Included in this kit is an 8-rib supercharger pulley that may be smaller than the one originally
supplied. This new pulley is recommended to achieve the best performance results. Removal of
the factory sealed pulley will reduce the supercharger warranty from three years to one year
unless the supercharger unit (with the original pulley still attached) and new pulley are sent into
Vortech for removal, installation and re-sealing. If the supercharger warranty is not a concern or
if the supercharger warranty has expired, the pulley may simply be removed and replaced with
the new part supplied. Hammering/prying etc. on the supercharger and/or pulley will cause
damage to the parts. Light heating of the supercharger pulley with a propane torch (if the pulley
is tight on the shaft) will aid removal. A return authorization number is required before the
supercharger and pulley are sent into Vortech. Call the Vortech service department at (805) 2470226 for a return authorization number. Return freight (ground) will be paid by Vortech.

IMPORTANT
• Custom ECM programming and fuel / ignition system upgrades will be required when
changing the supercharger drive pulley to any size other than what was originally supplied
in the complete supercharger kit.
• Supercharger pulley removal may reduce or void the supercharger unit warranty.
• Pulley Diameter Changes: Careful size selection is mandatory for proper engine and super-
charger longevity. Contact the applicable Vortech and Paxton tech line for assistance with
impeller speed calculations if necessary.
• A Vortech Maxflow Race or Mondo compressor bypass valve is required for applications
producing more than 11-12 psig.
A. Disconnect the battery.
B. Locate the coolant drain plug on the passenger’s
side of the radiator. Next drain the coolant into a
clean container. This coolant will be reused in a
later step.
C. Remove the bolts securing the coolant overflow
reservoir to the plastic fan shroud. (See Fig. 1-a.)
D. Loosen the hose clamps securing the super-
charger discharge tube/cooler from the supercharger. Disconnect the by-pass valve hose(s)
where they connect to the inlet and discharge
tubes. Disconnect the by-pass valve vacuum
lines where it connects at the fuel rail. Set the
by-pass valve(s) aside to be reinstalled in a later
step. Remove the discharge tube or tubes/airwater cooler (if equipped), and set aside, to be
reinstalled in a later step.
E. Loosen the hose clamps securing the inlet duct
to the supercharger. Remove the inlet duct
assembly and set it aside to be reinstalled in a
later step
F. Disconnect the oil feed and oil drain lines.

NOTE: Temporarily cap the oil lines to protect
your engine from foreign particles.
G. Loosen the alternator and water pump pulley
retaining hardware.
H. Using a 1/2" ratchet loosen the accessory belt
tensioner and remove the belt from the supercharger pulley.
I. Remove the four screws that secure the super-
charger mounting bracket to the front of the
engine. Set the supercharger/bracket assembly
on a clean flat work surface with the drive pulley
facing up.
NOTE: Refer to Fig. 2-c on Page 3, for the next few
steps.
A. Remove the original 6-rib supercharger pulley
from the supercharger and install the supplied
8-rib pulley (2A038-333) and secure using the
provided retainer assembly (8R101-002).
NOTE: This kit may include a smaller than originally sup-
plied supercharger pulley. Removal of the factory
sealed pulley will reduce the supercharger warranty
from three years to one year unless the supercharger unit (with the original pulley still attached) and
new pulley are sent into Vortech for removal, installation and re-sealing. If supercharger warranty is
not a concern or if the supercharger warranty has
expired, the pulley may simply be removed and
replaced with the new part supplied. Hammering/
prying etc. on the supercharger and/or pulley will
cause damage to the parts. Light heating of the
supercharger pulley with a propane torch (if the
pulley is tight on the shaft) will aid removal. A
return authorization number is required before the
supercharger and pulley are sent into Vortech. Call
the Vortech service department at (805) 247-0226
for return authorization number. Return freight
(ground) will be paid by Vortech.
B. Remove the smooth (steel) idler pulley located
on the supercharger mounting bracket and
retain the hardware. Install one of the supplied
.875"OD x .663"ID x .140" thick spacers (2A017882-01) and Ø3.0" smooth aluminum idler
(4FU116-031) provided. Secure using the hardware previously removed. (See Fig. 2-b.)
NOTE: The snap-ring that retains the bearing
in the idler should be facing the
engine.
F. Using a 10mm socket, remove the
retaining screw securing the A/C pulley outer clutch. Remove the snap
ring that retains the factory A/C pulley. Remove and replace the factory
pulley with the 8-rib A/C pulley
(4FR016-021) provided. Secure using
the factory snap-ring. Reinstall the
outer clutch using the factory 10mm
headed screw previously removed.
G. Remove the spring tensioner retain-
ing screw and tensioner. Replace the
spring tensioner pulley using one of
the supplied .875"OD x .663"ID x
.140" thick spacers and Ø3.0" smooth
steel idler (4FL116-170) provided.
Locate the .280" thick spring tensioner spacer and Pilot (4FL017-011 &
4FL017-021). Reinstall the spring tensioner assembly using the factory
retainer and the tensioner spacer
and pilot provided. (See Fig. 2-g for
pulley orientation).
8-RIB S/C PULLEY
INSTALLED
NOTE: The snap-ring that retains the bearing in
the idler should be facing the supercharger mounting bracket.
C. Remove the factory alternator pulley. Install the
supplied Ø2.5" 8-rib alternator pulley and secure
using the factory retaining nut.
D. Remove the smooth idler located just above the
spring tensioner and retain the hardware to be
reinstalled. Replace with one of the supplied
.875"OD x .663"ID x .140" thick spacers (2A017882-01 and Ø3.0" smooth alumiinum idler
(4FU116-031) provided. Secure using the hardware previously removed.
NOTE: The snap-ring that retains the bearing in
the idler should be facing the engine.
E. Replace the 2.6" 6-rib idler located above the
A/C compressor, using a .875"OD x .663"ID x
.140" thick spacers (2A017-882-01) and Ø2.6"
8-rib idler pulley (4FL116-160) supplied.

H. Remove the crank pulley retaining
screw. Using the appropriate crank
pulley/puller, remove the factory
crank pulley. Locate and install the
8-rib crank pulley (4FR016-041) provided. Secure using the factory
retaining screw.
NOTE: A small amount of grease on the
sealing surface of the pulley is recommended. Also a small amount
of silicone sealant should be used
on the bore of the pulley and
threads of the retaining screw.
I. Remove the previously loosened
water pump pulley retaining hardware.
Replace the water pump pulley with the
appropriate pulley provided and secure
using the factory hardware.
NOTE: Two water pump pulleys are provided in
this up-grade. 2000-2002 1/2 will use the
4FK016-081 steel pulley, while 2002 1/2
+ 2004 will use the 4FR016-051 aluminum pulley.
J. Using the appropriate power steering pul-
ley puller, remove the factory P/S pulley.
Locate the 8-rib P/S pulley (4FR016-031)
provided and install using the appropriate
pulley installer. (See Fig. 2-d.)
NOTE: The end of the P/S pump shaft should be
Fig. 2-d
flush with the end of the pulley when
properly installed. (See Fig. 2-d.)
provided using Fig. 2-c for belt route reference.
NOTE: Not all pulleys are installed at this
time
B. Refer to Fig. 3-a for hardware and spacer
placement and loosely install the supercharger/bracket assembly. Take care to
route the drive belt properly. Make sure
the bracket and spacers mount flush
against their mounting surfaces.
C. Tighten the supercharger mounting
assembly at this time.
D. Using a 1/2" ratchet, release tension from
the factory belt tensioner and install the
8-rib drive belt. Release the tensioner and
confirm that the belt is in place and the
tensioner is within operating range.
