The WhippleCharger is a supercharger consisting of the following main components: Twin Screw Whipple supercharger, two auxiliary fuel injectors with a stand alone computer, air bypass valve, a low temperature thermostat to replace stock thermostat, and a new closed element air cleaner housing. An intercooler is included on selected kits anddenoted as IC in the part number. The maximum boost is 10 psi. 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. Whipple Industries, Inc. recommends that only premium fuel be used. Changes made to the design or operating conditions of the WhippleCharger, 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 Whipple Industries, Inc.‘s WhippleCharger advertised, offered for sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer to an ultimate purchaser. 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 seill, offer for sale, or advertise any component of the kit as an individual device.

7. 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 generated on a 2004 model year General Motors C1500 certified to the Super Ultra Low Emission Vehicle (SULEV) emission standards. Testing consisted of a Cold—Start CVS—75 Federal Test Procedure (FTP) and the Supplemental Federal Test Procedure (SFTP USO6/SCO3) test cycle. Results are in grams per mile with deterioration factors added to CVS—75 FTP results. Emission levels of the modified vehicle met the applicable emission standards. .

Test data showed that the supercharger when installed on the vehicle did not affect the vehicle‘s ability to perform its OBD II monitoring. 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.
