El Paso, TX, May 27, 2014 MSD is excited to bring a NEW HEI Rev Limiter to the circle track world. The all new Circle Track RPM Control is designed for racers and tech officials alike. It’s fully digital operation allows for extra smooth and accurate rev limiting to within a quarter percent of the set value while eliminating the need for plugin RPM modules as convenient adjustable rotary dials take their place. A bright LED display clearly indicates the set into any HEI-style distributor with no cutting or crimping of wires. The new HEI Rev Limiter is epoxy-filled, making it resistant to the extreme conditions circle track racing presents including water, mud, engine fluids and of course vibration. The epoxy is also in place so that tampering with the internal circuitry becomes a thing of the past. New digital technology also allows the rev limiter to record the highest RPM the engine rev limited for a predetermined amount of time providing useful information to both race teams and tech officials. If for any reason the unit loses any connection during a race, the engine will lose power and set a fault code that will be displayed on the LED display.
