Former Pontiac Motorsports Manager John Callies: Epic Golden Era NASCAR Stories & Garage Tour!
What happens here
The interview transitions to John's office, where he showcases various prototype engine components and tools displayed in glass cabinets. He demonstrates a classic oil ring and highlights a project involving a two-wheel fuel lifter designed to withstand extreme cylinder pressures in Top Fuel dragsters. He explains the challenge of achieving proper valve opening against high pressures. He also displays a vintage piston with narrow rings from 1982, noting its advanced design for its time. He also shows a set of weight samples in magnesium, aluminum, and iron, illustrating the significant weight differences between the materials for the same volume.
Goal: Illustrate specific engine innovations and engineering challenges.
