3.0 liter airflow rates
Does anyone have a rough notion of how much air is used to aspirate the 3.0 liter engine? At idle is it on the order of 3.0 grams per second? At max HP is it upwards of 500g/sec?
Thanks, Jim S.

According to my calculation (just a simulation) 3.0L spinning at 6000 RPM's at VE of 92% would gulp 164g/sec worth of air.

Lets see
3.0 liters = 3,000 cubic centimeters 6,000 RPM means it sucks are in 3000 times/minute. Assuming VE of 0.92 (I don't know), air weights 0.0129 grams per cubic centimeter at 0 degrees C. So 3,000 cm3 x 3000 x 0.92*0.0129 g/cm3= 10,868 grams/minute at 0 degrees C. or 178 grams/second For say 70 degrees F (21.1 C) you have to start with absolute zero which is -271.15 C, so multiply 273.15/273.15=21.1 (92.8%)= 165 g/sec
