TROUBLESHOOTING
SYMPTOM: Engine cranks but will not start.
PROBABLE CAUSES: Airflow meter disconnect-
ed; Idle air line open; Low battery voltage.
CURE: Double check that the connector to air-
flow meter is well connected. Re-check the 3/4”
ICS line and the PCV line to see that they are
not leaking. Use a known good battery to “jump”
the Miata’s battery. It is possible to have enough
voltage to crank a Miata but not enough to cor-
rectly run the engines control computer.
SYMPTOM: No power during boost.
PROBABLE CAUSES: Cross over tube loose.
CURE: Check the cross over tube to see that it is
well connected at both ends. Check electrical
connections,
SYMPTOM: Unstable Idle.
PROBABLE CAUSE: Idle airscrew set incorrect-
ly; Restrictor left out in step #7.8; air leak in
intake track.
CURE: Re-check restrictor. Check idle adjust-
ment procedure in step 8.1 above. Check for air
leaks - vacuum at idle should be at least 17.7 in
Hg.
11.0 FURTHER MODIFICATIONS
Now that your Miata has a stronger engine, there
are a few changes you might want to make to
the rest of the car to improve its performance.
The following are not required for your super-
charged Miata, but are presented as tuning hints
for a better all-around car. When it comes time to
put in a new clutch, we recommend the Jackson
Racing Stage 1 clutch kit. While your new super-
charger and the standard Mazda clutch work well
together, it is a good idea to step up to the
Jackson Racing unit when you are changing your
clutch. Now is the time to upgrade your suspen-
sion. Jackson Racing sway bars will tighten your
steering response. A set of Jackson Racing Sport
lowering springs will lower the car 25mm and
make for better handling without the harsh ride of
competition springs. Have your car aligned after-
ward (driver’s equivalent weight in the driver’s
seat) to factory specifications after any suspen-
sion changes. A performance muffler will make
your supercharged Miata that much faster. Since
you are now flowing 300 cubic feet per minute
through a muffler designed for 177 cfm, an
improvement can be made.
WARRANTY
The supercharger unit itself carries a 2 year or
100,000 mile warranty (for the original purchaser
of the kit) against defects in material and work-
manship. No other warranties apply. This warran-
ty is void if the subject vehicle is used in any rac-
ing activities of any sort.
HELP
If you experience any problems with your kit dur-
ing installation or operation, contact your retailer
or Moss Motors at 888-888-4079.
