Ken Duttweiler Hops Up the New Ford Mustang’s Direct-Injected 2.3L
Ken Duttweiler has been building and modifying engines for more than 60 years. The builder of the world’s fastest internal combustion-powered land-speed-record car is now applying his expertise developing the new Mustang 2.3L, turbocharged, direct-injection, EcoBoost four-cylinder motor. But don’t think of this as a four-banger, think of it as a testing bed for all sorts of future direct-injection tech. “Our goal is big horsepower—over 1,100 in race trim—but we’ve got to take baby steps first,” Duttweiler says. “Like it or not, this is the future of performance. More than 60 percent of the Mustangs sold in southern California have the 2.3L engine.”
First steps are getting the engine to run with Ford’s existing electronics, then figuring out how to tune the factory ECU. After that, “we’ll hop up the existing production-based engine with a series of progressively larger turbos and aftermarket cams.” At some point, “we’ll move to aftermarket direct-injection engine-management systems currently under development. Ford Racing will also have a racing block and heads.” HOT ROD plans to follow along as development proceeds. Stay tuned for future updates.
