I had a custom aluminum made for my Challenger street/strip car and painted it black for my stockish look. Sort of.... Came with Shroud and two Derale electric fans 2000 CFM each. One I turn on with overhead switch panel. The second fan kicks on from the Racepak above 180 degrees. And, I added -20 AN upper and lower weld bungs for my -20 hoses. It runs cooler than my more stock street cars on the street with over double the power.
