ProwlTalk - Prewarcars Man check these out!!! The one car in here is the Napier Railton Special. It was powered by a Napier Lion Engine. This was an aircraft engine designed in the last months of WW1. Get this, this same engine (the actual engine) powered the Napier Railton Special in which John Cobb broke the worlds land speed record of 394 mph in 1938 Then it broke the world water speed record in Malcolm Campbell's "Bluebird" at of 141.7 mph in 1939 and finally powered the Supermarine S-5 seaplane racer at 319 MPH in 1927. The Lion was a 12 cyl, but was in a "w" configuration consisting of 3 banks of 4 cylinders. Designed in 1918, this engine used fuel injection and had 4 valves per cylinder and dual over head cams!!!!!
