[DeTomaso] Moving ac condenser to front of car., no, don't.

Boyd, I think that it acts like the back of a station wagon where the rear window always gets dirty, sucking up air. When my Pantera gets dirty on long runs, it’s usually the nose and the back panel that get the most dirt, indicating that the shape of the car sucks up air.
Thanks for chiming in the ones that have moved condenser up front and have good A/C and engine cooling. So it can be done. Now we just need to hear from the thousands that have kept it in the back and have the same good A/C and engine cooling. I’m one, on two Panteras. So both positions can work.
Mvh/Regards

Emne: Re: [DeTomaso] Moving ac condenser to front of car., no, don't.
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?

I have great AC and have no issues with cooling.
One big pro it can work with no problems.
Another it cleans all that junk out of the rear of the car and looks great.
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 )

Boyd, allow me to paste in my earlier input on this. Nobody disagreed back then, that could of course be because they think I'm beyond repair... :-) Please read below...

It pops up once in a while: the idea of front mounted A/C. Before you spend the time and money (unless you’re 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 doesn’t help.
A/C:
1. 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. If cruising or going fast, the extra air flow from the car moving MIGHT give better A/C cooling. I’ve 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, it’s just working as designed
Engine cooling:
3. 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 “cons”, 1. and 3., and one maybe “pro”, 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".
