Installing BOV

[cre]

Yes, you can run them in sequence. You'll need to check the opening spring rates so you know which will open first, you definitely want one to open a bit before the other to ensure that (if they're sharing the same vac source) there is no latency introduced.

You say you like the Woosh,... so why are you looking to change? And yes, you can run two OEM style or Bosh style BPV too... supply them with vacuum from different location is my recommendation there.

Unless you're running VERY high boot and having issues with compressor surge there's really no reason to run dual unless you're running a BPV and a BOV so you can get that uber cool, ricer x-treme chirping going on... but the woosh will be significantly less too.

ok. i donno, i cant make up my mind. now it sounds like i should just remove the old one just to make sure that there is no delay between the two.

and....i'm kind of confused. i'm adding one because i only have a stock one and it doesnt make the whosh noise as loud as i'd like it to.

and no, since i'm just starting to build it up, i'm running stock boost even though the previous owner was running like...12-14psi with almost stock everything

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
