MSD 7AL-3, PN
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 a RPM activated switch that
can activate components such as a micro-switch on the shifter or a nitrous
Many race engines with crank trigger systems
or locked out distributors will benefit from the 7AL-3's 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 it's mechanical setting. One last option
is an rpm activated switch. This feature 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.
