Killshot Series

The Aces EFI Killshot series offers an intuitive, high-performance pathway for enthusiasts looking to transition their classic engines into the modern era of electronic fuel injection. Designed to seamlessly fit standard 4150-flange four-barrel intake manifolds, the Killshot category stands out by combining the retro, low-profile aesthetic of a traditional carburetor with advanced 32-bit technology and self-learning capabilities. What truly makes the broader Killshot family unique is its adaptable engineering approach to system architecture, designed to accommodate any builder's specific needs. Rather than forcing a single solution, the lineup offers tailored configurations: for those seeking benefits in longevity, durability, and future-proofing, the flagship Killshot models utilize a remote-mounted engine control unit (ECU), which keeps the system cooler and prevents wear. Conversely, for enthusiasts prioritizing a streamlined, clean installation with minimal wiring, models like the Killshot Fusion feature an ECU integrated seamlessly into the throttle body. Regardless of the configuration chosen, the entire series delivers the precision of real-time fuel adjustments and exceptional reliability, ensuring peak performance whether you are navigating dense traffic or pushing a race engine to its absolute limits.

Royal Flush Series

The Aces EFI Royal Flush series is the ultimate fuel injection solution for builders who demand absolute control over both fuel and spark in high-performance or boosted applications. What distinctly elevates the Royal Flush category above the rest of the Aces lineup is its innovative integration of a state-of-the-art Electronic Fuel Injection controller and a high-output Capacitive Discharge Ignition (CDI) system within a single, remote-mounted ECU. By utilizing this state-of-the-art CDI technology, this system generates an intensely hot spark to burn fuel with maximum efficiency, unlocking peak horsepower while providing advanced features like a 2-step rev limiter for launch control and step retard for nitrous applications. Capable of supporting up to 650 horsepower through a standard 4150-flange, four-barrel throttle body, the Royal Flush maintains Aces' signature remote ECU architecture, safely isolating these powerful internal electronics from the destructive heat and vibration of the engine bay. With its superior engineering and high-performance capabilities, the Royal Flush is the clear answer for those who need the most out of their classic engines.

Deuces Wild Series

The Aces EFI Deuces Wild series provides an advanced bolt-on electronic fuel injection solution specifically engineered for classic engines utilizing a 2-barrel, 2300-style intake flange. While the larger Killshot series caters exclusively to 4-barrel, high-horsepower applications, the Deuces Wild is designed from the ground up for stock-to-mild engine builds, compact engine bays, and enthusiasts who want to retain their original two-barrel intake manifolds. Despite its specialized, low-profile footprint and support for up to 350 horsepower, the Deuces Wild makes zero concessions in performance. It utilizes the same advanced 32-bit processing power, self-learning fuel tables, and signature remote-mounted ECU design found across Aces' catalogue, isolating vital electronics from engine heat and vibration to ensure steadfast, long-term reliability.
