So a 9x10.5x3.6 GM core turns out to be pretty close to what the equations
indicate in required for that power and airspeed. Actually perhaps a bit
thicker at 3.64 inch than optimum at 120 MPH according to the equations.
So
the 3" thick core could be a bit closer to optimum if using a GM type core
than the 3.6" core for 120MPH cooling and would probably improve cooling
in
the take-off and initial climb phase where there is less dynamic pressure
to
force air through the cores.
Hi, Ed....Do I understand correctly that only one of these cores would be
needed to cool 160 HP at 120 MPH? Thanks. Paul Conner
