[DeTomaso] CONDENSER UPGRADE - PHOTOS

[Mark Tumbarello]

Larry, Your static pressure (system off) means little other than you have 
something in the system. I would add some freon to push your low pressue 
towards the 35 psi level. I'm a little concerned about the low of 21, could 
be the begining of a clogged screen or fixed orifice tube. Have you washed 
the system or replaced those items? Your Temp readings sound great. The High 
reading 2.2 or 2.5 I believe to be average. I've seen suggestions all the 
way to 3x ambient air temp.  It's quite possible that your condensor is 
actually perfect for the Pantera. Mark
