The Racing Ford DUI (Davis Unified Ignition) is a one-piece ignition system that is designed
for 9000 RPM's. It has the Racing DUI Coil mounted inside the distributor cap and the Dyna-
Module inside the distributor. It is an easy drop in installation with a one wire hook-up and no
spark boxes are needed! Don't be fooled by cheap imitations, this is the original one-piece
Ford distributor that will turn up to 9000 RPM's!

The Racing DUI only draws 2 to 3 amps off of the battery, whereas point type ignitions and
spark boxes drain 10 amps or more. The Racing DUI Coil and the Dyna-Module produce a
long duration spark allowing plug gaps to be opened up to .050"-.055"! The Racing DUI
sends twice as much spark into the combustion chamber over a Magneto, which can only
run a tiny .015" - .025" gap. Horsepower is gained because more fuel is burned on each
piston stroke. Along with a more efficient burn, the spark plugs will stay cleaner longer. The
Racing DUI also makes point-type systems obsolete and saves time and money because
points do not have to be changed for every race. The Racing DUI Coil is designed to run
cooler than all other coils, including oil-filled coils. Cross fire is eliminated by the use of wide
terminal spacing within the cap.

The Racing Ford DUI advance system is curved for easy starting, better throttle response
and more power. All of the moving parts are hand fitted to assure the smoothest advance
curve possible. The weights are fabricated from very high quality hardened steel which
makes them virtually maintenance free. More timing can be run, without detonation, than
with stock distributors and after market curve kits. Each distributor is tuned on a distributor
machine for the engine it is being installed in. The advance curve is determined by the specs
of the vehicle and engine. The Racing Ford DUI is available with or without vacuum advance.
