If I can I will run the ITA car in EP at Lime Rock for laughs. [/b]
You'll probably do better as ITA cars routinley run faster times than the EP regional guys....for the most part. Certainly you'll get a better trophy.

Keep in mind that there are differences between the categories that affect the classing, so while it might appear that the car should parallel another ITA car, it might not make sense once you factor in the allowable mods.

For example, lots of ITA cars are 1.6 litres, but the Neon is much larger. (20%) Something is restraining that power, and perhaps it can be changed in Prod, where it coudn't be in IT.

Of course, on the other hand, IT uses a mostly mathmatical process to create repeatable classing, while the Prod guys use on track performace and intuition.
