Good BOV

[Halon]

What's your goals, and what car is it going on? A stock 1G bov is cheap and goes a long way.

What is a "crushed 1g BOV"?
A stock 1G DSM BOV put in a vice and crushed down a bit. You can do the same thing to an Evo IX BOV. Basically, it helps them hold a bit more boost but at the expense of flutter.

You aren't going to want a 1G BOV on an Evo, even crushed they leak before a stock IX BOV does.

Well i'm not running that much boost, so the crushed part kinda seems a bit extreme at this point... Or am I missing the concept?

[Kracka]

Unless you're running over 30 psi there is no point in crushing the IX BOV.

sweet sounds good! thanks for the info!

So, say I had a 1g does a evo 9 bov have the same flange as the stock bov? I'm running a 2g Mas still so I want to recirculate the air still, but I will be running just over 30psi... Any other recommendations?

Evo IX will work for you, I have one if you want to buy it.

[CarPsyco84]

Yeah, how much?
