I'm so tired of people getting BOVs for the sound. I think that's actually the main reason that some people get turbo cars. 
I would be more concerned with how well it works than if I get some "cool sound".

The SRT-4 is not MAF equipped, it has a MAP. 2 bar to be exact. 
therefore it can run the open atmosphere BOV.
There is really no performance gains between the 2, except the sound. I personally like the way it sounds now. Its like a Rally car BPV.
Edited: to avoid flame's.

first off we don't have a BOV we have a BPV. Our cars can use a BOV.
you will get a considerably louder sound from the bov and an open air intake. you wont get any gains from the bov....but in my opinion it is the better way to go for longer life of the turbo.

:wtf: easy killer. just lending my .02
if you have performance questions go to the performance section. or better yet go ask a mechanic and roll your eyes at him

You are right that we can use a BOV...........but on a "stock" MSP you will hinder performance.
As we all know the BPV is meant to recirculate air back into the Intake manifold. The MAF sensor is setup to use that recirculated air and allocate fuel for that air. If that air is not there, then too much fuel will be dumped into the cylinders and will create a bog between shifts, some vehicles may even stall. With our existing fuel maps this engine runs extra rich as it is. Any more fuel would be double trouble.
A fuel computer can be used to correct this (Perfworks).
Most guys (DSM, Toyota, Nissan) use an S-AFC. As we all know we cannot.
Supras use HKS VPC (Vein Pressure Converter). Which converts the car to Manifold Pressure Sensor. Once again we don't have this luxury.
There are many good BPV on the market.
HKS Super Sequential (Popular Choice) has a recirculation kit availalbe for it.
Hope this helps.

1) you're the one that came in guns blazing w/ the BOV not BPV comment. Just sounded a little hostile...to me.
2) How are you gonna get better turbo life w/ the BOV? A BPV sends the air back into the intake tract. A BOV lets it out into the air...either one of them will do exactly what it's supposed to: let off excess boost so it doesn't eat your turbo. A faster acting replacement BPV (like I have) will do as well if not better than a BOV. In other words, I'm just curious and confused as to where your last staement came from.

there was no hostilaty intended. i am a close anquantance to a performance mechanic ( Tim Allen) who has filled me in on all there is to know about turbos. so i was just lending my .02 my apologies. i will just let you ask me personaly next time you have a question and i will stay out of the forum.

Man...you people take things too personally. I was seriously wondering why an BOV is better. That's all...doesn't mean you have to stop posting.
If you thought *I* was being unfair, I apologize...There have been quite a few people who come on here and act like know-it-alls; There's been more than one thread that blew up from someone *having* to point out the we have a BPV and not a BOV. That was several months ago, so you weren't here for that, but I was just trying to say chill, guys. Didn't mean for to come out any other way.

we can use a bov, we just have to recirc it
if you change the location of the maf it can be vented, but i assume our maf would have problems with being moved, so you would have to change to a different maf, then find a way to convert it. if you want the noise, switch to a standalone that uses its own air sensor, replace all intake piping, then your car will be worthy of the bad ass noise that you can emit.MSPDAVE125 said:
so if I udnerstand this correctly, once the ECU gets flashed and our a/f mix is leaned out, running a BOV would probably just put you back to where u were before the flash? having some hesitation and bogging, but because the mix has been leaned out, it would no longer cause stalling?

yeah i think its cause of "that movie whose name we dont speak of" that people now mainly want the damn sound and not the actual performance and prob wind up blowing up their cars.

No.... Not under throttle. A BOV will only cause flooding between shifts. And this will always be this way on cars equipped with a Air Mass Sensor. Depending how much air is not "seen" by the Air Mass Sensor will determine if the car stalls.
Your ECU flash will write new fuel maps and Ignition maps to curve the A/F mixture
Like I said before a re-circulating kit is available for most BOV. But there are also 50+ Diversion or Bypass Valves on the market.
Fuel computer can fix this problem as well.

Honestly, I considered doing the BOV install for the cool sound...but decided that it wasn't worth it. Yes, it's a cool sound indeed, but who needs the hassles of little ricers pulling up and wanting to race? Now that the SECODN installment of that movie that shall not be named is out and stuff....cops are being a pain in regards to "racing". With the bypass valve, it allows us to run our MSPs like they should be.....a sleek stylish (almost sleeper like) performance sedan.
Just my 2.5 cents....don't flame me!
