Tuesday Tech Question presented by Evans Coolant




I’m in the process of building a Top Dragster and wanted to know if there are any ignition systems that are not legal”




There are two ignition systems that are not legal.  Per the 2018 NHRA Rulebook in General Regulations section 21, page 37, ignition, “The use of any programmable multi-point rev limiter and/or rate-of-acceleration rpm limiter, either by themselves (e.g., MSD 7561) or integrated into the ignition system (e.g., MSD 7531), are prohibited in NHRA competition.”
