MSD 8147 Pro Mag 44 Amp Electronic Points Box with Rev Limiter - Red

The MSD 8147 Pro Mag 44 Amp Electronic Points Box is a high-performance ignition control component engineered specifically for the MSD Pro Mag 44 Amp magneto generator. Designed for serious drag racing applications, this red points box replaces traditional mechanical breaker points with solid-state electronic circuitry that delivers faster, more consistent ignition control at every RPM.

The 8147 manages the Pro Mag 44's energy output, generating a long-duration spark and exceptionally fast rise time. The integrated magnetic pickup in the generator provides the trigger signal, while the points box instantly releases the full power of the generator to the coil — resulting in a powerful voltage spike that ionizes the plug gap and reliably ignites nitromethane fuel mixtures. Spark duration is held for a full 26° of crankshaft rotation, ensuring thorough, complete combustion on every firing event.

Key Features:

• Electronic circuitry replaces mechanical breaker points for instant, full-power coil activation
• 26° crankshaft rotation spark duration for complete combustion
• Built-in rev limiter (distinguishes PN 8147 from the no-limiter PN 8145)
• Strong cast aluminum housing serves as both structural mount and heat sink
• Humi-Seal compound coating on all circuits for protection against 300+ mph vibration
• 4-pin Deutsch connectors lock and seal wiring connections to the Pro Mag generator
• Includes vibration mounts, wiring harness, and connectors
• Red anodized finish for easy identification
• Note: Not compatible with the Pro Mag 12 or Pro Mag 20 — designed exclusively for the Pro Mag 44 Amp generator

The MSD 8147 is a race-ready ignition points box built to withstand the extreme demands of professional drag racing. RPM modules must be purchased separately for rev limiter adjustment.
