After reading and listing to the thread thet Ryan started regarding the AutoUnion racers, it brought back the memory of the BRM V-16. A engine boasting 1.6 liters, 32 valves and 600 bhp @ 12,000 RPM! Thats 340.6 bhp per liter! Known more for it's ferrocious sound that had the reputation for being so loud that other drivers would not drive along side of it than it's success (or failure as it may be). But it was an awsomely powerfull engine. Here a some sound clips from Goodwood. Enjoy! http://gpl.krej.cz/mp3.html
