Would an intercooler setup on a 4D55 benefit from a fan shrouded onto the IC? I have one of these leftover from a scrapped motorcycle project:

3A, 1100 CFM claimed. The fan is reversible, push or pull. Maybe this in combination with WI would help keep EGTs down? Would be kinda trick if it was triggered by a certain EGT temp, no?
