Speed Demon (car)

Speed Demon is a land speed racing car built in 2010 by Ron Haim for George Poteet.

Speed Demon at Bonneville in 2010

In September 2010, George Poteet made a serious attempt to break the flying mile and flying kilometer record for piston-engined wheel-driven cars. Speed Demon is powered by a 299 cu in (4,900 cc) aluminum block 'Hellfire' V8, built by Kenny Duttweiler.[1] Their effort was thwarted by a number of parts failures. The team stated their intention to return in 2011 to set a record over 450 mph (724 km/h), and at the 2011 Bonneville Speed Week, Poteet achieved 426 mph (686 km/h) [2]

After making "the fastest piston engine pass ever",[3] turning in a two-way average of 437.183 mph (703.578 km/h).[4] (Because this was not done within the two-hour limit demanded by FIA, the record is not considered official.)[5]

In 2012, Speed Demon set an official record at 439 mph (707 km/h).[6]

Speed Demon was displayed at the 2018 Detroit Autorama.[7]

Poteet intends to attempt the absolute record for wheel-driven cars, currently held by Don Vesco’s Turbinator.[8]
