When Saturday night comes, you want to do more than win – you want to know the highest RPM you recorded during the race. For the greatest accuracy and smoothest action, you need to invest in an MSD Circle Track RPM Control.
Designed exclusively for GM-style HEI distributors on V8 engines, this high-quality rev limiter features an easy-to-read LED screen above two rotary dials, and offers an adjustable rev limit range of 3,000-9,900 RPM. Be aware, however, that should you lose the connection mid-race – or if it’s manipulated somehow – then you’ll lose all data and see a fault code instead.
Legal for emissions-controlled vehicles when used in accordance with the manufacturer’s app guide, your MSD Circle Track RPM Control carries a limited warranty.
