Im in the process of getting all the parts together for my turbo swap and came to the point of buying a bov. My friend had his stock 1.8T bov lying around and i was wondering if it would work ok and not cause any problems as long as i plumb it like stock.

*edit: Not planing on running much higher than stock boost.

should run just fine...how much boost does a stock 1.8t run? as long as your not higher than that...just run it like the normal BOV runs...

Ok well the 1.8t runs about 6-7psi stock but my friend was running this bov on about 20psi for a week or so and it held fine. So i dont think that the stock turbo on a 13bt should pose a threat.

NO! NO! NO! that is not a bov..its called a Diverter valve..it will not run right, and it will sound like the typical vdub that is like short little *PINK* I wouldnt do it.

what the diff. between a diverter valve and a bov on an operation stand point? If it free and works i wouldn't care if played the god father theme when i let off the gas.

i found this and it seems that a Diverter valve is just a fancy name for a recirculated BOV. So as long as our cars use a recirculated BOV which im pretty sure it does then there shouldn't be a problem right?
Here is the article:

Blow-Off vs. Diverter Valve?
I have a question maybe you can help me with. I noticed a lot of German cars (Audi, VW, Porsche, etc.) that are turbocharged have diverter valves as opposed to blow-off valves. I understand that a diverter valve "diverts the excess boost" back to the intake tract as opposed to blowing it off to the air like a blow off valve. Because of this the diverter valve is fairly quiet, letting out only a slight "whoosh.” Is that the only difference or are there any specific performance benefits to either one? Currently I have a 2000 Audi TT Quattro, and yes I do have an aftermarket DV (Stratmosphere), but I was just wondering.

As you mentioned, the main purpose of either the diverter valve or blow-off valve is to let off excess boost. The primary reason that Audi, VW and Porsche use a diverter valve is due to their use of the Bosch Motronic engine management system and a Mass Air Flow sensor. It’s programmed to expect the “extra air” which is rerouted back into the intake tract and adjusts the air/fuel mixture based upon this. Therefore it’s simply the design of the system and there is no real performance benefit to one or the other.

anyone have any opinions on if it will work?

Well, I own a 1.8T and we HAVE to have a diverter valve , and you won't really get any noise out of it.

You could have the bottom end vent into the atmosphere if you would like, its up to you, but if you're going after that sound,,,,buy a BOV.


and mine doesnt go *PINK*, it goes shhhhhh

It's a recirculated valve so it's output will have to be plumbed back into the intake tract after the AFM. Most recirculating BOVs leak a little at idle. But as long as it will hold the pressure, it will work fine.

ya thats what i figured. As long as i recirc it, It should be ok.
Good.

It works, Im using one on my car...it doesnt make any sound really..sometimes it makes a really sweet sound when you really knock the **** outta it, like 8-9lbs but other then that, you dont get much of a sound...

driftin8ez

ok cool. Good to here someone is actually using it with sucess.
