                 Relating to Exemptions Under Section 27156
                              of the Vehicle Code


                               DINAN ENGINEERING
                           DINAN SUPERCHARGER SYSTEM


Pursuant to the authority vested in the Air Resources Board by Section 27156
of the Vehicle Code; and

Pursuant to the authority vested in the undersigned by Section 39515 and
Section 39516 of the Health and Safety Code and Executive Order G—45—9;

IT IS ORDERED AND RESOLVED:   That the installation of the Dinan Supercharger
System, designed to a maximum boost pressure of 5.5 psi., with a
supercharger pulley diameter of 3.12" and a crankshaft pulley diameter of
§.10", manufactured by Dinan Engineering, 150 S. Whisman, Building "E",
Mountain View, California 94041 has been found not to reduce the
effectiveness of the applicable vehicle pollution control system and,
therefore, is exempt from the prohibitions of Section 27156 of the Vehicle
Code for the following BMW 8 cylinder vehicle applications:   1994/95 530T,
5301 & 540i, 1993—95 7401 & 8401.

This Executive Order is valid provided that the installation instructions
for the Dinan Supercharger System will not recommend tuning the vehicle to
specifications different from those of the vehicle manufacturer.

Installation of the superchargers requires the replacement of the factory
Lucas fuel injectors with Lucas model # 5207009 (28.8 lb./Kr.) injectors, a
replacement ECU—PROM, K & N air filter, a resistor placed in the airflow
meter bridge circuit, the removal of a stock pop—off valve located on the
intake manifold, new fue! pump, and the relocation of the PCV tube from the
intake manifold to the supercharger inlet.

Changes made to the design or operating conditions of the Dinan Supercharger
System, as exempt by the Air Resources Board, which adversely affect the
performance of a vehicle‘s pollution control system shall invalidate this
Executive Order.

Marketing of the Dinan Supercharger System using any identification other
than that shown in this Executive Order or marketing of the Dinan
Supercharger System for an application other than those listed in this
Executive Order shall be prohibited unless prior approval is obtained from
the Air Resources Board. Exemption of the Dinan Supercharger System shall
not be construed as an exemption to sell, offer for sale, or advertise any
component of the kit as an individual device.

This Executive Order does not constitute any opinion as to the effect that
the use of the Dinan Supercharger System may have on any warranty either
expressed or implied by the vehicle manufacturer.


Dinan Engineering                                  EXECUTIVE ORDER D—176—9
                                                   (Page 2 of 2)


This Executive Order is granted based on an evaluation of emissions impact
if emissions tests were conducted in accordance with Cold—Start CVS—75
Federal Test Procedure.   However, the ARB finds that reasonable grounds
exist to believe that use of the Dinan Supercharger System series may
adversely affect emissions of motor vehicles when operating under conditions
outside the parameters of the previously prescribed test procedures.
Accordingly, the ARB reserves the right to conduct additional emission
tests, in the future, as such tests are developed, that will more adequately
measure emissions from all cycle phases.   If such test results demonstrate
that the Dinan Supercharger System series adversely affect emissions during
off—cycle conditions (defined as those conditions which are beyond the
parameters of the Cold—Start CVS—75 Federal Test Procedure), this Executive
Order shall be effectively rescinded as of the date the test results are
validated. Further, if such test results or other evidence provides the ARB
with reason to suspect that the Dinan Supercharger System series will affect
the durability of the emission control system, Dinan shall be required to
submit durability data to show that the durability of the vehicle emission
control system is not, in fact, affected and/or that the add—on or modified
part demonstrates adequate durability.

In addition to the foregoing, the ARB reserves the right in the future to
review this Executive Order and the exemption provided herein to assure that
the exempted add—on or modified part continues to meet the standards and
procedures of Title 13, California Code of Regulations, Section 2222, et
seq.                                                           .
THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF ANY
CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED
BENEFITS OF DINAN ENGINEERING‘S DINAN SUPERCHARGER SYSTEM.

No claim of any kind, such as "Approved by the Air Resources Board" may be
made with respect to the action taken herein in any advertising or other
oral or written communication.

Violation of any of the above conditions shall be grounds for revocation of
this order. The order may be revoked only after ten day written notice of
intention to revoke the order, in which period the holder of the order may
request in writing a hearing to contest the proposed revocation.  If a
hearing is requested, it shall be held within ten days of receipt of the
request and the order may not be revoked until a determination after hearing
that grounds for revocation exist.             :

Executed at El Monte, California, this /{f/   da    of May 1996.

I.     INTRODUCTION
       Dinan Engineering of 150 S. Whismah, Building "E", Mountain View,

California 94041 has applied for an exemption from the prohibitions in Section

27156 of the California Vehicle Code (VC) for the Dinan Supercharger System

designed for 1994/95 BMW 530T, 5301 & 5401, 1993—95 BMW 7401 & 8401.
II.    CONCLUSIONS
       Based on emissions testing of the Dinan Supercharger System on a 1995

BMW 5401, the staff concludes that the Dinan SuperchargerASystem will not

adversely affect exhaust emission from vehicles for which the exemption is

requested.

