We decided to vent the 955 cubic inch (15L) Cummins engine compartment heat from the BulletTruck to a vent on top of the wheel well. I don't really have any good close-up pics, but these pics below should give you the idea. Underhood air temp ranged from 105F in the spring, to 165F in Denver on a 105F ambient summer day.
Not blatantly obvious from these photos is where we rolled-in the the front of the skirts right behind the steering tires. This was to speed up the air and blend with the expelled hot air from the engine compartment.
