First Photographs of Junior 8 Race Car
Head-on view of the Jr. 8 front-wheel drive race car (a Miller product) to be driven by Dave Lewis at the Indianapolis 500-mile race on May 30. This shows the brake drums on each side of the gear housing and the oil cooler at the bottom of the housing. The drive shafts to the front wheels also are visible. Note the cranked rear axle, which allows a lower hang of the frame.
This view shows the arrangement of the super charging device. The device is located just ahead of the dash and is driven from each of the two overhead camshafts. A dust shield is placed just ahead of the supercharger intake and is visible just below the frame at a point opposite the engine. The right front wheel has been removed here to show the spring sus- pension. This view also shows the arch-shaped front axle which as the springs deflect moves in a straight line up and down by virtue of the brackets fastened to the ends of the quarter-elliptic springs.
Some Views of Speedy Race Car – This Will Be Seen at Indianapolis May 30
Dave Lewis at the wheel of the front-wheel drive car he will pilot at this year’s Indianapolis race. This car is brand new for the race and represents a type of construction which may revise the design of passenger cars in the days to come. It is claimed that the front-wheel drive cars will perform better on the turns.
Above is a close-up of Lewis‘ car. At A is shown the hole for insert- ing crank and B shows the dust shield ahead of the supercharger intake. This view shows clearly the manner of springing the front end of the car. It will be noted that there is a decided absence of gracefully curved intake pipes on the engine and that some of the bends are very abrupt. With the supercharger graceful bends of other days are not necessary because the mixture is forced to the engine under pressure.
Left side of the Miller front- wheel drive car. Note the long drag link and the manner of cutting away a portion of the steering wheel rim to give sufficient clearance for the driver.
