The question is this then.......If next year Toyota or Fontana wins more races than the Esslinger; do they then get limited on what they can do?

The V8-60,Offy,Sesco,VW,Cosworth,Pontiac, and Gearte all dominated the sport until they were replaced by something else. That is just how it is.

Why is it different now that it is the Esslinger?(A motor that has been around for more than a decade and is really the only company that has tried to find a way to fit into a budget for different levels of racers.)
