blow off valve on a 2000 A6 2.7t

[master_popoy]

need advice good or bad newbie with Audi

[BeOhBe]

Saw your post in the exhaust thread, but I'll answer it for you here. Bad idea. Tell your friend(s) that Audi's are already headturners, without the ricer bov sound. Just get 710N's and call it a day.

Basically if you ask that you need to sell the Audi and get a Neon SRT4. With that being said, we just installed the 034 Motorsports Forged Diverter Valves on mine and it gives off a small blow-off valve sound. Nothing super loud like the normal ones, but loud enough I could hear it in the car with the windows up.

[Dr. Funk]

Ew to this question

[DCandDGK]

Easiest way to use a BOV is to sell your Audi and buy a ricer. Problem solved.

[master_popoy]

So Vinchenzo51, its not ok to ask someone else idea? this is a forum to know more about Audi's and stuff. 2 heads is better than one right?. im asking different people on their perspective. maybe you answer my question before, but im not satisfied for just one answer.

maybe this is a EW question for you Dr Funk, but for us newbie who wants to explore, its a must for us to understand.

[DoomedHatch]

The car is designed to have a Diverter valve. it will have some running issues if it gets a BOV. I had my 710N's Vented while it sounded good. drivability went down to me.

So I just ordered Forge Splitters ( Diverts and splits off for a BOV)

I personally LOVE BOVS I don't see how a BOV makes anything a ricer as someone stated before.

If your gonna say a BOV is a ricer, tell that to all the EVO, Subi,Supra,240,Skyline guys. yeah pretty sure they will all take offence and they will give you a little piece of there mind.
What I think is a ricer, is a bone stock single cam motor, with a 3in exhaust with a huge ubly body kit that's not painted to match the car. and interior is spray painted to match outside of the car.

Anyway, just cuz some guys don't like it, do some research and get the right now. convert the car over to speed density and I am sure youll never have a issue with the BOV.

On an Audi, a bov is unnecessary. That's why it is ricer. That's the definition of ricer as I know it. And I drove a 240 for years.

But yes, the OP should most definitely do some research. There's reams of it here and other sites.

Best of luck with the speed density conversion.

Really Something unnecessary is considered ricer? If that's the point your gonna try to make 90%+ on any car fourm would be considered ricers.
Air Bags, I find completely unnecessary I don't think there ricers for doing it.
Different Color rims ex. White,green,gold,bronze (not ricer but not needed)
Intake, exhaust, Turbo Upgrades, manual conversions, switching interiors really all of it can be considered unnecessary. going for the OME+ look?

Your definition of unnecessary of ricer might be skewed.

A BOV, as it doesn't have to have function for the car. some people like it. I like it, Its something that really accents the car. it makes peoples heads turn( yes audies do that already)
It means you have something else done to the car then maybe a HID conversion or a drop like everyone and there mom does.

I had a ricer car when I first got in to the scene, But a few weeks after I wrecked it (only had it for 6months) I built some fast as fuck cars, and all had BOV's
So maybe my 500+WHP AWD cars were ricers to you. but I guarantee that they would have beat the wheels off a good portion of the community.

As OP he is asking for advice, and if you go and pound into his head that a BOV is a ricer then when will he learn anything about it?

Now there are BOV's out there I would say are bad quality and the noise they make is horrible, Greddy RS one for me sounds just terrible, I hate the HKS SSQV BOV as well.
I Like Forge Products, and Synapsiss, Audis OEM Diverter valves some are garbage, the 710N's is a good OEM upgrade.

Forge has splitters, that are both DV, and BOV. There are lots of companies and good proucts out there that people will consider "RICER" maybe cuz they come from a china made area. I have had some very expensive stuff I imported from Japan, and it was most def not ricer.

Also to the OP, a BOV and DV both do the EXACT same thing! You can argue allday all night a DV is better then a BOV. but FACT is they do the same exact thing. Cap of one end and the DV becomes a BOV.

On the Audi The air Is monitored when it goes it, so the car knows how much are is there, and how much its pulling in, so when you have a BOV, it has the air measured already for fuel trims and all of a sudden it will not have that air in there as it will be vented out and it would make the car run a little weird.

I am sure there is a way to tune it for a BOV to where it would have less or more fuel during the venting process and it would run alright.

Converting to speed density wouldn't be too bad. and I am sure there are people out there that do it.
Eliminate the MAF, get a MAP sensor and a air temp sensor, wire it in, and tune for it. But that's going way above just wanting to run a BOV. your getting into serious power there.

