D.U.I. HEI Distributor

  • Davis Unified Ignition (D.U.I.) High performance race distributors are a complete, quality built, ignition system that deliver the spark you need up to 10,000 RPM. Research and development has allowed D.U.I. to produce high coil voltage, high dwell modules, and a mechanical advance system which allows for the RPM’s today’s race engines need. All this is accomplished with no external coils or an ignition box which makes for an easy to install one wire hookup. The Racing D.U.I. Coil allows spark plug gaps to be opened up to .055″ and the increased dwell in the Dyna-Module creates longer spark duration. These two components produce a spark so intense that it is unmatched by stock HEI’s and other “performance” ignition systems, particularly those using the external spark boxes. The end result is a more complete burn of the fuel mixture for more horsepower! The Racing D.U.I. also sends 2-3 times more spark into the combustion chamber than a magneto. The wider gap also helps spark plugs stay cleaner longer which means fewer plug changes at the track. These hand built systems are precision tuned on Sun Distributor Machines for easier initial start-up, better throttle response, and more power throughout the RPM range. These self-contained internal coil and module distributors are the only H.E.I. style systems that will spin 10,000 RPM.
