3 main classes: 4 6 and 8 cylinder with a stock frame and big turbo sub class for each. So:
4 pot stock frame
4 pot Big Turbo

There will also be an Open class for anyone that doesn't fall within those classes and for everyone running NOS.
Prize allocation will be dependent on the individual class competition. I.e You wont get a big prize if you the only one in your class.
