1920 TNT Indy Car

The Miller TNT Indy car 1920 was a high-speed race car that competed in the Indianapolis 500 from the years 1920 to 1928. This car was designed and built by Harry Miller, an engineer, and race car builder who was known as the “King of the Speedway” during his heyday. The Miller TNT Indy car 1920 was used by popular racers such as Wilbur Shaw and Ralph DePaolo to win the Indy 500 championship.

The Miller TNT Indy car 1920 used a powerful 183 cubic inch, inline 8-cylinder engine, which was capable of producing an impressive 145 horsepower at 5500 rpm. The engine was positioned at the front of the car beneath the hood, and it was connected to a 4-speed manual transmission. The car had a wet sump oiling system and a dry disc clutch, which provided a smooth and consistent ride during races.

The Miller TNT Indy car 1920 had a lightweight frame made of chrome-molybdenum steel, which was light and strong. It was an open-wheel race car, meaning the wheels were not shielded on the sides, which made the car especially aerodynamic. The car had two parallel side rails, which were supported by a series of diagonal and vertical braces. The front and rear wheels were attached to a rigid axle, and there were no suspension systems in place.

The Miller TNT Indy car 1920 had a sleek and aerodynamic body with a low profile, which helped to reduce air resistance and increase speed. The body was made of aluminum and featured a pointed nose and tapered tail. The driver sat low in the car, behind the engine, and was protected only by a small windscreen. The car had no roof, doors or windows, which made it extremely light and agile.

The steering system of the Miller TNT Indy car 1920 was a worm-and-sector type, which provided accurate control and responsiveness. The car was also equipped with hydraulic brakes, which were more effective in slowing the car down compared to the earlier drum brakes.

In conclusion, the Miller TNT Indy car 1920 was a marvel of modern engineering that showcased speed and power, which made it a force to be reckoned with on racetracks across the world. The car's technical details such as its powerful engine, lightweight frame, smooth transmission, and responsive steering system, made it a remarkable feat of engineering, which continues to inspire the design of modern race cars to this day.
