8 . SUPERCHARGER DISCHARGE
A. Install the supplied discharge plenum using studs,
spacers, nuts and washers (see Fig. 8-b).
B. Thread the three supplied studs into the factory throttle
body mounting holes (into the intake manifold). The
shortest of the three studs belongs at the rear of the
throttle body. Insert the four spacers into their proper
location (see
Fig. 8-c).
C. Slide the supplied O-ring around the top flange of the
throttle body. Use a light amount of oil on the O-ring to
allow easy installation of the discharge plenum. Carefully
align the discharge plenum to the installed throttle body
studs. Lower the plenum down onto the throttle body
being careful not to upset the O-ring fit. When contact
with the O-ring is felt, push down firmly on the plenum
until you feel it seat on the top of the throttle body (see
Fig. 8-d).
D. Secure the plenum to the throttle body by attaching the
supplied washers and nuts to the previously installed
studs.
E. Remove the 1/2” brake booster vacuum line from the
intake manifold and cut approximately 2” off from the
end. Splice the supplied adapter TEE into the brake
booster line. Run the supplied piece of 1/4” vacuum
hose from this TEE to the 1/4”-5/32” reducer (see
Fig.
8-a).
F. Attach the supplied compressor bypass valve and 1” x
2.25” hose to the plenum using #16 clamps. Orient the
bypass valve as shown (see
Fig. 8-e).
G. Attach the discharge tube from the supercharger to the
plenum using the supplied silicone sleeves and clamps
(see
Fig. 8-e). Connect the 5/32” hose to the nipple
located on the bottom of the supercharger bypass valve
to the reducer previously installed into the brake booster
line.
