NOTE:

It may help to pack the cutting tool with

grease to help prevent and stray chips from

entering the oil pan.

C. Thread the hole with a 3/8"NPT tap to

approximately 1/2" deep or until the oil drain-

fitting can be started. Pack the flutes of the

tap with grease to minimize the amount of

debris that gets into the engine. Access is

restricted so inserting the tap in a socket and

then using a ratchet to rotate it is helpful.

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

is necessary to make a hole in the oil pan.

Mark the hole location by measuring 1-1/8”

from the bollt as shown on the front of the

pan, and 1-1/8” down from the oil pan mount-

ing rail on the engine block. Center-punch the

hole location to be drilled. (See Fig. 3-a.)

B. Drill a 1/8" pilot hole at the previously marked

location. Use the supplied 9/16" cutter to

enlarge the pilot hole, making sure to break

through easily. Do not stop the drill motor

until the cutter has been extracted so that the

cutout does not fall into the pan.

3. OIL DRAIN INSTALLATION (ENGINE OIL-FED kITS ONLY. APPLICATIONS WITh

V-3 SUPERChARGERS SkIP AhEAD TO STEP 5)

NOTE:

When tapping the hole be careful not to bot-

tom out the tap. If the tap does bottom

before the thread is large enough you will

need to trim the end of the tap to facilitate a

deep enough thread cut.

D. Thoroughly clean the threaded area. Apply a

small amount of silicone sealer or teflon

paste to the threads of the supplied 3/8"NPT

hose fitting and secure in the hole. Make sure

a seal is formed all around the fitting.

Drain the engine oil and remove the oil filter.

Replace the oil filter and refill the engine with

oil.

LOCATION

TO BE DRILLED

NOTE:

so a low profile or right angle drill may be

necessary.
