                              Relating to Exemptions Under Section 27156
                                           of the Vehicle Code

                                  MECHTECH MOTORSPORTS, INC.
                                      5 PSI. TURBO 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 5 PSI. Turbo System, manufactured and
marketed by Mechtech Motorsports, Inc., 1277 Simpson Way, Escondido, California 92029 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 1996/97 BMW vehicles equipped
with a 6 cylinder engine.

The 5 PSI Turbo System includes the following main components: Aerodyne turbocharger, model no.
MT6000, cast iron exhaust manifold with oxygen sensor at collector, new connecting pipes, fuel pressure
regulator located on the fuel return line, intercooler, replacement air inlet box using a K&N style filter,
check valves placed in crankcase breather hoses, and all necessary hardware and tubing for installation.
Manufacturer recommends 92 or higher octane fuel. The turbocharger does not require any auxiliary oil or
water lines for lubrication or cooling.

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

Changes made to the design or operating conditions ofthe turbocharger, 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 turbocharger using any identification other than that shown in this Executive Order or
marketing of the turbocharger for an application other than those listed in this Executive Order shall be
prohibited unless prior approvalis obtained from the Air Resources Board. Exemption of the turbocharger
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 ofthe turbocharger may have
on any warranty either expressed or implied by the vehicle manufacturer.

This Executive Order is granted based on submitted emissions test data which showed that the Mechtech
Motorsports, Inc.‘s 5 PSI. Turbo System 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 Mechtech Motorsports, Inc.‘s Turbo System may adversely affect emissions of motor vehicles when
operating under conditions outside the parameters ofthe previously prescribed test procedures.

5 PSI TURBO SYSTEM                                                (Page 2 of 2)


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 turbocharger 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 turbocharger will affect the
durability of the emission control systems, Mechtech Motorsports, Inc. 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 ofTitle 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 MECHTECH MOTORSPORTS, INC.‘S TURBO 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 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    (/ /day of November 1997.

I. INTRODUCTION

                Mechtech Motorsports, Inc. of 1277 Simpson Way, Escondido, California 92029 has applied

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

turbocharger designed for 1996/97 BMW vehicles equipped with a 6 cylinder engine.

IL CONCLUSIONS

                Based on submitted emissions test data, the staff concludes that Mechtech Motorsports, Inc.‘s

5 PSI Turbo System will not adversely affect exhaust emissions from the vehicles for which the exemption

is requested.

III. RECOMMENDATION

                The staff recommends that Mechtech Motorsports, Inc. be granted an exemption for their

5 PSI. Turbo System for installation on those applicable BMW vehicles. The staff also recommends that

Executive Order D—440 be issued.

IV. TURBO SYSTEM DESCRIPTION

                The 5 PSI. Turbo System has been specifically designed for installation on 1996/97 BMW

vehicles equipped with a 6 cylinder 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 turbocharging an engineis 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 turbocharger allowing more air to enter the engine,

resulting in a higher power output. The turbocharger is drivenutilizing the engine‘s exhaust system.

                The turbocharger used for this kit is an Aerodyne turbocharger, model no. MT66000,

designed to have a maximum boost of 5 PSI. Boost is limited only by the design of the turbocharger.


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

the repiacement of existing manifold with a new cast iron exhaust manifold, new connecting pipes from

the turbocharger to the converter, a fuel pressure regulator located on the fuel return line, addition of an

intercooler, replacement of an air inlet box using a K&N style filter, and addition of check valves placed in

the crankcase breather hoses. As with the stock configuration the oxygen sensoris located at the collector

of the new exhaust manifold. The turbocharger doesvnot require the use of an auxiliary oil or water feed

line for lubrication or cooling.

v.           DISCUSSION OF THE TURBO SYSTEM

             A 1997 BMW Z3 with a 2.8L fuel injected engine was used for the evaluation of the

turbocharger. Testing consisted of one Cold Start CVS—75 Federal Test Procedure in the modified

configuration, and an OBD II evaluation.     The dynamometer inertia weight and horsepower settings were

3125—lbs and 7.6—hp, respectively. The emissions testing was conducted by Environmental Testing

Corporation. Table 1. list emission results in gim/mi.

                                                  Table 1.

                                   NMOG           cCO              NOx

       Standards                   0.125          34               0.4

       Device w/ dfs               0.103          1.89             0.15

             Results from the emission tests conducted at Environmental Testing Corporation show the

vehicle emissions with the 5 PSI. Turbocharger installed to be below the vehicle‘s emission standards with

deterioration factors. Based on the test results, the staff concludes that the installation of the Mechtech

Motorsports, Inc.‘s 5 PSI. Turbo System 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 submitted by the

applicant; however, ARB staff evaluated the impact ofthe turbocharger on the OBD II system. Scan tool

testing confirmed that the turbocharger did not affect the vehicle‘s ability to perform the OBD II system

operation. Therefore, based on the test results and OBD If evaluation, the staff concludes that the


installation of the turbocharger will not have an adverse effect on exhaust emissions on those applicable

vehicles when operated similar to the CVS—75 Federal Test Procedure.

            BMW certified some 2.8 liter engine families in 1996/97 to the Enhanced Evaporative

Emission Standards. The vehicle‘s evaporative emissions should not be affected because the installation of

Mechtech Motorsports, Inc.‘s Turbo System does not modify the vehicle‘s fuel or evaporative emission

control system in a way that would affect its function. Mechtech Motorsports, Inc. has submitted all the

required information and fulfilled the requirements for an exemption.
