Dual Oil coolers need to keep oil temps below 250F
during hot laps in the summer. Coolers are routed in
parallel for less pressure drop and better thermal
efficiency.  Road testing using various sized
"restrictors" at the outlets of each cooler and several
thermal couples resulted in a system that flowed
equal amounts of oil through each cooler with no
total system pressure drop.
