EVALUATION OF THE TURBO SHOP, INC.;S ADD—ON AIR—TO—AIR INTERCOOLER KIT FOR INSTALLATION IN 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 7.3L NAVISTAR INTERNATIONAL HEAYVY—DUTY DIESEL ENGINE 1. INTRODUCTION The Turbo Shop, Inc. (Turbo Shop) of 940 West Manchester, Inglewood, CA $0301, has applied for an update to Executive Order D—180—2, which exempts their air—to—air intercooler kit from the prohibitions in Vehicle Code Section 27156. The existing exemption is applicable to 1983—1987 model year Ford Motor Company vehicles powered by a 6.9L Navistar International heavy—duty diesel engine and 1988—1989 model year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. The update is requested to include the 1990 model year Ford Motor Company vehicles powered by a 7.3L Navistar International héavy-duty diesel engine in the exemption. 41. CONCL—USION — | Bgs;d on the fo]]owifig: {1) an exemption has been granted for the installation of the Turbo Shop‘s air—to—air intercooler system on 1988—1989 model year 7.3L Navistar International heavy—duty diesel vehicles; {(2) the 1990 model 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 from turbocharged vehicles both showed no significant increase in emissions, the staff concludes that Turbo Shop‘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.

III. RECOMMENDATIONS The staff recommends that Turbo Shop be granted an update as requested and that Executive Order D—180—4 be issued. IV. INTERCOOLERKITDESCRIPTION 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 of 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 vair, as acooling medium, flows thro&gh the other Section,rcob}ing 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, respectively. 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.

60A V. DISCUS$ION Turbo Shop‘s add—on air—to—air intercooler kit 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—1990 model! year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. The applicant claims that no modification to the kit is necessary for installation on 1990 model year applicable vehicles. According to performance analysis previously submitted by other manufacturers seeking exemption, the thermal efficiency of the intercooler system ranges between 40% to §4%. 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.
