Pit Stop USA is The Online Motorsports Superstore! We feature Hilborn Fuel Injection Systems for sprint cars. Fuel Injection Engineering Co., Inc. is the original designer and sole manufacturer of the Hilborn fuel injector. Hilborn provides a complete product line of Hilborn fuel injectors, Hilborn fuel pumps, and related parts to fit a variety of engine types and racing applications. Sprint Car racers have relied on Hilborn injection systems than any other brand. Hilborn fuel injectors have been successfully used in all types of racing including oval track, drag, dry lakes, super modified, off-road, motorcycle, tractor pulling, hydroplanes, and Indy Lite series. Fuel Injection Engineering has been in business since 1948, and has a proven track record! The primary function of the Hilborn fuel injector is to increase horsepower, and from the racer's viewpoint, this is still its' greatest asset. The horsepower gains are fundamentally due to two reasons: 1. Increased volumetric efficiency because of the elimination of the boosters which inherently restrict the flow of air in carburetors. 2. Absolutely equal distribution of fuel flow and air flow to the cylinders. In the early 1960's a new Hilborn fuel injection system was developed for turbocharged engines. This system proved so successful that fuel injection was introduced to turbocharged engines at the Indianapolis 500 race. In a very short time, every car in the race was turbocharged and Hilborn injected. For the last 50 years, the Hilborn Fuel Injector has dominated in racing circles... from sprint cars to motorcycle racing, to 34 wins at the Indianapolis 500. We feature Hilborn Fuel Injectors, Hiborn Fuel Injections Systems and Hilborn Fuel Injector Pills at low everyday prices!
