blow-off valve?

yelljack · 06-30-2003, 10:59 PM

I understand what it does but is it worth it? Any significant performance increase? If so what kind? Acceleration, top end...

ps. I don't mind the flames

no performance increase, just a nice sound. However on some cars the stock BOV leaks and they need a stronger one to prevent leaking. In that case it could have a very big performance affect (that is if ## leaking boost pressure).

yeah after-market BOVs help performance since they hold more boost over the stock BOV, however if u dont hav a boost control and ## just runnin the stck boost i dont think it will make that much of a difference

haha, that thing is a POS, reminds me of some1 at my school who put a BOV on his corvette. sounded 2 ricey to b true

BOV's help to maintain boost.
I would get one.

wags528 · 07-03-2003, 07:31 AM

i heard that aftermarket BOV's are not good for the car . . ? is this false information that people tell me? . . .

Tut4u2 · 07-03-2003, 07:40 AM

i kno that on DSMs aftermarket BOVs that vent to the atmosphere r bad cause the car will get idling problems, i dont kno bout WRXs though.
overall however, theres nothin rong with aftermarket BOVs. they hold more boost, and prevent any leakin. i guess some ppl might think they are bad cause the ngine is gettin more boost, but i always take that as a plus

kylo19 · 07-08-2003, 05:33 PM

lol, dont listen to this guy i have the hks and its 100 percent vented to the atmosphere and theres no idle problems. I also have 2 friends with dsm's who also have the hks and they have no promlems. Get what evers durable and get what u like . buying a BOV is basiccaly which sound u like. Just my 2 cents.......

There you go man, that post has some good information. And to kylo, on DSMs BOVs that vent to the atmosphe might cause idling problems, but not always.

wags528 · 07-09-2003, 01:20 PM

i just heard from some people that aftermarket ones hurt the engine and turbo . . i figured they didn't know what they were talking about, and wanted to hear from the wrw owners . . id get one, just cause i love to hear that sound between shifts . .

but giving the engine more boost (without upgrading other components first) is bad isn't it?

kylo19 · 07-09-2003, 01:25 PM

Sorry tut4u2, diddnt mean to say it like that but yea there is a possibility that it can cause idleing problems. Its just that from the people that i know who all have ssqv's (100% vent) dont have problems.

Yes is it. However, you generally change your BOV after you have changed your IC pipes, and other components.
