        "note": "Engine mass airflow ≈ displacement × (rpm/2) × volumetric efficiency × the charge-air density (here at the manifold pressure, idealised intercooled to inlet). It is the y-axis of the compressor map: plot it against the pressure ratio to land in the compressor's efficient island and avoid surge or choke. A 2.0 L at 6,000 rpm naturally aspirated moves ~15 lb/min; boost scales it up with the density.",
