There was a detailed article about a bevel box oil cooling system by an American called Graeme Addie in the MTWC Bulletin dated October 2015. It was very complex with a pump, filter, heat exchanger, cooling fan and multiple sensors and appeared to take over much of the limited available space in a M3W. No doubt it worked a treat but it wasn't simple or compact. Hopefully this system will improve on that.
My cars Bevel Box screams at anything much over 60mph when it is hot but is quiet for the first 15 or 20 minutes from cold. I can only assume that BB cooling will be a good thing for reduced noise and wear.
