[DeTomaso] Simple question on Condenser fan

[JDeRyke at aol.com]

The way Pantera rear airflow seems to work is, it sweeps up over the roof, 
far above the decklid, swirls around and comes back as a trailing vortex 
right under the rear bumper as a (relatively) high pressure area. The fan then 
sucks that pressurized air in, passes it thru the condenser and exhausts it 
down and out, under the car. It was a clever system, with limitations
As speed increases, the big swirl gets lower and more elongated until at 
around 120 mph, the swirl no longer approaches the rear bumper, which is where 
stock AC efficiency drops off radically. The poor AC fan is trying to pull 
air from a partial vacuum! This is where AC's blow hoses since the airflow 
is now almost zero and pressure rises. The stock system doesn't have an 
over-pressure cut-off switch.
As Tomas said, instead of trying to rework this guesswork-airflow with more 
guesswork to reverse things, simply move the condenser up to the front. 
Advantages: 
* the car's balance improves with 40 or so lbs less wt in back & more wt in 
front
* AC efficiency increases with speed, not the other way around.
All the same hoses fit the front mount condenser and radiator efficiency is 
not lowered (assuming the rad is working well to start with. A big aluminum 
rad should be there anyway). The condenser shroud & fan are not used and 
one can even use a thinner more efficient aluminum condenser of about the same 
length & width as the stocker.   It will cover about 1/2-2/3 of the 
radiator. And in the re-plumbing you can add an over-pressure switch, and the 
highly recommended   dual sucker fans can be wired to have the fan directly 
behind the condenser/radiator come on when the AC is turned on- like 99% of the 
other cars on the road today. Sure, its a lot of work, What ISN'T on a 
Pantera? Good luck- J DeRyke
