A. Install the supplied T-bolt clamp onto the alu-
minum supercharger inlet duct oriented so as
to be accessible after the supercharger is
installed. Slide the inlet duct onto the super-
charger so that the cast contour lines up with
the discharge section of the volute. (See Fig.
14-a.)
B. Install the 1/8 NPT x -4 x 90° fitting into the
supercharger oil feed nozzle. (See Fig.
14-b.)
C. Attach the oil drain hose to supercharger
using stepless clamp pliers and tighten the
clamp making sure that it is oriented so that it
will have maximum clearance to the power
steering pump pulley after the supercharger
is installed. (See Fig. 14-b.)
D. Install a 2-3/4" sleeve onto the supercharger
discharge. Loosely attach the discharge tube
to the charge air cooler. The end of the tube
with the 1" bung must be nearer to the
charge cooler when installed. (See Fig. 14-c.)
E.
Install supercharger loosely with the oil drain
hose routed between the power steering pul-
ley and the frame rail. Start all four super-
charger mounting screws (3/8-16 x 1.75", 3/8-
16 x 3.00" and previously installed 2" screws)
and tighten.
F.
Trim as necessary and attach the super-
charger oil drain hose to oil pan. Tighten hose
clamp.
G. Route oil feed hose to supercharger and
attach.
H. Secure both the oil drain, oil feed and power
steering hoses from moving components
(steering shaft) and high heat areas (exhaust
14. SUPERCHARGER INSTALLATION
NOTE: If inlet duct does not slide onto volute easily, verify
that there are no burrs on its inside diameter and
then heat up the duct to ease assembly.

Fig. 14-c
NOTE: If the vehicle is equipped with ABS, verify that the
supercharger volute does not contact the module.
If contact will occur, sand the ABS module and/or
mounting bolt until there is minimal clearance.
NOTE: The oil drain hose MUST maintain a “downhill”
routing always. “Uphill" routing , Dips, kinks or
restrictions in the drain hose may cause super-
charger seal failure.
