                             EXECUTIVE ORDER D—448—1
                    Relating to Exemptions Under Section 27156
                                of the Vehicle Code


                               WYNJAMMER SUPERCHARCERS
                               WYNJAMMER SUPERCHARCER


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 Wynjammer
Supercharger, manufactured and marketed by Wynjammer Superchargers, 2338 N.
33rd Avenue,   Phoenix,   Arizona 85009,   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 to 1999 5.7 liter GM trucks and sport utility vehicles          (kit #
9685.7).

The Wynjammer Supercharger includes the following main components:
centrifugal supercharger, pulleys, drive belt, assorted brackets, and
hardware.    The diameter of the drive pulley is 7.5 inches,     and the
supercharger pulley diameter is 3.3 inches.        Maximum boost is 6 psi.

This Executive Order is valid provided that the installation instructions for
the Wynjammer 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 Wynjammer
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 Wynjammer Supercharger advertised,
offered for sale,   or sold with or installed on,     a motor vehicle prior to or
concurrent with transfer to an ultimate purchaser.

Marketing of the Wynjammer Supercharger using any identification other than

WYNJAMMER 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 11 (OBD II) system.  Results from
emissions testing conducted at the Edelbrock Corporation Emissions Laboratory
of Torrance, California, are shown below (in grams per mile):

                   Raw              NMOG     Co      NOx        HCHO

The emission test results in the modified configuration were below the
applicable certification standards.  Examination of the OBD II system showed
the Wynjammer Supercharger does not affect OBD II operation.            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 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 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.  PFurther, if such
test results or other evidence provides the ARB with reason to suspect that
the Wynjammer Supercharger will affect the durability of the emission control
system, Wynjammer Superchargers 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 THE WYNJAMMER 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.

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.

                                       SUMMARY




           Wynjammer Superchargers of 2338 N.    33rd Avenue,   Phoenix,   Arizona

85009,   has applied for an exemption from the prohibitions in Section 27156 of

the California Vehicle Code   (VC)   for the Wynjammer Supercharger designed for

1996 to 1999 5.7 liter GM trucks and sport utility vehicles (kit # 9685.7).

           Based on comparison of emissions in the modified configuration with

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

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

the Wynjammer Supercharger will not adversely affect exhaust emissions from

vehicles for which the exemption is requested.

           The staff recommends that Wynjammer Superchargers be granted an

exemption as requested and that Executive Order D—448—1 be issued.

I.     INTRODUCTION

            Wynjammer Superchargers of 2338 N. 33rd Avenue,      Phoenix, Arizona

85009,    has applied   for an exemption from the prohibitions in Section 27156 of

the California Vehicle Code      (VC)   for the Wynjammer Supercharger designed for

1996 to 1999 5.7 liter GM trucks and sport utility vehicles         (kit # 9685.7).

II.    CONCLUSIONS

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

Diagnostic I1    (OBD II)   system with the Wynjammer Supercharger installed, the

staff concludes that the Wynjammer 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 their Wynjammer Supercharger for installation on 1996 to 1999

5.7 liter GM trucks and sport utility vehicles        (kit # 9685.7).

IV.      WYNJAMMER SUPERCHARGER DESCRIPTION

            The Wynjammer Supercharger has been specifically designed for

installation on      1996 to 1999 5.7   liter GM trucks and sport utility vehicles

(kit # 9685.7).       The diameter of the drive pulley is 7.5 inches, and the

supercharger pulley diameter is 3.3       inches.   Maximum boost is    6 psi.

            The intent of   installing the Wynjammer 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

increased because of the compression of intake air by the supercharger.             This

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

engine control module with an increase in fuel flow,        resulting in a higher

power output.

            The installation of the Wynjammer Supercharger requires modification

to the stock accessory belt routing,       crankshaft pulley,   and intake system

components.


v.           DISCUSSION OF THE WYNJAMMER SUPERCHARGER

             Emissions were measured in the modified configuration for comparison

to the applicable certification standards.               It should be noted that the

driving conditions likely to require additional fuel to be provided by the

engine control unit as a result of the boost from the supercharger may not be

present in the CVS—75 FTP.

             A 1999 CM Yukon C1500 with a 5.7L sequential multipoint fuel

injected engine       (XGMXAOS.7185)   was used for the evaluation of the Wynjammer

Supercharger.     The test vehicle was certified to medium—duty vehicle—2 LEV

standards and was equipped with OBD II and an enhanced evaporative system.

The dynamometer inertia weight and horsepower settings were 5,500—lbs and

16—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 Edelbrock

Corporation Emissions Laboratory of Torrance,                California,   are shown below   (in

grams per mile):

                         STD    0.23      6.4          1.0        0.027


             The emission test results in the modified configuration were below

the applicable certification standards.               Examination of the OBD II     system

showed the Wynjammer Supercharger does not affect OBD II operation.

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

                                                —2—


the Wynjammer 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.

         Wynjammer Superchargers has submitted all the required information

and fulfilled the requirements for an exemption.
