Built for pro-level oval track racing. It gives you serious spark energy and total control. You get 135 mJ of spark energy with this system. Even at high RPM, it keeps combustion clean and strong. The built-in RPM limiter adjusts from 6000 to 9900 RPM in 100 RPM steps. That means you can dial in exactly what your engine needs. Because the box uses sealed construction, it’s fully waterproof and track-ready in any condition. In addition, the harness is plug-and-play with weather-pack connectors. You also get the mating connectors and pins, so installation is simple and fast. This CD-1 Super Speedway Ignition Box works with all 8-cylinder engines that use either a magnetic pickup distributor or a 4-magnet crank trigger. It runs on 16-volt race systems (8–20V range) and is protected against reverse polarity. Best of all, it draws less than 5 amps at 8000 RPM. It’s a compact, tough, and efficient solution for serious racers.
