Install nitrous solenoids

He wanted to go faster without building a new engine so he for a nitrous oxide system. Just about any V8 engine can handle a —hp shot of nitrous, provided the engine is in good condition. Power levels of hp or more require dedicated components, however. Modern plate systems have come a long way, with increases of up to hp easily achievable. They can be added to virtually all carburetted engines and many EFI-equipped cars and the whole installation can be completed in less than a day!

STEP 1: Nitrous is sprayed and atomised from the minute holes in the intersecting top bars, while fuel exits the parallel bottom bars. This creates a fog of fuel and nitrous. When experimenting with a new system, avoid the temptation to use the biggest jets straight away; always start with the lowest hp jets.

STEP 2: This high-power kit uses two fuel solenoids black and two nitrous solenoids red. Quality electrical connections are very important.

Wiring should be neatly cable-tied to the mounting plate and all connections soldered to prevent open circuits later on down the track. With the fuel lines disconnected use a rag to catch any fuel spills and the carburettor removed, carefully install the longer carby studs.

STEP 4: Install the solenoid mounting plate onto the engine and be sure to use the supplied new gaskets. Then connect the nitrous and fuel lines from the solenoids to the plate. Being a hp system, we started with the hp jets the smallest units supplied. Fuses and relays should always be used on a good installation. Make sure you have good, clean, solid earth connections. STEP 6: Lay out the fuel lines from your regulator to your fuel solenoids. Avoid right-angle bends and be sure the lines are a sufficient size.

This kit needs adequate flow to support up to hp extra, so a dash line runs to the regulator, then dash-6 lines to each solenoid. Use the correct AN spanners to avoid scratching up your fittings when tightening. Alloy fittings should be firm but not overly tight. STEP 7: The inlet to each nitrous solenoid is fitted with a filter see inset to prevent debris from entering the solenoids, which could damage their plungers or cause them to stick open, allowing nitrous to leak into the engine and cause a dangerous induction explosion.

Each fuel and each nitrous solenoid feeds a pair of jets four solenoids feed eight jets, see Step No. However it must be installed and managed properly to prevent engine damage.

Before using your nitrous oxide system you want to make sure you install colder spark plugs, run 93 octane fuel and make sure your engine is in good working condition. Find a safe location to mount the nitrous bottle. Once you find a good location measure the holes on the brackets, mark your holes and drill them for the mounting hardware.

Once the brackets are mounted, install the bottle and make sure port that connects to the nitrous line is pointing down. Install the nitrous line to the bottle. You may need to drill a hole for the line to come up through. Then run the nitrous line to the engine compartment, keeping it away from heat and moving objects. If you have the nitrous line going through a drilled hole, make sure to use a grommet or put protection around the nitrous line so it doesnt get damaged!

Remove the carburetor from your engine then clean the mating surface so the nitrous plate can be installed. With the old carb removed, remove the original mounting studs and install the extended mounting studs.

Decide what "shot" of nitrous you want to run, then install the appropriate jetting into the nitrous plate. Install the nitrous and fuel solenoids to the nitrous plate, making sure you tighten them properly so they don't leak.

Tap into your fuel feed line and install a "T" fitting for the fuel solenoid, this will provide the additional fuel you need for the nitrous. Using your new gaskets, install the nitrous plate into the intake manifold, then the carburetor. Make sure you reattach all of your hoses, clamps and other hardware.
