Pushrod Style 5.0L Plate Instructions

Congratulations on the purchase of your Nitrous Express EFI 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 EFI Plate System is designed to operate

with stock fuel pumps and no timing retard, 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 be compatible if higher octane fuel

or NX Power Booster (PN # 16003) fuel additive is used.

To insure proper system assembly and operation, carefully read the following installation procedures thoroughly before beginning.

Before starting, carefully disconnect the vehicle negative battery cable. If there is any question about this operation, consult the vehicle owner’s

manual!

DO NOT use any sealer on flare connections, hose, or bottle connections. Use the furnished NX red liquid thread sealer; use no other sealing

compounds or Teflon tape.

Excessive tightening of parts is not necessary, snug is tight enough. If it is necessary to remove a fitting installed with the red NX sealer, heat

may need to be applied to release the sealing agent.

NOTE: Due to shipping restrictions all NX nitrous bottles arrive empty. Before beginning the installation the N2O bottle should be filled by a

NX accredited filling station. For filling station locations log on to www.nitrousexpress.com

MOUNTING THE

BOTTLE

The nitrous bottle should be mounted in the

trunk

area or outside of the passenger compartment. If

this

is not possible or practical a

NHRA approved blow

down tube and vent fitting (PN’s 11708, 11709)

must

be installed. The positioning of the bottle should

shown in illustration “A”. This will allow the

siphon

tube to be covered at all

times.

The mounting brackets should be assembled

the bottle with the short bracket approx. 2” from

the

bottom, on 10 lb. bottles the long

bracket should

place approx. 7” above the lower one, on 15lb

bottles

the upper bracket should be approx. 12” above the

lower

bracket. Use this mock up as a template to

locate the four mounting bolt holes.

Note:

Before

drilling holes be sure to check for clearance

beneath

the mounting surface i.e.: fuel tank, fuel lines,

brake lines.

MOUNTING THE NITROUS PLATE Before any modifications are made under the hood, we suggest that you make a diagram of all hoses wiring and linkages. 1. Pre-assemble the nitrous plate before you begin.

FUEL SUPPLY CONNECTION WARNING: THE FUEL RAIL AND/OR FUEL LINES ARE UNDER HIGH PRESSURE. USE EXTREME CAUTION WHEN DISCONNECTING ANY FUEL LINE. QUICKLY COLLECT AND PROPERLY DISPOSE OF ANY EXCESS FUEL SPILLAGE FACTORY “FUEL TEST-PORT” 1. Located on the fuel log (injector rail) is a “test port” fitting used by mechanics for checking fuel pressures. This is usually covered by a black plastic cap and is where the fuel solenoid feed line will be connected.

Note: The nitrous and fuel solenoids are rated only for intermittent duty. Do not engage either solenoid for more than 20 continuous seconds. Solenoids that have “burned or scorched” electro-magnets will not be replaced under warranty. WIRING DIAGRAM TESTING AND USING THE SYSTEM All NX systems are designed for off road usage. Use extreme caution and observe all safety precautions (see your vehicles owner’s manual). Select a suitable test area; your local racetrack is best.

POWER TUNING TIPS Nitrous oxide works well with all applications; 4 cycle, 2 cycle, diesel, and rotary engines. Each one has individual tuning characteristics, and these tips apply generally to each one. Nitrous oxide is referred to as “Liquid Supercharging” because it, in effect, does the same thing as a mechanical supercharger, forcing more fuel and oxygen into each cylinder, thus producing more power. The biggest enemy of all supercharged, turbo charged and nitrous injected engines is “DETONATION”.

F. Racing fuel should be stored in an airtight, dark container. Exposure to atmosphere allows very important elements to evaporate, lowering the octane of the fuel. Sunlight oxidizes the lead contained in racing fuel, since this is the most important ingredient used to raise octane it must be protected. G. Never leave the fuel in your car between race days. This allows evaporation of the very important “High end” hydrocarbons and lowers the octane of the fuel. H.
