Evaluation of the Turbo International Turbocharger Kit for Compliance
With the Requirements of Section 27156 of the Vehicle Code



I.    INTRODUCTION

      Turbo International of 12272 Monarch Street, Garden Grove, California

92641 has applied for exemption of a turbocharger kit from the prohibitions

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

model number 301—E, is intended for 1981 and older model year gasoline

powered motor vehicles having a Chevrolet 305 or 350 CID eight—cylinder

engine and automatic transmission.

      Turbo International has submitted back—to—back emissions tests
conducted on a 1981 Chevrolet Corvette at Custom Engineering Performance

in Garden Grove, California.    Confirmatory tests were conducted on the

same vehicle at the Air Resources Board (ARB) laboratory in El Monte,

California.

II.   TURBOCHARGER KIT DESCRIPTION

      The purpose of the turbocharger kit is to increase the volumetric

efficiency of an engine.   The major components of the Turbo International

kit are a Rayjay turbocharger, a replacement exhaust manifold {right

bank), a crossover pipe, a carburetor—to—manifold adapter box, and a

watgr injection system.    The components are packaged with installation

hardware and instructions and sold as a kit.


    The crossover pipe routes the exhaust from the left cylinder bank to

join the right cylinder bank exhaust.     The Turbo International‘s replace—

ment manifold is connected directly to the turbine inlet of the turbocharger.

     Maximum positive manifold pressure is limited to 7 psig by the

size of the compressor inlet.   No wastegate or other active boost

limiting device is used.
     The adapter box is mounted under the carburetor.     The original

carburetor is retained.    No internal modifications are made to the

carburetor.

     Water injection is employed to limit detonation.     Water is piped

from a small plastic reservoir through a solencid to the adapter box.

The solenoid is activated by a signal from a pressure sensor located

on the adapter box at the compressor outlet.     When 1 psig of pressure

is sensed, the solenoid injects water into the adapter box, ahead of

the turbocharger, through a 0.042 inch orifice.     A schematic of the

turbosystem is shown in Figure 1.

III. TEST PROGRAM

     A 1981 Chevrolet Corvette with a 350 CID eight—cylinder engine

and automatic transmission was used for testing.     The certification

test weight is 3625 lbs.    The road load horsepower (RLHP) used in the

testing was 8.0 horsepower at 50 mph.     The following test procedure

was used to determine emissions of the unmodified (baseline) vehicle at

both Custom Engineering and ARB laboratories:

          One cold start CVS—75 at 1 times RLHP

          One hot start HFET at 1 times RLHP

          One cold start CVS—75 at 2 times RLHP

          One hot start HFET at 2 times RLHP

                                     2.


      The test sequence was repeated on the vehicle after the applicant‘s

turbocharger insta11ation.to provide a back—to—back emissions comparison.

*Quality Audit data


VI.    DISCUSSION

       The ARB‘s baseline tests under fiofmai road condition did not yield

any valid data due to instrument problem.    As a result, the 2% quality

audit data was used for comparison with the device test data.

       The 2 sets of laboratory data (Tables 1 and 2) show that there

are some changes in emissions due to the installation of the turbocharger

kit.    The changes, however, are within the test variability and insignificant.

VII. CONCLUSION_AND RECOMMENDATIONS

       Emission tests indicate that the Turbo International turbocharger

kit model 301—E will not significantly effect emissions when installed

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

that Turbo International be granted an exemption from the prohibitions

of V.C. Section 27156 for this kit for 1981 and older model year gasoline—

powered motor vehicles having a Chevrolet 305 or 350 CID eight—cylinder

engine and automatic transmission.    The staff recommends that Executive

Order O—112 be adopted.
