Speed Demon Coverage on
11:43:00 ET
Got word couple weeks past that George Poteet got the ride of his life in the Ron Main and Poteet Speed Demon ultra-speed demon. You know, just your average 400 mph grocery getter. As I got the word, driver George was in the third timed mile at Bonneville when the car got in a hiccup and ended up removing the body panels at well over 300 mph.

Speed Demon Status Report
18:05:20 ET
On the first run on the year on 9/12, Speed Demon got a little sideways and rolled several times near the 3-mile mark on the course. [This run was as part of what was supposed to be Mike Cook's Shootout, but was changed to a test and tune session with no official times due to standing water at the end of the long course and surface issues near the beginning.]

George walked away from the car and was taken by ambulance to Salt Lake City for observation. The data loggers showed the crash happened near 370 mph and the strength and integrity of the car/frame was simply amazing, given the forces the car saw during the crash. Everyone who participated in designing, fabricating and maintaining the car over the years can be proud of the fact that George walked away with only bumps and bruises.

George was grateful to everyone who has worked on the car over the years. The outpouring of support an concern was truly overwhelming. George is looking forward to bringing Speed Demon back to set new records in 2015.

Call Speed Demon the little car that can.

The California-based streamliner owned by George Poteet and Ron Main might not run as big an engine as its competitors, but it now can claim to have recorded the fastest piston-driven car time in the 65-year history of the Southern California Timing Association’s Bonneville Nationals, an outing known as Speed Week.

Update: Speed Demon Just Ran 448 MPH! The Streamliner Battle Is Looking Bleak For Others

UPDATE Thursday August 15th, 2013: 9:41 am Mountain Time  SPEED DEMON JUST RAN436 MILES PER HOUR IN THE 5TH MILE WITH AN EXIT SPEED OF 448 MPH!  With that run, the team will surely return to impound and do routine maintenance on the car and take the rest of the day off to prepare for a record return run tomorrow morning, if the engine is one piece. If not, they would only be allowed 4 hours of repair time today in impound and one hour in the morning. We will keep you posted with more as we get it.

Build Update
Do Not Unwrap Till After “SPEED WEEK”
Advanced Alloy Shields™ custom manufactures reusable hard cover thermal insulation systems that are molded to fit directly over hot engine components, up to 3000° F. (1649° C.). Since 1972, they have worked with military and aerospace industries and are one of the most qualified companies for extreme heat control.

You will see Turbo Insulation Shields on nearly all professional race cars with turbocharged engines. Why? Because they help to increase engine performance and protect against the damaging effects of radiant heat.

Exhaust gasses power the turbo spindle; the higher the performance of the engine, the hotter the exhaust temperatures will be. In fact, if you were to open the engine compartment of any high-performance vehicle after it has been driven hard, you’d see a glowing red exhaust-side turbocharger housing.

To avoid damage and sustain optimum performance, it is important to protect the rest of the engine from the 1600 F°+ temperatures that radiate from the Turbo. Covering the turbo housing will also promote cool air intake that translates to increased horsepower and fire protection!
