I did not get to talk to the owner of the TR6 with the Ford 4 cylinder turbo but he did have a photo showing the car pulling the front wheels off the ground at a drag strip. The 4 cylinder was rated at 400hp but I don't know where the motor came from. I did hear it leave the show though, very impressive. The BSA is a 1939 model from what the owner said. That bike sounded like one of the old oil pumps I remember hearing run in the mountains of Pennsylvania when I was a kid, putt,putt,putt,putt. It is only one cylinder.
