The Year of the Demon: Headed for 500 mph in 2012

Completed Speed Demon resting in her element


The Speed Demon, a single-seat road rocket, currently holds the record for the world’s fastest turbo charged race car with a top speed, to date, of 462.345 mph!  Coastal Enterprises custom bonded blocks of PBLT-10 to be machined for the tooling of the Speed Demon.

The Speed Demon is about 30’ in length and the composite body was fabricated in 3 sections.  Coastal Enterprises custom bonded 7 different sized blocks of Precision Board Plus for the project.

The blocks were machined at Trans FX in Camarillo, CA and the fabrication done by Jon and Patricia Sharp of Nemesis Air Racing.

Ron Main, one of the Speed Demon’s owners, was very pleased with how well Precision Board Plus PBLT-10 worked for the molds.  “We had to choose between aluminum or Precision Board, and were pleased with our choice and how everything turned out.  It really saved a lot of time and money to have the net shapes delivered, ready to machine.”

Ron goes on to say, “The unique thing about PBLT-10 is that we didn’t have to make a plug first – we went straight from CAD to machining the mold.  We eliminated the plug process, which was a huge advantage. We saved time and saving time is saving money. Start of car to firing the engine was only 4 months!”

Ron has a great attitude and when he wakes up in the morning, he can’t wait to get to work.  Newly retired, he’s working hard with the ‘Save the Salt’ Foundationas well as promoting and changing the cars.  As Ron so eloquently puts it, “I work with a great team and we’re all like the ‘Bad News Bears’ but when it comes to racing, we all come together.”

Turn up the volume and hold onto your seat when you watch this video and see George Poteet take the Speed Demon to 462.345 mph!!


The Speed Demon is touring and currently resides at the NHRA Museum in Pomona, CA for just a couple more months.

The goal for the Speed Demon in 2012 is to get it up to 500 mph!  This could be one of the reasons 2012 is the Year of the Demon!
