This is a discussion on "The BIG BOV thread" (Where all bov question threads get merged) within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; Forge and Perrin also make some nice %100 recerculating divertor valves....

if i recirculate with a greddy bov, will it give off any noise?
no
why would it
I want my subie back.
What's up all... I recently picked up an 02 wrx sedan with some upgrades. I am not really sure what the previous owner has done to it because I bought it from a dealer. From what I can tell it only has a few performance upgrades including a TXS bov and a Blitz nur spec cat-back. I am pretty sure that it has some kind of suspension kit because it looks like it sits a little lower than stock (although it does have RSL 18" elites).
The main question I have for you guys is; is the bov worth keeping or does it do more harm than good? I like the sound, but if it really is hurting the engine then I will just go back to stock for now. I have read through the stickys in the forum, but I would like some opinions on the subject. Please don't bash too hard, it's an honest question.
By the way, I will post pics asap.
Thanks
Most people on here will tell you that you should go back to the stock bypass valve. If you like the sound of the blow off valve, i would suggest you remove the intake silencer when you re-install the stock bpv. This makes the stock bypass valve more audible. If you search, you will find instructions on how to do remove the intake silencer.
why is it that every noob seems to miss the sticky that covers this exact topic, and many more??
lose the bov

Like I said in my post, I have read the sticky and was wondering what everybody's opinion was on the subject; Maybe it was you that missed something...why is it that every noob seems to miss the sticky that covers this exact topic, and many more??

Although I am no expert on these engines, I do not see how an aftermarket bov would hurt the car. I could see the possible decrease in gas mileage, but to harm the engine by simply depriving the engine of air (richening the mixture) is what I don't understand. Is there something else going on that I am not thinking about?
No offense to Chromatica, but this is an honest question in which I am looking for additional information from what is posted in the short section of the sticky.
Like a few guys already said, your best bet would be to go back to the stock BOV until you need a new one. Some people run BOV's without problems, Some have alot of problems, I had the Rfl bov on my WRX when I was stock and I would turn on my car and it would stall right back out sometimes.
I have a TiAL BOV, 4 Inch Intake, No MAF Sensor, Hallman MBC and Completely Lack a Subaru ECU... I must be a noob!
not flaming, but the facts of the matter are simple: stock bov > aftermarket....for a variety of reasons. But do as you wish. "to each, their own"

Its not going to blow up your car but 90% of the time it does cause drivability problems due to incorrect adjusment,poor designs,and less than optimal performance.If actually understand how a MAF system works this might be more clear.Why atmosperic BOV cuase less than optimal performance.. http://www.spdusa.com/blow-off_valves.htm
really??Like I said in my post, I have read the sticky and was wondering what everybody's opinion was on the subject; Maybe it was you that missed something...

i thought the sticky summed it all up quite nicely, which is why i assumed you didn't actually read it

I am of the opinion that the engine performance sticky is really really really in need of a huge overhaul. Has anyone actually looked at it lately? There's a poll about what's the best BOV and a thread with details to a BOV installation! There are also THREE threads on how to install a boost controller and 2 uber old threads about boost controllers that don't exactly discourage them. While there is some great information to be had if you are willing pick through it, the layout of the page and the age of some of the threads on it certainly doesn't make it easy and it's no wonder we get so many confused n00b posts these days. I voluneer to contribute to the renovation if anyone else thinks it's worth it.
