STATE OF CALIFORNIA AIR RESOURCES BOARD EVALUATION OF SPEARCO PERFORMANCE PRODUCTS, INC.‘S ADD—ON TURBOCHARGER KIT WITH AN OPTIONAL INTERCOOLER FOR 2.8 LITER TOYOTA SUPRA AND CRESSIDA VEHICLES FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE. FEBRUARY 1, 1983

Date of Issue: February 1, 1983 EVALUATION OF SPEARCO PERFORMANCE PRODUCTS, INC.‘S ADD—ON TURBOCHARGER KIT WITH AN OPTIONAL INTERCOOLER FOR 2.8 LITER TOYOTA SUPRA AND CRESSIDA VENICLES FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CoDE. by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue El Monte, CA 91731 (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 commerical products constitute endorsement or recommendation for use.)

SUMMARY Spearco Performance Products, Inc. has requested an exemption from the prohibitions in Vehicle Code Section 27156 for a series of their add—on turbocharger kits, with an optional intercooler, for installation on 1982 through 1984 Toyota Supra and Cressida vehicles with a 2.8 lTiter (168 CID) six—cylinder fuel injected engine. Based on the results from comparative exhaust emission tests performed by Spearco at an independent Taboratory on a 1984 Toyota Supra, and from confirmatory tests performed by the ARB on the same vehicle, the staff concludes that Spearco‘s turbocharger kit (with and without the optional intercooler) evaluated will not adversely affect exhaust emission from vehicles for which exemption is requested. The staff recommends that Spearco Performance Products, Inc. be granted an exemption as requested and that Executive Order D—140—1 be issued.

EVALUATION OF SPEARCO PERFORMANCE PRODUCTS, INC.‘S ADD—ON TURBOCHARGER KIT WITH AN OPTIONAL INTERCOOLER FOR 2.8 LITER TOYOTA SUPRA AND CRESSIDA VEKICLES FOR EXEMPTION FROM THE PROHIBITIONS IN VEKICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE. 1. INTRODUCTION Spearco Performance Products, Inc., of 7541 Woodman Place, Yan Nuys, California 91405, has requested an exemption from the prohibitions in Vehicle Code Section 27156 for a series of their add—on turbocharger kits. The turbocharger kits, which have an optional intercooler, are intended for installation on 1982 through 1984 Toyota Supra and Cressida vehicles with a 2.8 liter (168 CID) fuel injected six—cylinder engine. The Tist of kits and their applications is shown in the Appendices. Spearco has submitted data from comparative (stock baseline versus turbocharged with and without the intercooler installed) emission tests conducted on a 1984 Toyota Supra at FCI International Testing Lab., in Santa Ana, California. Confirmatory tests were conducted on the same vehicle at the Air Resources Board (ARB) laboratory in El Monte, California. II. CONCLUSION Based on the results from comparative exhaust emission tests performed by Spearco at an independent Taboratory on a 1984 Toyota Supra and from confirmatory tests performed by the ARB on the same vehicle, the staff concludes that Spearco‘s turbocharger kits {with and without the optional intercooler) evaluated will not adversely affect exhaust emission from vehicles for which exemption is requested. III. RECOMMENDATIONS The staff recommends that Spearco be granted an exemption for their add—on turbocharger kits as requested and that Executive Order D—140—1 be issued.

IV. TURBOCHARGER KIT DESCRIPTION AND OPERATION The original equipment manufacturer (OEM) exhaust manifold is replaced by a Spearco manifold. The turbine inlet mounts directly to the replacement exhaust manifold. The turbine, driven by exhaust gases, is Tinked to the compressor by a solid shaft. Intake air is routed from the air flow meter to the compressor by the compressor inlet pipe. It is then compressed and routed into the intake plenum through the cross—over pipe. Exhaust gases from the turbine is routed to the catalytic converter via the exhaust downpipe. Lubrication and cooling of the turbocharger is provided by a steel braided line from a tap into the main oil galley. Oi1 from the turbocharger is returned to the ol pan. Maximum positive pressure (boost) is limited to 5 psi by a wastegate internally mounted in the housing of the turbocharger. The wastegate is preset so that boost pressure cannot exceed 5 psi. In addition to the internal wastegate, a separate intake blow—off valve is included to relieve pressure at 7 psi in the event that the wastegate malfunctioned. The kit also includes a fuel enrichment device. The device connects to the intake manifold and coolant temperature sensor. When boost pressure reaches 4 psi, the device increases the electrical resistance of the temperature sensor. This increase in electrical resistance dictates the vehicle‘s computer to increase the fuel flow through the injector nozzles, thus enriching the fuel charge during boost conditions above 4 psi. An electronic spark retard module is employed to suppress detonation during boost conditions or heavy lToad operations. The module utilizes a sensor, mounted on the intake manifold or cylinder head, to detect detonation. When detonation is detected, the module electronically retards the spark until detonation is eliminated.

An optional air/liquid intercooler system is also available from Spearco for installation on these vehicles. An intercooler core casting replaces the compressor discharge cross—over casting pipe in the standard turbocharger kit. Liquid is circulated through this core by a separate pump actuated by boost pressure. When the pump is triggered, the circulation goes through the intercooler core and through a coil mounted in front of the vehicle which is exposed to ambient air flow. This ambient air flow cools the fluid which is then circulated to the intercooler core, thereby cooling the compressed air before it enters the engine. No modifications to the OEM tune—up specifications are required when the turbocharger kit is installed. All OEM emission controls are left intact. V. TURBOCHARGER KIT EVALUATION A 1984 Toyota Supra vehicle with a 2.8 liter fuel—injected six—cylinder engine was used for testing. The dynamometer inertia weight and loading used was 3375 Tbs. and 10.1 hp, respectively. Testing conducted by FCI International Testing Lab, under contract for Spearco, consisted of a series of cold—start CYS—75 tests to determine exhaust emissions in the unmodified (baseline) and turbocharged (without and with the intercooler) configurations for comparison. The ARB conducted confirmatory tests at the El Monte laboratory. A summary of the test results is tabulated in the Appendices. V1I. DISCUSSION The applicant requested an exemption of an add—on turbocharger kit applicable to 1982 Supra, and 1982 through 1984 Supra and Cressida Toyota vehicles with a 168 CID engine. The applicant is also offering an optional intercooler system compatible with the turbocharger kit. <In order to

demonstrate compliance with the requirements for the exemption, comparative emissions tests were performed in order to compare unmodified (baseline) exhaust emissions to the turbocharged configurations, without and with the intercooler system functioning. Both sets (Spearco‘s and ARB‘s) of comparative (baseline versus turbocharged/not intercooled and baseline versus turbocharger/intercooled) exhaust emission test data show that when the turbocharger kit (with or without the intercooler) was installed, CO and NOx emissions were significantly reduced, while HC were not adversely affected. This reduction in CO and NOx emissions can be attributed to the additional ambient air injected into the engine by the compressor, thus Teaning the fuel charge and lowering combustion temperature. The data also shows that the intercooler system had no effect on exhaust emissions under the CVS test conditions.
