combustion chambers, making this mostly a non-issue for these applications. Single nozzle A single nozzle nitrous system introduces the nitrous or fuel/nitrous mixture via a single injection point. The nozzle is typically placed in the intake pipe/tract after the air filter, prior to the intake manifold and/or throttle body in fuel injected applications, and after the throttle body in carbureted applications. In wet systems the high pressures of the nitrous injected causes the aerosolization of the fuel injected in tandem via the nozzle, allowing for more thorough and even distribution of the nitrous/fuel mixture. Direct port A direct port nitrous system introduces the nitrous or fuel/nitrous mixture as close to the intake ports of the engine as is feasible via individual nozzles directly in each intake runner. Direct port nitrous systems will use the same or similar nozzles as those in single nozzle systems, just in numbers equal to or in multiples of the number of intake ports of the engine. Being that direct port systems do not have to rely on intake tract/manifold design to evenly distribute the nitrous or fuel/nitrous mixture, they are inherently more precise than other delivery methods. The greater number of nozzles also allows a greater total amount of nitrous to be delivered than other systems. Multiple "stages" of nitrous can be accomplished by using multiple sets of nozzles at each intake port to further increase the power potential. Direct port nitrous systems are the most common delivery method in racing applications. Plate A plate nitrous system uses a spacer placed somewhere between the throttle body and intake ports with holes drilled along its interior surfaces, or in a tube that is suspended from the plate, for the nitrous or fuel/nitrous mixture to be distributed through. Plate systems provide a drill-less solution compared to other delivery methods as the plates are generally application specific and fit between existing components such as the throttle body-to-intake-manifold or upper-intake-manifold-to-lower-intake-manifold junctions. Requiring little more than longer fasteners, plate systems are the most easily reversed systems as they need little to no permanent changes to the intake tract. Dependent on application, plate systems can provide precise nitrous or fuel/nitrous mixture distribution similar to that of direct port systems. Bar A bar nitrous system utilizes a hollow tube, with a number of holes drilled along its length, placed inside the intake plenum to deliver nitrous. Bar nitrous delivery methods are almost
