EVALUATION OF TOYOTA RACING DEVELOPMENT‘S SUPERCHARGER KIT FOR AN EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION Toyota Racing Development of 335 E. Baker Street, Costa Mesa, California 92626 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for their supercharger designed for 1995—98 T100, 1995—98 Tacoma, and 1996—98 4—Runner that are equipped With a 3.4L engine. II. CONCLUSIONS Based on submitted emissions test data, the staff concludes that Toyota Racing Development‘s 6 PSI. Supercharger Kit will not adversely affect exhaust‘emissions from the vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that Toyota Racing Development be granted an exemption for their 6 PSI. Supercharger Kit for installation on those applicable Toyota vehicies. The staff also recommends that Le~ Executive Order D—425—2 be issued. IV. SUPERCHARGER KIT DESCRIPTION The 6 PSI. Supercharger Kit has been specifically designed for installation on 1995—98 T100, 1995—98 Tacoma, and 1996—98 4—Runner that are equipped with a 3.4L engine. The kit operates in conjunction with the original equipment manufacturer‘s (OEM) computer controlled fuel injection system and 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, 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 to enter the engine, resulting in a hig'her power output. The supercharger is driven utilizing the engine‘s standard serpentine belt loop system.

The supercharger used for this kit is an Eaton roots type blower, designed to have a maximum boost of 6 PSI. Boost is limited only by the diameter of the input pulley. The installation of the kit does not require any major modifications to the stock motor, except for the new intake manifold and fuel regulator. The stock air cleaner is utilized with the supercharger installation. v. DISCUSSION OF THE SUPERCHARGER KIT | A 1998 Toyota T100 with a 3.4L fuel injected engine certified to a TLEV emission standard was used for the evaluation of the supercharger. Testing consisted of one Cold Start CVS—75 Federal Test Procedure in the modified configuration, and an OBD II evaluation. Thé dynamometer inertia weight and horsepower settings were 4500—lbs and 16.6—hp, respectively. The emissions testing was conducted by the Edelbrock Corporation. NMOG and HCHO were calculated following NMOG/NMHC ratio of 1.032 and HCHO/NMHC ratio of 0.018 as submitted by Toyota during its new vehicle certification. Table 1. list emission results in gm/mi. with the deterioration factors applied. mm Table 1. NMOG CO _ NOx HCHO Device 0.16 1.8 0.2 0.003 Standard 0.16 4.4 0.7 0.018 Results from the emissions test conducted at Edelbrock show the vehicle emissions with the 6 PSI. Supercharger installed to be within the vehicle‘s emission standards. Based on the test results, the staff conclgdes that the installation of the Toyota Racing Development‘s 6 PSI. Supercharger Kit will not have an adverse effect on exhaust emissions of the affected vehicles. The ARB did not perform testing to confirm the emission test results submified by the applicant; however, ARB staff evaluated the impact of the supercharger on the OBD II system. Scan tool testing confirmed that the supercharger did not affect the vehicle‘s ability to perform the OBD II system operation. Therefore, based on the test results and — 2 —

OBD II evaluation, the staff concludes that the installation of the supercharger will not have an adverse effect on exhaust emissions on those applicable vehicles when operated similar to the CVS—75 Federal Test Procedure. Toyota Racing Development has submitted all the required information and fulfilled the requirements for an exemption.
