<VV> Air conditioning alteration

Thanks, Bob, but the whole point of the discussion is to not take up
trunk space.
We know that is a proven method, but it would sure be easier to keep it
all in the engine bay.
The guy with the LM who has it in the spare tire area is going to duct
fresh air from the diff/trans/heater box area, which should alleviate
his problem if the engine fan is truly sucking enough that it makes a
low pressure area on top of the engine by flowing it all for cooling.
That may exactly be why GM mounted the condensor directly over the
engine on earlies and where the air enters the compartment on the lates.

I think the best bet is to put it in the trunk.  I have done this on early
and late models and they work great.  I have a trunk mount in my '64 coupe,
running a Sanden compressor and a parallel flow condenser and a 15 " fan.
Using R134 and getting about 32 degrees at the vents,  turning 2000 RPM,
sitting in the shop.

chuck, I have found several long rectangular condensors will fit, I think
Clarks even sells one, my plan is to cut out a section of tin wiide enough
and on a slope so the liquid Freon can drain, add some 9 inch fans and blow
down into the wheel well.

I recently posted a question on doing this install, and a lm guy has a
running system that works when stopped, but not when driving, seems the flow
of air is stopped Across the condensor, maybe from ram air pressure in the
wheel well, or maybe the engine fan draws so much air there is not enough
for the condensor fans? A lm engine bay lid has a seal on it, our em lids do
not seal on 3/4 of it, so we may have a larger air supply available than a
lm.

Subject: <VV> Air conditioning alteration I am considering moving my1964
A/C condenser to my R/H Wheel well area.
If someone has done this what size condenser will fit that area and what
recommendations do you have.
  Is there a minimum size that the factory air system requires in Sq.
inches ?
