Depending on the final specificationa, the capability required.
Progressive pump system analysised:
Apart from the limited dynamic range (unless you have a pump that can delivery between 50psi to 1000 psi), you will still fall short of the power range of an engine.
Progressive pump speed system is also quite slow to react to change fo transient load, for example: change up or down a gear could mean a change of delivery quantity of 1000rpm. A rotating mass (pump motor) will not be fast enough to react to this change. So you have one more things to consider if you want to go for a anaogue pump speed controller.
Pulsed delivery will not affect the engine dynamics that much, considering the engine only have one intake stroke per revolution (I think?). Since droplet size is a mixed bunch, smaller droplet to travel faster towards the throttle even it starts at the same point. So in real time, you have a continuous train of water droplets spread over the entire inlet tract.
I think you should really consided a system similar to the fuel injection system adopted by almost all car makers.
