MSD Coils and Pertronix Ignitor

[jlandry@domain.elided (John A. Landry)]

Darrel's right.  Take a look at this, right off the MSD web site.  Take
special note of how MSD mentions ballast resistors.  Their "stock" coils are
the same, but supplied with a 0.8 Ohm ballast resistor to increase the primary
circuit resistance.  All I need do is plug my ballast resistor (already on the
truck) back in line.



MSD BLASTER COILS

If you are looking to upgrade your stock coil, or want to compliment the
performance of your MSD Blaster Ignition, MSD 5, 6 or 7, the Blaster Coil line
is the right choice. All of the Blaster Coils are designed for improved spark
output!  Special 100:1 windings are used to provide maximum build-up of
voltage! These windings are held secure and kept cool in an oil filled metal
canister. The tower assembly is molded of durable alkyd material due to its
high dielectric characteristics while wide spaced brass primary terminals
prevent the possibility of spark.
There are several versions of the Blaster Coil available. All of them have the
same internal specifications, but have different housings or components. Each
Blaster Coil can be used with a stock ignition, Blaster Ignition, MSD 5, 6 or
7 Ignition Control. Most late model vehicles with electronic ignitions do not
require a ballast resistor, check your ignition and manufacturers
specifications to determine if a ballast is required in your application.

BLASTER 2 and 3 SPECIFICATIONS:

Output Voltage:          45,000 Volts maximum
Operating Voltage:       12VDC
Primary Resistance:      0.7 Ohms
Secondary Resistance:    10,500 Ohms
Turns Ratio:             100:1

STOCK APPLICATIONS

The following Blaster 2 Coils are supplied with a 0.8 ohm ballast resistor and
a terminal and boot to fit most applications.  The ballast resistor must be
used with stock Points Ignition and Mallory Unilite applications.  Note: These
are the same coils as the other Blaster Coils, except they are supplied with a
ballast resistor.
