I don't get why when using the manufacturer published cc you don't need to know about gearing, tire size, etc... and it just becomes an issue when you use the manufacturer published hp/torque. I don't think that any metric is perfect but on a stock car, the manufacturer published numbers (hp & weight) are likely to be more accurate than taking cc and applying some random factors for valves/turbo/type of gas/etc... especially with the current trend that delivers way more hp per cc.walterclark wrote: I think that in In U class - where engine modifications are not allowed at all - using engine displacement as the basic value to determine power, yields the largest performance discrepancies between same class cars.
Without doing a lot of study and a fair amount of math I dont know if using published HP and or torque numbers would be significantly better or not. Theoretically it should help with the issue of older models having less power:cc than newer ones. However defining power such that it is equitable from manufacturer published info may be difficult since to really get a good picture of it requires knowledge of the output across its operating range combined with gearing and tire size to predict how it would translate to acceleration. Who exactly would be responsible for developing this and ensuring it is correctly used for each car entered? I know who will not. The present tech team.
I guess the more fundamental question is why do you define classes for? If you look at the championship standings, there are only 3 classes with 3 drivers of more (P2, S1, S5), every other class has 0 to 2 championship eligible drivers. To me this is an indication that there are too many classes but on the other hand, people feel good at the end of the weekend when they finish first in their class even though they were the only competing after themselves (ask my wife!

To come back to the original point about drops, I would not drop a single event. If someone can make it to all the events, more power to him/her. This would avoid the discrepancies of having different events dropped for people in the same class.
