Stock BOV Question

[Spooled238]

Hey i wanna keep my stock bov, i was just wondering, if i take the recirc hose off and keep it open, would it just run rich?, is there any specific reasons that i shouldnt?, and along with that, what do i do with the other part of the hose where the bov recirc hose connects?, there is a small 16g turbo on it if that is any kinda help, thanx

2. Loud BOVs (the pssshhhhh sound between shifts)
The second most common question is, "how do I make my BOV louder?". Most of us DSMers will cringe when we hear this question. The fact is, a louder BOV on these cars will conflict with vehicle performance. In order to make a BOV loud, you have to vent to the atmosphere (as opposed to back into the intake, like our cars do from the factory), releasing the excess air instead of routing it back into your turbo system. The problem with this, is that your ECU has already accounted for this "excess air" and adjusts fuel curves accordingly. If it's not in the system anymore, the ECU is compensating incorrectly. This means that the car will not run the way it's supposed to. It may idle poorly, or it may not be noticable - but it will have a negative effect, even if you can't feel it (the logger will prove it). In any event, it is not the best thing to do if you are serious about making maximum performance. And if you are more interested in making your car sound "furious" and not making it "fast", expect a good deal of heckling, as this is a performance community.
