A little duct work that flows across a cooler and exhausts out of the wheel well would be pretty simple to fabricate. It could pick up its air below, or beside the radiator. The NASCAR round trackers have brake cooling ducts and other methods of directing airflow, so it's not rocket science to make air flow where it needs to go.
