MSD 7805 8-Plus Ignition Control Module with Dual Coil Output

The MSD 7805 8-Plus Ignition Control is a high-performance capacitive discharge ignition (CDI) system engineered for serious race and performance applications. Delivering extreme spark output at sustained high RPM, the 8-Plus is capable of firing single or dual coil configurations, making it a versatile solution for a wide range of engine builds.

Key Features:

• Extreme Spark Output – High-energy capacitive discharge design delivers multiple sparks per firing event at low RPM and a full spark at high RPM
• 36 Amps at 12,000 RPM – Maintains powerful spark energy well into the rev range for consistent combustion
• Up to 15,000 RPM capability – Achieves maximum RPM potential at 14.4 volts for all-out racing use
• Single or Dual Coil Output – Supports both single coil and dual coil setups for maximum flexibility
• Built-In 2-Step Rev Control – Integrated launch rev limiter allows precise RPM limiting for consistent drag race launches
• Wide Voltage Range: 12–18 Volts, Negative Ground – Compatible with standard 12V systems as well as high-voltage race charging systems
• 4, 6, and 8-Cylinder Compatible – Works with a broad range of engine configurations

The MSD 7805 is built for competitors who demand the absolute most from their ignition system. Whether on a bracket car, Pro Street build, or high-revving circle track engine, the 8-Plus delivers the reliable, high-energy spark needed to maximize power and consistency under race conditions.
