot TurboXS, I have super distand relation to them lol. My mother in law's uncle or something I thin kis an owner or patial owner... I dunno lol. Great company omg :D

LOL. That reminds of the scene from Spaceballs where Dark Helmet says "I am your father's brother's uncle's former college roommate." or something like that.

My name is Mark and I am one of the two owners of TurboXS. The other owner lives in Australia. My only niece is about 7 years right now and last I checked she was no one's mother in law so you might have the wrong company, but thanks for the compliment!

In any case, as Jermaine said, the BOV adapter kit for the MS3 and MS6 is ready to go! More cool stuff is on the way. We will posting more info next week after the Thanksgiving holiday.

And to actually add something useful to this discussion, a vent to atmosphere BOV like our RFL will cause the car to run slightly rich for a brief second after the valve vents to atmosphere for the exact reasons Equinox posted. You will even get a little backfire now and again with a vent to atmo BOV installed on the MS3. Of course, you also get a cool "Ka-Chhhhhh" when you shift. Ah, life if full of tradeoffs...

BTW, we are loving the MS3. I haven't driven the EVO, WRX, or STi home since we got the MS3! I look forward to making a great car even better.

You don't perhaps know someone that works there that knows Ann Vargo?

Mark- Is the whole running rich going to cause any problems down the road? Do you guys have any plans for ECU upgrades?

[Equinox]

running rich = worse mpg, sometimes worse horsepower, as it is less efficient, and in some rare cases it can call stalls while you are driving mid shift. Nothing I can think that is permanent though. As far as stalling it's usually when you gun it hard, shift, and completely let off it, so it's not all that common. Ultimately the car wasn't designed for it, and if you want to run some sort of BOV, I'd suggest one that is 50/50 half recirc half Atmosphere, that way it's less traumatic to your car. I believe the MSP has one for it that does the same thing.

At worse your car will have a burble and maybe lose a horsepower or two. Not healthy, but it works. Also your muffler may start getting carbon build up (black)

[PRO 5]

My car already had carbon build up on the tailpipe! LOL! This car runs so rich it's rediculous. Can't wait for COBB to finish the AccessPort and lean this car out a bit. Should see some good power gains.

[benzo]

Man i thought i was the only one have a ton of carbon coming out of the tailpipe. Every time i am done driving i have to clean the tail pipe cause there is so much. Is there anything we can do to lean it out a little bit?

[Equinox]

Yeah I guess mazda turned up the richness for safety. Figured tuners are gonna turn up the boost anyhow. that's my guess.

[benzo]

Well i called up a performance shop here in town. I have an appointment with them on Monday to talk about some potential HP increase. I would like a boost gauge, BOV, ECU upgrade of some sort, Wastegate ?. So we will see what they recommend for this car. I really do not want my brand new car to be test pig cause i need this thing to run everyday and not void my warranty. I will post my findings out on Monday night.

[Mspeed3]

Im getting mine dyno tuned to lean out the A/F ratio. I'll let everyone know how it works out.

Sean

[benzo]

Please keep us posted.

[TurboXS Mark]

Mark- Is the whole running rich going to cause any problems down the road?

Typically, there are no long term problems caused by running a vent to atmosphere BOV. Like I said above, you will get some minor backfiring and you could get slightly worse gas mileage. I suppose that in a worse-case scenario, running rich could cause premature catalytic converter failure, but that is unlikely.

Do you guys have any plans for ECU upgrades?
We are considering all our options with regards to engine management but I can not commit to anything at this time.

Man i thought i was the only one have a ton of carbon coming out of the tailpipe. Every time i am done driving i have to clean the tail pipe cause there is so much. Is there anything we can do to lean it out a little bit?
Nope, we all have it. The MS3 does runs pretty rich from the factory. Under full load our MS3 is running AFRs ranging from a merely "rich" 10.8:1 to a "pig rich" ~9.8:1. However, this AFR is fairly typical of a factory turbocharged car. If the MS3 is like the MS6, you can lean it out with a fuel computer (Shameless Plug: Like our DTEC-FC :) ). We made significant horsepower gains on the MS6 with just the DTEC-FC. We will see if the same holds true for the MS3.

Mark- Well I think I am going to go with a Greddy Type RS BOV with the recirc. fitting. I know the sound really isnt going to be as loud as I would like but really dont want to chance anything just yet.

I really would like to lean out the car a little bit. So please keep us posted to your findings.

[WTF MATE]

I'm going with the CPE kit "The RPM Store" sells for the mazdaspeed 6 same motor and the flange is built to fit. Also it comes with the HKS Super Sequential BOV which can be adjusted from 100% recirculate to 100% vent to atmosphere. Seems like the best choice for anyone IMO. 289 might be pricey but it beats buying another one down the road if you would want to switch to VTA.

Really I didnt know that the HKS Super can be adjusted. I might have to look into that. Even though it is for the 6 it should work for the 3 right?

Disregard that, I talked to them today about it, apparently the flange for the 6 is a little different then for the 3 but the one for the 3 should be out they said in a couple weeks. I can't wait. Too bad though I wanted to get it on before I drove up to Philly for Christmas.

I'm sure they will be able to help you get a boost gauge/install it for yas, any you might even get them to help you with the BOV situation, most likely though they will just give options as to what you can pursue, as it's such a new car and they might not know jack about it.

