                                    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.

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.

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.
