Not to nitpick, but remember that each cylinder only intakes once every OTHER revolution. You need to divide that number by two.
Also, since the manifold has a vacuum, you can argue that it never fully consumes 8400 liters of air per minute if that air is at 1 atm of pressure. It's probably closer to 5000. Not to say that still isn't a lot - because it is!
