1996 through 2008 Ford vehiclesThe Whipple Supercharger kit, part number WIK-4.6L-3V-IC and WIK-4.6L-3V, consists of the following main components: 2.3L Twin Screw Whipple supercharger using a 3.125 to 4.0 inch diameter pulley, intercooler, intake manifold, bypass valve, 160 degree thermostat to replace the stock thermostat, fuel pump, reflashed ECM, mass air flow sensor, a set of high flow injectors, and an open element air filter on 2005 model year Mustangs built after April 30, 2005 and 2006 model year Mustangs only. The stock air cleaner housing with the hydrocarbon adsorber on 2005 model year Mustangs built on or before April 30, 2005, and 2007 and 2008 model year Mustangs is retained but modified with a new air cleaner housing bottom, a new high flow filter and an air cleaner housing lid modified to accept the mass air flow (MAF) extension. The breather hose may be replaced with an SAE30R9 rated hose. Boost is limited to a maximum of 13 psi. The stock crankshaft pulley and throttle body are retained during installation. The Whipple Charger kit, for other Ford vehicles, consists of the following main components: Twin Screw Whipple supercharger, intake manifold, bypass valve, 160 degree thermostat to replace the stock thermostat, new air cleaner housing with a high-flow element, fuel pump, reflashed ECM, mass air flow sensor, and a set of high flow injectors. Some kits may include an intercooler. The breather hose may be replaced with an SAE30R9 rated hose.

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 AhlD RESOLVED: That the installation of the Whipple Supercharger,
manufactured and marketed by Whipple Industries, Inc., 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 Ford Motor Company vehicles listed in Exhibit A.

The Whipple Supercharger kit, part number WIK-4.6L-3V-IC and WIK-4.6L-3V, consists of the
following main components: 2.3L Twin Screw Whipple supercharger using a 3.1 25 to 4.0 inch
diameter pulley, intercooler, intake manifold, bypass valve, 160 degree thermostat to replace
the stock thermostat, fuel pump, reflashed ECM, mass air flow sensor, a set of high flow
injectors, and an open element air filter on 2005 model year Mustangs built after April 30, 2005
and 2006 model year Mustangs only. The stock air cleaner housing with the hydrocarbon
adsorber on 2005 model year Mustangs built on or before April 30,2005, and 2007 and
2008 model year Mustangs is retained but modified with a new air cleaner housing bottom, a
new high l'low filter and an air cleaner housing lid modified to accept the mass air flow (MAF)
extension. The breather hose may be replaced with an SAE30R9 rated hose. Boost is limited
to a maximum of 13 psi. The stock crankshaft pulley and throttle body are retained during
installation.

The Whipple Charger kit, for other Ford vehicles, consists of the following main components:
Twin Screw Whipple supercharger, intake manifold, bypass valve, 160 degree thermostat to
replace the stock thermostat, new air cleaner housing with a high-flow element, fuel pump,
reflashed ECM, mass air flow sensor, and a set of high flow injectors. Some kits may include
an intercooler. The breather hose may be replaced with an SAE30R9 rated hose.

This Executive Order is valid provided that the installation instructions for the Whipple
Supercharger will not recommend tuning the vehicle to specifications different from those
submitted by the device manufacturer.

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


This Executive Order shall not apply to any Whipple Supercharger 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 using any identification other than that shown in this
Executive Order or marketing of the Whipple Supercharger 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 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 4.6L Ford Mustang certified to the Low Emission Vehicle II Ultra Low Emission
Vehicle (LEV II ULEV) emission standards and modified with the Whipple Supercharger Kit,
part number WIK-4.6L-3V-IC using the 2.3L compressor and the 3.125 inch diameter
supercharger pulley. Test results 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 US06lSC03) test cycles. Boost pressure was measured at 13 psi.
Examination of the OBD II system showed the Whipple Supercharger did not affect OBD II
system operation. R e s ~ ~ lfrom
