Installing BOV

[cre]

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

[supra_rulz]

ok, well i got it today and installed it right away.

anyways so i actually pulled it off and installed it. it works great..........except for the one problem i knew was comming. the stalling. lol it kinda sucked because i was testing it and my car stalled right next to this really hot chick, i waited till she pulled away to start my car lol

so my question now is, for the resurculation thing, do i just need to get a hose and connect the outlet of the BOV to the acordion bend where the old one went?

[supra_rulz]

another question. lol

now that i have a BOV, shouldnt the boost gauge read 0 when i'm not on the gas?

EDIT:
ANOTHER question. will getting a MAF instead of AFM help at all? and will rasing the idle rpm be a shor-term fix?

Nope. Your turbo isn't spinning fast enough at idle to counteract the vacuum that your engine creates, so you should be reading a few in/Hg (or -psi depending on your boost gauge) at idle.
