How does Performance Distributors DUI distributor compare to a multi-spark ignition system?
The DUI is not like the multi-spark systems that utilize an external capacitive discharge ignition box. The DUI is a one piece ignition system with no external components. The DUI incorporates a high dwell module inside the distributor that increases the coil saturation time. The longer saturation time makes the coil produce one long duration spark as compared to several multiple sparks. The longer duration spark will improve throttle response and low end power. In conjuction with our 50,000 volt coil, spark plug gaps can be opened up to .055″. Most spark box systems recommend a gap of no larger than .045″. The DUI’s coil and module only draw 2-3 amps. Most spark box ignitions draw anywhere from 6-10 amps. The lower amperage draw of the DUI allows it to run cooler, making it more reliable than the spark box. The less amperage draw is very important if you are a racer that just runs a 12 volt battery with no alternator. Most importantly, the DUI distributor is custom tuned on a distribu
