At what RPM limit would you say the cost of building a motor really starts to make a jump? Not looking a F1 type stuff here, just for motors used for short track racing. Maybe there's more then one step but where are the point that component or build cost hit the next level.
You have to learn the rules of the game. And then you have to play better than anyone else.

Does it really matter? Not being a smart-ass seriously asking. I understand that the actual cost would be different depending on the rules. However I am mainly thinking that the cost jumps would be due to rotating assembly upgrades required, but I'm not an engine builder so I my be overlooking things that is why I asked. I was kind of thinking along the lines of up to X RPM stock components can be used, then at Y RPM you need extra machining and balancing, then at Z RPM you have to upgrade to high end components. I may be over simplifying.

To narrow it down what I am trying to use this info for at this time would be a stock iron block, iron head, stock car type motor. It would also be a dirt. Does the surface really matter if the engine is seeing the same RPM?

Then there would be 500 inch small blocks built. No way racers will go for cost control measures. We will kill the sport before that is allowed to happen.....
