SUMMARY Weiand Automotive Industries, Inc. (Weiand) of 2316 San Fernando Road, Los Angeles, California 90065, has applied for an exemption from the prohibitions in Vehicle Code Sections 27156 and 38391 for their add—on supercharger kit model 6510. The supercharger kit is intended for installation on 1962—1986 model—year carbureted "small block" Chevrolet vehicles powered by 283, 302, 305, 307, 327, and 400 CID gasoline engines. Weiand has submitted data from emissions test conducted on a 1986 Chevrolet light—duty pick—up truck powered by a 302 CID (5.0L) gasoline engine at Milton Roy Company (Milton Roy), an independent laboratory in Orange, California. Confirmatory tests were conducted on the same vehicle at the Air Resources Board‘s (ARB‘s) Haagen—Smit Laboratory. Based on the results from the comparative emission tests performed by Milton Roy and by the ARB, the staff concludes that Weiand‘s add—on supercharger kit will not adversely affect exhaust emissions from vehicles for which exemption is requested. The staff recommends that Weiand be granted an exemption as requested for their add—on supercharger kit model 6510, and that Executive Order No. D—256—1 be issued.

EVALUATION OF WEIAND AUTOMOTIVE INDUSTRIES, INC. "PRO—STREET" SUPERCHARGER KIT MODEL 6510 FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 AND TITLE 13, SECTION 2222, CALIFORNIA CODE OF REGULATIONS 1. INTRODUCTION Weiand Automotive Industries, Inc. (Weiand) of 2316 San Fernando Road, Los Angeles, California 90065, has applied for an exemption from the prohibitions in Vehicle Code Sections 27156 and 38391 for their supercharger kit model 6510. The supercharger kit is intended for installation on 1962— 1986 model—year carbureted "small block" Chevrolet vehicles powered by 283, 302, 305, 307, 327, 350, and 400 CID gasoline engines. Weiand has submitted data from comparative emissions tests conducted at Milton Roy, an independent test laboratory in Orange, California. Confirmatory tests were conducted on the same vehicle at the ARB‘s Haagen— Smit Laboratory in El Monte, California. II. CONCLUSTON Based on the results from tests conducted at Milton Roy on a 1986 carbureted Chevrolet light—duty pick—up truck powered by a 302 CID (5.0L) gasoline engine, and the ARB‘s confirmatory tests on the same vehicle, the staff concludes that Weiand‘s add—on supercharger kit will not adversely affect exhaust emissions from vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that the exemption be granted as requested and that Executive Order No. D—256—1 be issued, permitting the advertisement, sale and installation of the Weiand‘s supercharger on 1962—1986 model—year carbureted "small block" Chevrolet vehicles powered by 283, 302, 305, 307, 327, 350, and 400 CID gasoline engines.

IV. DEVICE DESCRIPTION The Weiand supercharger kit is specifically designed for installation on 1962—1986 Chevrolet vehicles indicated above. The purpose of supercharging an engine is to increase the volumetric efficiency of the engine by forcing more air into the engine than it would consume in normal aspirated, non—supercharged condition. This is accomplished by the addition ‘of a centrifugal blower. The inducted air and fuel drawn from the carburetor are then compressed by the supercharger and mechanically pumped into the intake manifold. The carburetor throttle blades must be in the open position for the supercharger to have a full charge to compress and reach the boost pressure. The supercharger kit includes an intake manifold which provides for connection of all pollution control devices required on the vehicle. All other original equipment manufacturer (OEM) emission controls are left intact. Weiand supercharger is designed to produce maximum boost pressure of 4—6 psi when installed on stock 350 CID engine. The applicant claims a power gain of 30—40 percent by the use of the supercharger on an engine in a good operating condition. The supercharger is packaged with installation instructions, hardware, and technical manual. v. DEVICE _EVALUATION The applicant has submitted test results conducted at Milton Rdy, an independent test laboratory, in Orange, California. One CVS—75 test was conducted on a 1986 Chevrolet light—duty pick—up truck poweréd by a 5.0L gasoline engine in the unmodified (baseline) configuration, and one CVS test was conducted following the installation of the supercharger by Weiand at their facility. The same test procedures were repeated during the confirmatory tests by the ARB following the successful completion of testing at Milton Roy. The test results are shown bellow.

CVs—75 Test Results {Milton Roy Company Laboratory) THC co NOx Baseline (gm/mi) 0.551 11.709 0.683 Supercharger kit (gm/mi) 0.510 12. 388 0.325 Percent change —7.4 +5.8 —52.4 CVS—75 Test Results (Air Resources Board) THC co NOx Baseline {gm/mi}) 1.027 21.748 1.231 Supercharger kit (gm/mi) 0.991 18. 360 1.232 Percent change —3.5 —15.6 +0.1 The test results from Milton Roy and the ARB showed no significant emissions increase from the test vehicle due to the installation of the Weiand‘s "Pro— Street" supercharger kit model 6510. Based on the test results, the staff concludes that the Weiand‘s supercharger kit model 6510 will not produce adverse effect on applicable vehicles.
