So where can I find the rules about what equipment is needed

Both NHRA and IHRA have rulebooks that outline it pretty clearly. They are available online on their website. Another way is to go to the track and look around and ask questions.

I dont think i answered your question so here is my second try. On an 1/8th mile track I believe its 7.30 and 95mph but I am not 100% sure. On a 1/4 mile track its 11.50 and 120. I do know that for sure although some of the tracks near me aren't going by those rules and are adhering to the 11.99 120 rule.
