The MSD 6CT Circle Track Ignition Control is built for the rigors of dirt track racing in an epoxy-filled, cast aluminum housing that protects the circuit board. A large digital LE D display, paired with laser-etched rotary dials, makes it easy to dial in the rev limiter, cylinder select (4, 6, or 8-cylinder), and a built-in start retard of 0°, 10°, or 20° for quick, easy starts. Rev limiting is controlled via microprocessor for a smooth feel that won't upset the chassis charging into turns, and the LED display doubles as a live tach or battery voltage readout while recording the highest RPM turned during the race.Specifications: Compatibility: 4, 6, or 8-cylinder engines Voltage Required: 6-18V Maximum RPM: 12,000 Spark Energy: 135mJ w/ Blaster Coil, 150mJ w/ HVC Coil (PN 8250) Secondary Voltage: 45,000V Primary Voltage: 535-550V Current Draw: 0.8 amp per 1,000 RPM Weight/Size: 2.5 lbs, 7.89"L x 4.00"W x 1.87"H Color: Red Warranty: Manufacturer's Limited 1-Year Warranty Part Number: 6427 Compliance: This part is legal for sale and use on Racing Use Only Vehicles — competition vehicles that are not registered and never operated on the street.
