too have constructed scoops to direct air into and through the
radiator in my '90 SP36. They stick out the sides 4 inches and are
painted to match. Look pretty but were of little help. I did not
use the ribbon test as I have a guage that measures inches of water
in both directions. When I attached a long hose to it and placed it
in various positions in the rear and side grills I found NO
measureable pressure. If anything the rear of the coach seems to be
a calm area with very little air movement/pressure. I have yet to
do the measure thing since the scoops were added.
Another thought worth considering is to install 12 volt cooling fans
on the side grills to suck air into and out through the radiator. As
you can tell I am trying to limit the amount the fan runs. I did
install a 180 deg. diverter (thermostat) in my 3208 but have not
taken it out with that change yet. Here's hoping!
