EVALUATION OF KENNE BELL, INC. ADD—ON TURBOCHARGER KIT, MODEL NO. KB7700 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, Inc. (Kenne Bell) of 10743 Bell Court, Rancho Cucamonga, CA 91730, has applied for an exemption from the prohibitions of Vehicle Code Section 27156 for their add—on Turbocharger Kit, Model No. KB7700. The turbocharger kit is intended for installation on 1991 & 1992 model—year Nissan 2408X powered by a 2.4 liter gasoline engine equipped with multiport fuel injection. II. CONCLUSIONS Kenne Bell has submitted data from tests conducted on a 1991 Nissan 2408X powered by a 2.4 liter engine. Based on these results, the staff concludes that Kenne Bell‘s add—on turboéharger kit will not adversely afféct exhaust emissions on those vehicles for which an exemption is requested. & III. RECOMMENDATION The staff recommends that Kenne Bell be granted an exemption for their add—on Turbocharger Kit, Model No. KB7700, for installation on 1991 & 1992 model—year Nissan 2408X powered by a 2.4 liter gasoline engine, and that Executive Order D—271 be issued. IV. TURBOCHARGER KIT DESCRIPTION The Kenne Bell Turbocharger Kit, Model No. KB7700 is specifically designed for installation on 1991 & 1992 model—year Nissan 240SX sports cars powered by a 2.4 liter gasoline engine. The kit operates in conjunction ~1—

with the emission control system already certified with the stock engine. The purpose of turbécharging 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—turbocharged condition. This is accomplished through the combination of an intercooler and a Garrett—T25 turbocharger with an A/R ratio of 0.86. Maximum positive manifold pressure or boost is limited to 8 psi due to wastegate design. To provide additional fuel to maintain the proper air/fuel ratio during boost conditions, modifications are made to the programmable read only memory (PROM) computer chip and the fuel injectors. Calibration data in the PROM has been modified to compensate fgr the addition of the turbocharger. These changes include wide—open—throttle adjustments to the spark table and fuel map. The stock fuel injectors (268cc rating) are replaced with larger injectors (386cc rating) to provide the correct air to fuel ratio at wide— opefi—throttle (WOT}. Support accessories on the turbocharger kit include a replacement of the following: relocating and replacing the stock air filter with a Kenne Bell open element (KB8024) air filter, replacing the stock muffler and tailpipe with a Kenne Bell muffler and tailpipe, and replacing stock exhaust manifold with a stainless steel manifold to accommodate the turbocharger. v. DISCUSSION OF THE TURBOCHARCER KIT A 1991 Nissan 2405X powered by a 2.4 liter engine with multipoint fuel injection was used for the evaluation of the turbocharger kit. The dynamometer inertia weight and loading used during the testing were 3,125 lbs. and 8.2 hp.

Emission tests conducted by Milton Roy Company consisted of one Cold— Start CVS—75 Federal Test>Procedure with the Turbocharger Kit, Model No. KB7700 installed. This test was used to compare vehicle exhaust emissions in the modified configuration with the applicable emission standards. Test results are shown below: ® Exhaust Emissions Test Results from Milton Roy Company 1991 Nissan 2408X Exhaust Emissions m/mi Test Mode BC co NOx Device 0.21 2.8 0.14 Standard 0.39 7.0 0.4 Difference —0.18 —4.2 ~0.26 Test results submitted by Kenne Bell show that Carbon Monoxide (CO}, Oxides of Nitrogen (NOx), and Hydrocarbons (HC) exhaust emissions of the vehicle in the modified configuration are below the applicable emission standards for the Nissan 240SX. The test has shown the Kenne Bell Turbocharger Kit, Model Number KB7790, not to reduce the effectiveness of the emissions control systems of the Yehicle. Kenne Bell has fulfilled the requirements for the exemption and, therefore, Executive Order D—271 should be issued.
