                                        SUMMARY




        Spearco Performance Products,       Iinc.   (Spearco) has requested exemption

from the prohibitions    in California Vehicle Code Section 27156           for   their

modified air—to—air      intercooler systems to be used on the 1987 and 1988

intercooled Toyota Turbo Supra vehicles powered by a 3.0          liter   engine with

original equipment manufacturer (OEM) turbochargers and intercoolers.

        Based on previous comparative tests evaluating the exhaust           emission

effects of several      add—on    intercooler systems and the staff‘s engineer ing

evaluation of the   intercooler‘s       impact on exhaust emissions from turbo—

charged vehicles,    the staff concludes that Spearco‘s modified air—to—air

intercooler systems will         not   adversely affect exhaust     emissions     from

vehicles for which exemption is requested.

        The staff recommends that Spearco be granted an exemption for             their

modified air—to—air      intercooler systems as requested and that Executive

Order D—140—22 be   issued.

1.        1INTRODUCT

          Spearco Performance Products,          Inc.   (Spearco), of 7541 Woodman Place,

Van Nuys, California 91405, has requested exemption from the prohibitions                  in

California Vehicle Code Section 27156 for                  their      modified   air—to—air

intercooler systems to be used on the 1987 and 1988                  intercooled Toyota Turbo

Supra vehicles powered by a 3.0          liter engine with OEM turbochargers and

intercoolers .

1.             N   LON

          Based on previous comparative tests evaluating the exhaust emission

effects of several add—on         intercooler systems and the staff‘s engineer ing

evaluation of        the       intercooler‘s     impact    on   exhaust     emissions from

turbocharged vehicles, the staff conciudes the Spearco‘s modified air—to—air

intercooler        systems wil!      not adversely affect exhaust emissions from

vehicles for which exemption         is requested.

L1 .       E       NDA     N

          The staff recommends that Spearco be granted an exemption for                their

modified air—to—air        intercooler systems and that Executive Order D—140—22 be

issued.

IV.        NTER            YSTEM D    RIPT 1     AND    OPERAT ION

          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 flowing through the engine) which means more fuel                  into the

engine at a given intake manifold vacuum/pressure.


         The major components of the Spearco modified air~to—air            intercooler

system are a heat exchanger and          inter—connecting rubber       and stéel          bent

tubes.   They are packaged with          installation hardware and     instructions and

sold as a system.

         The air—to—air     heat exchanger      is   located    in such a way that the

heated charge air       flow goes    through one section and ambient           air    flows

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

cooled compressed air       is then passed out of       the heat    exchanger        to    the

throttle(s) for    induction   into the engine.

v.        L       LQN

         Spearco    has previously been        issued a number of exemptions for

several of their air—to—air        intercooler systems for     installation on    limited

1987 and older model—year vehicles.        The previous exemptions were granted on

the basis that the use of the        intercooler system would not adversely affect

the vehicle‘s emlssions or degrade the vehicle‘s driveability.            According to

the performance analysis previously submitted to the Air Resources Board by

Spearco and other manufacturers seeking exemption, the staff have found that

the thermal efficiency of the 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,     tests on

two vehicles, and 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 driveability.


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

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

         The Spearco modiffied         intercooler replaces the OEM      intercooler.      It

is similar to the OEM unit          in form,   fit,   and   function,   except    at   higher

engine operating RPMs where the Spe;rco unit            is more efficient.       This higher

efficiency   is due to the    lower    (24% compared to OEM,     according to Spearco)

pressure drop across the            intercooler.      Spearco also claims that          their

modified Intercooler reduces the charge air            temperature approximately 22%

(compared to the OEM unit).
