    Re: DD 8V71T specs. What components went into turning 435 hp to 462 hp in later year

    There are many ways to hot rod an engine. It is simplistic to just say "burn more air and fuel". There are a lot more ways than that to increase output. The most basic is to increase compression ratio (boosts low end torque), and move the torque curve higher in the rev range (peak torque occurs at higher rpm) to increase horsepower.
    Why limit yourself to simply changing injectors?
    My engines have NA pistons (compression ratio increase), bigger injectors, different cams and cam timing, different blower drive ratio, bigger turbos, etc etc etc.
    When going for more output the competent engineer will change everything.
