A. To provide an oil drain for the supercharger, it is

necessary to make a hole in the oil pan. Locate

and centerpunch the hole per Fig. 5-a. Drill a

1/8” pilot hole at center location.

B. Use the supplied 9/16” rotobroach to drill the

hole in the oil pan. Take care to break through

the pan gently and remove the cut out.

C. Pack the flutes of a 3/8 NPT tap with grease.

Tap the hole until the fitting can be started.

D. Thoroughly clean the threaded area. Reach

inside the oil pan and retrieve any stray chips.

Apply a small amount of sealer to the new

threads. Apply more sealer to the supplied 3/8”

NPT hex nipple and secure in the hole. Make

sure the seal is formed all around the fitting.

Install the supplied 90° elbow and 3/8 NPT x

1/2” barb fitting pointing forward and slightly

up.

E. Route the oil drain hose from the supercharger

to the barb fitting, attach and tighten the hose

clamp. (See Fig. 5-a.)

drained to the oil pan. Trim the sup-

plied oil drain hose as necessary so

that it is continuously sloping down

towards the oil pan. Avoid dips,

kinks etc.
