Get rid of it. You can get the Pshhh sound with an intake or Forge DVs the same way (high RPM and letting go). At least the intake gives you some HP.

I agree.

I wouldn't install a BOV that's VTA period (on our cars, cars with stand-alones are a different story)....why not just get a DV that actually might HELP when running higher boost, such as race gas, meth injection, etc.?

Getting it JUST for the sound makes this sound like a honda tech thread....

e90AW335i · 08-15-2008, 09:19 AM

Another BOV thread.....

Short answer: Get rid of the BOV

Long answer: What did the 335i come stock with from the engineers at BMW? Why would you go an change that?

A standalone? How would that change anything? This car isn't MAF based, it runs fine if you vent the air. So, if your stock DV's are leaking, and you put in a BOV that can run higher boost, that wouldn't help? I understand that many people hate the sound of a BOV, which is fine, but I just don't get how most people can't see upgraded DV's and BOV's as performing the same function a different way.

If they want their cars to pass emissions they don't have a choice.

I'm not saying that I see the point of having a BOV on an auto though.

Another BOV thread indeed!

There are no problems running a BOV on these engines as they do not use a mass air flow sensor (like most production turbo cars).

Why didn't BMW install VTA BOV's? Probably because they can't have air discharging into the atmosphere on a production, road-going vehicle. Bad for emissions, and most non-enthusiasts would complain about the noise.

Or because it is a BMW and not a turboed civic....

Funny because I thought that piggybacks were only for turbo'd civics as well.

Turkishexpress · 08-15-2008, 10:55 AM

Wait the the 335 is map based! Good for BMW. Finally someone with some common sense. I hated the problems the maf sensor gave with the Evo...

Ah, was under the impression that this car was maf-based...then yes, disregard my comment about the stand-alone.

I don't hate the sound of it, but if your stock dv is working fine when you're running stock boost, then my personal opinion that changing it soley for the sake of sound is dumb...but if you're running higher boost, or suffering a leak for some reason, then it serves a purpose.

Nicely done sir.....

You have step. You can hear it everytime you shift.. if your in step.

People like different things, some go for BOV or some go for upgraded forge's.

It's really a personal thing. I run auto and have the AA Bov.... I drive step mostly.. so I hear most everytime. I'll also be running an the new AFE intake... (awaiting) and will be getting horsepower out of that.... so either upgraded dv's or a bov do the same thing pretty much since we have MAF.

sorry... but if you're right in saying that our 335i don't have a mass air flow sensor, that means that there is no issue using an oil-impregnated air filter (which historically deposits oil on a MAF sensor over time, causing a degredation in performance...) Am I correct ???

Correct.

Using pre-oiled filters right out of the box is fine. Some people tend to apply too much oil to the filter in the cleaning process. This can cause MAF issues.

all due respect to BMW engineers, but this board is all about making improvements to their efforts, no?

Correct, but than upgrade to Forge DV not some ricer BOV...IMO.

Now lets get to the next question. Would they try to void your warranty for having an aftermarket uicp with a bov?

You prolly should return ur piggy back ECU if this was the case...

Yes having a BOV installed and something goes wrong with your turbo, they will likely hold you liable for it. Just return it back to stock if you need to take it in.

I like the sound of BOV, i think it's natural on a turbo'ed car...although i don't have mine on anymore i still love that sound

Those that say, "ZOMG, don't put a BOV on a precious 3 series"

it's just a car, get over yourself...if this was a Ferrari or Lambo then maybe you can use that statement to justify
