It's an experiment. It's pretty neat I am getting heat of the hood and engine at the same time I am drawing outside air going around the scoop into the back side of the scoop. It is cooler than when it was right on top of the manifold Hot Air injected. But it is warmer than when it was Cold Air injected. I have done both of those experiments. The areodynamics are interesting as I drove it in the rain and watched the water pattern. It was even all over the cowling and the rain was even on the windshield. I will run it awhile and see how it goes.
