THEORY OF 6 SERiES igNiTiON
CAPACITIve DIsChArge
The MSD 6 Series Ignitions feature a capacitive discharge ignition design. The majority of stock
ignition systems are inductive ignitions. In an inductive ignition, the coil must store and step up the
voltage to maximum strength in between each firing. At higher rpm, since there is less time to charge
the coil to full capacity, the voltage falls short of reaching maximum energy which results in a loss of
power or top end miss.
The MSD Ignition features a capacitor which is quickly charged (within one millisecond) with 460
- 480 volts and stores it until the ignition is triggered. With the CD design, the voltage sent to the coil
is always at full power even at high rpm.
MuLTIPLe sPArks
The MSD 6 Series produces full power multiple sparks for each firing of a plug. The number of
multiple sparks that occur decreases as rpm increases, however the spark series always lasts for 20°
of crankshaft rotation. Above 3,000 rpm there is simply not enough "time" to fire the spark plug more
than once, so there is only one powerful spark.
rev LIMITer
6AL, 6ALN, 6BTM: These ignitions are equipped with built-in Adjustable Soft Touch Rev Controls.
MSD Rev Limiters are adjustable with plug-in modules which are available in 100 rpm increments.
The Soft Touch circuitry provides a smooth and accurate rev limit by dropping the spark to individual
cylinders. The Soft Touch produces a load-free rev limit that is within 1% of the selected rpm.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
