Product Description

The Racing D. U. I. Distributor is capable of turning 9000 RPM's. That's almost double the output of a stock H. E. I. ! Years of engineering experience and modern technology allowed us to develop a high voltage coil and high dwell module that would turn the high rev's needed for today's racing engines. No external spark boxes or coils are needed as our race coil and module fit inside the distributor for an easy drop-in installation with a 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 makes the coil produce a longer duration spark. The combination of these two components produces an intense spark that is unmatched by stock HEI's and other "performance" ignition systems, particularly those using the external spark boxes. The result is a more complete burn of the fuel mixture for more horsepower. Amperage draw off the battery is minimal as the Racing D. U. I. only pulls 2-3 amps, whereas other aftermarket ignition systems draw 10 amps or more. For those not running an alternator, this prevents the battery voltage from dropping too quickly. The Racing D. U. I. also sends 2-3 times more spark into the combustion chamber than a magneto. The plug gap with a mag is a mere 015" -. 025", so horsepower is gained with the D. U. I. because more fuel is burned on each piston stroke. The wider gap also helps spark plugs stay cleaner longer which means fewer plug changes at the track.
