    MSD Ignition 8222 - MSD Blaster Coil Details

    High-Vibration Blaster Coils

    In applications such as off-road, marine or other harsh conditions, the MSD Blaster High Vibration Coil is the best choice. The sturdy metal housing of the High Vibration Coil is completely pot­ted with a premium grade epoxy to completely encase the coil's primary and secondary windings. This protects the coil's internal components from high and low frequency vibrations that are commonly experienced in racing.

    Coil Specs:

  • Turns ratio: 100:1
  • Primary resistance: .7 OHMs
  • Secondary resistance: 4.5K OHMs
  • Inductance: 8 mH
  • Maximum voltage: 45,000 Volts (Tested with 6AL Ignition)
  • Peak current: 140 mA
  • Spark duration: 350 uS


  • Improved output coil for electronic, Point, Blaster or MSD 5, 6, and 7 Series Ignitions (ballast resistor required for points)
  • Alkyd tower with high dielectric properties is less prone to carbon tracking
  • 100:1 turns ratio and lower primary resistance produce high voltage output
  • Metal canister is encased with epoxy to protect the windings from high vibration applications
  • 50 State Legal
  • CARB E.O Number D-40-37

    If looking to upgrade your stock coil or to complement the performance of your MSD Blaster Ignition or MSD 5, 6, or 7, the Blaster Coil line is the right choice. All Blaster Coils are designed to improve spark output. Special 100:1 windings are used to provide maximum build-up of voltage; they're 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 different housings or components. Each Blaster Coil can be used with a stock ignition; Blaster Ignition; and MSD 5, 6, or 7 Ignition Control. Most late model vehicles with electronic ignitions do not require a ballast resistor (check your ignition and manufacturer specifications to determine if a ballast is required for your application).
