Guttu Offy Special 1/4-Scale Race Car by Ron Guttu, 2007
The 1928 Ford Model A was a typical donor car for the development of the early Harry Miller Race cars. Such items included the steering box, axles, differential, springs, and the transmission; although most were highly modified for racing.
In this model, the miniature Offy engine was scaled from drawings of the full-size engine and sports Ron’s custom made Winfield carburetors. Ron says it runs best on E-85 Ethanol and spark ignition. Stainless steel was used to fabricate almost everything except the engine, transmission, differential, rims, and body. The model has functional gauges, pedals for the accelerator and brakes, shift lever for forward and reverse, and an external hand brake. The hand pump pressurizes the fuel tank that is located behind the driver’s seat and the lubrication is via dry sump with the oil tank located between the driver and engine. Also it is equipped with steering, leaf spring suspension, friction shocks, and Ron’s custom-made spoke and splined knockoff wheels
Ron built this model as a tribute to his Father who owned and raced the full-size car in the mid 1920s. It is almost exact- even down to the numbers and lettering on the body. Except for the engine Ron fabricated everything from memory and a few family photos of his Dad’s race car. This model measures 32 inches long, 16 inches wide, 13 inches high, and weighs 25 pounds.
