DISCHARGE INSTALLATION (OPTION)
9.1 DISCHARGE INSTALLATION
(For Use With 8M205-060/068 Carb
Enclosure)
A. Once the carburetor enclosure assembly
installation is complete per the instructions
included in that assembly, locate the
4PCX112-030/038 discharge assembly.
*** NOTE ***
Refer to Fig. 9-a for the following steps.
B. Using the supplied 1/4-20 hardware and gas-
ket, attach the 3.5" aluminum flange to the
carburetor enclosure lid. (See Fig. 9-a.).
C. Secure the 3.5" x 2.0" sleeve to the flange
using a supplied #56 hose clamp.
D. Locate the supplied Race By-Pass Valve.
Secure the valve to the Ø3.5" tube/w welded
flange using the supplied 1/4-20 hardware
and gasket. (See Fig. 9-a.)
E. Install the by-pass valve assembly into the
previously installed 3.5" sleeve and secure
using a #56 hose clamp provided. The by-
pass valve discharge should face the passen-
ger’s side of the vehicle. (See Fig. 9-a.)
F. Connect the 3.5" to 2.75" x 90° molded
elbow between the by-pass tube and super-
charger discharge and secure using the
remaining #56 and #44 hose clamps sup-
plied. (See Fig. 9-a.)
G. Connect the supplied vacuum line to the
vacuum port on the by-pass valve. Locate an
engine vacuum source and secure the open
end of the previously installed vacuum line.
*** NOTE ***
The vacuum source used should be non-ported
intake manifold vacuum.

*** NOTE ***
Some applications (depending on intake manifold
height) may require the reclocking of the supercharg-
er volute. If reclocking is required for your applica-
tion, loosen and remove the six 1/4-20 cap screws
and retaining plates that hold the compressor hous-
ing (volute) to the gearcase. If the compressor hous-
ing does not rotate freely relative to the gearcase, DO
NOT FORCE IT. SERIOUS SUPERCHARGER DAMAGE
MAY OCCUR. The machined mating surfaces are
designed to prevent pressurized air from escaping
and have minimal tolerances. If the housing will not
move or is very tight, contact Paxton Automotive
immediately at 888 9-paxton and ask our service
department for further assistance.
