Four injectors in RS500 plenum only?
Ayone only run injectors in rs500 plenum position and not in the standard position?
Good or bad results? What injector? What position do the MIS or other top quality manifolds run? (length to valve, runner diameter and injector spray angle?)

It will be awful in the low-mid RPM range, as you won't have the airflow to pick up the fuel, so will suffer from fuel drop-out/ pooling and possible intake backfire which can be catastrophic.......
The bell mouth injectors are really only for the upper range, a lot of ducatis run twin injectors with the bellmouth one coming in at higher RPM.
IMHO stick to the standard position, they are there for a reason.

as above the front 4 are for the low end as the revs and boost comes up the back four come in as it gives optimum power with a injector further from the valve
on the metro 6r4's this is done, but at very high revs the bottom ones are bought back in as with the tops alone its getting "stand off"
