Pursuant to the authority vested in the undersigned by Sections 39515 and
39516 of the Health and Safety Code and Executive Order G—45—5;

IT IS ORDERED AND RESOLVED: That the installation of the turbocharger
kit number 3—0000W1 manufactured by BAE, of 3032 Kashiwa Street,
Torrance, California 90505, has been found not to reduce the
effectiveness of required motor vehicle poliution control devices and,
therefore, is exempt from the prohibitions of Section 27156 of the

having a 195.9 cubic inch displacement six—cylinder engine.

This Executive Order is valid provided that installation instructions for
this device will not recommend tuning the vehicle to specifications
different from those submitted by the device manufacturer.

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

Marketing of this device using an 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 Air Resources Board.  Exemption of a
kit shall not be construed as an exemption to sell, offer for sale, or
advertise any component of a kit as an individual device.

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.


No claim of any kind, such as "Approved by Air Resources Board", may be
made with respect to the action taken herein in any advertising or other
oral or written communication.

                                  Staff Report

                                 October 7, 1981

                     Evaluation of the BAE Turbocharger Kit
                    No. 3—0000W1 for Compliance with the
             Requirements of Section 27156 of the Vehicle Code


      BAE, of 3032 Kashiwa Street, Torrance, California       90505, has

applied for exemption of a turbocharger kit from the prohibitions of

Section 27156 of the Vehicle Code (V.C.).        The kit, turbocharger kit

number 3—0000W1, is intended for 1980 and 1981 model—year BMW 6331 and

733i models having a 195.9 cubic inch displacement (CID) six—cylinder

gasoline engine.

      BAE has submitted comparative emissions data from back—to—back

cold—start CVS—75 and hot—start HFET tests on a 1981 BMW 633i model with

5—speed manual transmission conducted at Olson Engineering, Inc., in

Huntington Beach, California.

      Confirmatory tests were conducted on the same vehicle at the Air

Resources Board (ARB) laboratory in El Monte, California.

      The purpose of turbocharging is to increase the volumetric

efficiency of an engine by forcing more air into an engine than it would

take in under naturally aspirated conditions.

      The major components of the BAE turbocharger kit number 3—0000W1 are

a turbocharger (Rajay Model No. 300E or Airesearch Model No. TAOQ4 H3), a

replacement BAE exhaust manifold, a pressure control wastegate, a fuel

enrichment control, and a boost pressure controlled fuel regulator.        The

components are packaged with installation hardware and installation

instructions and sold as a kit.

        The original equipment manufacturer (OEM) exhaust manifold is

replaced by a BAE manifold.     The turbine inlet mounts directly to the

replacement manifold.     The turbine, driven by exhaust gases, is linked to

the compressor by a solid shaft.     Intake air from the air box, of the

L—Jectronic fuel injection system, is routed to the compressor.

Compressed air is then piped to the intake plenum through the discharge


        The lubrication of the turbocharger is provided by a steel—braided

line from the oil filter adapter located at the engine block to the

turbocharger bearing housing.     Oil from the turbocharger is returned to

the engine block.

        Maximum positive manifold pressure (boost) is limited to 7 psig by a

wastegate mounted on the exhaust manifold.     The wastegate is preset to

dump excess exhaust gases when intake manifold pressure reaches 7 psig.

        The kit also contains a fuel enrichment control.   The control has a

vacuum line which tees to the left side of the intake plenum for sensing

positive boost conditions.     Also attached to the control are three sets
of wire which lTink to the oxygen sensor, temperature sensor, and

throttle valve switch.     When 2 psig is sensed by the control, the

throttle valve opens allowing more intake air and fuel into the

combustion chamber.     Upon sensing 3.5 psig of boost pressure, the oxygen

and temperature sensors are deactivated to signal the computer (in the

car) to run in the rich mode as in cold—start/warm—up conditions.

      Additional fuel enrichment is provided by the BAE boost pressure

 controlled fuel regulator during high boost pressures.     The regulator is

 positioned in the fuel return line between the OEM fuel pressure

. regulator and the fuel tank.    During high boost conditions, the BAE

 regulator blocks the return line and increases the pressure differential

 across the injectors, thus forcing more fuel to be injected.

      A vacuum delay valve is used to control NOx emissions and to

 suppress detonation.    The valve is installed in the vacuum line prior to

 the vacuum return mechanism of the distributor.

      No modifications to the OEM tune—up specifications are required when

 the turbocharger kit is installed.     All OEM emission controls are left


      BAE recommends that premium non—leaded fuel be used with the

 turbocharger kit, but regular non—leaded fuel is compatible.


      A 1981 BMW 633i mode?! with a six—cylinder engine and 5—speed manual

 transmission was used for testing.    The certification test weight is

 3875 lbs.     The road load horsepower (RLHP) used in the testing was 12.6

 horsepowér at 50 mph.

      Testing at the ARB laboratory consisted of cold—start CVS—75 and

hot—start HFET tests at normal RLHP to determine exhaust emissions of the

unmodified (baseline) and turbocharged (device) configurations for



       The applicant‘s and ARB‘s emissions test data are shown in Table 1

and Table 2, respectively:

       The two sets of CVS—75 and HFET comparative emissions tests show

that the turbocharger kit, when installed, will not adversely affect the

vehicle‘s exhaust emissions.


       Comparative emissions tests indicate that the BAE turbocharger kit

number 3—0000W1 will not adversely affect exhaust emissions when

installed in accordance with the manufacturer‘s instructions.    The staff

recommends that BAE be granted an exemption from the prohibitions of

¥.C.    Section 27156 for this kit for 1980 and 1981 model—years BMW 633i

and 7331 models having a 195.9 CID six—cylinder engine.    The staff

recommends that Executive Order No. D—97—7 be adopted.
