These videos show "Mavis," a Bentley 8-Litre chassis powered by a 1,500-hp, 42-liter Packard V-12 engine from a WW II PT boat. Incredible sound and presence! The first video came to my attention via Road & Track magazine.
Here she is at speed and belching fire on return to the pits. Love how it looks just like a 1920s/30s land speed record car!
