EVALUATION OF DINAN PERFORMANCE ENGINEERING‘S M—CAR STROKER ENGINE FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS 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. Table 1. Stock .

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. .
