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 utes of a 3/8 NPT tap with grease.
Tap the hole until the tting 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 tting.
Install the supplied 90° elbow and 3/8 NPT x
1/2” barb tting pointing forward and slightly
up.
E. Route the oil drain hose from the supercharger
to the barb tting, attach and tighten the hose
clamp. (See Fig. 5-a.)
5. OIL DRAIN LINE (ENGINE OIL-FED KITS ONLY. APPLICATIONS WITH
V-3 SUPERCHARGER SKIP AHEAD TO STEP 7)
IMPORTANT!: Oil in the supercharger is gravity
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.
