An OEM pump is probably a 40 degree difference through the bricks of a 2650/3.0 since the pump is undersized. Real data will help us nail this down.  |
I am not sure going with a pump that moves the water faster or with more pressure will help. It is this reason I designed the system I did with large end tanks and not short welded sides, to help slow the water flow so it would reject more BTUs while in the main SCHX. I also made it stay there by using a bypass method which keeps the fluid in the one area and helps with removal of any air bubbles before it goes to the Driver's Side AuxHX and ultimately up to the SC.
The velocity of water molecules also increases the temperature by making those molecules move and become a gas, thus the more bubbles. In the world of HVAC, you are getting cooling by the slowing of a gas from one pressure to a lower one, thus that cools the air. Having the properly sized and flowpath HX makes this process happen and does so with greater efficiency and less air conversion.
