MSD is excited to bring this HEI Rev Limiter to the circle track world. The MSD Digital Soft-Touch HEI Rev Limiter is designed to plug into nearly any HEI distributor and produces an accurate, smooth rev limiting action. The rpm limit is adjustable from 3,000 – 9,900 rpm via two rotary dials with an easy-to-view LED to display the value. A unique feature of the this Limiter is its ability to record the highest rpm reached during a race. This is useful information for the race team, as well as tech officials. Also, if the Limiter loses any connection or is manipulated during a race a fault code will be displayed. The Limiter is encased in epoxy for protection against the abuse of dirt track racing.

It features fully digital operation allowing for extra smooth and accurate rev limiting to within a quarter percent of the set value, while eliminating the need for plug-in RPM modules, as convenient adjustable rotary dial’s take their place. 


  • A bright LED display clearly indicates the set RPM rev limit
  • Easy plug-in wiring and connectors allow the unit to plug directly into any HEI-style distributor with no cutting or crimping of wires
  • 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 pre-determined 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
  • Approved for use in both IMCA and USRA!
