http://www.pistonheads.com/news/defa...?storyId=16061 The web is alive at the moment with technical details of the new M3 V8 engine, and we know many of you already have much of the details. If you don't, this is the full set of information released by BMW. To hear the engine being worked hard, click on the links below to hear what our man came back from BMW with... Sound file 1 (MP3) Test bed 0-200km/H Sound file 2 (MP3) Nurburgring The key details are: * 3999cc * 414bhp @ 8,300rpm * 295lb ft @ 3,900rpm (251lb ft available from 2,000rpm) * 8,400 max engine speed * Engine weighs 202kg – 15kg lighter than old ‘six’ * Aluminium silicon alloy crankcase, iron-coated pistons run directly in the bores of hard silicon crystals * Bedplate structure * Crankshaft weighs 20kg – 5 main bearings * Oil cooled pistons * High-strength steel magnesium alloy connecting rods weighing 623g each * Single piece alloy cylinder heads with 4 valves per cylinder * Double Vanos variable camshaft control * Double chain-driven cams * Oil system works to 1.4G with 2 pumps * 8 individual throttle bodies. Accelerator pedal position monitored 200 times per second.
