Speed Demon #715 D/BFS

(2009-2014)

Poteet and Main looked like they were going to break the record in 2014 after setting speeds in excess of 460mph in testing, but things went a bit wrong.

The accompanying videos of the 370 mph crash that George Poteet walked away from provide ample testimony to the extraordinary quality of car construction and crew preparation that comprise the Speed Demon operation. At Mike Cook's Bonneville Shootout, everyone rolls as soon as the car passes. Crew and professional emergency vehicles were on top of the crash in less than 15 seconds. Unless you see this first hand it is difficult to comprehend the fine line between record speeds and disaster. George places great confidence in these people and they all delivered.

Speed Demon is powered by a five-litre 2,200 horsepower V8 engine and has won the prestigious Hot Rod Trophy at Bonneville for five straight years. The team is not resting on its laurels however and has stated that it intends to be the first wheel driven car to break the 500mph barrier and exceed the current outright wheel driven record currently held by Don Vesco’s Turbinator. Speed Demon will be back on the Salt next month in an attempt to establish a record recognised by the FIA.

Speed Demon is officially the fastest piston engined car ever built, during the 2012 season a film crew from Ron Kirby Productions followed the team behind it and produced this stunning documentary. Watch it now!
