MSD
6A Ignition System:
The MSD 6A is the base model of the capacitive
discharge multiple spark 6 Series design. Whether you have a powerful
street machine, hard working truck or trick street rod, the powerful
multiple sparks of the MSD 6A will ensure complete combustion. Benefits
such as quicker ET’s, easier starting, reduced plug fouling,
more power and even increased fuel economy can be expected with
the 6A’s high energy multiple sparks.
Like all of the MSD 6 Series Ignitions, the 6A will work with virtually
any vehicle as long as it has a 12-18 volt electrical system. It
can be triggered using breaker points, a magnetic pickup or the
output of an electronic amplifier. All necessary parts and wiring
instructions are included. |

6AL Ignition System:
The 6AL shares the same proven circuitry of the 6A with the addition
of a built-in adjustable rev limiter. The combination of powerful
sparks with the safety of a Soft Touch Rev Control is what makes the
6AL the most popular ignition control in the world.
MSD first developed the Soft Touch rev control to prevent overrev
damage to your motor in the event of a missed shift or driveline failure.
The rpm limit is adjustable in 100 rpm increments with MSD’s
plug-in modules. When the engine reaches your selected limit, the
Soft Touch circuitry begins dropping the spark to various cylinders.
On the next cycle, these plugs are fired again to prevent fuel from
loading up in the cylinder. The result is a smooth and accurate limiting
action without backfires or roughness. The Soft Touch Rev Control also opens the door for you to add rpm
accessories such as a Two Step Rev Control. A Two Step allows you
to set two rpm limits, one for a holeshot rpm and another for overrev
protection.The 6AL is supplied with rubber shock mounts and modules for 3,000,
6,000, 7,000 and 8,000 rpm. |

6BTM Ignition System:
The 6 BTM is ideal for engines with a turbo or supercharger. Not only
will the engine benefit from MSD’s full power CD sparks, but
there is also an adjustable boost/timing retard circuit to prevent
detonation.
When your supercharger (turbo or blower) forces the air/fuel ratio
into the engine, the cylinder pressure inside the combustion chamber
increases. The result is a great amount of power but this can also
lead to detonation which can result in severe engine damage. The 6
BTM lets you dial away detonation by retarding the timing in relation
to the boost pressure. By electronically controlling the ignition
timing your engine can run on the threshold of detonation to obtain
maximum power and efficiency.
The BTM features a dash mounted control knob that lets you adjust
the amount of timing retard. It can be adjusted from 0° per pound
of boost to 3° per pound. The boost pressure is monitored by a
sensor built into the MSD.
The 6 BTM also shares the Soft Touch Rev Control of the 6AL Ignition
for overrev protection. The BTM is supplied with rubber shock mounts
and rpm modules for 3,000, 6,000, 7,000 and 8,000 rpm. |

7AL-2 Ignition System:
The 7AL-2 is the choice of professional racers from six second Pro
Stocks to Monster trucks. The CD circuits deliver full energy sparks
to the plug throughout 14,000 rpm ensuring that even the most exotic
fuel combinations are thoroughly ignited. A special coil coupler increases
spark duration and protects the Ignition in the event of coil failure.
MSD's accurate Soft Touch Rev Control is built into the 7AL-2 so our
Module Selectors and other rpm controls can easily be connected.
To survive the demands of heavy duty racing applications, the circuit
boards receive a heavy duty coating of Humi-Seal compound. This substance
seals the circuits for resistance to vibration and moisture. Heavy
duty vibration mounts are also supplied. The 7AL-2 is a proven winner
on tracks around the world. |

7AL-3 Ignition System:
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 solenoid.
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. |
