MSD

The most complete drag racing ignition available! The 7AL-3 is based off the well proven 7AL-2. It features the same capacitive discharge multiple sparks plus offers 20% more primary voltage and an additional 35% more spark energy. Not only is the 7AL-3 packed with more power but it also features a host of drag racing accessories. A built-in Three Step Rev Control provides three different rpm limits that can be used for the burnout, holeshot and top end. The rpm limits are adjustable with easy to access plug-in modules and will deliver consistent performance on each run. A Multi-Step Retard features four different modules that can be activated as well as an RPM activated switch that can activate components such as a micro-switch on the shifter or a nitrous solenoid. Many race engines with crank trigger systems or locked out distributors will benefit from the 7AL-3s built-in start retard option. During cranking the start retard will retard the timing 25° allowing the engine to turn over easier. When the engine starts, the timing will go back to its mechanical setting. An rpm activated switch allows you to activate a solenoid or shift light at an adjustable rpm. When the engine hits the desired rpm, the component is activated and whenever the rpm falls below that amount it is deactivated. The increased output and built-in racing features make the MSD 7AL-3 the best and most complete high performance drag racing ignition available.
