b. The screw just above the A/C compressor

c. The screw between the A/C compressor and the crankshaft

3. SUPERCHARGER ASSEMBLY PREPARATION AND INSTALLATION

C. Inspect the supercharger mounting plate/idler pulley assembly and familiarize yourself with its components and configuration. The new belt should be routed so that the ribbed side engages the ribbed idler pulley and the smooth side rides on the other pulleys. Note the multiple mounting locations of the ribbed idler, used to compensate for different supercharger pulley sizes and belt lengths. All four (4) idler mounting bolts should be left slightly loose during installation to facilitate alignment. (See Fig. 3.1 and Fig. 3.2 Belt Routing Diagram later in this section)

D. Thread the two (2) included M8 x 200mm studs into the lower two engine cover fastener holes, in the locations of the previously-removed fasteners (one just above the A/C compressor and one between the A/C compressor and the crankshaft). Use a small amount of blue thread lock on the threads. Leave approximately 6" of stud exposed.

E. Slide a .875” x 2.058” spacer over the stud above the A/C compressor. See Fig. 3.1 near the end of this section for this and all other mounting bracket spacer and fastener locations.

F. Slide a .875” x 2.146” spacer over the stud between the A/C compressor and the crankshaft.

G. With the thinner steel plate closer to the engine, begin to slide the mounting bracket assembly over the studs. Place a .875” x 2.730” (.323 I.D.) spacer over each stud, sandwiched between the two mounting plates.

H. Place a 5/16” flat washer over the open end of each stud and secure with an 8mm flange head nut. Adjust stud exposed length as needed so 1-2 threads protrude beyond the nut. Do not tighten at this time.

I. Locate the .875” x 1.928” spacer and M8 x 80mm hex head screw. Place a 5/16” flat washer on the screw and pass it through the outer (3/8" thick) plate and .875” x 1.928” spacer into the threaded boss on the engine cover in the location furthest toward the passenger side. Do not tighten at this time.

J. Locate the remaining .875” x 2.058” spacer and M8 x 100mm button head screw. Pass the screw through the inner (1/4" thick) plate (with no washer) and .875” x 2.058” spacer into the uppermost engine cover hole from which an OEM screw was previously removed (2nd hole from the top overall). Do not tighten at this time.

k. Tighten the four (4) idler pulley mounting bolts. Ensure that the second-highest bolt has the thin washer (the others have standard-thickness washers).

l. Confirm that the four (4) screws and two (2) studs securing the supercharger assembly to the engine are properly aligned. Tighten them in progressive steps in an alternating sequence.

M. Engine Oil Fed Units Only: Locate the included length of black braided 1/2" oil drain hose. Remove the shipping cap from the 1/2" barbed oil drain fitting on the bottom of the supercharger and attach the drain hose with the included #8 worm gear clamp.

N. Place the supercharger into the cradle of the outer mounting plate, aligning the five (5) mounting holes, with the pulley toward the engine and the discharge pointing straight down. Secure the supercharger to the plate with five (5) 3/8-16 x 1.25 hex head screws with washers. Route the braided drain hose (if equipped) directly downward, away from moving parts and sharp edges, and secure.

O. Align the 6-rib drive belt according to the diagram shown at the end of this section. The belt routing is almost identical to the OEM routing with the exception of the portion that passes between the water pump pulley and crankshaft pulley to drive the supercharger. Ensure that the belt routes smoothly over the supercharger pulley and all of the new idler pulleys as well as the OEM engine accessories.

P. Use a 15mm wrench to rotate the OEM belt tensioner counter-clockwise and install the belt. Depending on pulley size, it may be necessary to adjust the location of the ribbed supercharger idler pulley to achieve proper belt tension. Ensure that the belt wraps smoothly around each of the pulleys and that all ribbed pulleys are properly engaging the belt's ribs.

Q. Locate the supplied 1.25” black anodized aluminum throttle body spacer. Install the included large O-ring into the groove in the spacer -- this O-ring seals against the throttle body, and the smooth side of the spacer seals against the OEM O-ring in the intake manifold. Reinstall the throttle body, rotated 180° from its original orientation (upside-down), using this spacer, the four (4) included M6 x 80mm socket head cap screws, and four (4) included 6mm washers. Ensure that both O-ring seals stay in place. The OEM evaporative emissions tube connecting to the solenoid on the intake manifold just behind the throttle body will have to be slightly bent. (See Fig. 3-d)

12. OIL DRAIN INSTALLATION (OIL-FED UNITS ONLY)

NOTE: To provide an oil drain for the supercharger, it is necessary to make a hole in the oil pan. It is best to punch the hole rather than to drill it.

A. Locate the wiring harness secured to the front edge of the oil pan. Remove the two (2) 10mm nuts securing the wiring harness mounting brackets (one on each side of the crankshaft), allowing the harness to be pulled downward for improved access to the front face of the oil pan. (See Fig. 12-a)

B. Mark the location for the oil drain fitting on the smooth portion of the front face of the oil pan toward the passenger side, approximately 5/8" down from the oil pan mounting flange. (See Fig. 12-b; also see Fig. 12-1 at the end of this section)

C. Remove paint from the area around the hole location.

D. Use a small center punch to perforate the pan and expand the hole. Switch to a larger diameter punch and expand the hole further to approximately Ø9/16". Most punches are made from hexagon material and may be placed in a socket with an extension to make this procedure easier. (See Fig. 12-d)

E. Tap the hole with a 3/8" NPT tap approximately 1/4" deep. Pack the flutes of the tap with heavy grease to hold chips. Use a small magnet to check for any stray chips.

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.

F. Thoroughly clean the threaded area. Apply a small amount of silicone sealer or Teflon paste to the new threads. Apply more sealer to the included 3/8" NPT hose barb fitting and install the fitting into the hole, making sure a seal is formed all around the fitting.

G. Change the engine oil and filter to flush out any contaminants that may have entered the oil pan.

H. Locate the oil drain hose previously attached to the barb fitting on the bottom of the supercharger. Trim the hose to length and secure to the barbed drain fitting on the front of the oil pan with an included worm gear clamp.

NOTE: Use extra care to secure the drain hose away from moving parts and sharp edges. It is important that the hose travels downhill for its entire length.

I. Resecure the wiring harness running in front of the oil pan, using the included brass spacers to relocate the harness downward for drain hose clearance. (See Fig. 12-i)

13. REFLASH COMPUTER

IMPORTANT! To ensure trouble-free programming of your vehicle's computer:
