I am trying to understand the differences in the nitrous Solenoids. From reading online the power output capability is determined by the orifice size and i assume the price differences are from the plunger material? I plan on getting a pair nitrous solenoids for a direct port system for each cylinder. As each solenoid would be set up for 4 cyclinders, would the sum of the nitrous jet size for each fogger for the 4 cylinders need to be less than the orifice and is their a percentage of by how much? I dont plan on making a 500hp shot of nitrous but trying to understand how the math works. Been using RobietheRobot nitrous jet size calulator as a reference.
