Speed Demon at Bonneville in 2010

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

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 intended to attempt the absolute record for wheel-driven cars, currently held by Don Vesco’s Turbinator , but died on July 16, 2024. [8]

An open-wheel car is a car with the wheels outside the car's main body, and usually having only one seat.

The GT2 is significantly lighter than the Turbo due to its use of rear-wheel-drive instead of all-wheel-drive system and the reduction or removal of interior components. As a result, the GT2 is the most expensive and fastest model among the 911 lineup.
