REFLECTOR: 2 Pass cooler

[Jim Agnew]

The standard Velocity oil cooler at cruise will give about a 15 degree drop.  This is based on a friends comments after many years of race car building and racing with similar coolers.  I would like to know if these are stacked coolers is the 20% drop from the first to last cooler or overall.  If there stacked then the second cooler is working with much warmer incoming air.
