If you're running secondary injectors that can't be located directly at the port, is there an optimum location on the intake runner (ie along the short radius or something) so that the fuel is atomized in an optimum manner, and is there anything to pointing the injector upstream rather than downstream assuming it's only open under boost?

Thanks

You should never point up stream. A secondary injector should be placed where it is tangent to the air flow. If you mount it behind the primary injector, try to "aim" the secondary unit so it won't wet out the primary. If you have a short turn that is accessable, either head or manifold, you'd get pretty good atomization..go for it.
