Rick Jones gave me a tour of his Pro Stock trailer one time. There must have been 10 chunks lined up in there. I asked him why and he explained why they have to change ratios if the air density changes. Pro Stock is so sensitive. I prefer a class where you just build your car and go race. And have a good time.
