State of California AIR RESOURCES BOARD EVALUATION OF K. F. INDUSTRIES, INC.‘s MAX—25 SUPERCHARGER KIT FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE September, 1987

Date of Issue: September, 1987 EVALUATION OF K. F. INDUSTRIES, INC.‘s MAX—25 SUPERCHARGER KIT FOR EXEMPTION FROM THE PROKIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE by Mobile Source Division State of California AIR RESOURCES BOARD 9528 Telstar Avenue El Monte, CA 91731 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.)

summany K. F. Industries, Inc. (KFI) has applied for exemption from the prohibitions in Vehicle Code Section 27156 for their MAX—25 supercharger kit designed for 1986—1988 model—year Chevrolet and GMC light—duty trucks powered by a 2.8 liter V—6 gasoline fuel—injected engine. ‘ Based on the results from comparative exhaust emissions tests performed by K. F. Industries, at an independent laboratory, on a 1987 GMC S$15 4x4 pick—up truck and from confirmatory tests performed at the Haagen—Smit Laboratory, the staff concludes that the K. F. Industries, Inc. MAX—25 supercharger kit will not adversely affect emissions from the vehicles described above. The staff recommends that K. F. Industries, Inc. be granted an exemption as requested and that Executive Order D—150—2 be issued.

EVALUATION OF K. F. INDUSTRIES, INC.‘S MAX—25 SUPERCHARGER KIT FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE 1. INTROBUCTION K, F, Industries, Inc., (KFI) of Sun Valley, California 91353, has requested an exemption from the prohibitions in Vehicle Code Section 27156 for their MAX—25 supercharger kit. The supercharger kit is designed for installation on 1986—1988 model—year Chevrolet and GMC light—duty trucks powered by a 2,.8 liter V—6 gasoline fuel—injected engine. KFI has submitted data from comparative (stock baseline vs. supercharged) emissions tests conducted on a 1987 GMC S—15 4x4 pick—up truck at Import Certification Laboratories, Inc., Orange, California,. Confirmatory tests were conducted on the same vehicle at the Haagen—Smit Laboratory in El Monte, California. IL. CONCLUSION Based on the results from comparative exhaust emissions tests performed by KFI, at an independent laboratory on a 1987 GMC S—15 4x4 pick—up truck, and from confirmatory tests performed by the ARB on the same vehicle, the staff concludes that KFI‘s supercharger kit will not adversely affect exhaust emissions from the vehicles described above. III. RECOMMENDATIONS The staff recommends that KFI be granted an exemption for their add—on MAX—25 supercharger kit and that Executive Order D—150—2 be issued, IV., SUPERCHARGER KIT DESCRiPTION The MAX—25 Supercharger Kit has been specifically designed for installation on the 1986—1988 GMC 2.8 liter, V—6 gasoline fuel—injected engine. The kit operates in conjunction with the OEM throttle body

fuel—injection and the emission control systems already certified with the stock engine. All the necessary hardware and supplies are included‘"in the kit. Some of the OEM parts are removed and discarded to be replaced by custom parts supplied with the kit. A complete manual describing the parts, and step—by—step installation procedures is supplied with the kit {see Appendix 1). The supercharger (Model No. 510—9517408—1) is belt driven at 2.0 times the speed of the engine which provides 5 psig of boost at 5000 rpm. To provide additional fuel to maintain proper air—fuel ratios during boost conditions, larger fuel injectors are installed in the OEM throttle body. A spring loaded door is added to the air cleaner assembly to allow for additional air flow during boost conditions. The Electronic Control Module (ECM) PROM is replaced with a KFI PROM which calibrates the ECM to perform in conjunction with the supercharger. All functions of the ECM are maintained, however, they are slightly modified by the KFI PROM. Cold—start, EGR control, fuel control, and spark control are modified to maintain acceptable emissions from the supercharged vehicle. The KFI PROMs are identified by the OEM GM part numbers they replace and the designation "KF—18" (see Appendix 2). A noticeable power improvement is achieved and driveability remains good. Fuel economy is slightly reduced but emissions remain at or below baseline levels. In addition to the standard kit identification label required by the ARB for exempted aftermarket parts, KFI will supply an additional sticker to be attached to the ECM stating that the PROM has been changed so that if there is a PROM failure the KFI PROM must be installed instead of the OEM PROM which may cause engine damage if used in conjunction with the supercharger (see Appendix 3).

V. SUPERCHARGER KIT EVALUATION A 1987 GMC S—15 4x4, light—duty pick—up truck with a 2.8 liter, V—6 gasoline fuel—injected engine was used for the evaluation of the supercharger kit. The dynamometer inertia weight and loading used were 4000 Ilbs. and 11.8 hp, respectively. Comparative emissions tests conducted by Import Certification Laboratories, Inc. for KFI and by the ARB, consisted of back—to—back cold—start CVS—75 emissions tests and hot—start Highway Fuel Economy tests. These tests were used to determine exhaust emissions in the unmodified (baseline) and supercharged (device installed) configurations for comparison. A summary of the test results is shown below: Exhaust Emissions Test Results On A 1987 GMC S—15 4x4 Pick—Up Truck A.

VI. DISCUSSION The results of the exhaust emissions tests performed on the test vehicle show no signifiant increase in emissions due to the installation of the supercharger kit. KFI has fulfilled the requirements for the exemption and therefore Executive Order D—150—2 should be issued.
