I realized afterward my math wasn't taking the 4 stroke into account. but, is the above math by 304065 right?

each cylinder still draws it's displacement of air each second revolution of the engine. so my figure was twice as large as it should be.

so a 3.0 liter is drawing 9000 liters/minute at 6000rpm. which makes it 150 liters per second.

or, each cylinder draws .5 liters each second revolution. at 6000 rpm each cylinder draws 3000 times .5 liters. that makes 1500 liters per minute per cylinder. times 6 cylinders divided by 60 seconds in a minute makes it 150 liters per second.

still seems like a lot of air to get thru the engine grill. I having trouble imagining 7-1/2 five-gallon pails of anything going thru the grill every second. yet, it's happening.

has anyone done a dyno test with the lid open and closed and compared?
