upper edge of the horizontal slots in the bracket.
Slide the supercharger towards the firewall as far
as it will go. Tighten down the two pinch bolts
using an open-end wrench. If you find that the
bracket/supercharger assembly collides with your
cam cover vent tube during initial installation, it
means you did not leave enough threads
exposed on the two main mounting bolts
installed in step #6.1. Retry it with the bolts fur-
ther out.
6.3 Swing the flat lower bracket up into place in
front of the supercharger boss. Locate the small
stamped throttle cable bracket from your kit and
thread the new bolt through the throttle cable
bracket hole, through the supercharger boss and
through the flat steel lower bracket. Secure with
the locking nut and bolt supplied. Make sure that
the head of the bolt is on the throttle bracket side
of the assembly. Leave the power steering pump
long bolt and nut finger tight (14mm heads).
6.4 Route your throttle cable so that it is looped
back toward the firewall, routing the cable just
behind the driver’s side headlamp motor. Install
the cable’s threaded end into the small bracket
attached to the underside of the supercharger.
Make certain that the cable/grommet is fully nest-
ed within the slot (this may require some muscle -
we made it tight so your throttle cable won’t ever
fall out). Open the throttle by hand and insert the
cable end into the throttle spool. Make sure that
the cable runs in the center of the groove of the
throttle spool. If it does not, adjust the throttle
cable bracket left or right until it is centered in the
spool’s groove. Have an assistant operate the gas
pedal multiple times to confirm that the action is
free and easy without binding or interference.
Make sure that the cable has a bit of “sloppy”
slack with the gas pedal released and that full
throttle is available when the gas pedal is fully
depressed. If it does not “flop” in the idle position,
you will have trouble setting your idle speed.
Make sure that the cable is run in such a way as
to allow for engine movement from side to
side.Make very certain that all throttle cable-
mounting points are secure - this installation area
is critical for safe operation of your car. This brack-
etry has been carefully designed for correct opera-
tion. It is your responsibility as the installer to
ensure that it is bolted together successfully with-
out binding or interference.
7.0 AIRFLOW METER WORK
7.1 Locate the new air filter base from your kit and
install it to the air flow meter intake port, reusing the
Mazda cork gasket and four nuts. The air flow meter
is offset toward the top of the air filter base. The
seven pin electrical connector on the airflow meter
faces upward.
7.2 Locate the driver’s side shock tower support and
notice the Mazda air filter box mounting bracket
(painted body color) on the forward edge. This verti-
cal bracket is held in place by a horizontal bolt (also
