SUMMARY Paxton Products, Inc. (Paxton) of 929 Olympic Bivd., Santa Monica, California 90404, has applied for an exemption from the prohibitions of Vehicle Code Section 27156 for their add—on supercharger kit model number SN—89, part number 2608789. The supercharger kit is intended for installation on 1986—1991 model—year General Motors vehicles powered by a 305 CID (5.0L) or 350 CID (5.7L) engines with either Tuned Port Fuel Injection or Throttle Body Fuel Injection. Paxton has submitted data from tests conducted on a 1991 Chevrolet Caprice Classic powered by a 305 CID engine at Milton Roy Company. Based on these results, the staff concludes that Paxton‘s add—on supercharger kit will not adversely affect exhaust emissions from vehicles for which an exemption is requested. The staff recommends that Paxton be granted an exemption for their add— on supercharger kit model number SN—89, part number 2608789, for installation on 1986—1991 model—year General Motors vehicles powered by a 305 CID (5.0L) or 350 CID (5.7L) engines, and that Executive Order D—195—6 be issued.

EVALUATION OF PAXTON PRODUCTS, INC.‘S ADD—ON SUPERCHARGER KIT MODEL NO. SN—89, PART NO. 2608789 FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION Paxton Products, Inc. (Paxton), of 929 Olympic Blvd., Santa Monica, California 90404, has applied for an exemption from the prohibitions of Vehicle Code Section 27156 for their add—on supercharger kit model number SN—89, part number 2608789. The supercharger kit is intended for installation on 1986—1991 General Motors vehicles powered by a 305 CID (5.0L) or 350 CID (5.7L) engines with either Tuned Port Fuel Injection or Throttle Body Fuel Injection. II. CONCLUSIONS Paxton has submitted data from tests conducted on a 1991 Chevrolet Caprice Classic powered by a 305 CID Throttle Body Injected engine at Miiton Roy Company. Based on these results, the staff concludes that Paxton‘s add— on supercharger kit will not adversely affect exhaust emissions from the vehicles for which an exemption is requested. III. RECOMMENDATION The staff recommends that Paxton be granted an exemption ffir their add— on supercharger kit model number SN—89, part number 2608789, for installation on 1986—1991 model—year General Motors vehicles powered by a 305 CID (5.0L) or 350 CID (5.7L) engines with either Tuned Port Fuel Injection or Throttle Body Fuel Injection, and that Executive Order D—195—6 be issued. IV. SUPERCHARGER KIT DESCRIPTION The Paxton supercharger kit is specifically designed for installation —1—

on 1986—1991 General Motor vehicles powered by 305 CID (5.0L) or 350 CID (5.7L) engines. The kit operates in conjunction with the original equipment manufacturer (OEM) computer controlled fuel injection systems and emission control systems already certified with the stock engine. The purpose of supercharging an engine is to increase the volumetric efficiency of an 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, Paxton Model No. SN—89, that is belt driven at 1.5 times the speed of the engine. Intake air is delivered from the OEM air filtering system to the centrifugal blower. It is then compressed by the supercharger and routed to the throttle body of the electronic fuel injection system. Maximum positive manifold pressure or boost ié limited to 5 psig by the blower scroll housing and the impeller design. No wastegate or other active boost limiting device is used. To provide additional fuel to maintain the proper air/fuel ratio during boost conditions a fuel control unit is added. The fuel control unit when placed in series with the OEM fuel pressure regulator in the fuel return line will increase the fuel pressure and fuel delivery, under boost conditions. The unit is activated by a solenoid valve that is turned "on" and "off" via a pressure switch which is set at 0.95 psi. This pressure setting is based on the inlet manifold pressure. The fuel control unit has a set static pressure of 70 psi. Maximum static pressure of the OEM fuel pressure regulator is about 34 psi. The blower is self lubricated by a piston—type oi1 pump. The oil sump has a capacity of 12 fluid ounces and uses type "F" automatic transmission fluid. All OEM emission controls are left intact.

V. SCUS 0 $ HARGER: K A 1991 Chevrolet Caprice Classic powered by a 305 CID engine with Throttle Body Fuel Injection was used for the evaluation of the supercharger kit. The dynamometer inertia weight and loading used during the testing were 4,250 lbs. and 8.1 hp, respectively. Emission tests conducted by Milton Roy Company consisted of cold—start CVS—75 emission tests with the supercharger installed on the test vehicle. This test was used to compare vehicle exhaust emissions in the modified configuration with the applicable emission standards. The test results are shown below: Table 1 Exhaust Emissions Test Results from Milton Roy Company Exhaust Emissions ({gm/mi) lest Mode HC 0_ NOx Device .0 .287 3.338 0.275 Device 0.375 5.483 0.222 Standard 0.39 7.0 0.4 ‘Test results submitted by Paxton show that Carbon Monoxide (CO), Oxides of Nitrogen (NOx), and Hydrocarbons (HC), exhaust emissions of the vehicle in the modified configuration is below the applicable emission standards. The test has shown the Paxton supercharger model number SN—8%, part number 2608789, not to reduce the effectiveness of the emissions control systems of the vehicle. Paxton has fulfilled the requirements for the exemption and, therefore, Executive Order D—195—6 should be issued.