No, not "something" generalized like air bags, new wheels, or bov's, but rather "something" very specific. Like bov's on an Audi. Ricer as fuck. Like I said at the top, get 710n's... and call it a day.

[BeOhBe]

710n's seen here:



Save your money for those ricer bags and ricer wheels and ricer tint and ricer spoiler/lip and maybe some things that actually make your car mo faster...

[DoomedHatch]

Guy do you even know how a turbo car works? or even anything about a turboed car besides the fact that you owned a 240 and a audi that's turboed now. which I only assume were both turboed.

Your saying its ricer as fuck. Do you even know what a ricer is? look up the term, Im sure urban dictionary can help you out.

Now you posted a video, IDK what its about, only watched 3.27mins of it, and yes they showed a 710N whooptido! but I stopped watching after the guy stated It can improve throttle response and help keep a certain amount of pressure to help spool the turbo.
he also mentions it should not affect the preformace of the tune, as its doing exactly what is intended to do, open valve when throttle is closed to relive pressure out of the charge pipe.

Now you said "make your car mo faster"... Now with what was stated above ^ Pretty sure that qualifies for making you car hella mo faster! and what ever you have to say past this point is invalid. as your vid proved my point and not yours.

Anyway, to the OP. do what every makes you happy with your car, its YOUR project not someone elses. a Properly set up BOV is just as good as a OEM DV. or anything else you can put on your car to make it MO faster.

[BeOhBe]

Guy do you even know how a turbo car works?

Ha!
Yes, I know precisely how a turbo car works. You push the gas pedal, the gremlins food hatch opens, skittles pour out, and BAM! Mo faster.

Fucking. Relax.

My point is, a properly setup BOV is only as good as oem dv's. Doesn't it seem kind of ricey to do an engine mod for little to no performance gain?

Oh, and I looked up "ricer" on urban dictionary, but there was just a photo of a 2.7t engine bay with some BOV's in it.

Your knowledge of how a turbo works impresses me!

I agree sometimes a BOV can be a bad upgrade esp. if you have other mods that can be done instead of it that you could gain power/ reliability from.
BUT, what if you have a leaking OEM DV? don't want to go stock spend and invest what would be the OEM price of it towards a good reliable one? Good mod there.

I don't know why the OP wants a BOV, but if he wants it for the Noise/look/ turbo feel for the car, I say go for it. its his project, his money and he can do what ever he wants as long as he is happy with the decisions he makes for it, and as long as he likes it, as ultimately he is the one that has to deal with it on a EVERYDAY basis.

I have done mods to previous projects that were not liked, people thought were dumb. But I liked the decisions I made. and I had lots of fun with it everyday.

[PipeHitter808]

All of you are arguing about something that really is not that important. You wanna do a BOV cool do it. You wanna do DV's cool do it. Put up your dyno results or STFU.

[NuGGet_PuFFer]

Hey now there's useful stuff in here, for example, I now know how a turbo car works. And to think all this time all I needed were more skittles...smh

Yes it is ricey when it is on an Audi...240s, Supras, STIs, SRT4's, EVOs, etc are expected to have them. The same with BMW Angel Eyes...look great on a BMW, but is ricey as shit on an Audi. Basically what we are saying is if you want a BOV or the BOV sound, you f'd up and bought the wrong car. My A6 was dyno'ing 571hp on 710's and my current setup will be closer to 700hp. I upgraded to the Forged for shits and giggles...the 710's would of been fine. So there is no performance reason to have one on an Audi. IMO it is the same with putting a FMIC on a S4 or A6. People do it for the look, but it actually decreases performance versus the dual side mounts. In the end do what you want, it is your car and money. Just know that when the rest of us are looking at your car, we are making fun of it not admiring it.

[DoomedHatch]

Everyone is entitled to there own opinion. And what's ricey to someone might be really cool to someone else. I like the sound a BOV makes, coming from previous cars its just something I always liked. FMIC I also like the look of, and I think a good set up with a FMIC wouldn't be too ricey, but that's my opinion. The 710s as good as they are, I have a set on my car right now. I just don't like them. but that's me. good OEM product, I got for a steal. I also have a FMIC, and Forge splitters, I must be the riceryiest person on this form according to you guys.

But either way. everyone has there own likes/tasets, that's why I don't bash on people who have stuff that's not popular to people.

The halo Headlights look fantastic on a BMW, I wouldn't be able to run them on my Allroad, Aswith the DLR light, I love the look of them on the new Audis, but I couldn't run a set on the older ones.

DRL's look great if done correctly. I am actually starting over with mine now with a new front end.

IMO, I am no a fan. and I don't like the German license plate either.

