Just a thought on this and its possible way out in left field.
Would active cooling of the intake air on a non turbocharged/blown engine have any effect.
What I was envisioning was a cold box, similar to the fuel ones, but using peltiers on a cold sink rather than just filling it with ice.
Anyway just an idea. Its amazing what you think of while changing brake pads.
