I.        INTRODUCTION

          Dinan Performance Engineering (Dinan)-of 81 Pioneer Way, Mountain View,

CA 94041, has applied for an exemptifin from the prohibitions in Section 27156

of the California Vehicle Code (VC) for the M—Car Stroker Engine.        The M—Car

Stroker Engine is designed for installation on 1984 to 1988 BMW MS & M6, and

1991 to 1993 BMW MS5 sports cars equipped w;th a 3.5L gasoline engine.

          Dinan submitted a completed application and other required information,

as well as emissions test data perfogmed at the Milton Roy Company in Orange,

California.

11.       CcoNCLUSTONS
          Based on the submitted information, and emissions testing conducted at

tfie Milton Roy Company and confirmed by the Air Resources Board, the staff

concludes that the Dinan‘s M—Car Stroker Engine will not adversely affect

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


III.      RECOMMENDATION

          The staff recommends that Dinan Performance Engineering, be granted an

exemption for their M—Car Stroker Engine designed for installation on 1984 to

1988 BMW MS & M6, and 1991 to 1993 BMW M5 sports cars equipped with a 3.5L

gasoline engine.         The staff élso recommends that Executive Order D~176—6 be

issued.

IV.       M—CAR STROKER ENGINE DESCRIPTION

          The purpose of the M—Car Stroker Engine package is to increase rear

wheel horse power and torque by altering the design characteristics of the

                                            —1—


crankshaft, pistons, rings, and programmable read'only memory (PROM) chip.

The new crankshaft is designed to provide an additional 6 mm increase in the

stroke of the piston.     Increasing the stroke requires Dinan to install

specially designed forged aluminum pistons with high performance rings.             Table

1 compares the stock engine to the M—Car stroger Engine.as provided by Dinan

Performance Engineering.     Dinan sells the M—Car Stroker Engine package as a

short—block assembly (engine block minus the cylindef heads) with the modified

crankshaft, pistons, and rings already assembled.             Other components in the M—

Car short block assembly are either reconditioned or new OEM parts.             The new

PROM incorporated with the M-Car.package differs from the OEM PROM in ignition

timing and fuel.     The PROM tables are.éltered to compensate for the changes

made to the engine and the recommendation of premium fuel.

         Any additional components which are not part of the original short block

assembly are removed and installed on the Dinan short block assembly using the

supplied gaskets.     No adjustménts are required during the installation.

         V.   DISCUSSION OF THE M—CAR STROKER ENGINE

         Dinan Performance Engineering, has requested that the M—Car Stroker

Engine be exempted for 1984 to 1988 fiMw MS5 & M6, and 1991 to 1993 BMW MS5 sports

cars equipped with a 3.5L gasoline engine.             A 1990 BMW M—5 with a 3.5L engine

                                             ~2~


was used for testing.    Dinan performed testing at the Milton Roy Company with

the vehicle emissions compared against emission standards.                            The inertia weight

was set at 4000 lbs. and 7.7 hp.

        The results of the exhaust emissions test performed at the Milton Roy

Company are shown in Table 2.                              .

        These results show that the emissions of the modified vehicle do not

exceed the vehicle‘s emissions standards.

        Dinan Performance Engineering submitted all of the required information

and fulfilled the requirements for an exemption.
