SUMMARY % The Turbo Shop, Inc. ({Turbo Shop) has applied for an update to Executive Order D—97—20 which exempts the Turbocharger Kit number 60— 0002/4 HD from the prohibitions of Vehicle Code Section 27156. The existing exemption applies to 1983 model year General Motors Corporation (GMC) heavy— duty vehicles (GVW over 8500 lbs.) powered by a 6.2L GMC heavy—duty diesel engine. The update is requested to reflect a change of ownership from BAE Turbosystems to the Turbo Shop, Inc. and to include 1984 through 1990 mode! year GMC vehicles powered by a 6.2L heavy—duty diesel engine. Because the Turbocharger Kit number 60—0002/4 HD which was granted an exemption for the 1983 model year 6.2L GMC heavy—duty vehicles remain unchanged and the 6.2L heavy—duty engines used on the 1984 through 1990 model year GMC vehicles are carried—over from the 1983 model year, the staff concludes that the turbocharger kit will not have an adverse effect on exhaust emissions from vehicles for which the exemption update has been requested. The staff recommends The Turbo Shop, Inc. be granted an update as requested and that Executive Order D—180—6 be issued.

EVALUATION OF THE TURBO SHOP, INC.‘S ADD—ON TURBOCHARGER KIT FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE. I. INTRODUCTION BAE Turbosystems of 3032 Kashiwa Street, Torrance, CA 90505 has received an exemption from the prohibitions of Section 27156 of the Vehicle Code under Executive Order D—97—20 for its Turbocharger Kit model 60—0002/4 HD. Under this exemption, the device can be used on 1983 model year 6.2L GMC heavy—duty diesel engines. The Turbo Shop, Inc. (Turbo Shop) of 940 West Manchester, Inglewood, CA 90301, acquired the rights to Turbocharger Kit model 60—0002/4 HD. Turbo Shop has requested an update to Executive Order D—97—20, to include 1983 through 1990 GMC heavy—duty vehicles powered by a 6.2L GMC heavy—duty diesel engine and to reflect a change in ownership. Turbo Shop claims no change in the design of the original unit. II. CONCLUSION Turbo Shop‘s turbocharger kit was previously granted an exemption for the 1983 model year 6.2L GMC heavy—duty diesel engine. Because the 1984 through 1990 6.2L GMC heavy—duty diesel engines are carried—over from the 1983 model year and the design of the turbocharger kit has not changed, the staff concludes that turbocharger kit model 60—0002/4 HD will not adversely affect exhaust emissions from vehicles for which the exemption is requested. III. RECOMMENDATIONS The staff recommends that The Turbo Shop be granted an update as requested and that Executive Order D—180—6 be issued.

IV. TURBOCHARGER KIT DESCRIPTION The purpose of a turbocharger system is to increase the volumetric effiency of an engine by forcing more air into an engine than it would take in under stock {non—turbocharged) OEM conditions. The major components of the Turbo Shop turbocharger kit number 60—0002/4 HD are a 0.96 A/R ratio Rotomaster turbocharger, an exhaust manifold to turbocharger adaptor, intake and discharge pipes, an exhaust crossover pipe, an exhaust gas recirculation (EGR) tube and an intake/discharge bonnet. The components are packaged with installation hardware and instructions and sold as a kit. The OEM exhaust manifold (right bank only) is replaced by the exhaust manifold to turbocharger adaptor. Left bank exhaust is routed by the exhaust crossover pipe to join the exhaust manifold at the rfght bank. The turbine inlet mounts directly to the replacement exhaust manifold. Intake air is routed through the bonnet and the intake pipe to be compressed by the compressor. Compressed air is then piped back to the bonnet through the discharge pipe for injection into the engine. The EGR tube is employed to reduce the formation of oxides of nitrogen (NOx). A 3/8" tube taps into the exhaust housing of the turbine and recirculates exhaust gases into the compressed air intake pipe. Flow of exhaust gases is limited by the inside diameter of the tube. Maximum positive manifold pressure (boost) is limited to 6 psig by the size of {and the exhaust flow through) the turbine housing. No wastegate or other active boost limiting device is used. The cooling of the turbocharger is achieved by direct fan air from engine and lubricating oil from the engine passing through the unit. No modifications to the OEM tune—up specifications are required, nor permitted, when the turbocharger kit is installed.

Optional accessories that can be connected to the kit include exhaust pyrometer to measure engine exhaust temperature at the turbine inlet and an intake manifold pressure (boost) guage. v. DISCUSSTON Previous evaluation and emission testing of turbocharger kit model 60—0002/4 HD showed no adverse effect on emissions of 1983 model year GMC vehicles powered by a 6.2L GMC heavy—duty diesel engine. The applicant claims no modification to the original design of the kit is necessary for installation on 1984—1990 model year GMC vehicles powered by a 6.2L GMC heavy—duty diesel engine. Certification documents show that the 1984 through 1990 model year 6.2L GMC diesel engines are carried—over from the previous model year. This finding was verified by a GMC factory representative. Based on these considerations the staff concludes that no additional testing is required and that the device will have no adverse impact on emissions of 1983 through 1990 model year GMC vehicles powered by a 6.2L GMC heavy—duty diesel engine.