[Vinchenzo51]

Useless thread is useless

[DCandDGK]

Here's on for you DoomedHatch…Do you know the purpose of the DV? Where does that DIVERTED or recirculated air go? If you know where the air goes and why, then you should understand why BOVs are shit on Audis. There is a reason they used DVs from the factory and not BOVs.

[OGBULLYLOCDAWG]

Man.. y'all let that man run himself some blow off valves.

Just don't respond to his thread when he comes back asking about the CEL and misfiring.

[DoomedHatch]

The Diverted air goes back into the intake, after the MAF Sensor, as it is already measured air for the car and is being put back into the system. The air is already measure, and the fuel trim is adjusted to match the air already in the car.

yes there is a reason that DVs are used, but there shouldn't be any reason not to use one if its set up correctly. I am positive you can tune for it. and it would not have any affect on the car.
Lets say there is a MPG loss, its not gonna be a lot. maybe .3mpg TOPS? if your gonna complain about that much loss, maybe modding cars isn't for you.

If BOV's are SOOO bad for a car why does everyone sell them for audis? If BOVs in general on cars that are not speed density are SOO bad how come so many car companies/ race teams/ anyone that mods a car runs one?

Yes, Audi is a finnicy bitch when it comes to little things being modded and they are SOOO fucking rediclious on all trims being close or you get CEL and god knows what else. But As anything there is a way to put it on, and not complain about it all.

Please please please for the love of God, sell your Audi.

You sell yours, yours has more rice on it with the Garbage Euro plate on it then mine does. Also is that halo Headlights ?

[Furly]

Basically if you ask that you need to sell the Audi and get a Neon SRT4.

Nothing super loud like the normal ones, but loud enough I could hear it in the car with the windows up.

the 034 DV is not forged, its aluminum, and its a $5 valve that they charge $100 for. and its a replica of the forgeDV but its from china.
if you're going to buy a DV get the forge 007, or whatever works for your model. the plastic ones suck and break all the time. the forge dv is serviceable , meaning you just take it apart and clean it every few months and you're good for the life of the car.

[Dr. Funk]

What is a diverter valve? Should I change them with my oil?

[NuGGet_PuFFer]

What is a diverter valve? Should I change them with my oil?

It is a valve of life, designed by ze Germans, that usually diverts ricers away from Audi's to Hondas, SRT-4's, Cobalt SS's, and so forth. Somehow that guy ^ slipped through, maybe there's a new revision out?

[master_popoy]

what is the 710N? is this a DV for another car? like Audi TT?

[DynamicSound]

You sell yours, yours has more rice on it with the Garbage Euro plate on it then mine does. Also is that halo Headlights ?

Didn't know a euro plate was ricey, I still have it, but doesn't say twin turbo. And those are factory Hella headlights with cleared corners, nice try. Now sell your shit.

Majority of products are from China so that doesn't mean anything. I know plenty of people running them with zero issues. Plus if they go out, it is a pretty cheap item to replace...rather buy a brand new one than clean out the other one every few months. Not to mention tons of people believe they are the same ones, just unbranded for 034motorsports same with a lot of the other products they sell.

[DoomedHatch]

You sound like a complete Idiot.

1. A plate other then a factory plate on the front is pretty ricey, Doesn't have to be a JDM car to make it ricey. Yours says something gay. \
2. I am pretty sure every ricer in the history of ricers has put "clear corners" in there car.

But I wont judge you by how you modify your car as you so blatantly judge others. Good luck with your modding.Hope it all works out with you with your vast knowlage of ricers, and how everything functions.

DoomedHatch Out On this subject.

Oh PS> Ill update you all on as soon as I have my ForgeSplitters put on my car and how awesome and amazing they sounds. ( DyanamicSound, Ill exclude you on this as it is too ricey for your Taste.)

[Vinchenzo51]

what is the 710N? is this a DV for another car? like Audi TT?

This is the best question you've asked so far. Therefore it will be answered.

The 710N is the revision of DV for the Audi TT 225. The revised DV is better equipped to handle extra boost. Its also a cheap OEM replacement for failing stock DV's. B5S4 folks run these same 710N's in 500+ HP applications without batting an eye.

Now, the negatives to 710N's. They are plastic, so they have the potential to get cracked due to heat, age, and wear (although not often enough to make it a big deal). The big deal for me, is they aren't serviceable. They are in a plastic shell that cannot be opened.

Most billet DV's not only have less chance to crack, but can usually be opened, cleaned, and regreased. Since they can be opened, you also have the option to change the springs inside based on your specific setup.
