S63 Turbosmart BOV upgrade w/OEM chargepipe

[frankenm]

Found this BOV upgrade is available for the s63 engine - this will hook right up as a replacement for the OEM diverter valve

Part number is TS-0223-1292

https://www.turbosmart.com/product/b...lumb-back-vr9/

People are using the VR11 on the M2 with success

I have turbosmart BOV/s right now but it is a custom setup might try these for use with the OEM chargeipe

They are a dual port so it vents to atmosphere and back into the turbo intake so shouldn’t throw a CEL but I haven’t tried it so can’t confirm

Anyone looking to upgrade their diverter valve this is besides the DV+ the only other option so far for OEM fit

Ty for the link and very cool to know these are out there.

Looks very tempting!

When my diverters start having issues I'll get these.

$230 each! Dayum, that is very expensive but hey if they are more robust than the factory ones......once my factory ones start going bad i might get these.

OP if you go ahead and get these please post pics and let us know if you get a CEL or not. Thank you.

I believe they are just back in stock

I've been wondering the same thing. I put one on my N55 1series and its holding up really well. I know the air is metered by the MAF's on the X5M, but was wondering if enough is bypassed to not run rich. I contacted Velos to see if these would be possible to run with or without there tune and if the rich condition could be tuned out. If they weren't so pricey I would bite the bullet but at about $500 a pair IDK. More to come...

I put together my own chargepipe that can be either recirculated or vented to atmosphere - I never had a cel because of it

I originally did all this to upgrade to TU turbos and just happened to find these

Just so happens you can use the same vacuum actuator for the wastegates as an actuator for a vacuum operated BOV and use any aftermarket available .... same concept they are doing. I use one of their vacuum BOV’s for my custom setup this one is more just plug and play with OEM chargepipes

Bro do you have a exhaust video of how your TU turbos and manifold sound on the s63 x5m?

Yes - I have needed to upload this -

Exactly what upgrade does this have over the OEM diverter valve?

It makes it go woooooooooossssshh ..... also serviceable and built to last hopefully.

I added a link in my last post to a sound clip I took with their kompact series BOV's at full atmospheric vent that I used in my setup for TU turbos ... I enjoy them they make cool noises

If you consider added turbo lag, possible (low chance) check engine lights, and pffft noises on shifts/throttle lift an upgrade, this is the product for you. This is not a performance upgrade, this is a noises/matter of taste upgrade. As you can tell I'm not a fan of BOVs; as I like to add performance/reliability and I'm not much into things that are there for sound/style.

This should give you a good idea of what adding a BOV does to a car

If you have a high boost application and you tear your DV membranes frequently there is the GFB DV+ that could be considered a performance upgrade.

Generally DV are not a weak point on most cars, and are pretty cheap/easy on the M at least to replace when/if they fail. I think I replaced both of mine for $120, and under 20 minutes. Mine were fine vintage 2011/61K miles, I replaced them tracking down a 30FF error. They were not the cause.

Sorry but this is just not true ..... this is a performance upgrade ....

A diverter/bov are literally the same thing saying your not a fan doesn’t make sense the only difference is recirculating and venting to atmosphere

I logged a ton when I was testing my setup and never had a problem with a fully vented to atmosphere setup - remember this engine does not have a MAF

GV+ bits imo are a rip off

[Ebtahi98]

They are on eBay and they come in a pair they look to be of high quality I mean this is not a variable vane turbo charger for Christ sake so I mean it's not that difficult to design lol sorry that's the mechanical engineer in me talking lol But take a look there really good at least they look good to me if anybody is ever heard of problem or think these are shit please let me know because I'm looking to pull the trigger on them. If you click on the picture the price and info will come up swipe to the right and you'll get more info, I think it's $286 for the pair is decent
I'm just curious to know if anyone's ever use these?

Thanks. I am familiar with BOV's, was curious on what difference it does in the X5M platform, which is really the same as I know them be. With a stage 1 tune, seems to me the OEM Diverter valve will do fine with the mild boost increase.

Never having a problem is different than increasing performance. A DV and BOV are not the same thing when it comes to performance.