ECU, what are you looking to get out of the ECU, or do you just want to adjust air/fuel, as an ECU mod will cost you a bundle especially this early on in the car's run, you might be better off with going with the DTEC-FC from Turbo XS, although I've never used the product myself, TurboXS has a way of taking care of business. If you are thinking along the lines of a chip for it, I'm pretty sure nothing is available just yet, however they are mostly just static versions of a fuel controller, making the car more efficient and tuned towards modding, which is the point of the DTEC-FC, but it's customizable.

Lastly as far as wastegate, your turbo, I believe, is equipped with an internal wastegate, and if you want to get an external one that you can properly adjust boost with, you will need to replace the turbo entirely, which in most cases involves replacing of the manifold and intake piping as well. Your best bet is to just go with a manual boost controller, which is more or less a controller boost leak to the wastegate, lying to the wastegate as to how much boost the turbo is putting out, making to turbo put out more, ie, more boost, or less, if that's your bag. I know TurboXS can easily set you up with a MBC for sure.

The mushroom looking item I believe is the acutator for the internal wastegate. If you could take the same picture but zoom out a bit to get a better idea of the layout that would help.

EDIT: http://www.mazdas247.com/forum/showthread.php?t=123650712&highlight=zoom+live
Look at post #4.

[mdl247]

its called an internal wastegate cuz that mushroom thing with the rod going down the middle goes to the turbo. inside of the turbo exhaust side there is a flapper that is sealed shut until you hit the boost application limit and opens up the flapper to stop it from overboosting. An external wg is like what you find on the aftermarket deals for the n/a apps. it does not what so ever have a rod coming out of the middle for the external wg. also it looks like a mushroom that sits directly on the exhaust mani.

Don't understand why the flange would be different from the ms6 to the ms3 they are both the same exact engine. I have the HKS SS on my ms3 and my friend the same flange and BOV on his ms6. Don't know where your getting your info from.

I can also say it would be better to recirc. As mentioned we already burn to rich from the factory. No need to burn any richer. With that said, my HKS is very loud. It is awesome. It is so loud sometimes i think i might have come loose....lmao.

[Boosted03MSP]

Awesome you guys at TurboXS are making things for the MS3 and MS6. I am in Maryland, not that far from you. I think a friend of mine John knows you guys well. He is the owner of Speedesign. I havent seen him in awhile though. You gyus should look into making parts for the Mazdaspeed Protege too ;)....ehhh just wishful thinking, haha

[borderline]

Damn!
I think this was my first thread here...(old one!!)
everything is fixed as I bought a new HKS. This old one (pictured) was not designed to be in recirc.
everything works well now! (first)

[Bugalydosh]

argh... what do i do about a turboxs BOV to a MSP without having to weld and being able to return it to stock later on?

[snooky]

this may sound like a dumb Q, but i know nothing about turbo's and BOV's... I wanna buy one for my MS6, does any BOV work, or does it have to be a specific one for my car? and is ita long install?

thanks

[knowledge007]

NO intall is very easy and any BOV will do as lond as you have the correct flange to hook up the BOV to the intercooler. I have an HKS at the moment is pretty decent and love it. I can go vent to atmosphere or recirc. For these specific engines we must recirculate due to the ECU calibrating for the extra air coming back into the engine.

thanks, one more thing does it add any HP? and would i have to costum make the flange or can i buy it too?

[knowledge007]

Negative, flanges are available. Just depends on which BOV you decided to get. But I am sure which ever you get there will be a flange available.

what flange should i get for my ms6 if i get the same bov as u?

and when i install it is it a basic bolt on, like replace the existing one?

thanks again

[dread]

BOV will not give you any horse power, and some people have experienced problems with them and actually lost power.

soo then whats the point, if it doesnt give any HP?

do be honest the only reason why i want it is for the cool sound and thought it added power.

thanks

[uncletime]

how dow i get the c-clip on the hks? any suggestions? seems impossible to me lol

c clip pliers. Sears has a good one. Bought, used, returned.

[uncletime]

ha thanks for the advice

[Nutari]

ha thanks for the advice
no, trust me. I tried to use other tools ..3 hours later, nothing works. C clip pliers.. 5 minutes.

I would reccomend to purchase your BOV, if you would like the same one I have, from CP-E (Customs Perfomance Engineering) they will supply you with all the necessary parts including flange.

Yes it is a direct bolt on that will replace your BPV. They will include picture instructions.

[uncletime]

no, trust me. I tried to use other tools ..3 hours later, nothing works. C clip pliers.. 5 minutes

i trust you. i wasnt argueing that. i was laughing at the fact that you used them and returned them.. i like that idea. i can see that it looks like nothing else would work

[uncletime]

can anyone tell me what i with the hose that leads back to the intake? do i plug it up or what?>...

[knowledge007]

what are you talking about, what hose...??? there are only two hoses that plug tot he BOV if you are recirculating.

[uncletime]

yeah its the bigger house at the bottom towards the intake... the house that recircs back into the intake... i plugged it up already

[knowledge007]

good you are set to go, just make sure there are no kinks on either hose.

[uncletime]

nope, no kinks (headbang) sounds good though everything is gold

[speedalot]

i have a greddy rs bov without the recirc kit, but within the BOV i only have 1 spring. it comes with 2 springs, 1 bigger and 1 smaller. i pulled out the smaller one so that i could try and use the BOV on my MSP but didnt work out too well and i missplaced that smaller spring. can i still use the BOV with 1 big spring and not have any problems? im going to be putting it on my MS3.
