State of California AIR RESOURCES BOARD 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.

SUPERCHARGER KIT (Page 2 of 2) 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 982. 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 ALLECGED BENEFITS OF CAMERON CONCEPTS‘ 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.

FOR AN EXEMPTION FROM THE PROHfEiTIONS OF VEHICLE COD SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE 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. —2—
