State of California AIR RESOURCES BOARD Evaluation of Spearco Performance Products, Inc.‘s Air—To—Air Intercooler System for Exemption from the Prohibitions in Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. November 7, 1984

Evaluation of Spearco Performance Products, Inc.‘s Air—To—Air Intercooler System 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 commercial products constitute endorsement or recommendation for use.)

SUMMARY Spearco Peformance Products, Inc. has requested an update to the exemption from the prohibitions in Vehicle Code Section 27156, for their air—to—air intercooler system for use on the following OEM turbocharged vehicles: 1. 1984—1985 3.0L Nissan 300ZX; 2. 1984—1985 1.8L Nissan 200SX; 3. 1984—1985 2.2L Chrysler Laser/Dodge Daytona; 4. 1984—1985 2.6L Mitsubishi Plymouth and Dodge Conquest; 5. 1983—1985 2.6L Mitsubishi Starion; and 6. 1983—1985 2.3L Ford Thunderbird/Mustang. Executive Order (E.0.) D=140—3 was granted to Spearco Performance Products, Inc. on October 17, 1984 on the basis that their add—on air—to—air intercooler system did not have an adverse effect on exhaust emissions when the system is installed on the requested 1983 and 1984 OEM turbocharged vehicles. Since 1985 model—year vehicles are carry—overs from the 1983 and 1984 models, the staff concludes that Spearco‘s air—to—air intercooler system will not adversely affect exhaust emissions from vehicles for which exemption is requested. The staff recommends that Spearco Performance Products, Inc. be granted an exemption for their air—to—air intercooler system to be used on the requested vehicles and that Executive Order D—140—6 be issued.

Evaluation of Spearco Performance Products, Inc.‘s Air—to—Air Intercooler System for Exemption from the Prohibitions in Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. I. INTRODUCT ION Spearco Performance Products, Inc., of 7541 Woodman Place, Van Nuys, California 91405, has requested an update to the exemption from the prohibitions in Vehicle Code Section 27156 for their air—to—air intercooler system for use on the following OEM turbocharged vehicles: 1. 1984—1985 3.0L Nissan 300ZX; 2. 1984—1985 1.8L Nissan 200SX; 3. 1984—1985 2.2L Chrysler Laser/Dodge Daytona; 4. 1984—1985 2.6L Mitsubishi Plymouth and Dodge Conquest; 5. 1983—1985 2.6L Mitsubishi Starion; and 6. 1983—1985 2.3L Ford Thunderbird/Mustang. II. CONCLUSIONS Executive Order (E.0.) D—140—3 was granted to Spearco Performance Products, Inc. on October 17, 1984.on the basis that their add—on air—to—air intercooler system did not have an adverse effect on the exhaust emisssions when this system is installed on the requested 1983 and 1984 OEM turbocharged vehicles. Since 1985 model—year vehicles are carry—overs from the 1983 and 1984 models, the staff concludes that Spearco‘s air—to—air intercooler system will not adversely affect exhaust emissions from vehicles for which exemption is requested. III. RECQMMENDATIONS The staff recommends that Spearco Performance Products, Inc. be granted an exemption for their air—to—air intercooler system to be used on the requested vehicles and that Executive Order D—140—6 be issued.

IV. INTERCOOLER SYSTEM DESCRIPTION AND OPERATION The purpose of the intercooler is to reduce the temperature of the intake air/fuel charge going into the turbocharged engine. This reduction in the intake charge temperature allows a higher charge density (more amount of air per minute flowing through the engine) which means more fuel into the engine at a given intake manifold vacuum/pressure. The major components of the Spearco air—to—air intercooler system are a heat exchanger and inter—connecting mandrel bent tubes. They are packaged with installation hardware and instructions and sold as a kit. The system is designed using different design concepts, including tubing lengths, diameter and bends, to suit the requirements of the individual vehicle. The air—to—air heat exchanger is located in such a way that the heated charge air flow goes through one section and ambient air flows through the other section, cooling the heated, compressed charge air. The cooled compressed air is then passed out of the heat exchanger to the throttle(s) for induction into the engine. The location for the installation of the heat exchanger varies with each vehicle model. Y. DISCUSSION Spearco‘s air—to—air intercooler system was exempted from the prohibitions in Vehicle Code Section 27156 by the Executive Order (E.0.) D—140—3 dated October 17, 1984 on the basis that the use of the intercooler would not adversely affect the vehicle‘s emissions or degrade the vehicle‘s driveability. <~The applicant requested an update to this exemption to include 1985 OEM turbocharged vehicles as listed in the introduction of this report.

According to the performance analysis previously submitted to the ARB, the staff have found that the thermal efficiency of the intercooler system ranges between 40% and 84% and that the reduction in the combustion temperature, resulted from the cooler intake charge due to the installation of the intercooler system, will reduce the formation of NOx gases in the combustion chamber and, therefore, through the exhaust system. Since the engine design of the 1985 models are carried over from 1984 (and 1983 for 2.6L Mitsubishi Starion and 2.3L Ford Thunderbird Mustang) model—year vehicles, the staff is of the opinion that the 1985 vehicles will not have an adverse effect on the exhaust emissions when the Spearco‘s air—to—air intercooler system is installed. No additional testing was required or performed to update this exemption.
