HKS    USA,    Inc.    (HKS)      has     requested       an    exemption       from    the

prohibitions          of    Vehicle       Code    Section       27156    for    their       air—to—air

intercooler       system for use on the OEM turbocharged vehicles

listed    in    the    appendix.




Based    on    previous       comparative          tests       evaluating       the    exhaust

emission       effects       of   several        add—on    intercooler          kits    and    the

staff‘s engineering               evaluation of           the    intercooler‘s          impact       on

exhaust       emisslons       from      turbocharged           vehicles,       the    staff    concludes

that    the    HKS‘s       air—to—air       intercooler          kit    wilt    not    adversely

affect    exhaust          emisslons       from vehicles          for    which       exemption       is

requested.




The    staff    recommends         that     HKS USA,       Inc.    be    granted       an   exemption

for    their   air—to—air          Intercooler        system as          requested and          that

Executive      Order       D—186     be    Issued.

Based on          previous            comparative        tests      evaluating         the    exhaust
emission          effects of            different        add—on         intercooler         kits    and       the

affect       exhaust            emissions          from vehicles for            which exemption                is

III.    RE         MENDAT 1


The    staff       recommends               that   HKS   USA,      Inc.   be    granted      an     exemption
for    their       air—to—air               intercooler       system      as    requested          and    that
Executive Order                  D—186 be          issued.


LV .         1      R         LER     SYSTEM       DESCR!           ION AND        OPERATION


The purpose of                 the    intercooler              is    to reduce       the      temperature of
the     Iintake         air/fue!          charge       going        into    the    turbocharged            engine.
This     reductlon             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       glven    intake
manifold vacuum/pressure.


The major           components of                the HKS air—to—air                 intercooler            system
are:     aluminum heat exchanger, pressure pipes,                                        cadmium plated
brackets, sillcone connector hoses, hose clamps,                                               compressor by—
pass valve, silicone vacuum and blow—by hoses.                                                 They are packaged
with     installation hardware and                             instructions and sold as a kit.
The system              Is designed using different design concepts,                                           including
tubing           lengths, diameter and bends,                          to sult the requirements of
the     individual             vehlcle.


The HKS air—to—air                    Intercooler              system heat          exchanger            is mounted
In     the       vehicies‘          frontal       air.    stream.           The    intercooler            is   spliced
Into     the       original          intake       air     plumbing          between      the       turbocharger
compressor              and    the    intake manifold throttle body.                                   During boost
conditions,              compressed air,                 normally          230 degrees F,               is cooled      to
130     degrees          F    by    the    HKS    Intercooler              core    being      delivered         to    the
engine .           Some       HKS    intercooler              systems       incorporate            a    compressor
by—pass valve which                       routes compressor                 discharge directly                 into    the
compressor              intake       under       deceleration.              This    arrangement            prevents
impeller          deceleration              between           gear   shifts        and   reduces          shock      waves
in     intercooler             plumbing          and     core.                                                           ‘


v.           D |              |


HKS air—to—air                    intercooler          system          is similar          in    design concepts
and    principles                 as other          manufacturers‘                systems       that    have       been
exempted           by    the       Air       Resources       Board.           Performance          analyses          that
were    previously                 submitted          to    the ARB          by other       manufacturers of
similar          system           indicated          that    typlcal          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 other                                      exempted          intercoolers          installed
and tested on 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 emlissions or                     result       in    the
degrading           of    a       vehicle‘s          driveabillty.


In    addition,           1t       is       the    staff‘s    opinion             that    the    combustion
temperature wlll                       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.


HKS    air—to—air                 intercooler          system          has    similar       design          with    Spearco
alr—to—alr              intercooler                system which          is exempted by                the ARB under
E.0.    D—140—3.                  Spearco‘s          previous          test       results       demonstrate          no
adverse          effect           on    the       vehicle‘s       exhaust          emissions of             their    kit.
