Best BOV with the following qualities;

[BiD]

Hi all,

Just a newb question here. Which BOV would be the best bet that wont take away from reliability, that vents to the atmosphere. As all newbs, it would be nice to hear the BOV when I shift and such, although I have read on the forums that the stock BOV is not vented to the Atmosphere rather recirced. Will this mess with reliability?

Also, which BOV will require the least fabbing and assembly headache? And last parameter is cost, with all this in mind, which one will cost the least with the previous qualities being most Important?
I have a 96 GS-T. I am fully stock(except K&N replacement) and only plan on adding BOV, MBC and accurate boost gauge.

Thanks in advance for any help,

Big D

The best bang for the buck BOV is a 1G.

not hard to install,cheap and recirculates

So are you saying that venting could cause probs in the future.

I noticed your satement under your car, did you wrap it?

Lets just make this clear then, for the 10 millionth time (not being rude):

Any BOV that is vented to atmosphere WILL HURT PERFORMANCE.

There are a few exceptions to this rule. This includes ditching the factory MAF and moving to either a GM type MAF or a MAP sensor. This can be done via a MAFT or VPC/Standalone system, respectively.

Air is metered as it enters the intake pipe by the MAF, and fuel is added by the ECU according to that airflow reading (among other things). When the BOV/CBV opens, I releases some of that metered air. If that air is not returned to the intake stream, it is lost, but that fuel that was added for that lost air is still injected. This causes a rich condition which is more or less severe depending on the car. Some cars wont even idle properly with a vented BOV, while others SEEM like they arent losing performance, when it is a FACT that it will hurt you, maybe not much, but its still there.

As for "fabbing" the greddy type S will mount to the stock 1g BOV flange just by drilling 2 holes in it (flange).

Yes it can cause problems, probably the most asked question ever.


No it's not wrecked, It's just has a silve hood, stock side mirrors back on,and a primed 97 bumper.

I just noticed your in mesa,

PM me with your location. Always on the look-out for local dsms.

Keaka26, thanks, makes sense- I guess 1G BOV is the answer.

L2RTSIAWD- I see. Saturday drags are coming and Im thinkin about going on the 8th. Will you all be out there?

I have the Blitz BOV, but I also have a fuel pressure regulator. I don't know if this is why I don't get a crappy idle or crappy performance or not.

This venting into the atmosphere hurts performance is non-sense when it boils down to serious racing, yes it will hurt while driving around town. When you are in a serious race you don't let off the throttle, thus your BOV won't even go off until the end of the race, thus no return of air, no fuel/air mixture problems.

there might be a half dozen people on this board that have "serious race cars." Any weekend racer will only be hurt by venting, even if it doesn't seem like it.

So are you saying that you're not a serious racer if you let of the gas between shifts in a race? Im fairly certain most people dont do the "no lift to shift" stuff anyways.

My transmission is 13 years old, I think Im gonna give it a break during a race.

Edit:

Also, saying something like :

Doesnt really do wonders for your credibility. You stated your idle AND your performace is crap, and you dont know why. Not making yourself look too hot with that one, ace. Not to mention the use of a blitz BOV pretty much marks you are ricey. They are way too expensive, they dont bolt up like say a greddy or even a 1g bov, you cant recirculate them, and they sound stupid.
