As thick a radiator as possible probably 5 core pipes thick. (3 to 3.5 inches) And as many core pipes and fins per inch as you can get!
A single deep nostril panel to allow as much air through as possible.and keep or away from the footwell area of the cockpit to help keep you cool.
Ultra high flow twin 12 inch puller fans, probably running 2500 plus cfm each.
An oil cooler radiator mounted behind the water radiator in the front of the car.
No aircon as the additional radiator would disrupt the airflow through the engine radiator.
Twin fans in the rear clip forcing air past the engine and exhaust towards the rear, I have 400 cfm per side.
Just a rough guess!
