Crane HI-6 Ignitions

Crane tested its new HI-6 ignitions (with optional PS-91 coils), they produced twice the ignition energy of a leading competitor's boxes. They're designed to work with engines from 10:1 to 14.5:1 compression ratios, nitrous, superchargers, or turbos. Made for street and racing use, they come with Crane's "Plug-n-Go" universal harness to cover most installations, with optional harnesses available separately. Their built-in rev limiter automatically drops cylinders in firing order to prevent fuel loading, and is adjustable by increments of 100 from 600-9,900 rpm without any chips. Other built-in features include a tach accuracy check, a system problems check for easy problem diagnosis, and crossfire protection for supercharged and turbo applications. They feature solid-state construction that's immune to vibration and shock, and an anodized heat-sink shell for reliability. Crane also offers them in Import Power versions that have the same features and are available in 4 different colors. They're compatible with points and electronic ignitions and work with 4, 6, and 8-cylinder engines with distributors.
