The cost of competing in NASCAR is a moving and high-priced target. The teams carry an inventory of 15 to 20 chassis. Part of the COT was to minimize this inventory but you can't keep the guys from spending money. The chassis specs are just liberal enough to make the bigger teams go after that last little bit of performance that is afforded by running all of the dimensions to the minimums and maximums, stacking them up one way or the other to give the maximum performance at a given track. There is much less variance with the new car but it is still there.

Engines are impressive for what they are, even though they are purpose built race engines they are still carburetted 2-valves. I guess that the biggest reason that they still use the carb is the expertise that exists in Charlotte NC around them. The other thing that NASCAR is very against is any type of electronic aide to the driver. They currently feel that the Fuel Injection could hide some Traction control in various ways and they view that as bad.
