What You Need To Know About Mechanical Fuel Injection - Retro Tech
Long before electronic fuel injection or even performance Holley carburetors, high-end racers operating primarily at wide-open throttle used a purely mechanical, constant-flow fuel-injection system first pioneered by Stu Hilborn in the late '40s.Long before electronic fuel injection or even performance Holley carburetors, high-end racers operating primarily at wide-open throttle used a purely mechanical, constant-flow fuel-injection system first pioneered by Stu Hilborn in the late '40s, a system that is still preferred today by many drag racers and Sprint Car racers, particularly those using alcohol fuels, and it's the thing to have in a retro gasser, which is hugely popular now. Even in 2010, Hilborn systems and its close relatives continue to hold sway not only in nostalgia drag cars, but also in those higher-end Sportsman and professional classes where allowed by the sanctioning body's rules. And let's not discount its visual appeal, either: The massive injection stacks poking through the hood and its badass belt- or cam-driven mechanical fuel pump practically scream that the car is a serious player. But making them work and keeping them working long-term requires regular attention, constant maintenance, and (gasp!) actually turning a wrench. Although Hilborn is specifically referenced in this article, the same basic principles apply to competitive constant-flow, mechanical systems, including the still-available Kinsler and Enderle setups, as well as the Crower units now serviced by Ron's Racing.
