First of all I'm not looking for bragging rights. I'm looking at something to improve the ignition system on my truck for more efficient starts and over all performance. The explaination on the site seems to make alot of sense on how the system can improve that. See this: 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.
That is taken from their instruction sheet for the box I was looking at for a 235 stovebolt.
