                                  SUMMARY


       The Turbo Shop, Inc. (Turbo Shop) has applied for an update to

Executive Order D—180—4 which exempts their air—to—air intercooler Kit

from the prohibitions of Vehicle Code Section 27156.    The existing exemption

applies to 1983—1987 model year Ford Motor Company vehicles powered by a

6.91 Navistar International heavy—duty diesel engine and 1988—1990 model

year Ford Motor Company vehicles powered by a 7.3L Navistar International

heavy—duty diesel engine.   The update is requested to include the 1991

model—year Ford Motor Company vehicles powered by a 7.3L Navistar

International heavy—duty diesel engine.

       Because Turbo Shop, Inc. was granted an exemption for 1988—1990 model

year 7.3L Navistar International heavy—duty diesel vehicles and the 1991

model year 7.3L heavy—duty diesel engine is a carry—over from the previous

model years, the staff concludes that Turbo Shop, Inc.‘s add—on air—to—air

intercooler kit will not have an adverse effect on exhaust emissions from

vehicles for which the exemption update has been requested.

       The staff recommends The Turbo Shop, Inc. be granted an update as

requested and that Executive Order D—180—8 be issued.


EVALUATION OF THE TURBO SHOP, INC.‘S ADD—ON AIR—TO—AIR INTERCOOLER KIT FOR
EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE
    WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS.




I.     INTRODUCTION

       The Turbo Shop, Inc. (Turbo Shop) of 940 West Manchester, Inglewood,

CA 90301, has applied for an update to Executive Order D—180—4, which

exempts their air—to—air intercooler kit model from the prohibitions in

Vehicle Code Section 27156.   The exemption applies to 1983—1987 model year

Ford Motor Company vehicles powered by a 6.9L Navistar International heavy—

duty diesel engine and 1988—1990 model year Ford Motor Company vehicles

powered by a 7.31 Navistar International heavy—duty diesel engine.   The

update is requested to include the 1991 mode]l year Ford Motor Company

vehicles powered by a 7.3L Navistar International heavy—duty diesel engine.

II.    CONCLUSION

       Based on the following: (1) an exemption has been granted for the

installation of the Turbo Shop‘ s air—to—air intercooler system on 1988—1990

model year 7.3L Navistar International heavy—duty diesel vehicles; (2) the

1991 mode?! year 7.3L heavy—duty diesel engine is a carry—over from previous

model years; (3) previous comparative tests evaluating emission effects of

several add—on intercooler systems and the staff‘s technical evaluation of

the intercooler‘s impact on exhaust emissions, the staff concludes that

Turbo Shop‘s add—on air—to—air intercooler kit will not adversely affect

exhaust emissions from vehicles for which the exemption update is requested.

III.   RECOMMENDATIONS

       The staff recommends that The Turbo Shop be granted an update as

requested and that Executive Order D—180—8 be issued.


IV.    INTERCOOLER_KITDESCRIPTION
       The purpose of the Turbo Shop intercooler system is to reduce the

temperature of the intake air that is charged into the turbocharged engine.

A reduction in the intake air temperature allows a greater charge density

(more mass of air flowing through the engine) to enter the combustion

chamber.   This means more fuel into the engine at any given manifold

pressure and, therefore, more power output from the engine.    Also, the

reduction in the intake charge temperature results in lower

combustion/exhaust temperature.

       The major components of the system include an air—to—air heat

exchanger and inter—connecting bent tubes.    The compressed air from the

turbocharger enters through one section of the heat exchanger and ambient

air, as a cooling medium, flows through the other section, cooling the

heated compressed charge air.     The cooled compressed air then passes out of

the heat exchanger to the throttle(s) for induction to the engine.      A

pressure drop occurs when the compressed air passes through the heat

exchanger which varies depending on the size of the heat exchanger, the

temperature of the cooling medium {ambient air) and the available flow rate

of the cooling medium.

       The inlet and outlet pipes of the Turbo Shop‘s air—to—air intercooler

system are made from 2—1/4" and 2—1/2" steel tubing, respectfully.      The

length of the tubing varies according to the model—year of the engine.        No

emission control components are removed, disconnected or relocated when the

air—to—air intercooler kit is installed.


 v.    DISCUSSION
       Turbo Shop‘s add—on air—to—air intercooler kit model is designed for

installation on 1983—1987 model year Ford Motor Company vehicles powered by

a 6.9L Navistar International heavy—duty diesel engine and 1988—1991 model

year Ford Motor Company vehicles powered by a 7.3L Navistar International

heavy—duty diesel engine.   The applicant claims that no modifications to the

kit is necessary for the installation on 1991 mode] year applicable

vehicles.   According to performance analysis previously submitted by other

manufacturers seeking exemption, the thermal efficiency of the intercooler

system ranges between 40 percent to 84 percent.

       Based on predicted efficiency of a heat exchanger and a review of the

intercooler system, the staff believes that the Turbo Shop‘s add—on air—to—

air intercooler kit will not adversely affect a turbocharged vehicle‘s

emissions or degrade a vehicle‘s driveability.

for which the exemption update is requested.

III.   RECOMMENDAT

       The staff recommends that The Turbo Shop be granted an update as

requested and that Executive Order D—180—9 be issued.


IV.    INTERCO     K            PTIO

       The purpose of the Turbo Shop intercooler system is to reduce the

temperature of the intake air that is charged into the turbocharged engine.

A reduction in the intake air temperature allows a greater charge density

(more mass of air flowing through the engine) to enter the combustion

chamber.   This means more fuel into the engine at any given manifold

pressure and, therefore, more power output from the engine.     Also, the

reduction in the intake charge temperature results in lower

combustion/exhaust temperature.

       The major components of the system include an air—to—air heat

exchanger and inter—connecting bent tubes.     The compressed air from the

turbocharger enters through one section of the heat exchanger and ambient

air, as a cooling medium, flows through the other section, cooling the

heated compressed charge air.     The cooled compressed air then passes out of

the heat exchanger to the throttle(s) for induction to the engine.       A

pressure drop occurs when the compressed air passes through the heat

exchanger which varies depending on the size of the heat exchanger, the

temperature of the cooling medium (ambient air) and the available flow rate

of the cooling medium.

       The inlet and.outlet pipes of the Turbo Shop‘s air—to—air intercooler

system are made from steel tubing.     The length of the tubing varies

according to the model—year of the engine.    No emission control components

are removed, disconnected or relocated when the air—to—air intercooler kit

is installed.


     v.    DISCUSSION

©          Turbo Shop‘s add—on air—to—air intercooler kit model is designed for

    installation on 1989—1991 model year Dodge vehicles powered by a 1990 5.91

    Cummins 6BT heavy—duty diesel engine with a manufacturer production date of

    February 1, 1991 or earlier.   The applicant claims that no modifications to

    the kit are necessary for the installation on 1991 model year applicable

    vehicles.   Dodge vehicles manufactured after February 1, 1991 will not be

    equipped with the Cummins 687 engine.   The 1991 model year Cummins heavy—

    duty diesel engine has a new model number and comes equipped with an

    intercooler system.

           According to performance analysis previously submitted by other

    manufacturers seeking exemption, the thermal efficiency of the intercooler

    system ranges between 40 percent to 84 percent.   Based on predicted

    efficiency of a heat exchanger and a review of the intercooler system, the

    staff believes that the Turbo Shop‘s add—on air—to—air intercooler kit will

    not adversely affect a turbocharged vehicle‘s emissions or degrade a

    vehicle‘s driveability.
