Installing BOV

[cre]

It's not complicated at all, I didn't mean to give that impression... you just want to be sure that the vacuum signal has enough volume to open at least one of the valves with as little delay as possible. It's like launching a pee from a single straw versus trying to blow 4 the same distance from 4 straws in your mouth at the same time.... all four probably won't make it past your feet and you're going to have to blow a lot harder.... so, to avoid that trouble you either want one of the valves to open with a much lighter vacuum signal or you'll want to supply each with it's own line from the intake plenum. Not a very big deal.

ohhhhhhhhh.......I see. is it pretty obvious on how to adjust the spring? or is it hidden somewhere deep within that monster of an engine. lol

Please do not take exception to this request, because it is not specific to just your questions and answers, and is not directed at you.... BUT!
Forum all over the internet would be so much more informative in general if the participants would use full word terminology rather that anachronisms or abbreviations. I realize that cryptic writing has become the internet standard, but it sure limits the sharing of knowledge.

Thanks You Very Much!

...i'm not trying to be mean rude or crude, but this fourm in particular hasnt used hard abbreviations and in particular this is a research-type topic. meaning i'm seeking information, and people are trying to help me. so if your not willing to go google a few terms that you dont know or look at the fourm that explains common abbreviations i think your in the wrong place.

Ok, that's enough of that, There's a thread about this in the off-topic section. If anyone feels the need to discuss it further, please do so there.... and please keep it civil.

hey cre, now back on topic..
i just read on another page that having two pressure release systems is actually a good thing because you can adjust the spring on the stock to handle small pressure and the (lets just say HKS because thats what i'm getting) hks one tighter for the heavier boost levels. is this true? or only for cars that boost ALOT? and i also read that you shouldnt mess with the spring rate of an HKS.

Hey bro if you do this install of an aftermarket bov with the (whooosh) sound haha, can you post a pic or two on how it turned out??

That's what I was talking about. It's not needed for low boost levels... you really don't need to worry about the stock BOV not flowing enough air if you're still running a stock BOV. The only people who I know that run that way that aren't pushing a lot of boost do it for stealth purposes.

I must say, the stock BPV on my MR2 is LOUD... so's the Bosch that's on my former Supra... they've both got much larger apertures.

ohhhhhhhh. ok. lol now i get it

and my stock one is kind of weird. sometimes it gives the whosh loud and how i like it. but most of the time its almost non-exsistent. the sound of the engine overpowers it
