MSD Ignition MSD8251 Pro Power HVC Coil use w/MSD Ignition 7 Series 45000 volts

Give your racing machine maximum spark duration.

These HVC coils are designed for racing applications using an MSD 7, 8, or 10 series ignition. Due to their unique design, the Pro Power HVC coils are perfect for long duration racing events or on the street. A spark plug-style terminal is used to grip the secondary wire, and a Weathertight connector is supplied for a positive connection.

• Designed for racing applications with an MSD 7 Series Ignition Control
• Efficient E-core winding design produces more voltage and current
• 85:1 turns ratio and lower primary resistance produce high voltage output
• Windings are encased in red epoxy and secured with extruded brackets
• Spark plug style terminal and threaded brass primary studs
• Supplied with rubber shock mounts

Coils have always had to compromise voltage output against current output. More voltage increases the initial ionisation of the spark plug gap, but lowers the amount of current, or heat, that follows across the plug gap. When a coil is designed to produce more current, the voltage output generally suffers which taxes the ease of ionising the gap. The MSD HVC Coils are designed to produce maximum voltage and energy! To accomplish this combination of high voltage and current MSD uses an E-core winding design. T his n where less loss occurs during the transfer of electricity due to the closed core of the coil. Another benefit is that the coils run extremely cool, even at high racing rpm, thanks to the efficient design and huge laminations.
