Reply to "Need input from IM owners"

Ed, it has been shown/proven that the twin grilles on a Spyder without an undertray EXHAUST hot air, not intake cool air. You know, with the old pieces of yarn taped on trick. Without an undertray, all cooling air comes from underneath.

I run a 96 plate cooler and fan because I have to. There is room for an internal cooler underneath the 911 shroud that I use. There is also no provision for flaps or thermostatic control of flaps for warmup. We end up with a pretty cold-blooded beast, but that ends up being OK when it's 75 ambient or above. It never overheats, not even on humid 95 degree days at Lime Rock Park.
