I have a new turbo radiator in my car and it could not handle the oil cooler in front of it.
Remember, we run in 100+ temps out here. The factory setup worked just fine on STREET CARS, not cars that are now race cars. In addition, Germany does not see our kinds of temps either. Many Porsche's had trouble, in the past, with our American West temps. Porsche had to change their design specs as they sold more and more cars here.
Eric, thanks for going back to NASA on this one. It simply would not work for us "Hot Air" guys otherwise.
And for everyone, it is important to be open minded about rule proposals. Different regions have different issues/weather, etc. Some rules may not matter to most but are important to some. If they are not performance issues, try to be open to them even it they are not significant for your own personal car.
