                                     EXECUTIVE ORDER D—423—1
                               Relating to Exemptions Under Section 27156
                                            of the Vehicle Code


                                  ALLEN ENGINE DEVELOPMENT
                                    6 PSI. SUPERCHARGER KIT


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—45—9;

IT IS ORDERED AND RESOLVED: That the installation of the 6 PSI. Supercharger Kit, manufactured
and marketed by Allen Engine Development, 255 Lambert Street, Unit #1, Oxnard, California 93030 has
been found not to reduce the effectiveness of the applicable vehicle pollution control system and,
therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for the following Ford
4.6/5.4 liter applications excluding any vehicle certified to a transitional low emission vehicle (TLEV) or
low emission vehicle (LEV) emission standard: 1994/95 Crown Victoria, Grand Marquis, Town Car,
1994—97 Thunderbird/Cougar, 1996—98 2—valve Mustang, and 1997/98 trucks.

The following 1998 model—year engine families certified to the TLEV or LEV emission standard are
excluded from this Executive Order: Ford vehicles, WFMXVO4.6DBA (Mustang) and
WFMXAO05SAJGC (Trucks).

The 6 PSI. Supercharger Kit includes the following main components: Eaton supercharger with a 2.85"
diameter pulley (passenger cars) or 2.94" diameter pulley (trucks), intake manifold plenum, intake
manifold runners, intercooler, throttle body adapter, electric water pump, high flow fuel pump, and fuel
pressure regulator. The EGR valve is relocated between the throttle body and the supercharger intake.
Stock air cleaner is maintained.

This Executive Order is valid provided that the installation instructions for the supercharger 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 supercharger, as exempt by the Air Resources
Board, which adversely affect the performance of the vehicle‘s poliution control system shall invalidate
this Executive Order.

Marketing of the supercharger using any identification other than that shown in this Executive Order or
marketing of the 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. Exemption of the
supercharger shall not be construed as exemption to sell, offer for sale, or advertise any component of the
kit as an individual device.

This Executive Order does not constitute any opinion as to the effect the use of the supercharger may
have on any warranty either expressed or implied by the vehicle manufacturer.


ALLEN ENGINE DEVELOPMENT                                              EXECUTIVE ORDER D—423—1
6 PSI. SUPERCHARGER KIT                                               (Page 2 of 2)

 This Executive Order is granted based on submitted emissions test data that was generated during a Cold
 Start CVS—75 Federal Test Procedure in the modified configuration. Emissions test data showed that the
Allen Engine Development‘s 6 PSI. Supercharger Kit did not adversely affect tailpipe emissions during
the Cold Start CVS—75 Federal Test Procedure. However, the ARB finds that reasonable grounds exist to
believe that use of the Allen Engine Development‘s Supercharger Kit may adversely affect emissions of
 motor vehicles when operating under conditions outside the parameters of the previously prescribed test
procedures. Accordingly, the ARB reserves the right to conduct additional emission tests, in the future,
 as such tests are developed, that will more adequately measure emissions from all cycle phases. If such
test results demonstrate that the supercharger adversely affects emissions during off—cycle conditions
 (defined as those conditions which are beyond the parameters of the Cold—Start CVS—75 Federal Test
«Procedure), this Executive Order shall be effectively rescinded as of the date the test results are
 validated. Further, if such test results or other evidence provides the ARB with reason to suspect that the
 supercharger will affect the durability of the emission control systems, Allen Engine Development shall
be required to submit durability data to show that the durability of the vehicle emission control system is
not, in fact, affected and/or that the add—on or modified part demonstrates adequate durability.

in addition to the foregoing, the ARB reserves the right in the future to review this Executive Order and
the exemption provided herein to assure that the exempted add—on or modified part continues to meet the
standards and procedures of Title 13, California Code of Regulations, Section 2222, et seq.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF
ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY
ALLEGED BENEFITS OF ALLEN ENGINE DEVELOPMENT‘S SUPERCHARGER KIT.

No claim of any kind, such as "Approved by the Air Resources Board", may be made with respect to the
action taken herein in any advertising or other oral or written communication.

Violation of any of the above conditions shall be grounds for revocation of this order. The order may be
revoked only after a ten—day written notice of intention to revoke the order, in which period the holder of
the order may request in writing a hearing to contest the proposed revocation. If a hearing is requested, it
shall be held within ten days of receipt of the request and the order may not be revoked until a
determination after hearing that grounds for revocation exist.
                                                &       .
Executed at El Monte, California, this   40 7 day of March 1998.




                                       R. B. Summerfield, Chief
                                       Mobile Source Operations Division
