Ron Davis of Ron Davis Racing Products joins Kevin and Willie to celebrate 50 years of radiator evolution, from a $5,000 credit union loan to cooling the world’s most elite race teams. Drawing on decades of experience including NASCAR pits and the brutal world of Trophy Trucks, Ron explains application specific builds, the efficiency of straight-blade fans, and how custom-engineered shrouds with "road-race flaps" keep 1200HP monsters cool in the most extreme environments. Learn why thermal management is a "series of mistakes and learning curves" and how to properly spec a radiator system so you can finally stop chasing the steam and start chasing the finish line.
