T.P.I.S. FAST—PAK                               (Page 2 of 3)


Marketing of this T.P.1.5. Fast—Pak using an identification other than that
shown in this Executive Order or marketing of this T.P.1.$. Fast—Pak for an
application other than those listed in this Executive Order shall be
prohibited unless prior approval is obtained from the Air Resources Board
(ARB).  Exemption of the T.P.1.5. Fast—Pak shall not be construed as an
exemption to sell, offer for sale, or advertise any component of the kit as
an individual device.

This Executive Order does not constitute any.opinion as to the effect the
use of this T.P.I.S. Fast—Pak may have on any warranty either expressed or
implied by the vehicle manufacturer.

This Executive Order is granted based on a determination that the device
would not show an adverse effect in emissions if tested in accordance with
the Cold—Start CVS—75 Federal Test Procedure. However, the ARB finds that
reasonable grounds exist to believe that use of the T.P.I.S. Fast—Pak may
adversely affect emissions of motor vehicles when operating under conditions
outside the parameters of the previously prescribed test procedures.
Accordingly, the ARB reserves the right to conduct emission tests, in the
future, as such tests are developed, that will more adequately measure
emissions from all cycle phases. If such test results demonstrate that the
T.P.1.S5. Fast—Pak adversely affects emissions during off—cycle conditions
(defined as those conditions which are beyond the parameters of the Cold—
Start CVS—7§ Federal Test Procedure}, this Executive Order shall be
effectively rescinded as of the date the test results are validated.
Further, if such test results or other evidence provides the ARB with reason
to suspect that the T.P.1.$. Fast—Pak will affect the durability of the
emission control system, Tuned Port Inductions Speciaities, Inc. shall be
required to submit durability data to show that the durability of the
vehicle emission control system is not, in fact, affected and/or that the
add—on or modified part demonstrates adequate durability.

In addition to the foregoing, the ARB reserves the right in the future to
review this Executive Order and the exemption provided herein to assure that
the exempted add—on or modified part continues to meet the standards and
procedures of Title 13, California Code of Requlations, section 2222 et seq.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF
CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED
BENEFITS OF THE TUNED PORT INDUCTION SPECIALTIES, INC. T.P.1.S. FAST—PAK.

No claim of any kind , such as "Approved by the Air Resources Board" may be
made with respect to the action taken herein in any advertising or other
oral or written communication.

        I.        INTRODUCTION
                  Tuned Port Induction Specialties, Inc. (TPIS), of 4255 County Road 10

        East, Chaska, MN 55318 has applted for an exemptions from the prohibitions in

        for installation on 1985—91 model—year Camaro/Firebird equipped with a tuned

        port fuel—injected 305/350— CID engine and 1985—91 model—year Corvette.     The

        Fast—Pak includes a throttle body air—foil, adjustable fuel pressure requlator,

        a foam air filter and.a set of spark plugs.

                  P15 has submitted a completed ;pplication and all the required

        information as well as samples of the {ndividual components.



        II.       CONCLUSIONS

                  Based on an engineering evaluation of the operating principles of the

        TPIS‘Fast*?ak, the staff concludes that the installation of the TPIS Fast—Pak

        and its individual components will not»advefse)y affect exhaust emissions, if

        tested in accordance with the Cold—Start CVS—75 Federal Test Procedure, from

        vehicles for which an exemption is requested.



        111.        COM

                  The staff recommends that TPIS be granted exemptions as requested and

        that Executive Orders D—235: D—235—1 and D—235—2 Se issued for the Fast—Pak,

                                                 —1—


P/N‘s 100—111, 100—112, 100—113, 100—114, 100—115 and 100—116, the Throttle

Body Air—Foil, P/N 100—001, and the Adjustable Fue! Pressure Regulator, P/N

100—002, respectively.



IV.     DEVICE DESCRIPTION

        TPIS Fast—Pak consists of the throttle body air—foil, the adjustable

pressure requlator, the foam air filter and a set of spark plug wires,       The

Fast—Pak is designed primarily to enhance vehicle performance through reduced

air flow restriction, improved fuel atomization and increased consistency fn

spark firing.

        A.   Throttle Body Air—Foil

        The throttle body air—foil is designed to create a smoother transition
for the air to travel from the air cleaner assembly hose into the two throttle

body air passages.    Thus, air turbulence is decreased as air passes through the

throttle body air inlet area,     The air—foil has rounded edges and is designed

to fit snuggly into the throttle body air inlet.     The air—foil is approximately

2—1/2 inches long, 1 inch thick with a width varying from 2—1/2 inches to 1/2

inch.

