RECOMMENDAT IONS The staff recommends that the Turbo Shop be granted an exemption for its turbocharger kit for use on 1983—1987 Ford Motor Company heavy—duty vehicles powered by the 6.9 liter Navistar International heavy—duty diese! engine and 1988 model—year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty engine, and that Executive Order D—180 be issued.

IV. TURBOCHARGER KIT DESCRIPTION The purpose of the Turbo Shop turbocharger system is to increase the power output of the engine by increasing the volumetric efficiency of it by compressing the intake charge to pressures above that of the atmosphere. This increased pressure allows a greater charge density to enter the combustion chamber providing more oxygen for combustion. The maximum fue! delivery is slightly increased (1/4 of a turn) in order to maintain proper air—fuel! ratios with the increased air flow from the turbocharger when it is providing positive manifold pressure (boost). The major components of the system include a 1.0 A/R ratio Allied Signal Mode! No. TO4B turbocharger, custom intake adaptors, 3" diameter exhaust tubing, air cleaner assembly, brackets, hoses and the hardware necessary to complete the installation. The OEM exhaust system is replaced by a 3" diameter exhaust system. Maximum positive manifold pressure is limited to 10 psig by the size of the turbine and the compressor. The maximum engine speed is regulated by the OEM fuel! injection governor. Therefore, by controlling max Imum engine spseed, maximum turbline speed and corresponding boost pressures are also controlled. Modification to the OEM emission—related parts due to the Installation of the turbocharger kit include replacement of the air cleaner assembly and replacement of the OEM exhaust system with a 3" diameter exhaust system. The positive crankease ventlilation (PCV) vaive is relocated to allow the turbocharger installation. No other OEM emission controls are removed or disconnected when the turbocharger kit is installed.

Installation instructions, included in every kit, show the kit installer how to properly install the turbocharger system and adjust the maximum fue! delivery properly (see Appendix A). A prototype identification label is shown in Appendix B. v. URBQCHARGER KJT EVALUATION Evaluation of the Turbo Shop turbocharger kit included analysis of all submitted information to confirm that it meets the requirements for the exemption, a comparison of the submitted exhaust emissions data, and a comparison of the confirmatory emissions data generated at the Haagen—Smit Laboratory. The test vehicle was a 1987 Ford F—250 pick—up truck with an afitomatic transmission. The Turbo Shop had requested in writing that the 1988 Ford heavy—duty diesel vehicles be Included in the exemption. Based on the fact that the 1988 7.3L Navistar international heavy—duty diese! engine Is a replacement engine for the 1987 6.9L engine and both engines have similar designs and the 7.3L engine design complies with the carryover criteria as outlined in EPA‘s Advisory Circulars 17F and 20B, the 1988 7.3L engine is included In the exemption. The Turbo Shop performed comparative exhaust emissions tests at Olson Enginsering, inc., in Huntington Beach, California, on a 1987 Ford F—250. The test program used was the "Test Program for Add—on Turbocharger Kits for Heavy—Duty Engines" (see Appendix C). The results of these tests are shown in Table 1.

The Olson Engineering test results show Iincreases in HC emissions and the results of the confirmatory testing show increases in HC and CO emissions with the turbocharger installed. Although these increases seem to be significant in percentage, they are not significant in magnitude. Based on that, the staff believes that the installation of the Turbo Shop 6.9L/7.3L turbocharger kit will not have significant adverse effects on the exhaust emissions from the vehicles for which exemption is requested.

