                                     SUMMARY



      Spearco Performance Products, Inc. has requested an exemption from the

prohibitions in Vehicle Code Section 27156 for a series of their add—on

turbocharger kits, with an optional intercooler, for installation on 1982
through 1984 Toyota Supra and Cressida vehicles with a 2.8 lTiter (168 CID)

six—cylinder fuel injected engine.

      Based on the results from comparative exhaust emission tests performed

by Spearco at an independent Taboratory on a 1984 Toyota Supra, and from

confirmatory tests performed by the ARB on the same vehicle, the staff

concludes that Spearco‘s turbocharger kit (with and without the optional
intercooler) evaluated will not adversely affect exhaust emission from

vehicles for which exemption is requested.

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

an exemption as requested and that Executive Order D—140—1 be issued.

EVALUATION OF SPEARCO PERFORMANCE PRODUCTS, INC.‘S ADD—ON TURBOCHARGER KIT
WITH AN OPTIONAL INTERCOOLER FOR 2.8 LITER TOYOTA SUPRA AND CRESSIDA VEKICLES
FOR EXEMPTION FROM THE PROHIBITIONS IN VEKICLE CODE SECTION 27156 IN ACCORDANCE
WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE.

1.     INTRODUCTION

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

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

Code Section 27156 for a series of their add—on turbocharger kits.       The

turbocharger kits, which have an optional intercooler, are intended for
installation on 1982 through 1984 Toyota Supra and Cressida vehicles with a

2.8 liter (168 CID) fuel injected six—cylinder engine.       The Tist of kits and

their applications is shown in the Appendices.

       Spearco has submitted data from comparative (stock baseline versus

turbocharged with and without the intercooler installed) emission tests

conducted on a 1984 Toyota Supra at FCI International Testing Lab., in Santa

Ana, California.       Confirmatory tests were conducted on the same vehicle at the

Air Resources Board (ARB) laboratory in El Monte, California.
II.       CONCLUSION

       Based on the results from comparative exhaust emission tests performed

by Spearco at an independent Taboratory on a 1984 Toyota Supra and from

confirmatory tests performed by the ARB on the same vehicle, the staff

concludes that Spearco‘s turbocharger kits {with and without the optional
intercooler) evaluated will not adversely affect exhaust emission from

vehicles for which exemption is requested.

III.   RECOMMENDATIONS

       The staff recommends that Spearco be granted an exemption for their

add—on turbocharger kits as requested and that Executive Order D—140—1 be

issued.


IV.   TURBOCHARGER KIT DESCRIPTION AND OPERATION

      The original equipment manufacturer (OEM) exhaust manifold is replaced

by a Spearco manifold.    The turbine inlet mounts directly to the replacement

exhaust manifold.     The turbine, driven by exhaust gases, is Tinked to the

compressor by a solid shaft.     Intake air is routed from the air flow meter to

the compressor by the compressor inlet pipe.     It is then compressed and routed

into the intake plenum through the cross—over pipe.     Exhaust gases from the

turbine is routed to the catalytic converter via the exhaust downpipe.

      Lubrication and cooling of the turbocharger is provided by a steel

braided line from a tap into the main oil galley.     Oi1 from the turbocharger

is returned to the ol pan.

      Maximum positive pressure (boost) is limited to 5 psi by a wastegate

internally mounted in the housing of the turbocharger.     The wastegate is

preset so that boost pressure cannot exceed 5 psi.     In addition to the
internal wastegate, a separate intake blow—off valve is included to relieve

pressure at 7 psi in the event that the wastegate malfunctioned.

      The kit also includes a fuel enrichment device.     The device connects to
the intake manifold and coolant temperature sensor.     When boost pressure

reaches 4 psi, the device increases the electrical resistance of the

temperature sensor.    This increase in electrical resistance dictates the

vehicle‘s computer to increase the fuel flow through the injector nozzles,

thus enriching the fuel charge during boost conditions above 4 psi.

      An electronic spark retard module is employed to suppress detonation

during boost conditions or heavy lToad operations.    The module utilizes a

sensor, mounted on the intake manifold or cylinder head, to detect

detonation.   When detonation is detected, the module electronically retards

the spark until detonation is eliminated.


       An optional air/liquid intercooler system is also available from Spearco

for installation on these vehicles.     An intercooler core casting replaces the

compressor discharge cross—over casting pipe in the standard turbocharger

kit.   Liquid is circulated through this core by a separate pump actuated by

boost pressure.     When the pump is triggered, the circulation goes through the

intercooler core and through a coil mounted in front of the vehicle which is

exposed to ambient air flow.     This ambient air flow cools the fluid which is

then circulated to the intercooler core, thereby cooling the compressed air

before it enters the engine.

       No modifications to the OEM tune—up specifications are required when the

turbocharger kit is installed.     All OEM emission controls are left intact.

V.     TURBOCHARGER KIT EVALUATION

       A 1984 Toyota Supra vehicle with a 2.8 liter fuel—injected six—cylinder

engine was used for testing.     The dynamometer inertia weight and loading used

was 3375 Tbs. and 10.1 hp, respectively.

       Testing conducted by FCI International Testing Lab, under contract for

Spearco, consisted of a series of cold—start CYS—75 tests to determine exhaust

emissions in the unmodified (baseline) and turbocharged (without and with the

intercooler) configurations for comparison.     The ARB conducted confirmatory

tests at the El Monte laboratory.     A summary of the test results is tabulated

in the Appendices.

V1I.   DISCUSSION

       The applicant requested an exemption of an add—on turbocharger kit

applicable to 1982 Supra, and 1982 through 1984 Supra and Cressida Toyota

vehicles with a 168 CID engine.     The applicant is also offering an optional

intercooler system compatible with the turbocharger kit.     <In order to


demonstrate compliance with the requirements for the exemption, comparative

emissions tests were performed in order to compare unmodified (baseline)

exhaust emissions to the turbocharged configurations, without and with the

intercooler system functioning.

      Both sets (Spearco‘s and ARB‘s) of comparative (baseline versus
turbocharged/not intercooled and baseline versus turbocharger/intercooled)

exhaust emission test data show that when the turbocharger kit (with or

without the intercooler) was installed, CO and NOx emissions were

significantly reduced, while HC were not adversely affected.   This reduction

in CO and NOx emissions can be attributed to the additional ambient air

injected into the engine by the compressor, thus Teaning the fuel charge and

lowering combustion temperature.   The data also shows that the intercooler

system had no effect on exhaust emissions under the CVS test conditions.
