equations for inj. flow rate for small engine

[andy quaas]

I'm looking into efi-ing an onan 2-cylinder (about 18hp) 4-stroke gas
engine.  Not a throttle body injection, but port (its easier to mount
the injectors on the intake than to make a TBI with injectors.  What
is the math that needs to be done to calculate the injector size?  How
about TBI flow rate or diameter?  Thanks a bunch!
