STOP
T his manual provides information on the installation, maintenance and service of the
Vortech supercharger kit expressly designed for this vehicle. All information, illustra-
tions and specifications contained herein are based on the latest product information
available at the time of this publication. Changes to the manual may be made at any time
without notice. Contact Vortech Engineering for any additional information regarding this kit
and any of these modifications at (805) 247-0228 8:00am-4:30pm PST.
NOTICE
Due to variances in each vehicle, Vortech recommends that the vehicle get
a “custom tune” from a local, reputable tuner.
This kit is supplied with a “universal” fuel and ignition timing calibration. This
calibration is intended to allow the vehicle to start and operate at part throt-
tle, and is not optimized for full throttle performance. Do not operate the
vehicle at heavy throttle or high RPM until a custom calibration tailored for
your specific vehicle can be obtained from a competent tuner. A “wide-
band” exhaust oxygen sensor must be used to confirm proper air/fuel ratio.
Vortech suggests a proper WOT air/fuel ratio range of 10.8-11.0:1 for 91
octane fuel.
