technical types of nos systems technical information efi wet dry systems an overview of wet dry and direct port systems these are three basic types of nitrous systems dry wet and direct port the most misunderstood is the dry type of system a dry nitrous system simply means that the fuel required to make additional power with nitrous will be introduced through the fuel injectors remember fuel makes power nitrous simply lets you burn more of it this keeps the upper intake dry of fuel we accomplish this by two methods first is to increase the pressure to the injectors by applying nitrous pressure from the solenoid assembly when the system is activated this causes an increase in fuel flow just like turning up the pressure on your garden hose from 1/2 to full the second way we can add the required fuel is to increase the time the fuel injector stays on this is accomplished by changing what the computer sees basically tricking the computer into adding the required fuel in either case o

technical tuning question answer technical information efi wet dry systems here are answers to the most commonly asked questions about nos nitrous oxide systems along with tech information compiled by the nos research and development team hidden systems q a will nitrous affect engine reliability the key is choosing the correct h.p for a given application a kit that uses the correct factory calibration does not usually cause increased wear as the energy released in the cylinder increases so do the loads on the various components that must handle them if the load increases exceed the ability of the components to handle them added wear takes place nos kits are designed for use on demand and only at wide open throttle nitrous can be extremely advantageous in that it is only used when you want it not all the time all nos kits are designed for maximum power with reliability for a given application nos is actively involved in many aspects of racing working closely with many top name racers

technical tuning question answer technical information efi wet dry systems q a are there benefits to using nitrous with turbo or super-charger applications absolutely in turbo applications turbo lag is completely eliminated with the addition of a nitrous system in addition both turbo and superchargers compress the incoming air thus heating it with the injection of nitrous a tremendous intercooling effect reduces intake charge temperatures by 75 degrees or more boost is usually increased as well adding to even more power exceed 15 to 1 generally the higher the compression ratio the more ignition retard as well as higher octane fuel is required for more specific information talk to one of our technicians q a how important is it to use nitrous and fuel filters in a kit some of the most important components of any nitrous system are nitrous and fuel filters to keep contaminants from attacking the solenoid or plugging up a jet nos nitrous filters feature a special stainless steel mesh el

technical bottle temperature nitrous pressure info technical information efi wet dry systems the relationship between bottle temperatures and nitrous pressure tech note the lower the ambient temperature the lower the resultant bottle pressure leading to a potential fuel rich condition although usually not harmful to the engine loss of optimal power can occur on the other hand very high ambient temperatures can lead to leaner burning conditions and loss of optimal performance as well as possible damage to engine components nos gauges are an excellent way to monitor problems before they can occur note nos recommends a bottle pressure of 950psi for optimum performance bottle temp °f -30 -20 -10 0 10 20 32 bottle pressure psi 167 203 240 283 335 387 460 bottle temp °f 40 50 60 70 80 85 97 bottle pressure psi 520 590 675 760 865 950 1069 direct port systems supercharger turbo systems plate systems hidden systems typical nitrous plumbing diagrams for e.f.i applications powersports systems
