Hi everyone,
	I decided I did not like the cooling system mounting in the Limo EZ.  The 
scoop is too big and the resulting lower cowl is draggy.  Because this is a 
pusher I decided to design an inlet that starts half way between the 
firewall and the landing brake location and expands at 7 degrees until it 
reaches the rad and oil cooler.  They will be mounted vertical 
perpendicular to the air flow.  The duct is about 42" in length and is 
grater than 2.5 X the largest dimension of the rad/oilcooler area. I am 
using an exhaust augmenter maybe a version of the VAM pipe.  The problem is 
that I will have to use a small radiator and maybe the 93 oil cooler out of 
the car or an aviation cooler with the same volume but thicker.  For the 
rad, evaporator cores like the 81 Caprice vintage (342 cu inches) would 
fit.  I think that this system would work but do not have any experience 
with evaporator cores in pushers.  Another issue is getting sufficient 
clear area behind the rad.  Here is where a dry sump or short oil pan would 
really help.   Any thoughts on this?  Thanks for any help.
