For those seeking the ultimate high performance driving experience, Dinan has once again redefined M3 performance with a bored and stroked 4.6 liter version of BMW's V-8 engine. The engine produces 502 horsepower along with increased torque of 384 lb-ft at 5600 rpm. As incredible as BMW's V-8 is in stock form, just imagine the acceleration that results from a maximum gain of 105 horsepower @ 6400 rpm and a maximum gain of 96 lb-ft torque @ 5000 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. If your vehicle is no longer under the BMW factory warranty, we will cover you new engine for 2 years and unlimited miles.
Dinan's 35 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 4.6 Liter V-8 engine program for the street, ensuring that the engines produce incredible power along with race-proven durability.
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 Intake , High Flow Throttle Bodies, 16% underdrive pulley and Free Flow Mufflers, producing an incredible 502 peak hp @ 7500-7800 rpm and 384 lb-ft of peak torque @ 5000 rpm.
