Editing Nitrous oxide engine (section)

===Dry===
In a ''dry'' nitrous system the nitrous delivery method provides nitrous only. The extra fuel required is introduced through the [[Fuel injection|fuel injectors]], keeping the manifold dry of fuel. This property is what gives the dry system its name. Fuel flow can be increased either by increasing the pressure or by increasing the time the fuel injectors remain open. 

Dry nitrous systems typically rely on a single nozzle delivery method, but all of the four main delivery methods can be used in dry applications. Dry systems are not typically used in carbureted applications due to the nature of a carburetor's function and inability to provide large amounts of on-demand fuel. Dry nitrous systems on fuel injected engines will use increased fuel pressure or injector pulsewidth upon system activation as a means of providing the correct ratio of fuel for the nitrous.
