                                    SUMMARY



      Gale Banks Engineering (Banks) has applied for exemption from the

prohibitions in Vehicle Code Section 27156 for their add—on turbocharger kit

Model No. 6.2G designed for 1982—1986 Chevrolet/GMC heavy—duty vehicles which

are powered by the General Motors 6.2 liter heavy—duty diesel engine.

      Banks has submitted a completed application and all the required

information as well as comparative exhaust emissions data which shows that

their kit does not have an adverse effect on the emissions from the vehicles

described in the application.   Confirmatory testing performed at the

Raagen—Smit Laboratory verified the applicant‘s test results.

      The staff recommends that Banks be granted an exemption for their add—on

turbocharger kit and that Executive Order D—161—1 be issued.

I.     INTRODUCTION

       Gale Banks Engineering (Banks) of 546 Duggan Avenue, Azusa, California

91702, has applied for exemption from the prohibitions of Vehicle Code Section

27156 for their add—on turbocharger kit Model No. 6.2G6 for 1982—1986

Chevrolet/GMC heavy—duty vehicles powered by the 6.2 liter General Motors

heavy—duty diesel engine.

       Banks has submitted a completed application, all the necessary

information and comparative exhaust emissions data.

II.    CONCLUSION
       Based on the submitted information and the comparative exhaust emissions

tests performed on a 1986 Chevrolet Suburban heavy—duty diesel truck, the

staff concludes that the installation of the Banks turbocharger kit Model

No. 6.26 will not adversely affect exhaust emissions from the vehicles for

which the exemption has been requested.

III.   RECOMMENDATIONS

       The staff recommends that Banks be granted an exemption for this

turbocharger kit for use on 1982—1986 Chevrolet/GMC heavy—duty vehicles

powered by the 6.2 liter General Motors heavy—duty diesel engine and that

Executive Order D—161—1 be issued.

IV.    TURBOCHARGER KIT DESCRIPTION

       The purpose of the Banks turbocharger system is to increase the power

output of the engine by increasing the volumetric efficiency of it by

compressing the intake charge to pressures above that of the atmosphere.     This


increased pressure allows a greater charge density to enter the combustion

chamber providing more oxygen for combustion.      The maximum fuel delivery is

slightly increased in order to maintain proper air—fuel ratios with the

increased air flow from the turbocharger when it is providing positive

manifold pressure (boost}.

       Maximum positive manifold pressure is limited to 10 psig by the size of

the turbine and the compressor.      The maximum engine speed is regulated by the

OEM fuel injection governor which is not modified by the installation of the

kit.   Therefore, by controlling maximum engine speed, maximum turbine speed

and corresponding boost pressures are also controlled.

       No OEM emission controls are removed or disconnected when the

turbocharger kit is installed.

       The major components of the system include a 1.0 A/R ratio Rotomaster

Model No. TO4B turbocharger, custom intake and exhaust tubing, air cleaner

assembly, brackets, hoses and the hardware necessary to complete the

installation.

       Detailed installation instructions are included in every kit to insure

that the turbocharger installation is done properly (see Appendix 1).      A

facsimile of the system identification label is shown in Appendix 2.

¥.     TURBOCHARGER KIT EVALUATION

       Evaluation of the Banks turbocharger kit included analysis of all

submitted information to confirm that it meets the requirements for the

exemption, a comparison of the submitted exhaust emissions data and a

comparison of the confirmatory emissions data generated at the Haagen—Smit

Laboratory.     The test vehicle was a 1986 Chevrolet Suburban heavy—duty diesel

truck with an automatic transmission.


      Banks performed comparative exhaust emissions tests at FCI International

Testing, Inc., in Santa Ana, CA, on the 1986 Chevrolet Suburban described

earlier.   The test program used was the "Test Program for Add—On Turbocharger

Kits for Heavy—Duty Engines" (see Appendix 3).       The results of these tests are

shown in Table 1.

VI.   DISCUSSION

      The steady—state test results indicate that emissions at some test

points were slightly increased, however, the increases are only a few ppm

which are well within the sensitivity limits of the instruments.         This

demonstrates that the addition of the Gale Banks Model 6.26 Turbocharger

kit will not have an adverse effect on emissions from the 1982—1986

Chevrolet/GMC heavy—duty diesel vehicles for which the exemption was

requested.

      Banks has submitted all the required information and fulfilled the

requirements for an exemption.
