                              EXECUTIVE ORDER D—455—16

                       Relating to Exemptions Under Section 27156
                                    of the Vehicle Code

                                    Comptech Machine
                                  Comptech Supercharger

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 Comptech Supercharger
manufactured and marketed by Comptech Machine of 4717 Golden Foothill Parkway, El
Dorado Hills, CA 95762 has been found not to reduce the effectiveness of required motor
vehicle pollution control devices and, therefore, is exempt from the prohibitions of Section
27156 of the California Vehicle Code for 2003 and earlier Honda Motor Corporation NSX and
$—2000 vehicles, excluding any vehicle certified to Ultra Low Emission Vehicle (ULEV) or
lower emission standards.

The Comptech Supercharger includes the following main components: NOVI 1000
supercharger, Comptech air intake box (S—2000 only), intake manifold (NSX only), Walbro fuel
pump (S—2000 only), and Comptech fuel pressure regulator. For both vehicle models, the
stock fuel pressure regulators are replaced with the higher—pressure Comptech regulator. The
$—2000‘s factory fuel pump is replaced, and the stock air intake box is replaced with the kit‘s
smaller intake box in order to accommodate the supercharger. The NSX‘s stock intake
manifold is replaced with the combination supercharger and intake manifold assembly. The
stock NSX fuel pump is modified with a regulator unit to increase the volitage to it, and the
stock 15 amp fuel pump fuse is replaced with a 20 amp fuse. For 2002 and later models of
both vehicles, an optional controller may be installed in liew of standard mechanical bypasses
and vacuum line modifications. All other emission—related components are in the stock
location relative to the throttle body. The following are the supercharger pulley specifications:
The NSX 3.2L engine uses a 3.8" diameter pulley, the NSX 3.0L engine uses a 4.2" diameter
pulley, and the $—2000 2.0L engine uses a 4.8" diameter pulley. Maximum boost is limited to 6

This Executive Order shall not apply to any Comptech Supercharger advertised, offered for
sale, sold with, or installed on a new motor vehicle prior to or concurrent with transfer to an
ultimate purchaser.

This Executive Orderis valid provided that the installation instructions for the supercharger will
not recommend tuning the vehicle to specifications different from those of the vehicle

Changes made to the design or operating conditions of the device, as exempted by the Air
Resources Board (ARB), that adversely affect the performance of a vehicle‘s pollution control
system shall invalidate this Executive Order.

Marketing of this device using any identification other than that shown in this Executive Order
or marketing of this device for an application other than those listed in this Executive Order
shall be prohibited unless prior approval is obtained from the ARB.

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

This exemption is issued based on submitted emissions test data from an independent
laboratory on a 2000 model—year $—2000 vehicle certified to the Low Emission Vehicle (LEV})

                                                 NMOG          co       NOX      HCHO
Standards (g/mi)                                 0.075        3.4        0.2     0.015
Device (g/mi) with dfs applied                   0.068        0.8        0.1     0.002

Test results showed that the Comptech Supercharger when installed on the vehicle did not
cause tailpipe emissions to exceed the applicable emission standards during the Cold Start
CVS—75 Federal Test Procedure. This Executive Order is also based on the On—Board
Diagnostic II (OBD II) testing conducted on the same test vehicle. Test data showed that the
Comptech Supercharger when instailed on the vehicle did not affect the vehicle‘s ability to
perform its OBD II monitoring.

However, the ARB finds that reasonable grounds exist to believe that use of the      Comptech
Supercharger 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 Comptech Supercharger adversely affects 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 Comptech Supercharger will affect durability
of the emission control systems, Comptech Machine 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 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.


No claims 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 a 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 is made after the hearing that grounds
for revocation exist.

Executed at El Monte, California, this Lli#’l day of November 2002.

                                       AII%fyons, Chief
                                       Mobile Source Operations Division
