                              Relating to Exemptions Under Section 27156
                                           of the Vehicle Code


                                  TOYOTA RACING DEVELOPMENT
                                     6 PSI. 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 6 PSI. Supercharger Kit, manufactured
and marketed by Toyota Racing Development, 335 E. Baker Street, Costa Mesa, California 92626 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 1995—98 T100, 1995—98
Tacoma, and 1996—98 4—Runner that are equipped with a 3.4L engine.

The 6 PSI. Supercharger Kit includes the following main components: Eaton M—62 supercharger, intake
manifold, fuel regulator, and all the necessary hardware needed to connect to the stock air filter housing
and throttle—body using the stock tubing. No changes are made to the stock ignition system. The kit
includes a 2.4" diameter supercharger pulley.                    |

This Executive Order is valid provided that the installation instructions for the supercharger 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 supercharger, as exempt by the Air Resources
Board, which adversely affect the performance of the vehicle‘s pollution control system shall invalidate this
Executive Order.

Marketing of the supercharger using any identification other than that shown in this Executive Order or
marketing of the supercharger 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 supercharger
shall not be construed as 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 the use of the supercharger may have
on any warranty either expressed or implied by the vehicle manufacturer.

This Executive Order is granted based on submitted emissionstest data which showed that the Toyota
Racing Development‘s 6 PSI. Supercharger Kit did not adversely affect tailpipe emissions during the Cold
Start CVS—75 Federal Test Procedure. However, the ARB finds that reasonable grounds exist to believe
that use of the Toyota Racing Development‘s Supercharger Kit 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 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 supercharger will
affect the durability of the emission control systems, Toyota Racing Development 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 assurethat 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 TOYOTA RACING DEVELOPMENT®S SUPERCHARGER KIT.

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 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.

      I. INTRODUCTION

                  Toyota Racing Development of 335 E. Baker Street, Costa Mesa, California 92626 has

      applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for

      their supercharger designed for 1995—98 T100, 1995—98 Tacoma, and 1996—98 4—Runner that are equipped

      With a 3.4L engine.

      II. CONCLUSIONS

                   Based on submitted emissions test data, the staff concludes that Toyota Racing

      Development‘s 6 PSI. Supercharger Kit will not adversely affect exhaust‘emissions from the vehicles for

      which the exemption is requested.

      III. RECOMMENDATION

                   The staff recommends that Toyota Racing Development be granted an exemption for their 6

      PSI. Supercharger Kit for installation on those applicable Toyota vehicies. The staff also recommends that
Le~




      Executive Order D—425—2 be issued.

      IV. SUPERCHARGER KIT DESCRIPTION

                   The 6 PSI. Supercharger Kit has been specifically designed for installation on 1995—98 T100,

      1995—98 Tacoma, and 1996—98 4—Runner that are equipped with a 3.4L engine. The kit operates in

      conjunction with the original equipment manufacturer‘s (OEM) computer controlled fuel injection system

      and emission control system already certified with the stock engine.

                   The purpose of supercharging an engine is to increase its volumetric efficiency and power

      output at particular engine loads and throttle openings. At light engine loads and small throttle openings,

      power output is the same as a normally aspirated engine. At heavy engine loads and increased throttle

      openings, the manifold pressure is increased by the supercharger allowing more air to enter the engine,

      resulting in a hig'her power output. The supercharger is driven utilizing the engine‘s standard serpentine

      belt loop system.


                     The supercharger used for this kit is an Eaton roots type blower, designed to have a maximum

     boost of 6 PSI. Boost is limited only by the diameter of the input pulley.

                     The installation of the kit does not require any major modifications to the stock motor, except

     for the new intake manifold and fuel regulator. The stock air cleaner is utilized with the supercharger

     installation.

     v.              DISCUSSION OF THE SUPERCHARGER KIT

     |               A 1998 Toyota T100 with a 3.4L fuel injected engine certified to a TLEV emission standard

     was used for the evaluation of the supercharger. Testing consisted of one Cold Start CVS—75 Federal Test

     Procedure in the modified configuration, and an OBD II evaluation. Thé dynamometer inertia weight and

     horsepower settings were 4500—lbs and 16.6—hp, respectively. The emissions testing was conducted by the

     Edelbrock Corporation. NMOG and HCHO were calculated following NMOG/NMHC ratio of 1.032 and

     HCHO/NMHC ratio of 0.018 as submitted by Toyota during its new vehicle certification. Table 1.

     list emission results in gm/mi. with the deterioration factors applied.

                                         NMOG            CO _            NOx          HCHO

             Device                      0.16             1.8             0.2         0.003
             Standard                    0.16            4.4              0.7         0.018




                     Results from the emissions test conducted at Edelbrock show the vehicle emissions with the 6

     PSI. Supercharger installed to be within the vehicle‘s emission standards. Based on the test results, the

     staff conclgdes that the installation of the Toyota Racing Development‘s 6 PSI. Supercharger Kit will not

     have an adverse effect on exhaust emissions of the affected vehicles. The ARB did not perform testing to

     confirm the emission test results submified by the applicant; however, ARB staff evaluated the impact of

     the supercharger on the OBD II system. Scan tool testing confirmed that the supercharger did not affect

     the vehicle‘s ability to perform the OBD II system operation. Therefore, based on the test results and


                                                            — 2 —


OBD II evaluation, the staff concludes that the installation of the supercharger will not have an adverse

effect on exhaust emissions on those applicable vehicles when operated similar to the CVS—75 Federal Test

Procedure.

             Toyota Racing Development has submitted all the required information and fulfilled the

requirements for an exemption.
