Dinan strokes the M5/M6's V10 to 5.7-liters, 628 hp
If you have a passion for power and an additional $40,000 in your budget, Dinan can transform your "ordinary" M5/M6 into a race-ready athlete with the heart of the champion. For your 40-large, Dinan will take the 5.0L V10 that powers the "standard" M5/M6 and bore and stroke it to 5.7 liters. The end result is a legitimate road beast that cranks out 628 hp and 482 lb-ft. The additional hp under the bonnet of the Dinan M's still revs freely to 8100 RPM, and much of the torque is available as low as 3000 RPM. To keep Dinan's 5.7L flamethrower breathing freely, the engine tuner added high flow Intake/air mass meter assemblies, high flow throttle bodies, free flow mufflers and a racing exhaust. Sure the extra $40k can almost buy you a spare 335i, but if you want to make your M5/M6 even more exclusive, Dinan's solution is as good as any.
Thanks for the tip, slblack.
