Flatfire is more of a garage built car than their liner.
OK, let's assume that Flatfire is "home made".
Speed Demon on the other hand, may have more than 1500 hours of computer time.
You know the method of hand shaping the form so that you can lay up a mold and make the body?
Speed Demon's body was designed on a computer, the mold was machined directly on a 5 axis mill.
And who made the body? Ron when to Burt Rutan at Scaled Composites. I hear rumors of Kevlar and Carbon Fiber, but I really think the body is made out of cubic dollars.
And yeah, he didn't get a record at Bonneville and the 401 was only "an exit speed".
Can't wait for the Top Speed Shootout!
