                                     SUMMARY



      Spearco Peformance Products, Inc. has requested exemption from the

prohibitions in Yehicle Code Section for their air—to—air intercooler system

for use on the following OEM turbocharged vehicles:


         1.   1984 3.0L Nissan 3007%;
         2.   1984 1.8L   Nissan 200SX;
         3.   1984 2.2L   Chrysler Laser/Dodge Daytona;
         4.   1984 2.6L   Mitsubishi Plymouth and Dodge Conquest;
         5.   1983—1984   2.6L Mitsubishi Starion; and
         6.   1983—1984 2.3L Ford Thunderbird/Mustang.



    Based on previous comparative tests evaluating the exhaust emission

effects of several add—on intercooler kits and the staff‘s engingering

evaluation of the intercooler‘s impact on exhaust emissions from turbocharged

vehicles, the staff concludes that Spearco‘s air—to—air intercooler kit 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 as requested and that

Executive Order D—140—3 be issued.

Accordance with Section 2222, Title 13, of the California Administrative Code.



I.     INTRODUCTION

       Spearco Performance Products, Inc., of 7541 Woodman Place, Van Nuys,

California 91405, has requested an exemption from the prohibitions in Vehicle

Code Section 27156 for their air—to—air intercooler system for use on the

following OEM turbocharged vehicles:



                             1984 3.0L Nissan 300ZX;

                             1984 1.8L Nissan 200SX;
                             1984 2.2L   Chrystier Laser/Dodge Daytona;
                             1984 2.6L   Mitsubishi Plymouth and Dodge Conquest;
               &




                             1983—1984   2.6L Mitsubishi Starion; and
                     .       1983—1984   2.3L Ford Thunderbird/Mustang.


I1I.   CONCLUSIONS

       Based on previous comparative tests evaluating the exhaust emission

effects of different add—on intercooler kits and the staff‘s engineering

evaluation of the intercooler‘s impact on exhaust emissions from turbocharggd

vehicles, the staff concludes that Spearco‘s air—to—air intercooler system

will not adversely affect exhaust emissions from vehicles for which‘exemption

is requested.

1II.   RECOMMENDATIONS                                  .

       The staff recommends that Spearco Performance Products, Inc. be granted

an exemption for their air—to—air intercooler system as requested and that

Executive Order D—140—3 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 filowing 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 anq inter—connecting mandrel bent tubes.     They are packaged

     with installation hardware and insfructions 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 ambijent air flows through the

     other section, cooling the heated, compressed charge air.     The cooled

     compressed air is then passed out of the heat exphanger to the throttle(s}) for
ww
     induction into the engine.     This charge temperature reduction results from the

     pressure drop across the long sweeping tube bends.    The location for the

     installation of the heét exchanger varies with each vehicle model.

     ¥.    DISCUSSION

           Spearco‘s air—to—air intercooler system is similar in design concepts

     and principles as another manufacturer‘s systems that have been exempted by

     the Air Resources Board.     Performance analyses have been previously submitted

     to the ARB indicating tfiat typical thermal efficiency of a turbocharger

     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 and tests on two vehicles and on 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 driveabiity.

           In addition, it is the staff‘s opinion that the combustion temperature

     will be reduced as a result of cooler intake charge with the 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 expelled through the exhaust system.

           Spearco air—to—air intercooler system has similar design with Spearco

     water—to—air intercooler system, which is exempted by the ARB under E.0.

     D—140—3, except that it (water—to—air intercooler) uses circulating coolant to

     reduce the intake air temperature.   Spearco‘s previous test results

     demonstrate no adverse effect on the vehicle‘s exhaust emissions of their kit.
