                                      SUMMARY



       Redline, Inc., a distributor of Italian made Weber carburetors, has

applied for exemption from the prohibitions of Vehicle Code Section 27156 for

the Redline Carburetor Conversion Kit No. K8408 using one (1) Weber model
32/34 DFT carburetor.

       The Redline Carburetor Conversion Kit is designed to replace the Zenith

carburetors found on 1975—1976 Volkswagen Rabbit and Scirocco passenger cars

with 1.5 and 1.6 liter engines.

       Comparative vacuum signal tests and other information submitted

demonstrate that the aftermarket Redline Carburetor Conversion Kit No. K8408

using one (1) Weber model 32/34 DFT carburetor does not adversely affect the

function of the emission control devices of the applicable vehicles.      Based on

the results of the tests and the evaluation of the Redline Carburetor

Conversion Kit, the staff recommends that the exemption be granted as

requested for the following vehicle applications:

MODEL 32/34 DFT WEBER CARBURETOR FOR EXEMPTION FROM THE PROHIBITIONS OF
VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE
CALIFORNIA ADMINISTRATIVE CODE



I.       INTRODUCT I ON

         Redline, Inc. of Compton, California, a subsidiary of Imported Parts and

Accessories Corporation (IMPAC), is a distributor of Italian made Weber

carburetors.      The company has applied for exemption from the prohibitions of

Vehicle Code Section 27156 for a Carburetor Conversion Kit designated as

Redline Kit No. K8408 using one (1) Weber model 32/34 DFT carburetor to

replace the original equipment manufacturer (OEM) Zenith two—barrel

carburetors found on the following vehicles:



      Year      Make              Mode]1     Engine (liter, CID)   Redline Kit No.



1975             Volkswagen   Rabbit, Scirocco        1.5, 90        K8408

1976             Volkswagen   Rabbit, Scirocco        1.6, 97         K8408



         This report describes the evaluation of the Redline Carburetor

Conversion Kit and the findings.

II.      CONCLUSION

         Comparative vacuum signal data and other information submitted by the

applicant demonstrated that the Redline Kit No. K8408 using one (1) 32/34 DFT

Weber carburetor meets the Air Resources Board (ARB) requirements for

exemption from the prohibitions of Vehicle Code Section 27156.


III.    RECOMMENDATION
       Based on the submitted information and the test data on the Redline

Carburetor Conversion Kit, the staff recommends that Redline,   Inc. be granted

exemption from the prohibitions of Vehicle Code Section 27156 for the Redline

Carburetor Conversion Kit No. K8408 for use on the vehicles described above

and that Executive Order No. D—133—9 be issued.

IV.    DEVICE DESCRIPTION

       The Redline Carburetor Conversion Kit No. K8408 uses one (1}) model 32/34

DFT Weber carburetor as an economical replacement for the OEM carburetors

found on the 1975—76 Volkswagen Rabbit and Scirocco passenger cars described

previously.   These vehicles are equipped with Zenith model 2B2 carburetors

which are of the progressive two—barrel design (See Appendix 1}.

       The Weber 32/34 DFT is a progressive two—barrel carburetor which is

similar in basic design to the OEM carburetors (See Appendix 2).   The Weber

32/34 DFT is a slightly different version of the Weber DFT (Ford 740)

carburetors used as original equipment on some Ford imports orignally sold in

California.   It has provisions for vacuum operated emission control systems,

including distributor vacuum advance/retard units, EGR and air injection

control systems.

