So i've been thinking about Front radiator Formula Fords and I have two questions to pose. The first is this: Is it possible to build a crush box for a front radiator car?, and a related question. What if you reduced the size of the opening by using styrofoam or kevlar or some other crush type material, which would function as a crash box, And further you ducted the air in the remaining part of the opening( say with a 4 inch duct) to the radiator and then out by the normal route,( or via another 4 inch duct) Could you then reduce drag in any significant way?, and would the resulting temps be acceptable?
