I have my gen 1 rcc stage 1 running 8lbs of boost. It was tuned without water injection. Now that I have the W/I kit on the bike I would like to use it as a safety measure, and for hp gains down the road. At 14.2 volts the nozzle I have sprays approx. 124cc/min. Is this a good size for around 257hp running 50/50 water/meth? I have plans to run 290 hp. Does anyone know a good nozzle size for that hp range?
