In the original stock configuration does the AC suck air in to the rear
engine compartment or blow air out through the condenser? I always though
that the are dynamics of the car created a "Boundary layer around the car"
which created a vacuum or low pressure area around the back of the car.
That was why one needed elephant ears that really stuck out in order to
catch air for an air intake for the carb. When I set up my new ac I had two
fans and a larger surface area for both the condenser and the dual fans and
they blew air OUT through the condenser and out the vent in the back of the
car. It worked great. As I said I got cold air around 42F. maybe it would
have been colder if it sucked air in?

Assuming you need and new condensor and plan to replace those AC hoses
there isn't much difference in the price
And last it means I can have AC and 180 degree headers (coming soon )

It pops up once in a while: the idea of front mounted A/C. Before you
spend the time and money (unless youare rich and retired and needs to
get through the day), consider this:
It would have been easier and cheaper for DeTomaso to have the A/C in
the front, so why did they go to rear mounted? Very simply because
having two hot things close to one another doesnat help.
A/C:
1. A A A If going slow or standing still in stop and go traffic,
which would you rather have? A rear mounted no restrictions system is
for sure better than a front mounted where it would be sitting next to
a hot radiator and airflow would be restricted by having to pass
through both of them
2. A A A If cruising or going fast, the extra air flow from the car
moving MIGHT give better A/C cooling. Iave never seen figures to
document that, and my own rear mounted A/C deals with German/French
highways and stop and go in summer, without me having to turn the knob
to full cool, itas just working as designed
Engine cooling:
3. A A A Who would dispute that the risk of overheating the engine is
bigger when a hot restrictive A/C system is placed in front of the
radiator?
So what are the pros and cons? There are two definite aconsa, 1. and
3., and one maybe aproa, 2. Do the math, and save the time and money,
and spend it on getting the original system to work as designed. Be
cool

Emne: [DeTomaso] Moving ac condenser to front of car.
As some of you may recall I blew up my engine and was considering
installing a Coyote engine. As much as I think the Coyote is a great
engine I have decided to stick with a Cleveland. I have always wanted
180 degree headers and having just installed a super deluxe new AC stem
last year the prospect of moving the condenser and hoses to the front
of the car is the only thing that is standing in m way. When I upgraded
I installed a very thin parallel flow condenser . I was wondering how
much air flow restriction mooing the condenser to behind the radiator
will cause. I have a "True" lay down radiator and sucker fans. Is there
anything else I should worry about or take into consideration. I went 5
years with out having working AC and the new set up was blowing cold
air at 42F so I don't want to go back to the "Sauna".
