M3/M4 owners with BOV

[Tempa]

Hey All,

As per the title, I was wondering any m3/m4 owners here have a BOV on their car? If yes, what brand is it? Did it come with piping?

Thanks.

It's pretty rare to find these on the forums. Most choose not to.

Why not consider an open cold air intake? Loud intake noise sounds similar and easy to install and reverse with only a minor degradation in power.

internal wastegate

there is no fast n furious bov sounds to be had on the s55

Thanks for the input guys. Was really just asking in behalf of a friend who had a 335 and kept the BOV from that car and now wants to install it on the M4.

Any turbo car ( Petrol ) CAN have a BOV, most do.. just plumb back.
Internal wg or External does not matter.
Pretty sure the S55 runs a divertor valve or something.

The dv's are built into the turbo compressor cover and controlled by ecu - hence the characteristic s55 fart when you dump boost

Sure anything is possible, but in this case, it's no feasibly possible when you factor in not only the hardware work around but also the tuning

I'm under the impression there is no DV in the S55 and the compressor surge is handled by the ALS ie. throttle plate actuation and timing.
