Best upgraded diverter valve N55 ?
Seen load of people run the Go Faster Bits DV+ but read it needs some maintenance?
A few other state the Turbosmart one is best but I cant seem to find one that states it fits and N55 335i. What do people run for an upgrade DV ? |

Turbosmart is certainly the more popular one for my customers

Been running GFB DV+ for +5 years. Zero maintenance done, but then again - the N55 is self lubricating on the external components also

Sorry for the question if it's dumb but what is the advantage or gain from upgrading the diverter valve?

It doesn't necessarily provide any direct benefit if your stock DV is doing its job. Some people report improved throttle response and/or lower WGDC. The basic idea is that the upgraded DV can respond quicker (throttle response) and hold boost better (WGDC) than the OEM one. Keep in mind the OEM one was really only designed to work in the 7-11 psi range and people are pushing as high as ~20 psi on stock turbo. I am still on stock DV with no issues running up to about 17psi but i may still do the turbosmart at some point and try to quantitatively test.

Would the DV to atmosphere version cause it to run rich as its expecting meter air back in the system? Or not an issue on a modern car where the DME can respond quickly ?
Just wondering if I should get the replumb version or the "dual port" which does both |

The working theory is that the DME can respond fast enough. A few people have reported running it without issue. This used to be a problem on turbo cars from the 90s, and my 3000gt used to stall if you did a WOT pull and went immediately to neutral when it had a VTA BOV (stock was reicirc). Seems to be a nonissue on modern cars though. The dual port will be much louder FYI.

I have the plumback and it is quieter than stock even with my bms intake.
With stock and the intake I would get the swoosh sound. Now its barely perceivable. |

If you just want the swoosh noise, I would try an intake 1st. They are pretty cheap and much MUCH easier to install.
Think 6 minutes vs 6hrs of anger and frustration. |

Thing is I've read open cone will cause heatsoak, CEL lights, less performance is a high price for noise. Any have experience with any of the above?

Not all cause CELs. For example CTS does not, because it has a properly designed MAF housing. They don't really cause "less performance". Any increase is debatable, but unless you have a really poorly designed intake it shouldnt make your car slower. It may change your throttle response and drivability characteristics. Read my intake thread here as it basically answers all these questions and more: https://f30.bimmerpost.com/forums/sh....php?t=1765289 |
