100 octane<93 octane

[427]

Need some questions answered about new Auqamist water inj system I have purchased. I am in a time crunch and need to test it soon. Did not come with any guidelines to nozzle size and placement.
What nozzle size should be used?
How many nozzles should be used?
What placement is best?
I am using 6.0L v-8 with supercharger. It runs 860 ft lbs and 1069 hp on 100 octane unleaded with 25+ pounds boost. Need to run on 93 octane now. Is this possible?
