![]() ![]() At the same time, the electronic injectors will subtract its fuel delivery by an equal amount so that the mixture is never deviated during the transition. Based on rpm, throttle position and boost, the mechanical system will kick in and match a certain flow. “There was an Aeromotive electric pump to start the engine, and then a Waterman cable-driven mechanical pump takes over for the run.”īasically, the electronic injectors are used for startup and low speeds. “Coming out of mile five, 11.5 gallons of fuel per minute were flowing to the engine,” said Shane Tecklenburg, who helped tune the fuel-injection system and noted that the car even needed a compound approach to the fuel-pump strategy. Built by Kenny Duttweiler, the engine features a unique hybrid fuel system with 16 electronic injectors and eight mechanical injectors to feed methanol into the cylinders. Powering the Speed Demon is a twin-turbo 557-cubic-inch big block Chevy engine that pumps out more than 3,000 horsepower with around 30 pounds of boost. That’s the fastest any piston-engine, wheel-driven vehicle has ever been recorded on land. The impact of fuel injection, both electronic and mechanical, was never more apparent than in August on the Bonneville Salt Flats, where 72-year-old George Poteet and his Speed Demon streamliner jolted the AA/BFS land-speed record from 417.020 mph up to 470.015 mph, posting an astounding final exit speed of 481.576 mph. ![]() It takes a village of parts to build a winning system, and today’s aftermarket tech reps are equipped to provide the clearest path toward optimizing all products involved. ![]()
