Im not sure where to mount it, Ive sort of decided on the hot side of the intercooler but I want to see if anyone has pictures of their setup, thanks.

I have the HKS SS BOV but it has the stock flange, so it bolts up to where the stock bov is, right off the y-pipe.

I have a V-Mount, and put it here...

That looks pretty awesome, but doen't it sound lower/perform worse closer to the tb than closer to the turbo?

most tuners say it performs best closer to the throttle body. when the throttle body closes, the air bounces back and needs to be vented quickly or it will hit the turbines and make spooling slightly longer.

Garfinkle has one on the greedy elbow and one on the Y pipe . Pm Rotorbrainfor pictures . I know he took some of the y pipe tonight .

so i take it where mine is placed is pretty ineffective??

(im usin dcrosby's pic, but moved the BOV to where I have it mounted...basically its venting one of the hoses off the airbox)...

Lots of debates on the subject, no hard data, just talk so I wouldn't worry about it.

Oh alrite. Thanx Mahjik. Cuz I was gettin a lil worried since I personally haven't ever seen anyone place their BOV where I have it, but that's where PFS put it so...

That's pretty much the stock location. I'm sure Mazda put a little thought into it as to where it should go back in the day.

seeing that there is 2 stock BOVs.. did you "join" the 2 hoses or just plug in the SSQBOV in one of the hose?

The two stock BOV's are not the same. One is the CRV which has a completely different operation than the BOV (or ABV as it's called on the car).

BoostedRex

Once you run the BOV in the IC piping instead of how it is run stock then you only need one BOV. At least that is the way it was explained to me. Please someone correct me if I'm wrong.

Yes, you only need one BOV (ABV) if you add an aftermarket BOV to the IC piping. You would block off the old valve outlet from the stock BOV but you keep the CRV if you are running twin turbos sequentially.

Flipn

So if you got an aftermarket BOV.. the CRV will still be needed?

Im a newbie so bare(sp?) with me here..

Mahjik

iTrader: (1)

Yes, unless you convert your turbo system over to non-seq (both turbos coming on at the same time), then CRV isn't needed.

BoostedRex

Once again, we are saved by Mahjik!!! Thanx as always, you are very handy to have around Mahjik.

Very handy to have around, lol, it sounds like your referring to him as a tool, a wrench or soemthing. Anyways, wha does the crv actually do? Is the fuinction really the same as that of a bov?

rdavidsrx7

CRV vents boost from the second turbo.....it only does this during prespool when the buterfly valve in the y pipe has the intake piping sealed off to the second turbo. It will also act as a blowoff valve if you go non-sequential. I actually have it acting this way along with the stock blow off valve because they are the same peice. (or really damn close so don't flame me if they have a different part number from mazda)

Oh yeah, my friend got his blowoff valve from Australia, paid half what the hks SS does and looks almost exactly the same except it says Monza. Wierd!

here is mine

I have a few pics of Garfinkle's setup...

this is the first bov mounted on the y-pipe



here's the second bov mounted on the intake elbow

duboisr

The Y pipe looks like the BOV flange was cast with the pipe . Extacy 7 how did your modified (stock ) bov work ? For the info,, Jeff who runs Turbo Auto ,in Nashville ,said the place to put a single BOV is near the throttle body .

phsst........ phsst......

why would you want 2 aftermarket turbos in different locations????
