I was able to order off their website. Will give it a go when it comes in. My M2 boost flutters badly at WOT. Can even feel it throbbing acceleration when doing a pull 0-200km. Might be my elevation of 3200 feet also an issue. But I’ll try this to see if it helps the issue. I’m sure it’ll be a few weeks for shipping right now. I have logs and have posted them before in the forum. Will log it again after installation to see how it affects things.

Tempted by the Turbosmart but concerned about the servicing - Turbosmart recommend it every 6 months!!! (taken from here: https://www.turbosmart.com/news/look...ur-bov-or-bpv/) and there are posts on other marque's forums where people have had to service their Turbosmart DV to stop it sticking.
Given the major PITA it is to get at on the N55, this is not good. GFB reckon their DV+ gets enough oil for operation from the oil mist in the released air, but I have seen posts on other forums of people having sticking issues (but I believe that the majority are fine). I do wonder if a Turbosmart with a slightly heavier oil (e.g. like our engine oil at 0w30, or 0w40) would be thin enough for correct operation of the piston, but heavy enough to not need servicing very often (as the oil won't burn off). Anyone tried a heavy oil than Turbosmart's multi oil? |

"If the product you purchase requires servicing, it will be advised in the product manual." Their n55 dv instructions don't say anything about maintenance, so it must be fit and forget. |

So I got my Turbosmart mounted today on my M2. I lost nearly a 1/2 pint of blood in the process. It really is a tough job to get the 3 little bolts. Doesn’t help that I have fairly big arms, forearms and hands. I had to take many walks to reset and re-think my strategy. Followed the two vids on YouTube, they were a big help. I did it on my garage floor with ramps under the front wheels. Top bolt I actually turned from the top of car after I set the Allen key into the bolt from the bottom. It’s not a two beer job. This one deserves a full bottle of scotch.
Took it for test drive and it’s a lot louder than I had expected. No logs yet. But soon. |

On second thought it might be the combination with aluminum piping. |

I got the dual port vr11. Half vented to atmosphere and half into intake. Mine made whooshing turbine sounds before the bov just from the intake and solid piping. Now i get a very loud pressure release from the bov when I let off. Pssssshhhhhh.
The only Install issue I had is I could not position the valve with the plumb back vent facing the intake as the power wire would have squished up against that little curved oil line. Which would have made my hard job even harder. So I spun it around, like the guys in the Kies video, the power wire ended up pointing down towards me under the car. There is a channel all the way around to divert flow anyways. Also if anyone does this job, here is a really big helping hint on that top bolt: Insert your Allen key and extension from the top front, rest it on top of the front top water pump mount (you can see this from the top once water pump is removed, you’ll see the top bracket with the empty bolt hole from the top rad side). I had to move I take and some oil cooler lines out of the way. Anyways, rest it there on water pump bracket and then go back under car to feed it into the bolt head using your one finger that can just barely reach the bolt head. Use other hand to hold the extension end that is sticking out between rad and water pump mount. This is really tight to do with both hands Into the car and your head will be in no position to even see what you are doing. Use the force. It’s all by feel. |

When people are referring to logs, what logs are they looking for? Is it the boost pressure target vs actual comparison? I've been running BM3 stage 2 for a couple of months now and the turbosmart bov since last September and all is going well.
I've got some logs from BM3 but not sure which logs would be related to the BOV performance? |

Do a fresh log. I use 3rd gear on Dct with dsc full off, start logging at 2500rpm. And floor it all the way to redline in 4th. Then once you save log, I look at boost target vs actual. Also I look for knocks. So I usually shut off most of the lines when looking at logs as the graph is cluttered. I leave fuel on as well to ensure my pump is keeping up. Anyways that’s what I do, but I’m just a diy guy. Not a pro. Once you shut a bunch of lines off and simplify the chart then it makes more sense. Also stretching the chart timeline out helps Spread things out.

I just had my Turbosmart VR11 Plumb back installed today along with a Pure high flow inlet pipe. I was able to drive the car on the highway and on regular roads for about an hour after install. I am pretty much full bolt on with the exception of an upgraded turbo.
2018 M2 LCI Manual Trans BM3 Stage 2 93 oct AA Catless turbo back signature exhaust VRSF Charge pipe Eventuri V2 air intake Wagner EVO Comp 2 IC I was noticing some turbo lag with the above setup before installing the VR11 and after following this thread and a few older ones I thought it was worth a shot to see if it would help with responsiveness. There is definitely a change in the throttle responsiveness when applying throttle at various RPM's and even between shifts. I was setting myself up for disappointment and was pleasantly surprised at how the car delivers power after installing. I am assuming the VR11 is responsible for more of these changes than the inlet pipe, but as I said they were installed at the same time. FYI my stock DV didn't seem damaged in any way, but I am pretty sure it wasn't holding boost properly with the Stage 2 setup I am running. |
