This is the formula we use at work to work out air flow needs

Air flow (CFM) = Displacement (cubic inch) X RPM X VE
1728 CF


CYCLE FACTOR (CF)
CF: 4 cycle diesel/petrol engine = 2
CF: 2 " " " " = 1


VOLUMETRIC EFFICIENCY (VE)
Naturally aspirated diesel/petrol engine = 0.85
Supercharged engine = 1.2
Turbo engine (we use this on for diesels) = 1.4


Eg Airflow = 109 x 6000 X 0.85
1728 2


= 555900
3456


= 160.85 cfm (this suits a 1800cc engine)


Litres to CI

1 LT = 60.5 CI eg 1.8 lt X 60.5 = 108.9 CI
