sometimes you can't have it both ways. In reality your car probably wont run like crap in the short term, but you will be running even richer than the car already is which may cause your spark plugs to build up residue quicker and your car to waste gas.

Yeah, recirc is definitely the way to go. You may not have any problems with stalling or fouling, but the fact is, the ECU compensates for the amount of air it sees come in with fuel, and if you dump that air out into the atmosphere, you have a shit-tonne of gas pouring into your chamber that can't be burnt off. Stalling and fouling are possible consequences, but the real kicker is that you will most likely lose power as a result. I'd put money on the people who say they've done it could dyno their car and show you the difference, even if they can't feel it.

i have run my greddy in both.
sounds better VTA but lost LOT of fuel mileage, ran 100% fine though
recirc will sound just as good if used with a CAI, and keep your mileage, and not burn up your cat, and spark plugs.

In my opinion just because it doesn't do any damage to the car doesn't make it right. Why would you sacrifice gas mileage, spark plugs, and your CAT for a BOV noise...get a recirculating BOV. Again just my opinion. In another thread someone said you could move the MAF so that it accounts for the venting in the atmosphere. Here read this thread. http://www.mazda3forums.com/index.php?topic=66567.0

you cant just move the bov on this car...
1) there is no room for it on the boosted side of the tubo.
2) a maf that is drawing air through it, and one that is forcing boost through it read very differantly, you would need a new meter, or at least a reprogrammed meter. i had to use a pro-m meter in my boosted mustang for this reason..

new to turbo's as well but VTA does stand for Vent to Atmosphere which has been said to make the car run rich.

with the ozmazdaclub post - we are not by law able to run VTA BOV so most of us will be going for the TurboXS plumb back version as its been made for our MPS's

Excellent, really captures the spirit of VTA for me. Also, for the loss of power that results on the MS6 anyway, check out the BOV Recirc dyno and the same guy's BOV VTA dyno here:

http://forum.mazda6tech.com/viewforum.php?f=52

171 hp / 197 torque on VTA vs. 196 / 227 on recirc (Mustang dynos).

Ok here is the deal...when you order your BOV kit it will (usually) come ready to be used in VTA (Vent To Atmosphere). the box you order should include an add-on piece that can be attached to the end of the BOV to use it in recirculation mode. The part that you are speaking of on the "right side" IS where it is set up in recirculation mode. It is important to run it in recirc. until you get it tuned to run it in VTA. As im sure you have read on here, it can cause alot of problems over time if you run the BOV in VTA while running it rich between shifts. If you talk to most of the people on here who know a little bit about turbo engines, they wil be running their BOV in recirc. and purchasing a CAI of some sort. You will still get that sexy pppssshhhh!!!!! noise that we all want.

I hope this helped, if not let me know and I will try to do better next time.

I would love to Im just waiting for 2 important things...the first is the shipment of the parts to arrive, the second is the shipment of the car to arrive!!! haha it should be here in march (i hope).

If you go onto youtube.com and search for BOV sounds, or Blow off valve, or anythign to do with it, it will come up with what you are looking for. Last I checked, there was nothing from the mazdaspeed 3, but there are some with the HKS in recirc with a CAI. Thats the best I can do!
