Circle Track racing ignition ruggedly built to withstand harsh racing environments and packed with features for racers and tech officials.

Superior design makes the 6CT Circle Track Ignition Control unit the most advanced and durable ignition to ever hit a circle track. Packed with legendary MSD Ignition power, the 6CT offers a slew of features. A large digital LED display makes it easier than ever to see the rev limiter setting when dialing it in using the laser etched rotary dials on the face of the unit. 

Rev limiting is controlled via microprocessor making it so smooth the chassis is virtually undisturbed when charging into turns. The rotary dials are also used to set cylinder select for 4, 6, and 8 cylinder engines, and to adjust the built-in start retard providing options of 0⁰, 10⁰ or 20⁰ of timing retard for quick starts. As an added bonus the LED display can be used as a live tach or will display your racecars battery voltage. The unit records the highest RPM your engine turned during the race which can be easily recalled on the LED display as well. 

The 6CT offers all this and more in an epoxy filled, cast aluminum housing to prevent damage to the circuit board.  Its rugged build make is ideal to handle the rigors of dirt track racing while its advanced digital control make it reliable for countless laps around the track.  It's finished off with a single sealed connector to keep wiring dry and tidy.
