PT Radiator Air Scoop
I hope you guys do the ribbon thing, kinda why I didnt post my
result.

I found that there is no airflow past the grill. the ribbon would
not lift horiz. mounted on aprox 6 inch a piece of plastic, the
ribbon would spin out and back to the rear. when the fan come on the
ribbon got sucked to the grill. I wanted to open the rear gate and
see if that changed air flow. But remember;is you only need the
engine oil to be 230 to 250 and the water 180 to 195 to make the bus
run as engineered. running cooler than that is not cool.

I do think that the hydrolic fan could do a better job of reusing
the radiator passed air to more evenly cool the outside of the
block. If you run the bus at 1500 rpm standing still ;fan on. most
of the air goes out the first 3 feet of the rear door vent and
verry little ever gets pathed to the battery area and manifold over
the passanger side engine block. I wonder if closing off most of the
leading part of the rear door vent would shroud the air to push heat
out of the engine compartment. I would think it would path air thru
the rad for those who have electric fans above the batteies.

shrouding engines for air cooling is an engineered calc. I think
that is where the gas workhorse pushers are having problems.

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!

PT Radiator Air Scoop

While this discussion has been going on I have been looking for an article I read about rear engine vehicles. Cooling was a concern because there is no way to get any "ram" air effect. The only radiator placement that had any benefit was rear mounted. There is a negative pressure immediately following a vehicle and there can be some passive air flow through a rear mounted radiator. It was not enough to "idle" the fan. I will keep looking, maybe I can find it yet. It did include wind tunnel tests.

PT Radiator Air Scoop
My main reason for airflow is my interest in adding a Mister. I
think the mister cools the air and not the radiator therefor you
need space and time to do the calorie thing to the air. My last
trip up the grapevine pulling a HummerPU in 105 degree heat and a
freshly rodded radiator proved that the cooling system works proper
the way BBengineeres designed it to.

The mister is just a project to add a safety device for backup as
there is a small variable between 'optimal operating temp' 185
and 'your totaly screwed temp' 205.

I like to run the dash ac but the fan need to be on to blow air over
the ac coil. It is not the added stress of the ac compressor that
engineers prompt the fan to run every time the ac is on, it is the
need for air over the ac coil. The prob with running the ac is I
dont like to run the fan as the bus water stays at 160 and the oil
way cool also.

a 12 volt fan should do the trick for the ac and even be an added
device to cool part of the bus rad. I wonder if some major 12v
airflow over the ac coil and one 12Vfan directing that air to be
exhusted over and out the grill at the driver side ; with closed
off rear vents is the ticket??

I dont think I will ever do it because sill havent taken down the
Christmass lights. gotta do that soon because they dont work and its
a litle over 100 day to go.

Gregg,

http://www.acpartsguys.com/ac_supplies
Check this web site, scroll down a little and look for the Hayden
High Performance Rapid Cool Radiator Mist System. $50 bucks. A couple
of these units with a few more nozzles would work. Mount it, wire it,
good to go. If there is no vacuum to pull it in you will need to spay
the water into the Rad some how.
