1. NITROUS EXPRESS NEXT GENERATION NITROUS SYSTEMS ELECTRONIC FUEL INJECTED 5 0 COYOTE PLATE SYSTEM INSTALLATION INSTRUCTIONS Congratulations on the purchase of your Nitrous Express Coyote Plate system Nitrous Express utilizes only the highest quality components designed for the use of liquid nitrous oxide To properly utilize these specially designed components and obtain the trouble free operation that this system is capable of producing it is extremely important that you read all instructions carefully Pay special attention to the important notes at the end of the installation steps and the tuning tips listed at the back of this instruction sheet The NX Coyote Plate System is designed to operate with stock fuel pumps and no timing retards up to the 100 horsepower setting On all settings above 100 horsepower the following precautions should be observed A An extra capacity aftermarket fuel pump must be used 250LPH Minimum B High octane race type fuel and or timing retard must be used to prevent detonation C Increased strength internal engine components and high performance head gaskets may be required D Depending on compression and fuel quality timing retard may be necessary to prevent detonation If you have an aftermarket ECU tuner that advances the stock timing detonation could be a problem These aftermarket tuners can compatible if higher octane fuel or NX Power Booster PN 16003 fuel additive is used To insure proper s2. If not stop and recheck all installation procedures Call the factory tech line if the problem cannot be located NOTE All vehicles equipped with factory rev limiters should take extreme care not to over rev the engine If the rev limiter is engaged with the N2O system on serious engine damage could result An aftermarket RPM window switch NX PN 18959 should be used to disengage the N2O system 200 RPM s before the rev limiter activates Your NX system is now ready for regular usage SAFETY TIPS Do not attempt to start engine if nitrous has been accidentally injected while the engine was not running Disconnect coil wire and turn motor with throttle wide open for several revolutions before attempting to restart If it is not possible to disable the ignition then the spark plugs must be removed and the engine cleared of all nitrous before attempting to start engine 1 Never permit oil grease or any other readily combustible substances to come into contact with nitrous cylinders valves solenoids hoses and fittings Oil and certain gases such as oxygen and nitrous oxide may combine to produce a flammable condition 2 Never interchange solenoids or other appliances used for one compressed gas with those used for another 3 Identify the gas content by the label on the bottle before using If the bottle is not identified to show the gas contained return the bottle to the supplier 4 Do not deface or remove any markings which are u
