SpeedDemon Breaks World Land Speed Record

George Poteet

On Monday September 17, 2012, George Poteet, driving the Poteet and Main “Speed Demon” Streamliner, at the Mike Cook Shootout at the Bonneville Salt flats in Utah, set a new FIA International Category A, Group1, Class 10 records in the kilometer and mile distances by averaging the following two way flying start speeds. Kilometer 707.408 KPH and mile 439.562 MPH, and the speed for the mile 439.024 Miles per hour and the kilometer at 706.540 KPH.  This makes the Speed Demon the fastest piston engine wheel-driven car in history. No other piston-engine car has ever achieved this speed. 


The car was powered by a Kenny Duttweiler 368 cubic inch “Hellfire” engine

The Bonneville Hot Rod Magazine Top Time Trophy


Poteet & Main Speed Demon has won the Top Speed Trophy for the last 4 consecutive years. Every year that Speed Week has been run since 1949, HOT ROD magazine has issued the Top Time Trophy, the award for the single fastest pass of the meet, regardless of if the pass is a record or not. To many, this is the ultimate prize for Speed Week.

2012 Speed Demon sponsors

Every year, we begin working immediately after the last run to improve the car based on what we have learned. Without the tireless efforts and material support of these sponsors, we would not be able to go out each year with the prospect of bettering our speeds from the previous year.

You can show your appreciation to our sponsors by buying and using their ”Speed Demon tested and approved“ products in your car.
