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.

grease to hold any loose chips.

7. Thoroughly clean the threaded area. Reach

inside oil pan and retrieve any stray chips.

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.

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.
