In an attempt to keep costs down and racing close, many dirt track racing sanctioning bodies across the country institute a mandatory rpm limit in several classes. MSD has been in close contact with many tracks over the years and thanks to their input, as well as that of the racers, we are excited to introduce an rpm limiter designed for the Saturday night racer!
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.
