This is exactly the technique that we have resorted to for high flow
rotary applications.  The injectors found on factory Mazda 13B efi
motors are huge - they flow 2-3 times the volume of 'normal' injectors.
Even so, this is not enough for race motors and turbo applications.
We use two injectors per rotor with the second bank staged so that
they are completly closed during idle and only start to open at higher
loads.
