Feature-for-feature, Crane’s HI-6 multi-spark CD ignition for racing or street applications is the industry’s best value. It delivers higher spark-gap current (when used with a companion Crane FireBall LX-92 coil) than the competition and can handle engines with compression ratios to 14.5:1. Important features include surface-mount construction, fully digital components that are sealed in urethane for protection against heat, dirt, water and vibration, plus a rotary dial-adjusted rev limiter. It supports points, module or magnetic triggers.
The HI-6R is ideally suited for use with high compression (to 14.5:1) normally aspirated engines or those equipped with power-adders (blowers, turbos, nitrous). It offers exclusive cross-fire protection for supercharged or turbo installations, and has a built-in timing retard (with optional control module, p/n 6000-6425 for in-car adjustments). With a digital design, surface-mount construction, and urethane sealing of all internal components, it’s proven to be the most reliable CD ignition on the market today. Shock mounts included for racing applications.
Engineered for drag racing, the HI-6DSR features a dual stage rev limiter to facilitate setting separate RPM limits for staging and down-track control. It delivers exceptional spark-gap current that can optimize combustion in normally aspirated (to 14.51 ratio) and boosted (nitrous, turbo, blower) applications. It can also be equipped with a remote timing retard. You will find the HI-6DSR to perform better than competitive units costing substantially more. It’s an engine saver in a digital package that is sealed against shock and vibration.
