How to get bov for N55 big single?

zohaibrose · 04-08-2024, 08:33 PM

Ik N54 guys can convert to a bov pretty easily but was wondering how n55 guys can esp since these engines have Valvetronic, normally I would revert to the diverter valve but since I went big single with a external wastegate I was wondering how to run a Bov since the throttle body’s always open, anyone found a fix ? Linked a pic of my current setup but isn’t working correctly

you either need to dump the extra air from your bov somewhere between the turbo and maf sensor, or you need a mafless tune if you just want to dump it into the atmosphere.
