SUMMARY The Turbo Shop, Inc., of 940 W. Manchester Blvd., Inglewoeod, California 90301 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for the 460 EFI Header System. The 460 EFI Header System is designed for installation on 1987—91 heavy—duty Ford vehicles equipped with a 7.5 liter (460 CID)‘fue] injected engine. Based on the results from comparative exhaust emission tests performed cat an independent laboratory on a 1991 Ford F—250 pick—up truck, the staff concludes that The Turbo Shop, Inc.‘s 460 EFI Header System will not adversely affect exhaust emission from vehicles for which an exemption is requested. The staff recommends that The Turbo Shop, Inc. be granted an exemption as requested and that Executive Order D—180—10 be issued.

EVALUATION OF THE TURBO SHOP, INC.‘S 460 EFI HEADER SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTYION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS 1. INTRODUCTION The Turbo Shop, inc. of 940 W. Manchester Blivd., Inglewood, California 90301 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code for the 460 EFI Header System. The 460 EFI Header System is designeé for instal?atiofl on 1987—91 heavy—duty Ford vehicles powered by a 7.5 liter (460 CID) fuel injected engine. The Turbo Shop, Inc. has submitted data from comparative emission tests conducted on a 1991 Ford F—250 pick—up truck at Milton Roy Laboratory, Orange, California. 11. CONCLUSION Based on the resulits from comparative exhaust emission tests performed at Milton Roy Laboratory on a 1991 Ford F—250 pick—up truck, the staff concludes that The Turbo Shop, Inc.‘s 460 EFI Header System will not adversely affect exhaust emissions from vehicles for which an exemption is requested.

V. 460 EFI HEADER SYSTEM EVALUATION AND DISCUSSION A 1991 Ford F—250 pick—up truck with a 7.5 liter (460 CID) fuel injected gasoline engine was used for the evaluation of the 460 EFI Header System. The dynamometer inertia weight and loading used were 7000—lbs and 18.2—hp respectively. Comparafive emissions tests conducted by Milton Roy Laboratory for The Turbo Shop, Inc. consisted of one Cold—Start CVS—75 emission test in the unmodified (baseline) configurétion, followed by one Cold—Start CVS—75 emission test in the modified (header system installed) configuration. The ARB . did not perform tests to confirm the test results submitted by the applicant. A summary of the test results is shown below: Exhaust Emissions Test Results On A 1991 Ford F—250 pick—up truck Test Exhaust Emissions (gm/mi) Mode HC CO NOx Baseline .803 9.551 6.291 Device .306 10 .612 6.471 Difference +.103 +1.061 +.180 % Difference +12.8% +11.1% +2.8% The differences between the device emission test results and baseline emission test results submitted by the applicant were within the allowed limits of .1 gm/mile or 10 percent of baseline HC, 1.0 gm/mile or 15 percent of baseline CO and .1 gm/mile or 10 percent of baseline NOx as specified in the "Procedures for Exemption of Add—On and Modified Parts." Based on the test | results, the staff concludes that the installation of the 460 EFI Header System did not have an adverse effect on exhaust emissions of the affected vehicles. The Turbo Shop, Inc. submitted all the required information and fulfilled the requirements for exemption.

duty Ford vehicles powered by a fuel—injected 7.5 liter (460 CID) engine. The staff also recommends that Executive Order D—180—10 be issued. IV. DEVICE DESCRIPIION The 460 EFI Header System is designed for installation on 1987—91 heavy— duty Ford vehicles powered by a 7.5 liter (460 CI1D) fuel injected engine. The 460 EFI Header System consists of exhaust manifolds and pre—catalyst piping. As with the orignial equipment manu%acturer‘s (OEM) exhaust system, the function of Turbo Shop‘s 460 EFI header system is to route exhaust gases from the two exhaust manifolds of the engine into a common pipe which then feeds to the catalytic converter. Each cylinder has a 1.75" diameter tube that combines with the adjacent tube into a 2" diameter tube. On each side of the engine, these two 2" tubes combine into a 2.25" diameter tube. Finally all the exhaust gases are then routed into a 3" tube which feeds into the pre—catalyst piping. The installation instructions are shown in Appendix A. The purpose of The Turbo Shop exhaust system is to enhance the exhaust flow through the use of steel tubing with mandrel type bending methods used. The manufacturer claims, use of mandrel—type bending method prevents the tubing fromkbeing crushed or reduced in size during the bending of the tubing, thereby allowing the engine to work more efficiently. The system operates in conjunction with the OEM computer controlled electronic port fuel injection and emission control systems already certified> with the stock engine. Installation of Turbo Shop‘s exhaust system does not alter the OEM location of the oxygen sensor and the catalyst. The tune—up specifications also remain the same. —_2.
