7. OUTLET PLENUM DISCHARGE TUBE
A. Temporarily place the 2 3/4" diameter blue
sleeve on the supercharger outlet as far as
it will go.
B. Slide the two 2" diameter blue sleeves onto
the throttle body inlets, temporarily, as far as
they will go. It is easier to unscrew and open
the clamps and place them after sleeves are
in place.
C. Fit the smaller ends of the plenum into the 2"
sleeves and check the alignment with the
supercharger outlet. It may be necessary to
loosen the bolts on the mounting plate to
achieve proper alignment. In some cases
the socket head screws on the perimeter of
the supercharger must be loosened and the
volute housing rotated slightly. Do not over-
tighten these screws, torque to 6-8 ft/lbs.
D. Once proper alignment has been achieved,
slide the sleeves onto the plenum and se-
cure with the hose clamps.
NOTE: If installing the kit on a 5.8
Lightning, disregard points B, C
and D. Install the discharge tube
to the throttle body using the 3"
x 2" sleeve and the clamps
provided. (See Figures 7-a, 7-b.)
