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 opeation of the nitrous system. Please read the entire bottle mounting instructions 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 bottle of the bottle, opposite the bottle label (as pictured above).
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° towards 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 positioned
correctly.
2.3 Nitrous Bottle Installation
After you have determined the location and orientation of the nitrous bottle, use the following
procedure to install the nitrous bottle:
1. Disconnect the vehicle’s battery.
2. Determine the location of the bottle within the confines of the rear of the vehicle.
3. Once a mounting location has been determined, raise the vehicle (following all safety
practices involved in working on a vehicle from under the vehicle) and verify that there are
no fuel lines, fuel tank(s), brake lines, emissions equipment, or structural members in the
way of potential mounting bolt locations.
4. Install the rubber insulators within the bottle brackets.
5. Install the bottle in the bottle brackets.
6. Using the mounting bracket bolt holes as templates, mark an area for each of the brackets
with chalk, scribe, or marking pen to locate the bottle placements for drilling.
7. Drill two 3/8” mounting holes for each bracket making absolutely sure that you are not
drilling into anything dangerous or critical to the safety of the vehicle.
8. If a bottle heater blanket is going to be used, be sure that brackets are installed 8½” apart
from each other.
9. Install the bottle mounting brackets using “Grade 8” bolts, nuts and flat washers (not
included with the kit). Use fender washers underneath the vechile for sheet metal mounting.
10. Tighten the mounting bolts using a thread locking compound.
Optional Blowdown Tube (PN 72960) Installation
11. If you are using a safety blowdown tube, mock this up on the bottle to decide where the tube
will go through the floor.
12. Mark the floor where the tube will go and using a ½” drill bit, drill through the floor on the mark.
13. Install the Safety Tube on the bottle and cut off any excess tube so that only 1”to 2” are protruding through the vehicle.
The most efficient mounting
method is the lay-down
position with the valve handle
towards 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.
Shown here is a bottle with
a bottle bracket properly
installed with the rubber
insulator. The distance
between the bottle brackets
is somewhat adjustable.
Remember, mount the short
bottle bracket at least 1”
from the bottom of the
bottle, and never cover any
of the bottle labels with the
bottle bracket.
Do not attempt to install the
bottle in the bracket
without the rubber
insulator.
