You only need it if you are in the 9s. And some tracks at TNT won't care either way
This.
Running in the 10s, you are fine and don't need to worry about a license etc.
But the new rules are in effect. You can take your Demon, add better DRs, pulley, e85 etc and go run 9.50s and be fine.
I said when the Demon was being hyped up that it was a 10 flat car because the NHRA was not going to budge on their 9.99 rule.
But now you have barely modded ZL1s, Hellcats, Redeyes, GT500s, ZR1s, Z06s, Tesla Plaids etc all capable of dipping into that zone, that they needed to revaluate that decision.
