Fun Facts
Top Fuel ragster's 500-inch Engine makes more horsepower then the first 12 rows at Daytona Under full throttle, a dragster engine consumes 2 gallons of nitro per second, the same rate of fuel consumption as a fully loaded 747 but with 4 times the energy volume. The supercharger takes more power to drive then a stock car. Even with nearly 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into nearly-solid form before ignition. Cylinders run on the verge of hydraulic lock. Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder. At stoichiometric (exact) 1.7:1 air/fuel mixture (for nitro), the flame front of nitromethane measures 7050 degrees F. Nitromethane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases. Spark plug electrodes are totally consumed during a pass. After ½ way, the engine is dieseling from compression-plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting of it's fuel flow. If spark momentarily fails early in the run, unburned nitro builds up in those cylinders and then explodes with a force that can blow cylinder heads off the block in pieces or blow the block in half. Dragsters twist the crank (torsionally) so far (20 degrees in the big end of the track) that sometimes cam lobes are ground offset from front to rear to re-phase the valve timing somewhere closer to synchronization with the pistons. To exceed 300mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. But in reaching 200 mph well before 1/2 track, launch acceleration is closer to 8G's. If all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs $1000.00 per second. Dragsters reach over 300 miles per hour before you have read this sentence. |
Joyce Julius reaffirms, “Automotive Sponsorship WORKS!” While Joyce Julius and Associates measures the value for the sponsor as compared with equal time on TV commercials, she points to an example of her earlier days working at Domino's. In 1982, when people nationwide were asked to name the top three pizza distributors, Domino's was only named by 7% of those who responded. This type of survey, where people are asked to name the top three of something with no help from the interviewer is called unaided awareness. Their unaided awareness was 7%. Domino's was known on college campuses but never had a nationwide advertising campaign. In 1982, Domino's took their entire national advertising budget, which was still small, and bought an Indy Car instead. They used the money to put the Domino's logo on the car; they sponsored races and established a mobile pizza store that appeared at the races. Three years later, Domino's unaided awareness was 87%. This increase occurred without ever buying a single ad. Now that's exposure! |
