1. To provide an oil drain for the supercharger,
it is necessary to make a hole in the side of
the oil pan. The drain fitting location MUST
allow the oil to drain back ABOVE the oil
level in the pan.
2. Locate the forward-most oil pan bolt on the
driver side of the engine block.
3. From the center of that bolt, measure 2.5”
toward the rear of the pan and mark the pan
for the oil return line fitting. See Fig 4A.
4. Drill 1/8" pilot hole at the marked location.
5. Use the supplied 9/16" Roto-Broach to drill
hole in oil pan. Break through pan carefully
so the cut out piece does not go into the pan
6. Thread the hole with a 3/8" NPT tap to
approximately 1/2" deep or until fitting can be
started. Pack the flutes of the tap with heavy
grease to hold any loose chips.
7. Thoroughly clean the threaded area. Reach
inside oil pan and retrieve any stray chips.
8. Install the 3/8" NPT to 1/2" barb fitting into
the tapped hole. Temporarily cover oil drain
barb fitting to keep out debris.
9. Drain the engine oil, install a new filter and
refill with fresh oil.
10. Remove the blue plastic shipping cap from
the 1/2" drain fitting on the supercharger
Attach the supplied fabric braided 1/2" oil
return line to the 1/2" fitting and secure with
#8 Hose Clamp.
NOTE: Oil drain hose must be routed downhill with mini-
mal bends and no kinking. The supercharger
relies on a free-flowing gravity drain for proper
operation. Uphill hose routing will result in
improper drainage and possibly supercharger
failure.
4. OIL DRAIN INSTALLATION
(ENGINE OIL-FED UNITS ONLY)
Fig 4A
NOTE: Mark the hole for drilling so that it is as close to
the top of the pan as possible, while still allow-
ing enough clearance to install the fitting so that
it clears the rail on the pan.
