NOTICES
(Read before installation is started)
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.
