Hey All,

I have been searching all over for information regarding Forge BOV adaptor and the R55 with poor results. Just bought a 2012 clubman S and was interested in this adaptor because theoretically it will save on the wear and tear on the turbo. I have some questions if you all don’t mind terribly. Or if this topic was covered in detail in another thread please point me in that direction. Thanks.

1. Will this adaptor void my factory warranty?
2. Will this adaptor damage my motor in any way?
3. Will this adaptor cause my ECU to start flashing error codes?
4. Is this unit as easy as they say to install for the mechanically inclined?
5. Can I fool the dealer by removing this adaptor before taking it in for service?

I'm curious on where this info was found, because that's not entirely true...

If the turbocharger fails, the dealer would have to prove the installation of the adapter was a direct result in the turbocharger failing.
However, some dealers play bigger hard-ball than others...

Not to be snide, but do you know what the purpose of this parts does?
This piece dumps unused boost to atmospheric versus recirculated back into the intake system.

It's possible it can.
The boost system of the MINI is a "closed-loop" system when the original unused pressure is diverted back into the intake system.
With the adapter, the meter air from the MAF sensor is now vented to atmosphere which is removed from the system.
The ECU thinks that air is still present, and calculates fuel trim accordingly, but it now is inaccurate; typically if a fault appears, it's show as "fuel trim too rich".

A handful of bolts to remove and reinstall, and you're done.

I bet you could...

^^^All of this is true.

 

Thanks Erick for the answers to my questions. I never had a turbo car before so I am a bit new to the whole boost game. I came out of a 5.7L V8 Hemi Ram 1500 and I am so happy for the change. According to what I have been reading on the internet this Forge adaptor is suppose the help the turbo system run a bit cooler thus making the turbo last longer,.....don't know how true that is or maybe I am mistaken what I am reading. Thanks again..

 

It's absolutely no different than the DV that comes on the car. It just makes more noise. One COULD make the argument that you may be adding heated air back into the intake tract (which is technically correct) but it's not enough to raise the temp of the incoming air charge.

 

The impact as quality_sound referred to is so insignificant that you won't notice anything.
If you're looking to lower charge temperatures, grab a quality intercooler or water/methanol kit.

Cool...Thanks guys for explaining so clearly...appreciate it very much.

 

Does anybody know for sure if this will cause a CEL or not?? Seeing as the system is both MAP and MAF based?? It may throw a MAF error correct??

 

Yes, it can produce a CEL.

Typically it's more of a "too rich fuel burn condition" code you'll see when a designed closed loop system is incorrectly dumping metered air into the atmosphere.

Im aware it can cause a CEL. I know some cars dont being both MAF and MAP based. Im asking if people have actually used it and encountered a CEL. My supra for example. Im running a full aftermarket fueling system thats MAP and MAF based and doesnt care at all about the atmosphere vent BOV. But my eclipse cared and threw a CEL for a rich code and MAF error.

 

Yes, some have with the BOV adapter installed.

The MINI's ECU parameters are more restrictive and only provide narrow windows than the earlier Toyota platforms.
