Hilborn

Stuart Hilborn invented the fuel injection system and it became the system of choice in racing, beginning with his hot-rod V8 and then the Meyer & Drake Offys. He is still active and, like the others of his generation, is using the computer to design and manufacture his products. One of them is an experimental rotary-valve throttle design to be tested on an IRL/Aurora engined car shortly. This provides a nice introduction to the man, leading on to the thought and reality of continuous change and improvement in racing, by racing people having the competitive instincts of the Racer’s Edge.