        To ensure that the air—foil remains in place, a half—cylindrical shaped

part, approximately 1 inch in length with a 174 inch radius, has been designed

to fit snuggly into a slot already located in the original equipment

manufacturer (OEM) throttle body.     The air—foil is kept in place by fastening

 it into the half—cylindrical shaped part using a 2—1/4 inch screw.    The

manufacturer claims the installation of the throttle body air foil will cause

 the horsepower to increase by 11.8 HP and the inlet air rate to increase by
                              1


36 CFM.        The installation of the air—foil does not cause the removal of any

emisston control devices nor does it cause the timing parameters to be changed.

Appendix A contains a copy of the installation instructions.

          B.    Adjustable Fuel Pressure Regulator

          The TPIS adjustable fuel pressure regulator is similar to the OEM

pressure regulator except for the addition of an adjusting screw and a metal

disc which is placed on the spring inside the fuel pressure regulator.          Turning

the adjusting screw causes the disc to compress or releage the spring.          The

compression of the spring causes the fuel pressure to be adjusted and optimized

for each vehicle.        The manufacturer claims that as the fuel pressure is raised,

the fuel is atomized better and emissions are reduced.        The adjustable fuel

pressure requlator is installed in the same location as the OEM.        Also,

installation does not cause the rémoval of any emission control equipment nor

changing of the tune—up parameters.        Appendix B contains a copy of the

installation instructions.

          C. ‘Foam Air Filter

          The purpose of the foam air filtercis to allow a less restrictive air

intake.        The foam air filter is a depth style filter directly replacing the OEM

surface style air filter.        Since the dust is trapped throughout the filter‘s

entire thickness, foam air filters have a tremendous capaéity even when air

flow is maintained at a high flow rate.        The foam air filter functions the same

 as the OEM filter and does not cause the removal of any emission control

 devices or change the tune—up parameters.                                                 i
                                                                                          $1
                                                                                          I


          0.     Spark Plugs

          The TPIS spark plugs are designed to replace the OEM spark plugs.       The

manufacturer claims their spark plugs provide radio suppressipn for quiet radio

receptions, less chance of cross—firing and radto quiet for the computer.             The

spark plugs are made of a carbon core wrapped in a fine monel winding.          The

winding is covered with a layer of pure silicon, a nylon webbing and a second

 coat of pure silicon.         The TPIS spark plugs function the same as the OfM and do

 not require removal of any emission control equipment nor'change the tune—up

 parameters.



 v.000    EVALUATION
          An engineering evaluation was conducted to evaluate the impact of the

‘Fast—Pak and its individual components on emissions.         The TPIS spark plugs and

 the foam air filter are both determined‘to be functionally identical to the OENM

 parts.        Installation of these parts do not cause the removal of any emission

  control equipment nor cause changes in the tune—up specifications.         Therefore,

  these parts are considered replacement parts and would not cause the emissions

  to be adversely affected.

           The Fast—Pak afso contains two critical components, the throttle body

  air—foil which changes the air flow and the adjustable fuel pressure
  regulator which adjust the fuel pressure.         TPIS has requested that the Fast—Pak

  and these critical components be exempted for 1985—91 model—year General Motors

  Camaro/Firebird equipped with tuned port fuel—injected 3057350 CID engine and

  1985—91 model—year Corvettes.        Under normal driving conditions, these vehicles

                                                                                            t


are designed to operate in a closed—loop configfiration. which is characterized




                                                                                  meinpagnennemetsemmnercichip inemeemnppatncs
by the Cold—Start CYS—75 Federal Test Procedure driving cycle.    While the

vehicle operates under closed—loop configuration, the on—board computer

monitors the air/fuel mixture to maintain it near a stoichiometric condition.

The on—board computer receives voltage signals from the oxygen sensor and

interprets them as either richer or leaner than a stoichiometric fuel mixture.

Based on the oxygen sensor signal, the on—board computer either increases the

amount of air flow (to lean the mixture) or increases the amount of fuel flow
{to richen the mixture) to maintain the fuel mixture near stoichiometric.

Although the T.f.1.$. Fast—Pak and its components could change the air flow or

the fue! pressure, the on—board computer will compensate and keep the air/fue!l

mixture at stoichiometric levels during closed—loop operations.    Therefore,

T.P.1.S$. Fast—Pak and its components will have no adverse effects on emissions

of the affected vehicles during closed—loop operation.

        However, under open—loop configuration such as quick accelerations, air

and fuel is being supplied by demand and the fuel mixture is not maintained

near stoichiometric.   Although the T.P.I.S. Fast—Pak and its components could

potentially increase emissions during open—loop conditions, the Air Resources

Board (ARB) has not established an official test procedure to evaluate

emissions during open—loop driving conditions.   The ARB, therefore, reserves

the right to conduct emission tests, in the future, as such tests are

developed, that will more adequately measure emissions from all driving cycles.
