W205 C63 RacePort Adaptor BOV
The factory electronic BOV (Blow Of Valve) in stock form vents back to the factory air-box when it is told to by the ECU. For stock cars driven by mum taking the kids to school this is more than adequate.
Got "Stage 2" or more though? The tiny factory system is likely leaking! plastic piston against a plastic seat, it isn't really up to the task now.
Have you also noticed the factory BOV is also used to control traction? especially between gears and even with traction control turned right off? YEP! So did we!
INTRODUCING our C63-RPA (RacePort Adaptor)
The BOV job is to vent boost when you close your throttle. When you close the throttle your turbo's are still boosting, but the gate is closed! The boost has to go somewhere. It either goes back through the turbos (flutter/dose sound) damaging turbo bearings, and slowing spin. Or it goes out your BOV. Given we have seen factory turbos with under 70 000 kilometres that have worn bearings and massive end float. We highly suggest you retain a form of BOV.
