Story
The Mazda RX7 was an outstanding car. It won its first race at Daytona in 1979 and shattered the opposition. The car was not to be unnoticed, as its strident cry was nearly deafening. Yet, the car was barely developed, as its components were stock. When the weaknesses of the car were fixed, it would become the most successful racer to be built. The car's potential had been revealed right from the beginning, and everything was hammered home. Brakes were outstanding, as was the handling. While the works cars would dominate the 1979 season, Don Devendorf still won the GTU Championship. Racing Beat would run two cars in the 1980 Championship, with Walt Bohren and Jeff Kline driving. Cars were quite different from the initial cars, with most stock parts systematically eliminated. The rear axle was no more the stock one, but a Halibrand unit, with transfer gears That could be changed in minutes. The suspension was a collection of large-diameter steel tubes, while the anti-roll bar was a massive 32mm one. Two ignition black boxes filled the left seating position. The engine was a 1.1 rotary Mazda, which gave 280 hp. They had peripheral intake ports and narrower apex seals. A Lucas timed fuel injection also replaced the Weber carburetor. The location of this low mass engine allowed a fine weight distribution. The engine was one of the strength of the car. The car was so dominant in the first place That it was awarded à weight penalty. But it did not prevent the drivers from dominating. Racing Beat proved its ability with rotary racers. The domination was outright.
