                                 summary

      K. F. Industries, Inc. (KFI) has requested an update to the

existing exemption from the prohibitions in Vehicle Code Section 27156

for their MAX—25 supercharger kit.    The request is to include the 1986

model—year AMC light—duty trucks powered by a GMC 2.8 liter V—6 gasoline

carbureted engine in the exemption.

      Previously KFI was granted an exemption (Executive Order D—150) for

the same MAX—25 supercharger kit for installation on 1985 and older

model—year Cheyrolet, GMC or AMC light—duty trucks powered by a GMC 2.8

liter V—6 gasoline carbureted engine.

      Certification documents show that the 1986 AMC light—duty trucks

powered by the GMC 2.8 liter V~—6 engines is a carry—over engine and

utilizes the same emission control systems as the 1985 vehicles.     The

staff is of the opinion that the 1986 vehicles will have the same degree

of performance/emissions impact as the previous model years with the

MAX—25 supercharger kit installed.

      The staff recommends that K. F. Industries, Inc. be granted an

exemption as requested and that Executive Order D—150—1 be issued.

EVALUATION OF K. F. INDUSTRIES, INC.‘S MAX—25 SUPERCHARGER KIT FOR
EXEMPTION FROM THE PROKIBITIONS IN VEHICLE CODE SECTION 27156 IN
égggRDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE


I.     INTRODUCTION

       K. F. Industries, Inc., (KFI) of Sun Valley, California 91353, has

requested an update to the existing exemption from the prohibitions in

Vehicle Code Section 27156 for their MAX—25 supercharger kit.     The

request is to include in the exemption the 1986 model—year AMC light—duty

trucks powered by a GMC 2.8 liter V—6 gasoline carbureted engine.

       KFI has previously submitted data from comparative ({stock baseline

vs supercharged) emission tests conducted on a 1984 GMC S—15 pick—up

truck at Fairway Environmental Engineering, Inc., Torrance, 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 KFI, the confirmatory tests performed by the ARB on the same

vehicle, and the fact that the engines used in the 1986 AMC lTight—duty

trucks are carry—over from 1985, the staff concludes that KFI‘s

supercharger kit will not adversely affect exhaust emission from vehicles

for which exemption update is requested.

III.   RECOMMENDATIONS
       The staff recommends that K. F. Industries, Inc. be granted an

updated exemption for their add—on turbocharger kit for installation on

1985 and older model—year Chevrolet or GMC light—duty trucks and 1986 and

older model—year AMC light—duty trucks powered by a GMC 2.8 liter V—6

gasoline carbureted engine.   The staff also recommends that Executive

Order D—150—1 be issued.


IV,   SUPERCHARGER KIT DESCRIPTION

      The MAX—25 Supercharger Kit has been specifically designed for

installation on the GMC 2.8 liter, V—6 gasoline fueled engine.     The

supercharger is belt driven and runs at 1.7 times the speed of the

engine.   The kit operates in conjunction with the OEM carburetor and the

emission control systems already certified with the stock engine.        All

the necessary hardwares and supplies are included in the kit.     A complete

manual describing the parts, and step—by—step installation procedure is

supplied with the kit.   Some of the OEM parts are removed and discarded

to be replaced by custom parts supplied with the kit.

      Lubrication and cooling of the supercharger is provided by a high

pressure hose with a swivel fitting teed to the oil pressure switch

connection.   The other end of this hose is connected to the supercharger

bearing house.   At the opposite end bearing of the supercharger the

return oil hose is connected and drains the return ofl into the rocker

cover through a special fitting.

      The maximum positive pressure boost of 5 psig at 5000 engine RPM is

limited by the ACM—30 computer, supplied in the kit, by controlling the

distributor spark advance curve above 5000 rpm.     This electronic computer

module is also employed to suppress detonation during boost conditions or

heavy operations.   It utilizes a sensor, mounted on the intake manifold

or cylinder head, to detect detonation (pinging).    When detonation is

detected, the module electronically retards the spark advance until

detonation is eliminated.

      The kit utilizes the OEM fuel enrichment system.    The ACM—30

computer also connects to a new manifold absolute pressure sensor,

supplied in the kit, and to the oxygen sensor circuit.    When boost


pressure reaches 4 psig, the ACM—30 increases the electrical resistance

of the oxygen sensor circuit.     This increase in electrical resistance

dictates the vehicle‘s computer to increase the fuel flow through the

mixture control valve in the carburetor, thus enriching the air—fuel

mixture during the boost conditions above 4 psig.

V¥.      SUPERCHARGER KIT EVALUATION

         A 1984 GMC S—15, Yight—duty pick—up truck with a 2.8 liter, V—6

gasoline carbureted engine was used for the evaluation of the K. F.

Industries, Inc.‘s MAX 25 supercharger kit.     For more detailed

information on the supercharger kit evaluation and the results of the

comparitive emissions tests performed, refer to the October 1984 staff

report "EVALUATION OF K. F. INDUSTRIES, INC.‘s MAX—25 SUPERCHARGER KIT
FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN

ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE

CODE."
         The 1985 Chevrolet, GMC and AMC vehicles were included in the

exemption (E.0. No. D—150) previously granted to KFI because the

certification documents showed that the emission control systems are the

same and were carry—over from 1984.    For 1986, the Chevrolet and GMC

light—duty trucks powered by the GMC 2.8 liter V—6 gasoline engines are

equipped with electronic fuel injection and their emission control

systems were not carry—over from 1985.     However, the 1986 AMC light—duty

trucks powered by the GMC 2.8 liter V—6 gasoline engines are equipped

with the same closed—loop carburetion system as the previous

model—years.    For this reason KFI requests that their Executive Order

D—150 be superceeded by Executive Order D—150—1 which will    include the

1986 AMC light—duty trucks.


VI.   DISCUSSION

      The previously issued Executive Order D—150 for KFI‘s MAX—25

supercharger kit was issued because the kit did not show any adverse

effects on the emissions from the vehicles for which it was designed.

The 1986 model—year AMC light—duty trucks powered by the 2.8 liter V—6

gasoline carbureted engines have been evaluated and determined to be

identical to the previous model years.    For this reason the staff

believes that the MAX—25 supercharger kit installed on the 1986

model—year AMC light—duty trucks will have the same degree of

performance/emissions impact as the vehicles included in the previous

exemption.    No additional testing was performed because neither the

vehicle configuration nor the design of the MAX—25 supercharger kit was

changed.     1986 will be probably be the last year of the carbureted GMC

2.8 liter V—6 engines for light—duty trucks.     In 1987 it is very lTikely

that AMC will also equip this engine with fuel injection.     Should KFI

seek exemption for the MAX—25 supercharger kit for installation on the

fuel—injected vehicles additional testing would be required.

      The staff concludes that Executive Order D—150 should be superseded

by Executive Order D—150—1 which will include the 1986 model—year AMC

light—duty trucks.
