The proper way, not the ghetto way.

Hmmm i wonder how mine is done? It was installed before i bought the car.

I am wondering what the ghetto way might be? Is there another way to install this thing?

Ghetto way: Open hood, throw it at the engine and see if it finds where its supposed to go.



You can follow that up by dumping a cardboard box of turbochargers into your engine bay to see if that makes your car faster. :thumbup:

Umm really, is there a bad way to do it? The only other way I have ever seen it was with the bottom fed by the manifold (Boost) and the side vents to the intake. That’s the way SAAB does it but Audi uses the same style and boost pushes the bottom up.

That's not important really but I was just wondering if there was yet another way for this to go in. HKS style, vent to atmosphere?

the ghetto way is the one that doesn't work, if it works, it ain't ghetto in my book.

PS, works means for more than 2 months, working includes some reliability to me.

To be honest, I don't remember why I made the coment about "the ghetto way" but there was a good reason for it. I think just before finding this way to do it I found someone that did a brutal job or something, like they didn't use the right size vacuum line and hot glue gunned it on instead (which I'd like to point out fits both of Glenn's criteria but is still ghetto). In that light, I'd like to add as a key component of making an installation not ghetto is the capability of reversing it if necessary.

I don't know if you can open air them, but I don't see why not if you really wanted to, but then again, I'm pretty darn tired.

Cheers,

Cool....I guess hot glueing something is bad in a car...unless you are using JDM SupraTyte Glue.

Vent to air would be easy just plug the hole going into the intake and let the BOV sit in the same little pocket of tubing....it would sound f'd up though and your car would always look like it had a part loose....hummm sleeper trap I like it.

I have 2 bov's on mine..the Bosch and an HKS...what would be the +'s and -'s of removing the bosch? I heard that it will run more rich..is this true?

That is what I have heard but the effect will only be when coming off the gas. This is the way I understand it.

When you vent to atmosphere there is not enough air (creates a vacuum?) in your intake to balance out the gas that was dumped by the injectors. (Millisecond delay to stop gas flow). You will get a backfire under many load conditions.

When venting back into system it will balance the pressure (zero vac or boost) and more air will make it into the cylinders while still reducing lag. No back fire.

It depends on the PSI you are running...some high PSI, big turbo, tuners use 2 BOV's to release the pressure as fast as they can because they are moving more air by volume than one BOV can handle.

The benefits of removing your bosch recirc valve is you could give/sell it to me.

The problem with venting to atmosphere is that the EFI system has metered the air that you are dumping and adds fuel for it accordingly. Of course, since it doesn't reach the engine, you have a momentary rich condition with a potential for a backfire.

Mine popped like a ralley car when I was pushing it.

I don't know if you can open air them, but I don't see why not if you really wanted to

was trolling old threads when i saw the above post:
tried that on a friends car w/ the bosch. didn't work on a metered air system. the BOV will leak at idle, letting unmetered air into the system. to vent to atmosphere on a metered car, get a proper aftermarket atmospheric BOV or your idle quality will suck ass. friends car was constantly searching for the idle speed as the bov would not even leak consistantly.
