See PDF2007 to 2009 model year 5.4L Shelby GT500 and 2005 to 2006 model year Ford Supercharged GTThe Whipple Supercharger Kit, part numbers WIK-5.4L-4VGT and WIK-5.4L-4VGT500, is a replacement supercharger for vehicles originally equipped with a stock supercharger. The kit includes a twin screw Whipple, new open element air filter with intake air tubing, 105mm mass air flow sensor, and a new ECM calibration. Maximum boost produced by the supercharger is around 16 pounds per square inch. No changes are made to the stock throttlebody or radiator thermostat and installation would not require any modification to any fuel or emission related tubing. Supercharger is designed to be a direct bolt-on replacement to the stock supercharger. The Whipple Pulley Kits, part numbers WIK-5.4L-4VPGT and WIK-5.4L-4VPGT500, utilize the stock supercharger and include a different size supercharger pulley, 105mm mass air flow sensor, new ECM calibration, and a new open element air filter with intake air tubing. Boost is increased to around 16 pounds per square inch. The new ECM calibration and/or programmer for both kits does not have any emission related user adjustments nor does it have capability to allow the user to upload new fuel and timing maps.

                              EXECUTIVE ORDER D—231—29

                       Relating to Exemptions Under Section 27156
                                  of the California Vehicle Code

                                Whipple Industries, Inc.
                          Whipple Supercharger and Pulley Kits

Pursuant to the authority vested in the Air Resources Board by Section 27156 of the
Vehicle Code; and

Pursuant to the authority vested in the undersigned by Section 39515 and Section 39516
of the Health and Safety Code and Executive Order G—02—003;

IT IS ORDERED AND RESOLVED: That the installation of the Whipple Supercharger and
Pulley Kits, produced and marketed by Whipple Industries, Inc. of 3292 N. Weber,
Fresno, California 93722, has been found not to reduce the effectiveness of the
applicable vehicle pollution control systems and, therefore, is exempt from the
prohibitions of Section 27156 of the Vehicle Code for the 2007 to 2009 model year 5.4L
Shelby G1T500 and 2005 to 2006 model year Ford Supercharged GT as listed in Exhibit A.

The Whipple Supercharger Kit, part numbers WIK—5.4L—4VGT and WIK—5.4L—4VGT500, is
a replacement supercharger for vehicles originally equipped with a stock supercharger.
The kit includes a twin screw Whipple, new open element air filter with intake air tubing,
105mm mass air flow sensor, and a new ECM calibration. Maximum boost produced by
the supercharger is around 16 pounds per square inch. No changes are made to the
stock throttlebody or radiator thermostat and installation would not require any
modification to any fuel or emission related tubing. Supercharger is designed to be a
direct bolt—on replacement to the stock supercharger.

The Whipple Pulley Kits, part numbers WIK—5.4L—4VPGT and WIK—5.4L—4VPGT500, utilize
the stock supercharger and include a different size supercharger pulley, 105mm mass air
flow sensor, new ECM calibration, and a new open element air filter with intake air tubing.
Boost is increased to around 16 pounds per square inch.

The new ECM calibration and/or programmer for both kits does not have any
emission related user adjustments nor does it have capability to allow the user to
upload new fuel and timing maps.

This Executive Order is valid provided that the installation instructions for the Whipple
Supercharger and Pulley Kits will not recommend tuning the vehicle to specifications
different from those of the vehicle manufacturer.

Changes made to the design or operating conditions of the Whipple Supercharger and
Pulley Kits, as exempt by the Air Resources Board, which adversely affect the
performance of the vehicle‘s pollution control system shall invalidate this Executive Order.


                                              2.


This Executive Order shall not apply to any Whipple Supercharger and Pulley Kits
advertised, offered for sale, sold with, or installed on a new motor vehicle prior to or
concurrent with transfer to an ultimate purchaser.

Marketing of the Whipple Supercharger and Pulley Kits using any identification other than
that shown in this Executive Order or marketing of the Whipple Supercharger and Pulley
Kits for an application other than those listed in this Executive Order shall be prohibited
unless prior approval is obtained from the Air Resources Board.

This Executive Order does not constitute any opinion as to the effect the use of the
Whipple Supercharger and Pulley Kits units may have on any warranty either expressed
or implied by the vehicle manufacturer.

This Executive Order is granted based on submitted emission test data generated on a >
2007 model year 5.4L Ford Shelby GT500 certified to the Low Emission Vehicle II Low
Emission Vehicle (LEV II LEV) emission standards and modified with the replacement
Whipple Supercharger Kit, part number WIK—5.4L—4VGT500 using the 2.3L compressor
and the 2.625 inch diameter supercharger pulley. Test results on the Shelby GT500
showed that emission levels, with Whipple Industries, Inc.‘s Whipple Supercharger
installed, met the applicable emission standards when tested using the Cold—Start
CVS—75 Federal Test Procedure (FTP) and the Supplemental Federal Test Procedure
(SFTP USO6/S5C03) test cycles. Boost pressure was measured at 16 pounds per square
inch, stock is rated at 9 pounds per square inch. Examination of the OBD II system
showed the Whipple Supercharger did not affect OBD II system operation. Results from
emission testing conducted at the Roush Emissions Laboratory, Livonia, Michigan are
listed below with deterioration factors applied.
