                              EXECUTIVE ORDER D—115—12
                       Relating to Exemptions Under Section 27156
                                    of the Vehicle Code

                         HOLLEY PERFORMANCE PRODUCTS
                           THUNDER SUPERCHARGER KIT

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 Thunder Supercharger
kit (p/n 300—520), produced and marketed by Holley Performance Products, 1801
Russellville Road, P.O. Box 10360, Bowling Green, Kentucky 42102, has been found
not to reduce the effectiveness of the applicable vehicle pollution control systems and,
therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for the
1997—2000 Ford F—150 & Expedition, 1997—1998 Ford F—250 Light—Duty, and 1998—1999
Lincolin Navigator vehicles equipped with the 5.4 liter SOHC V8.

The Thunder Supercharger kit includes the following main components: roots
supercharger, intake manifold, boost controlled fuel pressure regulator, air—to—water
intercooler, intercooler pump, throttle body, assorted brackets, tubing, and hardware.
The diameter of the drive pulley is 6.0 inches, and the supercharger pulley diameter is
2.86 inches. Maximum boost is 7.0 psi.

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

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

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

THUNDER SUPERCHARGER KIT                                    (Page 2 of 3)

Marketing of the Thunder Supercharger kit using any identification other than that
shown in this Executive Order or marketing of the Thunder Supercharger kit for an
application other than those listed in this Executive Order shall be prohibited unless
prior approval is obtained from the Air Resources Board.

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

This Executive Order is granted based on emission test results in the modified
configuration using the Cold—Start CVS—75 Federal Test Procedure and examination of
the On—Board Diagnostic II (OBD I1) system. A 2000 Ford F—150 pick—up truck with a
5.4L fuel injected engine (YFMXAO05.4HGC, LEV, MDV2) was used for the evaluation of
the Thunder Supercharger kit. Results from emissions testing conducted at California
Environmental Engineering are shown below (in grams per mile):

                       50k       NMOG — CO                NOx     HCHO
                 Emission Level 0.124    1478             0.257 > 0.0014
                 (w. DF applied)             -
                       STD       0.160 _ 4.4              0.4     0.018

                      120k      NMOG           CO         NOx     HCHO
                 Emission Level 0.163         2.018       0.407   0.0021
                 {(w. DF applied)
                        STD         0.230     6.4         0.6     0.027

The emission test results in the modified configuration were below the applicable
certification standards with the deterioration factors applied. Examination of the OBD 11
system showed the Thunder Supercharger kit does not affect OBD II operation.
Therefore, based on the test results, the staff concludes that the Thunder Supercharger
kit meets the criteria for exempting general criteria parts.

However, the ARB finds that reasonable grounds exist to believe that use of the
Thunder Supercharger kit may adversely affect emissions of motor vehicles when
operating under conditions outside the parameters of the CVS—75 Federal Test
Procedure. 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 Thunder
Supercharger kit adversely affects emissions during off—cycle conditions (defined as
those conditions which are beyond the parameters of the Cold—Start CVS—75 Federal

THUNDER SUPERCHARGER KIT                                   (Page 3 of 3)

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 Thunder Supercharger kit will affect the durability of
the emission control system, Holley Performance Products, 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.


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

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 after
hearing that grounds for revocation exist.
Executed at El Monte, California, this   _/ 7__    da of August 2000.


                                 R. B. Sdmmerfield, Chief
