I love the sound of the atmospheric BOV but as i understand the VW has an internal BOV that doesnt work the same. Is there any way to get the atmospheric BOV (the one that makes the PSHHHHH sound) and not throw 100 different check engine lights? Any help would be great. Ive found this one http://www.ecstuning.com/stage/edpd...&submodel=&category=Engine&subcategory=Intake
but im just wondering if anyone has actually attempted this change and how it worked because there is a disclaimer that it may not function exactly as before and i dont wanna risk screwing up the car by doing it.

on the switchable Forge valve ... i see it has 3 settings...loud, intermediate and quiet ... the loud one vents everything atmospherically, this sounds like its good to eliminate turbo shock ( as they call it ) the intermediate is partial atmospheric and partial recirculation, and finally the quiet is total recirculation, which im assuming is what happens in the stock configuration of the motor???

My question is, how does each of these settings affect performance? does the loud setting have the most benefits in the form of less turbo strain? does the quiet setting put more of a strain than the stock configuration? is it best to run this intermediate to get recirculation and reduce turbo strain by venting atmospherically?

Engine afficianado's please chime in?

Thanks - TOE

The stock turbo is a recirc setup so there would be no strain on anything. I'm not too sure about the benefits except that having an atmospheric BOV is better for faster spooling between shifts. I'd run it in full atmospheric if I was geting one. Oh and yes the Neuspeed CAI really enhances the sound of the stock wastegate, I love it.

hey im glad somebody has posted on the BOV, as ive been after one for some time but dont know which is best...

after doing some research i guess the forge atmos is the best as its made specialy for the vw 2.0 t engine.

i suppose it will help the turbo but most people say it makes the turbo slower without remapping the ecu it aint worth having.?????

If you a running the engine stock, the stock diverter valve is fine. However, once you upgrade the ECU/Maps/increase boost levels, you do increase the (slight) risk of tearing the diaphragm. The B series valve used on the original MkV 2.0TSFI is weaker than the newer C series valve used on the 2007 and up.

There is some debate over the Forge valve, (in particular response times and that the Forge has to be cleaned and serviced) being a piston valve vs the stock diaphragm valve. You want to consider the one made specifically for the 2.0TFSI and keep it in the recirculation(Diverter Valve) configuration for best operation w/o a check engine light. :)

Dragon, you rule... Thanks for the info, that is the question i wanted answered.

One of these days my kids will get a job and start buying ME stuff ( like mods and ground effect kits and stuff - lol )

Every time i get a grand or two saved up for toys the kids need dental work or a new ipod or money for school field trips or a skateboard or bicycles or....or....or

Just wanted to go off what Dragon said because I remember this discussion on another thread about 7 months back. Anyways, I remember the general consensus being that you definitely want to stick to the recirculating valve as well. I know there's a way more detailed thread about this somewhere, but I'm just too lazy to find it.

I've heard really good things about the Neuspeed. I'll probably end up getting one in the next few weeks. The Carbonio is sweet because you don't have to lose the stock engine cover, but I've haven't heard people raving about the performance or sound gains as much as the larger Evoms or Neuspeed intakes.

Dragon - are you still able to drive pretty confidently in wet weather with the race extension? Did it bring noticeable gains over just the regular P-Flo?
