#82040B Blackout Series

Perimeter Plate Nitrous System

Thank you for choosing ZEX™ products; we are proud to be your manufacturer of choice. Please read
this instruction sheet carefully before beginning installation, and also take a moment to review the
included limited warranty information.

Why our nitrous system is better:

• Fits all popular square flange 4-barrel intake manifolds. Easy to install.

• Adjustable from 100-300 horsepower. Safe enough for stock engines, powerful enough for

racing use.

• Injects at 12 unique points surrounding the intake manifold plenum. Eliminates 30 year-old

technology spray bars and optimizes distribution of fuel and nitrous into the engine.

• Cryogenic design flows super-chilled nitrous through the entire plate, before being sprayed into

the engine. This creates a cooling “deep freeze” effect on the carburetor and intake manifold for
additional power.

• The perimeter injection plate is machined from solid billet aluminum. This ensures precision

flow, unlike cast plates and old-technology spray bars the competition uses.

Quick Start Reference Guide:

• How the ZEX™ Perimeter Plate Nitrous System works: The ZEX™ Part #82040B nitrous

system begins with a connection to a supply cylinder containing pressurized liquid nitrous
oxide and a connection to the engine’s fuel system. These connections go to the system's
nitrous and fuel solenoids, respectively. These solenoids are normally closed but are opened
when the nitrous system is armed, and the throttle switch is activated by the carburetor going to
wide-open throttle. Once these solenoids open, the nitrous and fuel are delivered to the
injection plate via braided stainless steel delivery lines. The amount of nitrous and fuel that is
injected through the plate is adjustable by means of metering jets installed in the plate itself.
These metering jets allow for easy changes in horsepower settings.

• What is nitrous oxide? Nitrous oxide is a gas composed of two nitrogen atoms bonded to one

oxygen atom. The scientific abbreviation for one nitrous oxide molecule is N2O, where N is
nitrogen and O is oxygen. This is where the familiar phrase “N-2-0” comes from when people
talk about nitrous oxide.

• How nitrous oxide makes power: Nitrous oxide kits make large amounts of horsepower by

allowing an engine to burn more fuel. Burning more fuel creates higher cylinder pressures that
will push down on the piston with greater force. When the nitrous is injected into an engine and
the initial combustion takes place, it creates enough heat to separate the nitrous oxide into its

two components, nitrogen and oxygen. Once separated, the additional oxygen is then free to
react with additional fuel. To run nitrous successfully and safely, you have to introduce precise
amounts of additional fuel with precise amounts of nitrous oxide. All of the extra oxygen
provided by the nitrous oxide must have fuel to react, or you may damage your engine severely.

• All the power comes from the fuel, not the nitrous. Nitrous oxide is a simple tool that allows

you to adjust how much and how quickly the engine burns the fuel. If the fuel isn’t there, the
power won’t be either.

• Avoid detonation at all times. Nitrous oxide enhanced detonation is much more damaging

than detonation that occurs when naturally aspirated. This is due to the increased amount of
fuel available for releasing energy and the fact that more oxygen is present.

• If, when your system is activated, something doesn’t feel or sound right, BACKOFF! If

you hear any detonation or feel anything unusual, get off the throttle. It’s a lot easier to check
everything over than it is to just try to drive through it and damage expensive parts.

• Work safely. Always wear eye protection and gloves when working with lines or hoses that

contain pressurized nitrous oxide or fuel. Never transport nitrous cylinders loose in a trunk or
the bed of a pick-up truck and especially NOT within a vehicle’s interior whether the cylinder
is empty of full. Always disconnect the ground side of the battery when working any electrical
components.

• Nitrous oxide will not fix problems you already have. Before you install your nitrous system,

be sure your engine is in good mechanical condition. Intermittent wiring problems, etc., can
lead to erratic system performance and possible engine damage.

• Never defeat the operation of the safety relief disc in the nitrous cylinder’s valve stem. It’s

required by law and is there for your safety. Never drill, machine, weld, deform, scratch, drop,
or modify a nitrous oxide cylinder in ANY way whatsoever!

• Never overfill nitrous cylinders. That little bit extra will put you and others at risk of injury.

More often than not, when the cylinder warms up, the pressure goes above the limit of the
safety relief disc, and you lose all the nitrous you just paid for.

• Do not use Teflon sealing tape on any fittings in a ZEX™ nitrous system. It is easy for

Teflon tape to get pulled into the system, causing blockages that can ultimately lead to incorrect
nitrous system performance and potentially, engine damage. Only use liquid thread sealer for
all NPT type fittings. Do not use any thread sealing compound on AN style fittings.

• Do not attempt to start your engine if nitrous has been accidentally injected into the

engine while it was not running. Disable the ignition and, with the throttle wide open, turn

over the engine for several seconds to clear the nitrous from the engine. Failure to do this
before restarting the engine can lead to a dangerous intake system backfire.
