MSD 8145 Pro Mag 44 Electronic Points Box - Magneto Controller, No Rev Limiter, Red

The MSD 8145 Electronic Points Box is the dedicated magneto controller for the MSD Pro Mag 44 Amp generator, responsible for delivering the Pro Mag's signature long-duration spark and rapid rise time. The magnetic pickup inside the generator sends the trigger signal to the box, which instantly manages and releases the full power of the generator to the coil — replacing the limitations of traditional mechanical breaker points with precision electronic circuitry.

Once triggered, the coil produces a high-voltage surge to ionize the spark plug gap, followed immediately by sustained current flow across the plug for a full 26° of crankshaft rotation — ensuring thorough, complete combustion in even the most demanding nitromethane applications.

Key Features:

• Electronic circuitry replaces mechanical breaker points for instant, full-power coil triggering
• 26° spark duration across the plug for complete combustion
• Long-duration spark with quick rise time optimized for nitromethane fuel
• Heavy-duty cast aluminum housing serves as both a structural mounting base and an effective heat sink
• Humi-Seal compound coating protects all internal circuits against extreme vibration (rated to 300 mph environments)
• 4-pin Deutsch connectors lock and seal wiring connections to the Pro Mag generator
• Includes vibration mounts
• No rev limiter — for rev limiter functionality, see MSD PN 8147
• Sold individually; RPM modules must be purchased separately
• Racing use only — not legal for use on emissions-controlled vehicles

The MSD 8145 is the standard Electronic Points Box for the Pro Mag 44 system. It can be mounted in any orientation, provided it is kept clear of direct engine heat sources. For applications requiring rpm protection during driveline failure or wheel spin events, MSD also offers the PN 8147 version with integrated Soft Touch Rev Control circuitry. Not compatible with the MSD Pro Mag 12 or Pro Mag 20.