III.   RECOMMENDATION
       The staff recommends that Dinan Engineering be granted an exemption for

their Dinan Supercharger System for installation on 1994/95 BMW 530T, 5301 &

5401, 1993—95 BMW 7401 & 840i.    The staff also recommends that Executive Order

D—176—9 be issued.

IV.    SUPERCHARGER_DESCRIPTION
       The Dinan Supercharger System is specifically designed for installation

on —1994/95 BMW 530T, 530i & 5401i, 1993—95 BMW 740i & 840i.    The supercharger is
designed to increase the volumetric efficiency of the BMW enginé by forcing

more air into the engine than it would normally consume in a non—supercharged

condition.   Air is delivered to the supercharger from a replacement K & N

filter which is supplied by Dinan with their supercharger kit.      The

installation of the superéharger is designed to be self contained, using no 011

feed lines to lubricate the bearings of the supercharger.      The boost is
                                       ~1—


}imited to 5.5 psi., no wastegate is utilized to limit boost..    Installation of

the supercharger requires modifications to be made to the factory fuel

injection system and emission control system certified with the stock engine.

         The Dinan supercharéer is a centrifugal air compressor mounted and

powered similar to an automotive air conditioning compressor.     The air

compression operation is achieved by rotating the impeller wheel within the

compressor housing.    Rotational energy is transferred from the engine‘s

crankshaft to the supercharger‘s input shaft by a belt and pulley system.          The

rotational speed of the supercharger‘s input shaft is increased with respect to

the crankshaft.    The supercharger‘s internal belt drive system increases the

impeller‘s rotational speed relative to the rotational speed of the input

shaft.    Air is supplied from an aftermarket air filtration system to the

supercharger, the supercharger then discharges the pressurized air into

a replacement ducting that is connected to the OEM throttle body.

         Modifications to the emissions control system that are involved with the

installation of the supercharger are as listed:   The relocation of the

crankcase breather hose, new fuel injectors, new PROM chip, relocation of the

pop—off vailve, and a modification to the air flow meter bridge circuit.      In the

OEM configuration, the crankease breather hose is plumbed into the air intake

system between the air filtration assembly and the intake manifold — usually on

or near the throttle body.   The addition of the supercharger would pressurize

the intake tract, eliminating the necessary vacuum at the OEM location.        '

Therefore, according to the manufacturer, the crankcase breather outlet is

relocated upstream of the supercharger where the vacuum condftion exists to

ensure the breather continues to perform its original function.     The

recalibrated replacement PROM is designed to take advantage of the
                                       —2~


supercharger‘s boost condition, fuel and timing tables in the modified

replacement PROM are altered to handle the change from a naturally aspirated

condition to a supercharged condition.     No changes are made to the timing and

fuel tables that are active during close loop operations.        The factory fuel

injectors, Lucas, model # 5207002, with a maximum flow rate of 18.13 1b./Hr.

are replaced with a Lucas, model # 5207009, with a maximum flow rate of 28.8

Tb./Kr.     This change provides for the greater flow of fuel needed during high

boost.     The pop—off valve is designed to close the PCV circuit at high intake

manifold vacuum, with the installation of the supercharger and the relocation
of the PCV, the pop—off valve is not needed.     The addition of the resistor

circuit is designed to rescale the air flow meter to meet the demands of higher

air flow passed by the supercharger.

          Dinan‘supplies all the necessary brackets, hoses, ducting, hardware, and

installation instructions.

V.        DISCUSSION OF THE SUPERCHARGER
          A 1995 BMW 540i with a 4.0L V8 engine was used for the evaluation of the

Dinan Supercharger System.     The dynamometer inertia weight and horsepower

settings were 4000—lbs and 7.2—hp respectively.        The emission tests conducted

by Clean Air Vehicle Technology Center of Hayward, California, for Dinan

Engingering, consisted of one Cold Start CVS—75 emission test in the modified

configuration (Dinan Supercharger System installed).       The ARB did not perform

emissions testing to confirm the test results submitted by the applicant.           A

summary of the test results is shown below:

                           Exhaust Emission Test Results

Test                          Exhaust Emissions (gm/mi)

Mode                         NMHC                cCO                 NOx
Device w/dfs                 0.21               2.84                 0.12

Standards                    0.25               3.4                  0.4


       The CVS—75 emission test results at Clean Air Vehicle Technology Center

indicates the vehicle is below the applicable emissioļ¬s standards set for that

engine family.   Therefore, based on the test results, the staff concludes that

the installation of the Dinan Supercharger System will not have an adverse

effect on exhaust emissions of the affected vehicles.

       Dinan Engineering has submitted all the required {nformation and

fulfilled the requirements for an exemption.
