State of California AIR RESOURCES BOARD EVALUATION OF KENNE BELL PERFORMANCE PRODUCTS‘ TS1000 TWIN SCREW SUPERCHARGER KIT FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue El Monte, CA 91731—2990 (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.)

SUMMARY Kenne Bell Performance Products, of 10743 Bell Court, Rancho Cucamonga, CA 91730 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for the Kenne Bell TS1000 Twin Screw Supercharger Kit. The supercharger kit is designed for installation on 1986— 1993 model—year Ford Mustangs and 1986 model year Mercury Capris equipped with 5.0 liter engines. Based on the results from emission tests performed by Milton Roy Company of Orange, California, and confirmatory tests at the Haagen—Smit Laboratory on a 1990 Ford Mustang GT, the staff concludes that Kenne Bell TS1000 Twin Screw Supercharger Kit will not adversely affect exhaust emission from vehicles for which an exemption is requested. The staff recommends that Kenne Bell Performance Products be granted an exemption as requested and that Executive Order D—271—1 be issued.

EVALUATION OF KENNE BELL PERFORMANCE PRODUCTS‘ TS1000 TWIN SCREW SUPERCHARGER KIT FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS 1. INTRODUCTION Kenne Bell Performance Products of 10743 Bell Court, Rancho Cucamonga, . California 91730 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code for the Kenne Bell TS1000 Twin Screw Supercharger Kit. The supercharger kit is designed for installation on 1986— 1993 model—year Ford Mustangs and 1986 Mercury Capris equipped with 5.0 liter engines. Kenne Bell Performance Products has submitted data from testing on a 1990 Ford Mustang GT at Milton Roy qampany, Orange, California. In additiofl, the Air Resources Board (ARB) conducted a confirmatory test at the Haagen—Smit Laboratory. II. ConcLuston Based on the results from emission test performed at Milton Roy Company and the confirmatory test by the ARB on a 1990 Ford Mustang GT, the staff concludes that Kenne Bell TS1000 Twin Screw Supercharger Kit will not adversely affect exhaust emissions from vehicles for which an exemption is requested. III. RECOMMENDATIONS The staff recommends that Kenne Bell Performance Products be granted an exemption for their TS1000 Twin Screw Supercharger Kit for installation on

1986—1993 model—year Ford Mustangs and 1986 model year Mercury Capris equipped with 5.0 Liter engine. The staff also recommends that Executive Order D—271—1 be issued. IV. DEVICE DESCRIPTION The Kenne Bell TS1000 Twin Screw Supercharger Kit is designed for installation on 1986—1993 model—year Ford Mustangs and 1986 model year Mercury Capris equipped with 5.0 Liter engines. The supercharger kit is comprised of an Autorotor 3—133 supercharger, a fuel system booster, and other hardware and plumbing necessary to install the kit. The supercharger kit operates in conjunction with the original equipment manufacturer (OEM) computer controlled fuel injection and the emission control system already certified with the stock engine. The purpose of supercharging an engine is to increase its volumetric efficiency and power output at particular engine loads and throttle openings. At light engine loads and small throttle openings, the engine manifold pressure and power output is the same as a normally aspirated engine. At heavy engine loads and increased throttle openings, the manifold pressure is increased by the supercharger allowing more air and fuel to enter the engine, resulting in higher power output. The Autorotor 3—133 supercharger is a positive displacement (1.33L/rev) twin screw rotor air compressor powered by a crankshaft driven serpentine belt. The compressor operates with the rotation of two rotors, a "female" rotor and a

"male" rotor. The "male rotor is driven, using internal gearing, at 1.5 times the speed of the "female" rotor. The maximum volume of air is determined by selecting the proper ratio between the supercharger pulley and the crankshaft pulley. The Kenne Bell TS1000 Supercharger is available with two sizes of supercharger drive pulleys. One kit is offered with a 2.18" diameter pulley which drives the "female" rotor at a speed 2.67 times the speed of the crankshaft pulley. This allows for a maximum boost of 5 p.s.i. The kit is also available with a 2.0" pulley, which drives the "female" rotor at a speed 2.92 times the speed of the crankshaft.; This kit provides an 8 p.s.i. maximum boost. For either kit, the OEM air cleaner assembly and air intake location are used. The OEM mass air flow meter is used, and the fuel delivery and spark timing are controlled by the OEM computer. To maintain the correct air/fuel ratio during boost conditions, additional fuel is supplied by increasing the fuel pressure. This is accomplished by supplying an additional fuel system booster, which is enabled only during boost conditions. This is accomplished by biasing the fuel booster with manifold pressure. Installation of Kenne Bell TS1000 Twin Screw Supercharger Kit does not alter the OEM location of the oxygen sensor or the catalyst. The tune—up specifications also remain the same. v. SUPERCHARCGER KIT SYSTEM EVALUATION AND DISCUSSION A 1990 Ford Mustang GT Convertible equipped with a 5.0 liter (302 CID) fuel injected gasoline engine was used for the evaluation of the TS1000 supercharger kit. The dynamometer inertia weight and loading were 3625—lbs and 9.8—hp respectively.

Emission tests conducted by Milton Roy Company for Kenne Bell Performance Products consisted of one Cold—Start CVS—75 emission test in the baseline configuration and one Cold—Start CVS—75 emission test with the Kenne Bell TS1000 8 p.s.i. supercharger kit installed. Confirmatory tests were performed by the ARB following the same test sequence. A summary of the test results is shown below: Exhaust Emissions Test Results On A 1990 Mustang GT 5.0 (Milton Roy Company) Test Exhaust Emissions (gm/mi) Mode NMHC co NOx Baseline .379 1.317 .751 Modified .085 .485 .676 Difference —77.5% —63.2% —10.0% Confirmatory Test (Haagen—Smit Laboratory) Test Exhaust Emissions (gm/mi) Mode NMHC co Nox Baseline .487 2.529 1.178 Modified .182 * 1.682 .874 Difference —62.6% —33.5% —25.8% Results from the emission tests conducted at Milton Roy Company and the Haagen—Smit Laboratory show the vehicle emissions with the Kenne Bell TS1000 Twin Screw Supercharger Kit installed are not increased when compared to the baseline tests. Based on these test results, the staff concludes that the installation of the Kenne Bell TS1000 Twin Screw Supercharger Kit did not have an adverse effect on exhaust emissions of the affected vehicles. Kenne Bell Performance Products has submitted all the required information and fulfilled the requirements for exemption.