Reconnect negative battery cables and start vehicle. DO NOT REV ENGINE, ALLOW TO IDLE FOR &A FEW MINUTES. During this time check all connections for leaks and proper operation of gauges installed. Stop engine and repair as necesseary. EXHAUST SYSTEM We have designed an exhaust system to give you maximum ‘performance with the turbo system. The next best possible exhaust system would be a 3" exhaust with a quality low restriction muffler . CAUT ION Excessive backpressure will result in high exhaust temperature. Under no conditions should the exhaust temp. rise above 1190 deg. F. serious engine damage may occur! —10—

APPENDIX & (CONTINUED) INJECTOR PUMP ADJUSTMENT To obtain maximum performance from your turbe system it is necessary to make an injector pump adjustment. This adjustment increases the total amount of fuel delivery to the engine. This with the increased supply of air provided by the turbocharger will give you power gains of as much as 40%. Cleanliness is the most important thing to remember when the pump is being adjusted. Do not allow any foreign material to enter the injector pump during this adjustment. First place a drippan under the vehicle under the flywheel inspection cover area too catch the fuel released during adjustments. Locate the cover on othe passengerside of the injector pump, it is secured by two screws. Using a 1/4" wrench losgen the lower screw and remove the upper. This will allow you to rotate the cover and gasket out of the way for access to the adjusting screw,. Rotate the engine in a clockwise direction by HAND ONLY until the allen head screw appears inside the pump. Center the screw in the opening before trying too adijust it, using a light and mirror will make see the screw much easier. Using a 5732" allen wrench adjust the screw inward ¢clockwise when looking at the screw) will increase fuel flow and increase exhaust temp. ,— outward (counterclockwise> to decrease fuel flow and lower exhaust temp. . Under no circumstance should the screw be rotated inward more than 1/3 of a turn from it‘s original setting. WE RECOMMEND AN INCREASE OF i/4 TURN INWARD. THIS I1§S THE ONLY SETTING LEGAL IN THE STATE OF CALIFORNIA. Increases of more than 1/4 of a turn up to 1/3 turn are for HIGH PERFORMANCE USE ONLY. Exhaust temperature must not exceed 1150 degree fahrenheit as shown on the pyrometer furnished with this kit. If this temperature approaches under heavy uphil1 load reduce epeed and use a lower gear. If vehicle continually reaches this temperature a reduction in the injector pump setting is necessary! THINGS TO REMEMBER 1. Keep air cleaner element clean. When the element becomes dirty remove from holder and clean per manufactures instructions. A dirty air cleaner will cause excessive oil consumption and high exhaust temperatures. 2. Change oil and filter every 2500 miles. 3. Before shutting engine off make sure exhaust temperature 11—

APPENDIX & (CONTINUED) is below 300 degrees fahrenheit. 4. When etarting your engine do not rev the engine! Allow the engine to idle and warm up before driving. Foilowing these easy directicons will give you many trouble free miles of enjoyment from your turbo system. ~12—

STEADY STATE TESTS 1) (Idle 2) 20, 30, 40, 50 and 55 mph at 1XRL. Prior to measuring exhaust emission at any steady state test point, the vehicle‘s engine temperature shall be stabilized. This is satisfied when engine oil temperature is stabilized as monitored and indicated by a temperature recorder. If a steady state point is unattainable in the baseline configuration, then the last point at a specified horsepower should be WOT and the speed should be recorded. The test in the turbocharged configuration will be performed at the same speeds and horsepower as the baseline configuration. > Any steady state may be deleted if 1) the steady state exceeds or can be expected to exceed the engine redline or 2) steady state conditions might cause serious damage to vehicle components or dynamomter, ‘or create a hazard for test personnel. STEADY STATE DATA REQUIREMENTS 1) CO concentration 2) C072 concentration ) HC concentration to ) NOx concentration oo ) engine rom on 6) engine oil temperature MISCELLANEOUS 1) The same fuel will be used for both the unmodified and modified configurations unless the turbocharger manufacturer‘s written instructions specify a different fuel for the turbocharged configuration. ~14—

APPENDIX C (CONTINUED) Tire pressure in the drive wheels will be the maximum indicated on the tire sidewall. Test vehicles from secondary manufacturers may be tested without a body shell if 1) the cab is intact, 2) the vehicle is legally driveable on the street, 3) the frontal area is identical to the built—up vehicle, 4) the chassis is loaded to a weight simulating loaded vehicle weight. Loaded vehicle weight is defined as the manufacturer‘s estimated weight of the vehicle in operational status with all standard equipment, the weight fuel at nominal tank capacity, and the weight of optional equipment. j «15—
