2.2 Bottle Orientation
Accurate calibration of your nitrous system depends on the bottle remaining at a stable temperature. Choosing the
proper location and orientation for your bottle can greatly affect the overall operation of the nitrous system. Please
read the entire bottle mounting instruction section before making your final bottle location decisions.
Bottle placement is critical to the performance of your nitrous system. It is important to understand how the bottle
valve and siphon tube are assembled to properly orient the bottle in your vehicle and ensure that it picks up liquid
nitrous while undergoing acceleration. All nitrous bottles are assembled so that the bottom of the siphon tube is at
the bottom of the bottle, opposite the bottle label.
An Edelbrock nitrous bottle cannot be mounted upside-down. Edelbrock does not offer a non-siphon tube bottle for
automotive use. If the bottle must be mounted parallel to the axles of the vehicle (sideways), the label must be
angled at approximately 45 degrees toward the front of the vehicle. This orientation will position the siphon tube
toward the rear and pointing to the lower rear-facing quadrant of the bottle. All of this positioning information is
critical to system operation. It is most important to draw as much liquid nitrous as possible. The siphon tube cannot
do this unless the bottle is positioned correctly.
The most efficient mounting is the lay-down position with the valve handle toward the
front of the vehicle. This position allows the greatest amount of liquid to be used
before the siphon tube begins to pick up gaseous nitrous oxide.
