this is true, I have a 1" nipple from my hot pipe to the stock BPV. This was actually accidental that because I have what can be considered to be the first generation SLS Hot-pipe which has a 1" nipple on it. I think SLS changed the nipple back to 3/4" after some members complained about having a hard time fitting tubes on it.
What blowoff valve are you running?

BOV's do not affect performance. Your statement is illogical.
hehe unless in some way they don't have it hooked up or installed properly

He had all the washers installed? which would cause a stalling issue... not "make the car slower" issue. Its a mindfuck.... haha Im at stock boost with 0 Washers in my TurboXS....
idk why it mae it slower. I tried all washers, less washers no washers even lighter washers that didnt come with the valve, my car just didnt like it. I don't know what to tell you. I sold it to sandspeed, seemed to work for him apparently.
Never had a problem with any greddy valve though.

every BOV will cause stalling issues if you are venting all the boost w/o relocating the MAF. MAF is not designed to be under boost (that is one reason not to relocate it) and venting boost to the atmosphere is a waste of boost (dump it back into intake)

Why is it you want to run a BOV? to get the cool sound? ridiculous! dump the boost back into intake. that is about the only thing Mazda got right. Not smart to relocate the MAF, it is not designed to be under boost.
This is what can happen when your BPV goes bad (blew hole thru my relocated MAF

It WILL cause a rich condition between shifts or letting off hard, but doesn't have to cause stalling... Blow through MAFs have been used for literally over a decade with no associated issues. Even professional tuning shops featured in Magazines, are using blow through MAFs. You're right though, they were not designed to take boost.
Recirculating has it's values, but to those running a gt2554r or any other small turbo, we don't need that little bit of air to help us spool, as we already have a annoyingly fast spool time that falls on it's face @ 5500 rpms and up.

And the argument of BPV vs BOV will always be there. So just a FYI try not toget into "bpv is better because..." stuff, it's all in theory, never saw it proved. That can go eaither way.
But to run a BOV you need to relocate your MAF, if you don't it's stupid not to because the callig issue will always be there and you can't upgrade boost easily. Only worth it not to if you have a standalone.... Because then you control everything.

ive always been told, unless your runing ~20psi then BOV's are usless and only for the sound.
the BPV was the smartest thing mazda did with our cars IMO

Completely agree, BPV is the only thing they did right in my opinion.
Agree w/the 20psi also, which would be crazy to do in the MSP

Naa I don't agree, but this ISNOT the thread to talk about this. It's already been talked about.
