TUESDAY TECH QUESTION 9/4/2018

Question:  I have a Super Pro Dragster that I recently purchased and I’m getting it ready to race at my local NHRA track.  Looking at the ignition box it has an MSD 7531 is this legal?

 

Answer:  No, in the 2018 NHRA Rulebook, Section 21, page 37, ignition, it reads ”The use of any programmable multi-point rev limiter and or a rate of acceleration rpm limiter, either by themselves (e.g.., MSD 7561, MSD 7761) or integrated into the ignition system (e.g., MSD 7531), is prohibited in NHRA competition.”
