This may be a dumb question but here in my small town the race classes do not go my horsepower but displacement 380,440,500, 600,700,800,open. Last year they put the nytro in the open class i told them it was wrong but they would not change it. It was crazy a stock nytro in the open class with my supercharged attak plus a turbo just as well if they put the bravo in the 600 class. There are not many fx nytros around here but a town about 3 hours away from here they put the nytro in the 600 class seemed more right what do you think?
