Just curious, BOVs?

[TheHeggi]

So I've noticed that nobody so far is running a BOV? Is this merely because the maturity level of everyone here or do they cause issues with our systems? I'm assuming its not the latter, but who knows. I just remember I always dreamed of having an HKS when I got my first turbo car, but now that I have it...I just don't think it would be fitting, but a little part of me thinks it would still be cool haha. I just know it would get annoying after the first week and maybe a little overkill since I'm stock otherwise.

Forge makes a spacer that produces a loud BOV sound. However from my understanding, our car's MAF sensors rely on the diverter valve to recirculate air. Also, by "blowing off" air you are dropping the pressure so the turbo will take longer to spool up.

To get the psssshhh sound, all you really need is a new intake. Currently I have a forge diverter valve with a carbonio intake and that makes about as much sound as I would ever want (it gets annoying after a while). With that setup, if I'm accelerating under heavy boost and let off the gas, it makes a loud pssshhh sound. However, I can still accelerate normally and not get much, if any sound.

Edit: ^beat me to it

muahaha... I was hoping to be first on the scene with a quick response but SDquattrodriver beat me to it! I would have beat him if he typed more than 4 words!!! Bastard

lol, I was just gonna let it go. I don't really want the sound anymore, but I was just curious, and now that I've been searching since SDQuattro bashed me, I'm learned!

[Mr.Audi]

Let me add a question to his thread...

since forge adds the spacer to the application to make it vent into the atmosphere, will that cause any drivabity issues? running rich??? or cel's??

IAM sure they wouldnt put out something that would cause a the dv to throw a code.... would they? any an all answers would be great as i just purchased both(dv and spacer) and dont want any issues.

[Slo.Mo.Shun.]

The spacer sound horrible really, as I was just walking out of the parking building a guy on a GTI was making it go off, and it sounds really annoying and dull. The forge DV on the other hand makes a variety of noises that are much more enjoyable.

[jahciple]

but with just the forge dv, you won't really hear much of a sound right?
unless you have an intake to go with it? correct me if i'm wrong.

ive never heard the spacer... how does it compare to a typical bov? JUST wondering what annoying and dull would sound like. i cant search youtube at work, but does anyone know of any sound clips to listen to it?

like no other name brand bov on the market, the spacer sucks! it sounds like a long winded fart. pardon my pretty language, and as far as bov's go, you never want to atmospherically blow off air on a turbo system that is setup to recirculate, jsut a waste of air.. get some sort of aftermarket intake (build it yourself if u have to) and just get the forge dv, you will love it i promise

haha... yeah.. its a rare sight to see some of these new members actually seem to know what they're are doing or how to use a forum, unlike the majority of the noobs that just signed up...

[Mr.Audi]

i guess iam confused.... using the space then makes the dv "fully" atmospheric? and will make the car run like crap? I understand the need for recircing because that is what the computer is supposed to see.. or is looking for. Using the spacer will that be an issue or does it just sound like shit?

[viperdsa]

There are some threads of problems from people running the spacer and forge dv that they leak or something along those lines. Yes, it will make it fully atmosphereic forge has one for the transversly mounted 2.0T's that you can choose how much it will vent but it don't fit the A4.

In other words, when I was young I thought it was cool because I thought all the cool racers had it, then i grew up and realized i don't have to be a "cool" racer.

[Glassnpowder98]

Am I still a noob? At least give me credit and call me a semi noob... I've put some good quality work hours into this site!! All for nothing apparently

i guess i understand what your saying. Your saying that the "cool" noise is not so "cool" unless your an adolescent? I like the sound and iam 26 yrs old. Everyone has their preferences, especially when it comes to this that kind of thing. Now maybe the forge dv and spacer combo dont sound as pleasent as a "real" bov... but i will be the judge once it's installed.

just replace your airbox with a K&N filter and you'll get your BOV sound....

[Mr.Audi]

i have the gsg intake piping, and iam getting ready to find a good cone filter and heatshield combo for it. Then iam going to install the forge dv and spacer and if it dosent sound good i guess ill take the spacer out.

[turbo4s]

The spacer DV is alright. It does not hurt the car nor make the car run rich. I put it on my 2.0T A4 and my GLI. Got it from KMD Tuning for 65$. With software, Carbonio, AWE its loud when I spool it up. I know what some of you guys mean when your just driving around and you get the long faint pppsssshhhhh noise. overall its not bad. If I get sick of it, I just hop in my S4.

yea to bad i dont have an s4... i guess i could go get in the b6 usp!! yep that sounds good!

are you sure about this? how much difference does a drop in k&n filter make?

I have the forge dv with the spacer and with the carbonio it sounds nice im happy with it at low rpm it blows off in stages if that makes sense and at higher rpm its more of bite...i'll see if I can a video up

[eMacPaul]

The drop in filter doesn't do much... he was probably talking about a cone filter to replace the entire intake/air box setup.

[yung turbo]

i see no one mentioned the Forge SPLTTR VALVE. You just need the extra peice to fit the 2.0t.

[Mike@Forge]

I just want to clear up a few misconceptions in this thread.

The "digital" on/off nature to the discharge sound that is heard when our spacer is used is solely as a result of the fact that the valve system is electronically controlled, and remains open venting pressure until a digital signal abruptly closes it cutting off the sound.

The reason the spacer works without causing any issues, is because of the fact that we created a component that retains the OEM valve's electronic control features, and maintain that the ECU can control how the valve operates, so the sound that is heard is a byproduct of the factory valve's operation and not of anything that we do to change that.

Even when using an aftermarket intake, which are all less acoustically restrictive than the stock airbox and filter and don't muffle the sound as much, the same digital on/off "airbrake" or "long wided fart" sound results, but no one seems to complain about it as much because its not quite as loud as using the spacer.

When using our full replacement valve and the spacer together, the sound is still digital to a degree, but a little bit less so. Because of the fact that a mechanical valve is the main component of the setup, there is a little more of a "curve" to the sound, with a louder initial discharge and more of a tapering effect to the sound throughout the duration of the venting, but the electronic solenoid that controls the pressure/vacuum signals will still change rather abrubptly as the ECU sends the unmodified signals telling the valve to open or close.

Despite the MAF-based engine management system used on these engines, our spacer does NOT cause any issues whatsoever based on many months of development and testing prior to ever releasing the product as well as having sold thousands of units worldwide to be installed on numeorus applications from stock to heavily modified. The engine management is less sensitive to whether the discharged air is vented or recirculated than an older 1.8T engine for instance. We have extensively data logged and even dyno tested the unit and have found no evidence of any detrimental side effects whatsoever. No one else who seems to claim that the spacer causes problems has been able to provide us any with evidense of such issues either, so until that happens, I'll have to fervently declare that it can be used safely and we will continue to offer an unlimited lifetime warranty and moneyback guarantee on it.

[harryd14]

i am curious as to how difficult it is to remove the spacer and just run the Forge DV on its own. has anybody done this and how long does it take and is it very difficult?

[Vorsprung]

This should basically answer your question: http://www.034motorsport.com/product...9a87h4rpgjhs86

They make me laugh.

[vtracer20]

replace stock airbox + forge dv = bovish sound.

[Kevin2772]

I just have the Forge DV and that BOV sound that I have with the regular DV is gone. Not that I mind. My main point for going with the Forge DV was to stop cracking all my stock ones...
