                              EXECUTIVE ORDER D—448
                    Relating to Exemptions Under Section 27156
                               of the Vehicle Code


                             WYNJAMMER SUPERCHARGERS
                               SUPERCHARGER SYSTEM


Pursuant to the authority vested in the Air Resources Board by Section 27156
of the Vvehicle 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 Wynjammer
supercharger system, manufactured and marketed by Wynjammer Superchargers,
Wynjammer Superchargers, 8321 E. Evans Road #101, Scottsdale, Arizona 85260
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 5.4L applications:
1997 model—year Expedition, Navigator, F—150, and F—250 (kit # 975.4).

The Wynjammer supercharger system includes the following main    components:
Wynjammer supercharger, replacement open—element air cleaner,    and assorted
brackets, tubing, hoses, fittings and hardware.  The diameter    of the drive
pulley is 6.5 inches, and the supercharger pulley diameter is    2.6 inches.

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 system,
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 emissions testing and examination of
the On—Board Diagnostic II (OBD—II) system of the vehicle in the modified
configuration.   Results from emissions testing yielded emissions within the
applicable standards with the original manufacturer‘s (Ford‘s) deterioration
factors applied.   The emissions results are shown below:

 Therefore,    based on the test results,         the staff concludes that the Wynjammer
 supercharger meets the criteria for exempting general criteria parts as
 specified in the "Procedures for Exemption of Add—On and Modified Parts".
 However, the ARB finds that reasonable grounds exist to believe that use of
 the Wynjammer supercharger may adversely affect emissions of motor vehicle®©
 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 Wynjammer supercharger system adversely affects emissl0Ons
 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 system,         Wynjammer shall be required to submit durability dgta
. to show that the durability of the vehicle emission control system is not,                           AD
 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 ©°4—

 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 WINJAMMER SUPERCHARGERS® SUPERCHARGER KIT.

 No claim of any kind,          such as "Approved by the Air Resources Board",                may P®
 made with respect to the action taken herein in any advertising or other oal
 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


             Wynjammer Superchargers of 8321 E. Evans Road #101, Scottsdale,

?rizona     85260 has applied for an exemption from the prohibitions in Section

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

for the following Ford 5.4L applications:             1997 model—year Expedition,

Navigator,    F—150,   and FP~250   (kit # 975.4).


II.     CONCLUSIONS


             Based on testing in the modified configuration,          the staff concludes


that Wynjammer Superchargers‘        supercharger will not adversely affect exhaust


emissions from the vehicles for which the exemption is requested.

III.    RECOMMENDATION


            The staff recommends that Wynjammer Superchargers be granted an

exemption for the Wynjammer supercharger system (kit # 975.4) for installation

on those applicable 1997 model—year Ford vehicles.              The staff also recommends

that Executive Order D—448 be issued.


IV.    SUPERCHARGER DESCRIPTION


            The Wynjammer supercharger has been specifically designed for

installation on the following 1997 model—year Ford vehicles equipped with 5.4L

engines:      Expedition,   Navigator,   F—150,   and F—250    (kit # 975.4).


The system operates in conjunction with the original equipment manufacturer‘s


(OEBM) 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

                                             —1—


through an increase intake air pressure.      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 by the crankshaft by means of a belt.      The

diameter of the drive pulley is 6.5 inches, and the supercharger pulley

diameter is 2.9 inches.

          The supercharger used for this kit is a Wynjammer belt driven

centrifugal unit, designed to produce boost over a wide range of exhaust

flowrates by maintaining high compressor speeds.     Maximum boost pressures

attained are 4 to 6.5 psi.

          The installation of the supercharger kit does not require any major

modifications to the stock Ford motor,    except for the modification of the


factory intake system,    and crankshaft pulley to accommodate the supercharger


drive pulley.

v.        DISCUSSION OF THE   SUPERCHARGER


          A 1997 model—year Ford Expedition (Tier—1, MDV3, engine family

VFMS.4GIFK) with a 5.4L engine was used for the evaluation of the

supercharger.   The dynamometer inertia weight and roadload horsepower settings

were 6,500—lbs and 16.2—hp,   respectively.   Testing consisted of two CVS—75


FTP‘s in the modified configuration to verify proper operation of the OBD—II

system.   The emissions of the test vehicle were measured once in the modified

configuration.‘ The ARB did not perform testing to confirm the test results


submitted by the applicant.

          Results from emissions testing conducted at the Edelbrock

Corporation Emissions Laboratory yielded emissions within the applicable

standards with the original manufacturer‘s (Ford‘s) deterioration factors


applied.    The emissions results are shown below:

              Raw            NMEC    co       NOx
           Emission Level    0.123   1.009    0.188

              50k            NMHC    co       NOx
                      DF     0.016   0.316    0.100
           Emission Level    0.139   1.3      0.3
           {w. DF applied)
                     STD     0.39             1.1

              100%k          NMHC    co       NOx
                       DF    0.040   0 .797   0.252
           Emission Level    0.163   1.8      0 .44
           (w. DF applied)
                      STD    0.56



Therefore, based on the test results, the staff concludes that the Wynjammer

supercharger meets the criteria for exempting general criteria parts as


specified in the "Procedures for Exemption of Add—On and Modified Parts".

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


the Wynjammer supercharger may adversely affect emissions of motor vehicles


when operating under conditions outside the parameters of the previously


prescribed test procedure.

           Wynjammer Superchargers has submitted all the required information

and fulfilled the requirements for an exemption.
