                                  EXECUTIVE ORDER D—487
                        Relating to Exemptions Under Section 27156
                                    of the Vehicle Code


                                     EXPLORER EXPRESS
                                  X—CHARGER SUPERCHARGER


      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 X—Charger
      supercharger, manufactured and marketed by Explorer Express, 1027 Bell Lane
      Napa, California 94558, 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 1996 through 1999
      model—year 5.0 liter Ford Explorers   (p/n ZD5555).

      The X—Charger supercharger includes the following main components:,     Magnuson
      supercharger, upgraded fuel pump,   longer serpentine drive belt,   spark plug
      wires, assorted brackets, hoses, and hardware.  The diameter of the
      supercharger pulley is 2.60 inches.  Maximum boost attained by this system is
      6 psi.

      This Executive Order is valid provided that the installation instructions for
      the X—Charger 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 X—Charger
      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 X—Charger supercharger using any identification other than
      that. shown in this Executive Order or marketing of the X—Charger 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 X—Charger 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 X—Charger supercharger may have on any warranty either expressed or
      implied by the vehicle manufacturer.

      X—CHARGER SUPERCHARGER                                         (Page 2 of 3)


      This Executive Order is granted based on emissions in the modified
      configuration using the Cold—Start CVS—75 Federal Test Procedure and
      examination of the On—Board Diagnostic II (OBD II) system.  Results from
      emissions testing conducted at the Clean Air Vehicle Technology Center, of
      Hayward, California,        are shown below (in grams per mile):

                            100k              NMOG        CO      NOx          HCHO
                                 DF          0 .045      0 .68   0 .18        0.0008

      The emission test results        in the modified configuration were below the
      applicable certification standards.             Examination of the OBD II system showed
      the X—Charger supercharger does not affect OBD II operation.  Therefore, based
      on the test results, the staff concludes that the Explorer Express X—Charger
      supercharger meets the criteria for exempting general criteria parts.
      However,   the ARB finds that reasonable grounds exist to believe that use of
      the X—Charger supercharger may adversely affect emissions of motor vehicles
      when operating under conditions outside the parameters of the CVS—75 Federal
      Test Procedure.  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 X—Charger 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 Explorer Express X—Charger supercharger will
      affect the durability of the emission control system, Explorer Express 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—onrn 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 THE EXPLORER EXPRESS X—CHARGER SUPERCHARGER.

      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.

                                       SUMMARY


       Explorer Express of 1027 Bell Lane,     Napa,   California 94558,   has applied

for an exemption from the prohibitions in Section 27156 of the California

Vehicle Code   (VC)   for the X—Charger supercharger designed for the 1996 through

1999 model—year 5.0     liter Ford Explorer   (p/n ZD5555) .

           Based on comparison of emissions in the modified configuration with

the applicable standards and an examination of the On—Board Diagnostic IIL         (OBD

II)   system with the supercharger system installed,      the staff concludes that

the X—Charger supercharger will nét adversely affect exhaust emissions from

vehicles for which the exemption is requested.

           The staff recommends that Explorer Express be granted an exemption

as requested and that Executive Order D—487 be issued.

     I.     INTRODUCTION

            Explorer Express of 1027 Bell Lane, Napa, California 94558, has applied

     for an exemption from the prohibitions in Section 27156 of the California

     Vehicle Code (VC)     for the X—Charger supercharger designed for the 1996 through

     II.    CONCLUSIONS

                Based on emission testing,    and examination of the On—Board

     Diagnostic II   (OBD II)   system with the X—Charger supercharger installed,     the

     staff concludes that the Explorer Express X—Chargér supercharger will not

     adversely affect exhaust emissions from the vehicles for which the exemption

     is requested.

     III.    RECOMMENDATION

                The staff recommends that Explorer Express be granted an exemption

     for their X—Charger supercharger for installation on the 1996 through 1999

     model—year 5.0 liter Ford Explorer      (p/n ZD5555).

     IV.    X—CHARGER SUPERCHARGER DESCRIPTION

                The Explorer Express supercharger kit has been specifically desiqgned

     for installation on the 1996     through 1999 model—year 5.0 liter Ford Explorer

     (p/n 2D5555).    The diameter of the supercharger pulley is 2.60 inches.       The

     supercharger is driven by a longer serpentine belt which is connected to the

     stock crankshaft pulley.     Maximum boost attained by this system is   6 psi.       In

     addition to the forced induction provided by the supercharger,      the system

     utilizes an upgraded fuel pump.

                The intent of installing the X—Charger supercharger is to increase

     power output at particular engine loads and throttle openings.      At heavy

     engine loads and increased throttle openings,      the airflow into the engine is
2k

             increased because of the compression of intake air due to the supercharger.

             This allows more air to enter the engine,      which is compensated by an

             adjustment in fuel trim by the vehicle engine control module with an increase

             in fuel flow through the upgraded fuel pump,         resulting in higher power output.

                            The installation of the kit requires modification to the stock

             intake and ignition systems to accommodate components of the X—Charger

             supercharger.     The stock ignition coils are relocated to accommodate the

             supercharger on the engine,      and new spark plug wires are used to connect the

             colills to the spark plugs.     Additional equipment installed during the

             installation include:      Magnuson supercharger,     upgraded fuel pump,    longer

             serpentine drive belt,    spark plug wires,   assorted brackets,    hoses,   and

             hardware.




             V.          pISCUSSION_OF THE X—CHARCGER SUPERCHARCER

                         Emissions were measured in the modified configuration for comparison

             to the apblicable certification standards.       Since the X—Charger supercharger

             kit involves forced induction and an upgraded fuel pump,         a significant

             increase in emissions could have resulted.       However,    since Explorer Express

             opted to test against the applicable emission standards,         it was not possible

             to quantify any emissions increases due to the X—Charger supercharger.

                         A 1999 médel—year 5.0 liter Ford Explorer with a 5.0L sequential

             multipoint fuel injected engine      (XFMXT5.02GF)   was used for the evaluation of

             the X—Charger supercharger.       The test vehicle was certified to light—duty

             truck—2 LEV standards and was equipped with OBD II and an enhanced evaporative

             system.     The dynamometer inertia weight and horsepower settings were 4,750—1lbs

             and 12.6—hp,    respectively.    Testing consisted of two CVS—75 FTP‘s in the

             modified configuration to set all readiness codes,         emissions were measured

             during one CVS—75 FTP.    The ARB did not perform testing to confirm the test

             results submitted by the applicant.


                 Results from emissions testing conducted at the Clean Air

Vehicle Technology Center,       of Hayward,       California,     are shown below   (in grams

per mile):

             The emission test results in the modified configuration were below

the applicable certification standards.               Examination of the OBD II system

showed the X—Charger supercharger does not affect OBD II operation.

Therefore,    based on the test results,          the staff concludes that the X—Charger

supercharger meets the criteria for exempting general criteria parts.

However,   the ARB finds that reasonable grounds exist to believe that use of

the xX—Charger supercharger may adversely affect emissions of motor vehicles

when operating under conditions outside the parameters of the previously

prescribed test procedure.           Accordingly,    the ARB reserves the right to conduct

additional emission tests in the future,             as such tests are developed.

             Explorer Express has submitted all the required information and

fulfilled the requirements for an exemption.
