                            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 St.,
       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 liter applications:  1994/95 Crown Victoria,
       Grand Marquis, Town Car, 1994—97 Thunderbird/Cougar, and 1996/97 2—valve
       Mustang.

       The 6 PSI. Supercharger Kit includes the following main components:   Eaton
       supercharger with a 2.85" diameter pulley, intake manifold plenum, intake
       manifold runners, intercoocler, 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.
yenm




       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 pollution 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.

       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 confiqguration. 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


ALLEN ENGINE DEVELOPMENT                                EXECUTIVE ORDER D423
6 PSI. SUPERCHARGER KIT                                 (Page 2 of 2)


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.

         I.     INTRODUCTION

                     Allen Engine Development of 255 Lambert Street,     Unit #1,   Oxnard,

         California 93030 has applied for an exemption from the prohibitions in Section

         27156 of the California Vehicle Code (VC)        for their supercharger designed for

         the following Ford 4.6 liter applications:        1994/95 Crown Victoria, Grand

         Marquis, Town Car, 1994—97 Thunderbird/Cougar, and 1996/97 2—valve Mustang.

         II.    —CONCLUSIONS

                     Based on submitted emissions test data,     the staff concludes that

         Allen Engine Development‘s 6 PSI. Supercharger Kit will not adversely affect

         exhaust emissions from the vehicles for which the exemption is requested.

         IIL.    RECOMMENDATION

                     The staff recommends that Allen Engine Development be granted an

         exemption for their 6 PSI. Supercharger Kit for installation on those

         applicable Ford vehicles.      The staff also recommends that Executive Order

         D—423 be issued.

         IV.     SUPERCHARGER KIT DESCRIPTION

                     The 6 PSI.   Supercharger Kit has been specifically designed for

         installation on 4.6 liter,     2—valve Ford vehicles.    The kit operates in

         conjunction with the original equipment manufacturer‘s (OEM) computer

         controlled fuel injection system and emission control system already certified

         with the stock engine.

                     The purpose of supercharging an engine is to increase its volumetric

         efficiency and power output at particular engine loads and throttle openings.

         At light engine loads and small throttle openings, power output is the same as

         a normally aspirated engine.      At heavy engine loads and increased throttle

         openings, the manifold pressure is increased by the supercharger allowing more

         air and fuel to enter the engine, resulting in a higher power output.          The

         supercharger is driven utilizing the engine‘s standard serpentine belt loop

         system.

                     The supercharger used for this kit is an Eaton roots type blower,

         designed to have a maximum boost of 6 psi.         Boost is limited only by the

         diameter of the input pulley which is 2.85".

                                                   =1«—


                 The installation of the kit does not require any major modifications

     to the stock Ford motor, except for the new intake manifold components and the

     relocation of the factory throttle body and EGR port.           A new throttle body

     mounting bracket is supplied with the kit, along with all hardware needed to

     transfer the stock components to the new location.           The stock air cleaner is

     utilized with the supercharger installation.         New parts include the intake

     manifold plenum,    intake manifold runners,     intercooler,   throttle body adapter,

     électric water pump, high flow fuel pump, and a fuel pressure regulator.              The

     EGR valve is relocated between the throttle body and the supercharger.

     v.          DISCUSSION_ OF THE SUPERCHARGER_ KIT

                 A 1996 Ford Mustang with a 4.6L fuel injected engine was used for

     the evaluation of the supercharger.      Testing consisted of one Cold Start

     CVS—75 Federal Test Procedure in the modified confiqguration and an OBD II

     evaluation.     The dynamometer inertia weight and horsepower settings were

     3750—lbs and 8.8—hp, respectively.      The emissions testing was conducted by

     Roush Laboratories for Allen Engine Development, data was evaluated against

     the vehicle‘s emission standards with Dfs applied.           Table 1.   list those

     results.

                                            Table 1.

                                    NMHC       Cco        Nox

                Device w/ Dfs      0.17       2 .39       0 .19

                    Standards      0.25       3 .4        0.4

     The ARB did not perform testing to confirm the emission test results submitted

     by the applicant; however, ARB staff evaluated the impact of the supercharger

     on the OBD II system.      Scan tool testing confirmed that the supercharger did

     not affect the vehicle‘s ability to perform OBD II system operation.

                 Emission test results submitted were below the vehicle‘s applicable

     emission standards with deteriation factors applied.            Therefore, based on the

     test results, the staff concludes that the installation of the supercharger

     will not have an adverse effect on exhaust emissions on those applicable

     vehicles when operated similar to the CVS—75 Federal Test Procedure.             However,
es




     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

                                              —3—


previously prescribed test procedure.   Accordingly, the ARB reserves the right

to conduct additional emission tests,   in the future,   as such tests are

deyeloped, that will more adequately measure emissions from all cycle phases.

         Allen Engine Development has submitted all the required information

and fulfilled the requirements for an exemption.
