Evaluation of Spearco Performance Products, Inc., Modified Air—To—Air Intercooler Systems for 1987 and 1988 Intercooled Toyota Turbo Supra Vehicles Powered by a 3.0 Liter Engine 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 Alr 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 Performance Products, Iinc. (Spearco) has requested exemption from the prohibitions in California Vehicle Code Section 27156 for their modified air—to—air intercooler systems to be used on the 1987 and 1988 intercooled Toyota Turbo Supra vehicles powered by a 3.0 liter engine with original equipment manufacturer (OEM) turbochargers and intercoolers. Based on previous comparative tests evaluating the exhaust emission effects of several add—on intercooler systems and the staff‘s engineer ing evaluation of the intercooler‘s impact on exhaust emissions from turbo— charged vehicles, the staff concludes that Spearco‘s modified air—to—air intercooler systems will not adversely affect exhaust emissions from vehicles for which exemption is requested. The staff recommends that Spearco be granted an exemption for their modified air—to—air intercooler systems as requested and that Executive Order D—140—22 be issued.

Evaluation of Spearco Performance Products, inc., Modified Air—To—Air Intercooler Systems for 1987 and 1988 Intercooled Toyota Turbo Supra Vehicles Powered by a 3.0 Liter Engine for Exemption from the Prohibitions in Vehicle Code Section 27156 in Accordance with Section 2222, Title 13 of the California Administrative Code. 1. 1INTRODUCT Spearco Performance Products, Inc. (Spearco), of 7541 Woodman Place, Van Nuys, California 91405, has requested exemption from the prohibitions in California Vehicle Code Section 27156 for their modified air—to—air intercooler systems to be used on the 1987 and 1988 intercooled Toyota Turbo Supra vehicles powered by a 3.0 liter engine with OEM turbochargers and intercoolers . 1. N LON Based on previous comparative tests evaluating the exhaust emission effects of several add—on intercooler systems and the staff‘s engineer ing evaluation of the intercooler‘s impact on exhaust emissions from turbocharged vehicles, the staff conciudes the Spearco‘s modified air—to—air intercooler systems wil! not adversely affect exhaust emissions from vehicles for which exemption is requested. L1 . E NDA N The staff recommends that Spearco be granted an exemption for their modified air—to—air intercooler systems and that Executive Order D—140—22 be issued. IV. NTER YSTEM D RIPT 1 AND OPERAT ION 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 modified air~to—air intercooler system are a heat exchanger and inter—connecting rubber and stéel bent tubes. They are packaged with installation hardware and instructions and sold as a system. 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. v. L LQN Spearco has previously been issued a number of exemptions for several of their air—to—air intercooler systems for installation on limited 1987 and older model—year vehicles. The previous exemptions were granted on the basis that the use of the intercooler system would not adversely affect the vehicle‘s emlssions or degrade the vehicle‘s driveability. According to the performance analysis previously submitted to the Air Resources Board by Spearco and other manufacturers seeking exemption, the staff have found that the thermal efficiency of the intercooler system ranges between 40% and 84%. Based on predicted efficiency of a heat exchanger on previous air temperature measurements of two exempted intercoolers installed, tests on two vehicles, and a review of the device theory of operation, the staff has concluded that the use of an intercooler would not adversely affect vehicle emissions or result in the degrading of a vehicle‘s driveability.

In addition, it is the staff‘s opinion that the combustion temperature will be reduced as a result of cooler intake charge with use of the air—to—air intercooler system. This reduction in combustion temperature will reduce the formation of NOx gases in the combustion chamber, resulting in less NOx emissions expelied through the exhaust system. The Spearco modiffied intercooler replaces the OEM intercooler. It is similar to the OEM unit in form, fit, and function, except at higher engine operating RPMs where the Spe;rco unit is more efficient. This higher efficiency is due to the lower (24% compared to OEM, according to Spearco) pressure drop across the intercooler. Spearco also claims that their modified Intercooler reduces the charge air temperature approximately 22% (compared to the OEM unit).
