      EVALUATION OF GALE BANKS ENGINEERING‘S$ POWER PACK SYSTEM FOR EXEMPTION
         FROM THE PROHIBITIONS OF VEKICLE CODE SECTION 27156 IN ACCORDANCE
        WITH SECTION 2323, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS

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 Power Pack System designed for 1989—92 model—

year motorhomes with a gross vehicle weight (GYVW) of 14,000 lbs. or greater

powered by a 7.5 liter Ford EFI gasoline engine on either a Ford or Oshkosh

chassis.

        Banks has submitted a completed application and all the required

information as well as comparative temperature test data.

II.     CONCLUSION

        Based on the submitted information and the temperature test data

performed on a 1990 7.5 liter gasoline—powered motorhome (GVW greater than

14,000), the staff concludes that the installation of the Banks‘ Power Pack

System will not adversely affect the emissions on the applicable 1989—92

motorhomes .

III. RECOMMENDATIONS

        The staff recommends that Banks be granted Executive Order D—161—27 for

use of the Power Pack System on 1989—92 model—year motorhomes with a gross

vehicle weight (GYVW) of 14,000 1bs. or gréater powered by a 7.5 liter Ford

EFI gasoline engine on either a Ford or Oshkosh chassis.

IV.     DESCRIPTION

        The purpose of the Banks Power Pack System is to enhance the engine‘s

power and fuel efficiency through the reduction of restrictions in the

intake and exhaust system.      The Power Pack System consists of exhaust

                                         —~1—


manifolds, pre—catalyst piping, and ram air inductor.

      The exhaust system consists of tubular exhaust manifolds "headers"

constructed out of #14 gage steel, ¥—pipe assembly, low restriction muffler,

and a low restriction tail pipe.    As with the original equipment

manufacturer‘s (OEM) exhaust system, the main function of the Banks Power

Pack System is to route exhaust gases from the two exhaust manifolds of the

engine into the catalytic converter prior to the muffler.    Each cylinder has
a 1.5" diameter tube that combines with the adjacent tubes into a 2.5"

diameter connector.    On each side of the engine, these two 2.5" connectors

feed directly into the ¥—pipe where they cutput as one pipe into the

catalytic converter.     The Banks‘ ¥—pipe houses the oxygen sensor similar to

the OEM.     The Power Pack System also includes an air inductor, which uses a

flex hose and a boot type funnel located at the grill to naturally induce

lower temperature intake air.     Installation of the Banks Power Pack System

does not alter the OEM location of the catalyst, oxygen sensor, or air

injection.

V¥.   POWER PACK SYSTEM EVALUATION AND DISCUSSION

      New vehicle certification of Ford powered motorhomes that Banks has

requested exemption on required the use of an engine dynamometer due to

their weight classification.     Since Banks sells only a small volume of Power

Pack systems applicable to this application and the cost of testing on an

engine dynamometer is prohibitive, Banks requested that an exemption be

granted based on data from temperature testing instead of engine emission

testing which was accepted by the ARB for their exemption of heavy—duty

motorhomes powered by General Motors engines.

      A 1990 Starcraft Motorhome powered by a Ford 7.5 liter EFI engine was
                                       _2.


used as the test vehicle.     Testing consisted of sampling the catalyst inlet

exhaust temperature at various engine RPMs in the baseline and modified

configuration.    ARB staff reviewed the setup, checked the calibration, and

observed the testing during baseline and modified temperature data

acquisition.     Results are listed in Table 1.

3500           1463               1383              —80              —5.5%

3000           1450               1401              —49              —3.4%

2700           1411               1383              —28               —2.0%


       The Power Pack temperature test data and the stock temperature test

data submitted by the applicant varied no greater than 5.5 percent in

exhaust temperature.     Furthermore, a decrease in temperature of this

percentage will not have any additional impact on catalyst deterioration.

Based on these results, the staff concludes that the installation of the

Banks Power Pack System will not have an adverse effect on the exhaust

emissions of the affected vehicles.      The Gale Banks Engingering submitted

all the required information and fulfilled the requirements for exemption.

      ratties.   Re—tighten clamps or reposition tubing slightly if
      necessary to eliminate leakts and rattles.

      NOTE: The exhaust sysfem.will smoke upon initial start up. This is
      because grease used in the tube bending process will burn off the
      ~inside of the tublng as it warms up.
