                                  EXECUTIVE ORDER D—429
                    Relating to Exemptions Under Section 27156
                                of the Vehicle Code

                                     CAMERON CONCEPTS
                                 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 Cameron Concepts, 7515 Dagget St., San
Diego, California 92111 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 1985—97 Rover Group
Limited vehicles equipped with the 4.0/4.6L engine.

The 6 PSI. Supercharger Kit includes the following main components:       Eaton
supercharger,    hardware and tubing necessary to connect to stock intake
manifold and air filter housing, and a throttle—body adaptor plate.  No
changes are made to the stock fuel delivery system or ignition system.  The
manufacturer recommends 91 or higher octane fuel.  The 4.6L kit includes a
2.93" diameter supercharger pulley and the 4.0L kit includes a 3.2765"
diameter pulley.

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 which
showed that the Cameron Congepts‘ 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 Cameron Concepts‘    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, Cameron Concepts 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.

                           CALIFORNIA CODE OF REGULATIONS


I.     INTRODUCTION

            Cameron Concepts of 7515 Dagget Street,   San Diego,   California 92111

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

California Vehicle Code (VC) for their supercharger designed for 1985—97 Rover

Group Limited vehicles equipped with the 4.0/4.6L engine.

II.    CONCLUSTONS

            Based on submitted emissions test data, the staff concludes that

Cameron Concepts‘     6 PSI. Supercharger Kit will not adversely affect exhaust

emissions from the vehicles for which the exemption is requested.

III.    RECOMMENDATION

            The staff recommends that Cameron Concepts be granted an exemption

for their 6 PSI. Supercharger Kit for installation on those applicable Rover

vehicles.    The staff also recommends that Executive Order D—429 be issued.

IV.     SUPERCHARGER KIT DESCRIPTION

            The 6 PSI.   Supercharger Kit has been specifically designed for

installation on      1985—97 Rover Group Limited vehicles equipped with the

4.0/4.6L engine.      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,

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

diameter of the input pulley.

            The installation of the kit does not require any major modifications

to the stock motor, except for the new intake tubing and the relocation of the

factory throttle body.       A new throttle body mounting bracket is supplied with

                                          —1«—


         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 air tubing which connects the

         supercharger to the stock intake manifold and‘stock air cleaner, throttle body

         adapter,    and all necessary hardware to mount the supercharger kit.

         v.          DISCUSSION OF THE SUPERCHARGER KIT

                     A 1996 Range Rover with a 4.0L 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 5500—lbs and

         13.9—hp, respectively.         The emissions testing was conducted by Roush

         Laboratories for Cameron Concepts,          data was evaluated against the vehicle‘s

         emission standards.         Table 1.   list those results.

                                                     Table 1.

                                            NMHC        CO         Nox

                    Device w/ Dfs          0 .24       2 .65        0.36

                        Standardas         0 .32       4 .4         0 .7

         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 the OBD II system operation.

                     Emission test results submitted were below the vehicle‘s applicable

         emission standards with deterioration factors applied.              Therefore,   based on

         the test results and OBD II evaluation,              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.

                     Rover Group Limited certified one engine family in 1997

         (VLR4.058GFFK) to the Enhanced Evaporative Emission Standards.                The vehicle‘s

         evaporative emissions should not be affected because the installation of

         Cameron Concepts‘ Supercharger Kit does not modify the vehicle‘s fuel or

         evaporative emission control system, and the stock closed element air cleaner
—stom.




         is retained.     Cameron Concepts has submitted all the required information and

         fulfilled the requirements for an exemption.
