On ApexSpeed.com I've been conducting a
survey of operational costs for each class.
Here I'm only looking at the predictable costs that
vary between the classes. I'm not trying to calculate total operational costs.
Some costs are more or less the same between classes, such as towing, hotel, food, entry fee, and so on. I am ignoring those costs.
Some costs are personal choice, and not inherent in the class, such as how much you choose to spend on your tow vehicle or RV, or paying people to support you. I am ignoring those too.
Some costs, while having some correlation to the class, are unpredictable and so difficult to quantify, such as crash repairs or engine failures. I am ignoring those too.
That leaves me with:
- tires
- engine rebuild (by a professional)
- gearbox rebuild
- fuel
- brake pads
- other, depending on the class
I guess there are other smaller but predictable maintenance costs, such as oil changes, brake rotors, brake fluid, etc. If you think the NP01 has above or below average expenses in these areas, let me know, and I will include them.
Drivers from many of the classes have responded with data for their class, and the result is:
a spreadsheet in Google docsHere's what I have for the NP01. If you have changes, please reply below, and I will update the spreadsheet.

Regarding the engine, here's the scenario: You have a fresh engine producing power that is competitive in a Majors race or the Run-offs. It produces this power for some amount of time, and then starts to fall off, and at some point is no longer competitive. You send the engine back to the builder, who does whatever is necessary for that particular engine (some classes more, some less) to make it competitive again. How much does the builder charge for this? And how many hours did the engine operate competitively before becoming non-competitive?
