                            EXECUTIVE ORDER D—455—24

                      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 Califomnia Vehicle Code for the Honda Motor Corporation vehicle applications
listed in Exhibit A, excluding any vehicle certified to Low Emission Vehicle II Super Uitra
Low Emission Vehicle (LEV II SULEV) or lower emission standards.

The Comptech Supercharger includes the following main components: NOVI 1000R
supercharger ($2000 vehicle model), Whipple 1600A supercharger (NSX vehicle model),

Eaton MP62 supercharger (all other vehicle models in Exhibit A), Comptech air intake box
{$2000 only), intake manifold (NSX only), Walbro fuel pump ($2000 only), and Comptech fuel
pressure regulator. For some vehicle models, the stock fuel pressure regulators are replaced
with higher—pressure Comptech regulators. Others utilize an add—on electronic timing calibrator
or reprogramming of the stock controller. Several models‘ stock air intake boxes are replaced
with the kit‘s smaller intake box in order to accommodate the supercharger. The V—6 NSX and
most 4—cylinder vehicle models‘ stock intake manifolds are replaced with the combination
supercharger and intake manifold assembly. Some models also utilize a MAP sensor
electronic signal modifier that prevents excessive voltage signal when under boost conditions.
This also replaces traditional vacuum hose bypass systems. 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, the $2000 2.2L engine uses a 4.5" diameter
pulley, and the $2000 2.0L engine uses a 4.7" diameter pulley. All other vehicle models utilize
either a 3.6" or 3.8" diameter pulley. Maximum boost for all models is limited to 6 psi.



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 2005 model year Honda Motor Company Acura TL vehicle (Test Group
5HNXVO3.24B4) certified to the Low Emission Vehicle II Ultra Low Emission Vehicle (LEV 1!
ULEV) and Supplemental Federal Test Procedure (SFTP) standards:

Federal Test Procedure:

Test results showed that the Comptech Supercharger when installed on the vehicle did not
cause exhaust emissions to exceed the applicable emission standards during the Cold Start
CVS—75 Federal Test Procedure or SFTP cycles. This Executive Order is also based on the
On—Board Diagnostic |I (OBD I1) testing conducted on the same test vehicle. Comptech



Supercharger when installed on the test vehicle did not affect the vehicle‘s ability to perform its
OBD I1 monitoring.

In addition, the ARB reserves the right in the future to review this Executive Order and the
exemptiqn 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     /5 f day of August 2005.
