Yes, you are correct in that the TV show stated those facts, however the car was tested WITHOUT any added power, PRIOR to other sponsors coming on board. (3 weeks of runs) What actually happened, and 'what was paid for' are two different things. Bill Fredricks did build the car to break the sound barrier WITHOUT POWER ADDERS. It did "run the number" more than one time prior to the 'new sponsor' coming on board. The car had a limited number of "powered seconds", fuel VS weight. (not what Bill had in mind) Hal was so confident in Bill's work, that he used Bill's 'rocket power' to build a "stunt car" for the movie "Hooper". When Hooper and "Ski" jump the broken bridge, the photo cuts to a fiberglass bodied tube chassis car that is rocket powered. The "stunt car" is out on the Mojave desert, jumping a (record) long distance, and then 'cut into' the movie. The "new sponsor" for the rocket car project was looking for an ACTION packed way to get the US military to look at it's "missle powerplant", and the "Budweiser Rocket Car" project really needed the CASH. Bill, Hal and Stan did the job, and then needed CASH rewrote their story. There's life, and then there's TV!