You are right about the differences between a BOV/DV but incorrect on the performance impact. Adding a BOV to a diverter equipped car will reduce performance in proportion to the amount of pressure it vents to atmosphere. Vent to atmosphere = loss of turbine speed and spool. Diverter recirculates boosted air keeping the turbo spooled which = a minor loss of spool during shifts and throttle let off. BOV vented boosted air to the atmosphere, stalling the turbine and increasing lag as the system has to re-pressurize the intake once full power is demanded. Car manufactures went to DVs for the performance benefits, folks go to BOVs for the sound.

On the X5M I'd say neither product a BOV or DV+ is of any real performance benefit.

I can't say I've heard of a rash of torn DV's on the X5M. This doesn't seem to be a weak point on these cars. The Diverter valve on the X5M seems to be exactly the same design as used on VAG cars. Probably interchangeable.

I can speak on my GTI, that I went big turbo and had 28-31psi of boost on the stock DV without any issues. Folks aren't running their X5M in this range with stock turbos.

As part of my endless modding I did try the DV+ on the car and didn't find it made really any difference over the stock DV. Their advertising was sold as having faster throttle response etc. My highspeed logging (120hz) couldn't find any real difference. It did change the noises slightly.

So my general opinion other than for sound in the case of the BOV, there isn't any real need for any of this stuff on a stock turbo X5M. Spend your money elsewhere.

My DV's on my 2011 X5M with 61K miles original, I replaced a few months ago chasing a 30FF. They were not the cause of my problem and they were not torn/leaking and were working fine. But I replaced them anyway as part of my trouble shooting. It was a combination of tired MAF sensors and bad pneumatic pressure converters for me. After the MAFs were replaced no more reduced power, but occasional weird stumbles with no check engine lights. Pressure converters replaced car ran good as new. They are a PIA to replace.

The S63 engine does not use a MAF - it uses dual MAP sensors - both of which are after the diverter valve and do not ever measure the air it dumps back ... I know the engine will through a code with the stock setup if you mess with the diverter valve or remove the hoses.

You can switch to a vacuum operated valve or this turbosmart one and it will work the same as OEM without the code - I know this because that is what I did on mine for over 5k miles and never had an issue.

This is honestly only for the people that don't mind spending money in the hope that it will last longer because the OEM valves do eventually fail and cannot be serviced - there is no other option for a full bolt on replacement valve on the stock system.

Your correct in that the system uses the same diverter valve as other cars the whole S63 is nothing but a frankenstien of a car mashed together.

Valve seals can't be serviced?

Right, the X5M while it doesn't have MAF sensors to reduce intake airflow restrictions, does not mean the car does not calculate mass air flow via other means. The S63 does away with the mass airflow meter used in the N63, which can account for reducing intake manifold pressure by as much as 28%, in favor of calculating the necessary data by using input from an array of sensors measuring air temperature, engine speed, throttle position, variable valve timing adjustments and intake manifold pressure. So the car knows exactly what is Mass Air Flow is without using a MAF sensor. That why a full on BOV will trigger an engine code.

How often does the stock DV fail on this car? It seems to last years without issue and has not been identified as a weak point. Absolutely a failed DV can be replaced/serviced, I have done so. They are $73 each and are one of the easiest replacement jobs you can do on an X5M. Just remove the air intake, and there they are held on by a handful of hex screws and 1 plug. Done in 20-30 minutes even for those not mechanically inclined. I can buy a lot of DV's at $73 a pop that last years before I'd equal the cost of one $229 BOV. What 3x each?

I've had my car 9 years and the DVs never failed, both the DV+/BOV just seems like expensive solutions looking for a problem. Not to say there aren't use cases for both, enhanced sound for BOV, and potential better durability under high boost situations on the DV+, with upgraded turbos.

From that perspective aren't all cars just a combination of 3rd party supplier parts? With some tuning, esthetics and a little engineering thrown in to differentiate their vehicle from others using the same parts?

Yes they can, the DVs are replaceable, quite easily in fact. I've actually serviced mine as preventative while fixing a 30FF error.

They're easy to access, part swap.

You just replace them ...

Here is a photo of some prototyping I did with my TU turbos upgrade ... notice the DV deleted and where the air is recirculating? - I figured this engine out already I know how it works
