BOV or Recirc Valve for N18 Motor Which do I go with??
Wondering which to go with for an N18 R56. I have done a lot of reading and I still seem a bit lost on the understandings. I see Forge makes both for the MINI and I understand the difference but don't understand how to determine which is best for my application. Thanks!

"Not all turbocharged engines are made for blow-off valves, they might need a bypass (aka diverter or recirculating) valve instead. They both accomplish the same task but there’s a big difference in how they do it. The type of engine management your car runs will come into play when choosing a valve. If you have a MAF-type system, it meters the airflow after it enters the intake system. In this case, when a blow-off discharges to the atmosphere, the ECU isn’t able to properly fuel the engine resulting in rich AFRs, hesitation, bad idle and even stalling. In these systems the excess pressure must be plumbed back into the turbo system before the compressor inlet, which is what a bypass valve does."
