For those seeking the ultimate high performance driving experience, Dinan has once again redefined M5 and M6 performance with a bored and stroked 5.7 liter version of BMW’s V-10 engine. The engine produces over 600 horsepower along with stump-pulling torque that exceeds 400 lb-ft from just 3000 rpm right to the rev-limit at 8100 rpm. As incredible as BMW’s V-10 is in stock form, just imagine the acceleration that results from an additional 126 horsepower @ 5800 rpm and 116 lb-ft torque @ 5600 rpm*! Equally impressive is the fact that all of this performance is available without sacrificing BMW-like drivability or the peace of mind that comes from matching new car warranty coverage for up to 4 years or 50,000 miles. Dinan’s 29 years of BMW tuning and racing experience ensure that the engines will not only perform but also provide years of trouble free driving excitement. Much of the technology that has made Dinan’s Grand-Am Daytona Prototype engines both competitive and reliable has carried over to the 5.7 Liter V-10 engine program for the street, ensuring that the engines produce incredible power along with race-proven durability. Each engine is dyno-tested prior to shipment, verifying power output in the same rigorous manner employed for the Daytona Prototype racing engines. The engine is supplied as an assembled long-block, fully prepared to directly replace the stock engine without modification. Maximum performance is achieved when the engine is equipped with the optional High Flow Air Mass Meter Assemblies, High Flow Throttle Bodies and Free Flow Mufflers, producing an incredible 611 hp @ 7500 rpm and 468 lb-ft torque @ 6000 rpm. For those seeking ultimate performance from their M5 or M6, without sacrificing civility, reliability or warranty coverage, the Dinan 5.7 Liter V-10 is the definitive solution.
