    Just a very quick one for you folks as my google-fu is letting me down badly: Does anyone know the volumetric efficiency of the 4.4 lump in the E63? Or the cfm of this engine at 7000rpm?

  11. BMW 1 Series - Tech Talk For All Gen Of 1 Series
    I was thinking of buying the 143bhp 118d because I love the sound of the fuel efficiency considering the power, but I've since learned they're pretty much guaranteed to have the timing chain snap and it's not a risk I can afford. This leaves me with three options - the less powerful and less...