       A variety of emission control devices are used on these vehicles.     Some

are integral to the OEM carburetor and others are external devices which

either control specific functions of the OEM carburetor or are activated by

movement of the throttle.   The installation of the Weber carburetor retains

most of these devices or duplicates the functions of the devices in a

different manner.   The 1975 model—year Volkswagens require no modifications,

however, some devices cannot be retained in the 1976 model—year vehicles.      The


following engine coolant temperature controlled valves and the related vacuum

actuating valves are disconnected and plugged after the installation of the

Weber carburetor on 1976 Volkswagen Rabbits and Sciroccos:

       1)     Thermo—time valve for 2nd stage choke pull down vaive

      2)      Coolant temperature valve for accelerator pump check valve

      3)      Coolant temperature valve for cold idle valve

      4)      Coolant temperature valve for 2nd barrel diaphragm valve

      The Redline Kit No. K8408 comes complete with a Weber DFT carburetor, an

air cleaner adaptor, installation instructions (See Attachment 3) and all the

hoses, gaskets and hardware necessary to install the Weber carburetor on the

Volkswagen Rabbit or Scirocco passenger cars.     The carburetor calibration for

kit No. K8408 is shown in Appendix 4.     A facsimile of the identification label

is shown in Appendix 5.

V.    DEVICE EVALUATION
      The applicant performed comparative auxiliary vacuum signal tests at

Import Certification Laboratories in Anaheim, California.     A 1976 Volkswagen

Rabbit with a 1.6 liter engine and a 5—speed manual transmission was used as

the test vehicle.     It would be expected that vehicles of previous model—years

would have the same degree of performance/emissions impact as the vehicle

tested when using the same Redline Kit.     The submitted data are shown in

Appendix 6.

      VI.     DISCUSSION
      The results of the auxiliary vacuum signal tests show no significant

change in vacuum signals for the Weber carburetor compared to the OEM Zenith

carburetor.    Three of the four disconnected and plugged vacuum actuating

valves for the OEM carburetor are for the control of fuel delivery during the


engine warm—up period.   The fourth vaive prevents the second barrel of the

carburetor from opening until after the engine has been warmed up.     The

control of air/fuel ratio during engine warm—up has been designed into the

choke system of the Weber carburetor without the need of any auxiliary

mechanism and the opening of the second barrel is done mechanically through

the accelerator pedal.   The effect on emissions due to the elimination of

these four valves and substitution by a simple choke control during engine

warm—up and mechanical control for the second barrel operation is judged to be

minimal.
      The above demonstrates that the installation of the Redline Kit

No. K8408 and the modifications to the original exhaust emission control

system required for the installation will not have an adverse effect on

emissions from the 1976 Volkswagen Rabbit test vehicle which was selected to

be representative of all the vehicles on this exemption application.     It would

be expected that the conversion kit No. K8408 would achieve the same level of

emission control when installed on the same type of vehicles to replace OEM

carburetors of similar designs.

      Redline has submitted all the required information and fulfilled the

requirements for an exemption.

    All tune—up specifications for the Weber Carburetor remain the same as those specified by the Factory
    for the original unit. Emissions tune—up should be carried out by a suitably qualified Dealer or
    Independent garage, using infrared gas and analyzing equipment.

    NOTE: Late model vehicles fitted with Emission Control Systems have many vacuum lines and
    electrical connections in the fue!l systems. It is essential when dismantling, that disconnected lines
    should be identified with a corresponding number tag or label system. To establish function, locate
    and identify the source of each ling. Use the under hood emissions diagram, or a factory service
    manual for reference when identifying hoses. (Modified vacuum diagrams showing the Weber
    installation are provided in these instructions)

§     All tune—up specifications for the Weber Carburetor remain the same as those. specified by the Factory
    4 for the original unit. Emissions tune—up should be carried out by a suitably qualified Dealer or
      Independent garage, using infrared gas and analyzing equipment.

      NOTE: Late model vehicles fitted with Emission Control Systems have many vacuum lines and
      electrical connections in the fuel systems. it is essential when dismantiing, that disconnected lines
      should be identified with a corresponding number tag or label system. To establish function, focate
      and identify the source of each line. Use the under hood emissions diagram, or a factory service
      manual for reference when identifying hoses. (Modified vacuum diagrams showing the Weber
      installation are provided in these instructions)
