You are right Chris, it is a BIG deal! As Rickie points out in the article, unless the NHRA does something help the nitrous cars (reducing weight and/or increasing cubic inches), which they haven't, they will become a thing of the past in Pro Mod. And now with Rickie and Khalid running turbos, the only 2 nitrous cars left from last year are Chad Green and Bob Rahaim. Team Galot is now teaming up with Pro Line and Steve Petty, they are going to run Pro Chargers in their 2 cars in the Pro Boost class in the PDRA. I know that the NHRA is considering allowing them to run in 2020.
