SUMMARY The Turbo Shop, Inc. (Turbo Shop) has applied for an update to Executive Order D—180—4 which exempts their air—to—air intercooler Kit from the prohibitions of Vehicle Code Section 27156. The existing exemption applies to 1983—1987 model year Ford Motor Company vehicles powered by a 6.91 Navistar International heavy—duty diesel engine and 1988—1990 model year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. The update is requested to include the 1991 model—year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. Because Turbo Shop, Inc. was granted an exemption for 1988—1990 model year 7.3L Navistar International heavy—duty diesel vehicles and the 1991 model year 7.3L heavy—duty diesel engine is a carry—over from the previous model years, the staff concludes that Turbo Shop, Inc.‘s add—on air—to—air intercooler 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—8 be issued.

EVALUATION OF THE TURBO SHOP, INC.‘S ADD—ON AIR—TO—AIR INTERCOOLER KIT FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS. I. INTRODUCTION The Turbo Shop, Inc. (Turbo Shop) of 940 West Manchester, Inglewood, CA 90301, has applied for an update to Executive Order D—180—4, which exempts their air—to—air intercooler kit model from the prohibitions in Vehicle Code Section 27156. The exemption applies to 1983—1987 model year Ford Motor Company vehicles powered by a 6.9L Navistar International heavy— duty diesel engine and 1988—1990 model year Ford Motor Company vehicles powered by a 7.31 Navistar International heavy—duty diesel engine. The update is requested to include the 1991 mode]l year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. II. CONCLUSION Based on the following: (1) an exemption has been granted for the installation of the Turbo Shop‘ s air—to—air intercooler system on 1988—1990 model year 7.3L Navistar International heavy—duty diesel vehicles; (2) the 1991 mode?! year 7.3L heavy—duty diesel engine is a carry—over from previous model years; (3) previous comparative tests evaluating emission effects of several add—on intercooler systems and the staff‘s technical evaluation of the intercooler‘s impact on exhaust emissions, the staff concludes that Turbo Shop‘s add—on air—to—air intercooler kit will not adversely affect exhaust emissions from vehicles for which the exemption update is requested. III. RECOMMENDATIONS The staff recommends that The Turbo Shop be granted an update as requested and that Executive Order D—180—8 be issued.

IV. INTERCOOLER_KITDESCRIPTION The purpose of the Turbo Shop intercooler system is to reduce the temperature of the intake air that is charged into the turbocharged engine. A reduction in the intake air temperature allows a greater charge density (more mass of air flowing through the engine) to enter the combustion chamber. This means more fuel into the engine at any given manifold pressure and, therefore, more power output from the engine. Also, the reduction in the intake charge temperature results in lower combustion/exhaust temperature. The major components of the system include an air—to—air heat exchanger and inter—connecting bent tubes. The compressed air from the turbocharger enters through one section of the heat exchanger and ambient air, as a cooling medium, flows through the other section, cooling the heated compressed charge air. The cooled compressed air then passes out of the heat exchanger to the throttle(s) for induction to the engine. A pressure drop occurs when the compressed air passes through the heat exchanger which varies depending on the size of the heat exchanger, the temperature of the cooling medium {ambient air) and the available flow rate of the cooling medium. The inlet and outlet pipes of the Turbo Shop‘s air—to—air intercooler system are made from 2—1/4" and 2—1/2" steel tubing, respectfully. The length of the tubing varies according to the model—year of the engine. No emission control components are removed, disconnected or relocated when the air—to—air intercooler kit is installed.

v. DISCUSSION Turbo Shop‘s add—on air—to—air intercooler kit model is designed for installation on 1983—1987 model year Ford Motor Company vehicles powered by a 6.9L Navistar International heavy—duty diesel engine and 1988—1991 model year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. The applicant claims that no modifications to the kit is necessary for the installation on 1991 mode] year applicable vehicles. According to performance analysis previously submitted by other manufacturers seeking exemption, the thermal efficiency of the intercooler system ranges between 40 percent to 84 percent. Based on predicted efficiency of a heat exchanger and a review of the intercooler system, the staff believes that the Turbo Shop‘s add—on air—to— air intercooler kit will not adversely affect a turbocharged vehicle‘s emissions or degrade a vehicle‘s driveability.

No emission control components are removed, disconnected or relocated when the air—to—air intercooler kit is installed.

v. DISCUSSION © Turbo Shop‘s add—on air—to—air intercooler kit model is designed for installation on 1989—1991 model year Dodge vehicles powered by a 1990 5.91 Cummins 6BT heavy—duty diesel engine with a manufacturer production date of February 1, 1991 or earlier. The applicant claims that no modifications to the kit are necessary for the installation on 1991 model year applicable vehicles. Dodge vehicles manufactured after February 1, 1991 will not be equipped with the Cummins 687 engine. The 1991 model year Cummins heavy— duty diesel engine has a new model number and comes equipped with an intercooler system. According to performance analysis previously submitted by other manufacturers seeking exemption, the thermal efficiency of the intercooler system ranges between 40 percent to 84 percent. Based on predicted efficiency of a heat exchanger and a review of the intercooler system, the staff believes that the Turbo Shop‘s add—on air—to—air intercooler kit will not adversely affect a turbocharged vehicle‘s emissions or degrade a vehicle‘s driveability.
