So last time I was at the track the guy at the registration booth asked me if I knew what time I would be running and then if I knew about NHRA cert? Then he got distracted and that was the end of the conversation. Somebody told me I'd have to install certain things if I run faster then 11.50? I'm really really close and with the heads,cam and headers that I just picked up I'm guessing I'm gonna be below 11.50's. What all do I have to do to my car if I'm below 11.50? I have a snell helmet and drive shaft safety loop already. Any help would be great
