no cool down between the FATS. As soon as you get down to around 45 mph from the first FATS you start a second FATS. From a practical stand point it makes the data collecting riskier, and doesn't simulate a real world scenario. It does have the benefit of stressing the intercoolers more, but if you break it down into what it is, a FATS run, followed by a FATS run with the intercoolers beginning at a slightly higher temperature, I don't believe we would have learned that much more about the intercoolers. We could have accomplished a similar effect by idling on the side of the road allowing the IC's to heat up and then doing the FATS. The only thing that is changing is the temperature the IC starts at.
More information is always nice to have, and mulitple non-stop FATS would have been something nice to do, but we could sit around an concoct all sorts of tests that would have involved different procedures but little additional knowledge.
I'm open to hearing other ideas, there might be a good suggestion that somebody in the future can try. I'm still content that the tests that were done are quite valuable.
