Founded in the mid 1970s by the late legendary racer and ignition wizard Kelly Davis, Performance Distributors is well known to oval track racers around the country as the manufacturer of the D.U.I. (Davis Unified Ignition). While Performance Distributors was the first company to make a performance HEI distributor, its innovation never stopped and now it's back with the brand-new "Ultimate Racing D.U.I. Distributor."
The Ultimate Racing D.U.I. Distributor is the latest version of its Racing HEI, incorporating three fantastic new components. First, the distributor features an Instant Timing Knob, which allows you to make timing adjustments quickly and easily without having to use a timing light. Simply turn the knob in one direction or the other to either advance or retard your timing.
This feature means that you no longer need to loosen and re-tighten your distributor hold-down clamp when making adjustments to your timing. It also prevents you from burning your hands making timing adjustments between practice, heat races, and the feature.
The next innovation can be found inside the Ultimate Racing D.U.I. distributor. Performance Distributors' new Rev Limiting Dyna-Module takes the place of large "box" style rev limiters. The Rev Limiting Dyna-Module mounts in the original equipment location. It's adjustable via a small rotary dial on the end of the module from 5,000 to 10,000 rpm. An added plus is that the engineers at Performance Distributors have additional dwell time cranked into it, resulting in a longer duration spark.
Go even deeper into the new Ultimate Racing D.U.I. and you'll find that third new feature, a carbon ultra-poly composite distributor gear. This gear is compatible with any camshaft and is designed to eliminate wear problems and the hassle of replacing gears. Whether you run a solid, hydraulic, factory roller, or a steel billet roller cam, the Ultra-Poly gear will provide unmatched strength and durability.
The Ultimate Racing D.U.I. also incorporates the D.U.I. Coil, brass terminal cap and rotor, as well as a machine-calibrated advance system which insures a super smooth advance curve, maximum performance, and fuel efficiency. The MSRP for the Ultimate Racing D.U.I. is $655 and available directly from Performance Distributors.
