SUPERCHARGER INSTALLATION

A. Attach the 1/2” oil drain hose to the supercharger

and secure with the #8 hose clamp.

B. Route the hose down the rear of the main bracket

while lowering the supercharger into the proper
mounting location on the plate. Be sure that the oil
drain hose remains unkinked with smooth bends.
(See

Fig. 5-a

C. Using the five supplied 3/8-16 x 1” bolts and AN

washers, secure the supercharger to the mounting
plate.

D. Route the oil drain hose around the main casting

and down to the fitting in the oil pan. Make sure that
the hose runs below the positive alternator lug, but
still remains running “downhill”. It is very important
that the oil drain hose is free from restrictions, tight
bends, kinks or any other drain obstructing conflict.
Route the hose away from direct exhaust heat. Trim
hose length if necessary and secure to the oil pan
with the supplied #8 hose clamp.

Attach the 1/8 NPT x 45

brass fitting to the super-

charger oil feed. Use a 1/2” wrench to hold the feed
fitting while tightening the 45

fitting. Attach the oil

feed hose to the supercharger.

Using the tie wraps provided, secure the feed and
drain systems away from heat and/or sharp objects.

G. Using the supplied spacer, bolt and dust shield,

mount the supplied 3" idler pulley (non-flanged) to
the boss on the supercharger. (See

Fig. 4-b

NOTE: Before the supercharger can be in-

stalled onto the bracket, it will be
necessary to carefully bend the
aluminum air conditioning line
running over to the passenger
side of the vehicle. A minor bend
pushing the line toward the rear
is all that is required.

WARNING: The oil system contains a small

orifice that is easily plugged.
Do not use any type of sealant
on any of the threads. Instead,
use clean engine oil. Disas-
semble and blow out the entire
line if there is any question.
