3. OIL DRAIN (Engine oil fed kits only. V3 kits, skip

ahead to section 5)

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

to make a hole in the oil pan. Locate and mark hole per

diagram. It is best to punch the hole rather than drill.

B. Remove paint around the hole area.
C. Use a small center punch to perforate the pan and expand

hole. Switch to a larger diameter punch and expand the hole

further to approximately 9/16" diameter. Most punches are

made from hexagon material and may be placed in a socket

with an extension to make this procedure easier.

D. Tap the hole with a 3/8" NPT tap approximately1/4" deep.

Pack the flutes of the tap with heavy grease to hold chips.

Use a small magnet to check for any stray chips.

E. Thoroughly clean the threaded area. Apply a small amount

of silicone sealer to the new threads. Apply more sealer to

the 3/8" NPT hose fitting and secure in hole. Make sure a

seal is formed all around the fitting.

F. Drain the engine oil and change the filter.

4. OIL FEED LINE (Engine oil fed kits only. V3

kits, skip ahead to section 5)

A. Remove the oil pressure sender and mounting

boss fitting from the engine. These are found on

the engine's left side just ahead of the oil filter.

B. Thread the supplied 3" x 1/4" NPT nipple into the

block using engine oil on the threads. Pipe tape,

paste or other sealant is not recommended as it

might loosen and cause blockage of the oil feed

orofice, resulting in supercharger failure.

C. Thread the supplied 1/4" female TEE into the

nipple. Rotate the TEE so that the center leg

points toward the front of the vehicle. Thread

the 45° elbow into the leg of the TEE pointing

toward the side of the vehicle.

D. Install the factory sending unit into the 45°

elbow.

E. Thread the supplied flare fitting into the remaining

leg of the TEE.

F. Connect the red oil feed line to the fitting at the

pressure sender and route it behind the A/C

mounting plate to the supercharger location.

Cover the end of the hose with a clean plastic

bag. Connect the line to the supercharger with

the flare fitting provided.

NOTE: This method of rolling over the lip of the hole and

tapping it works very well if carefully done and

should cause no problems.
