Mounting the Bottle
The 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 11708 and 11709) must be installed. The best positioning of
the bottle is shown in diagram “A”.
DIAGRAM A
Mounting the bottle in this manner will allow the internal siphon tube to be covered
with liquid nitrous at all times and properly supports the bottle. Refer to the chart
below to determine the suggested bracket spacing.
Assemble the brackets on the bottle with the short bracket on the bottom
(motorcycle brackets are the same height) and the top bracket the s pecified distance
apart as shown on the chart below. This assembly will serve as a template to locat e
the four mounting holes. The bottle brackets should be secured by grade 5 bolts
and washers. Before drilling the holes be sure to check for clearance beneath the
mounting surface, i.e.: fuel tank, fuel lines, and brake lines. Each dimension given
below is from the bottom of the bottle to the center of t he bracket, a 10% variance
in spacing, if necessary, is acceptable.

DIAGRAM B
Bottles mounted with the brackets in or near th e middle will oscillate causing metal
fatigue resulting in bracket failure. Billet brackets are suggested for
installations on ATV and motorcycles, or any vehicles used in rough terrain
or where band style clamps allow vibration or oscillation to occur. If band-
style brackets ar e used, a minimum of two brackets must be installed when using a
7oz or larger bottle. Nitrous Express does not recommend the mounting of
bottles to the swing arm or any portion of the suspension of an ATV or
motorcycles. SCTA and BNI require an approved blow d own tube (PN 11711P) on
all motorcycle installations.
