Kelly,

My guess is the A43-300 will provide about 30-35 F = Delta=20 T. My ECD54-329 (the largest unit) provides a maximum = 43F oil=20 temp drop. This is plumbed after the radiator using the coolest water. = It did=20 not do as well using warm water out of the = engine.

Chrissi,

I did not see an answer to your question = about=20 "Mocal" water to oil coolers...............It has been

reported previously that some have used the "Mocal" model A43-330 = cooler=20 with success........

Some have had custom units built by Ed Klepis at = "Tech=20 -Weld" or other suppliers........... I have

had a 330 for some time but alas I am still grounded=20 !!.............<:).........See PDF below..........

This is = where I=20 get confused:

said = previously,=20

-ideal = water temp=20 =3D 160*~180*F

-ideal = oil temp =3D=20 160*F

If we = are cooling=20 oil with water that is at best hotter than the ideal temp of the = oil, then=20 are we not adding heat to it rather than removing it?=20

If we = are trying=20 to cool oil, why would we feed the highest temp water to the = oil/water=20 cooler rather than the coolest temp water by tapping into the pump = housing=20 where it enters the block?

Based on = feedback,=20 the water entering the block may be as low as 150*~160*F, would this = be cool=20 enough to do an adequate job of cooling the = oil?

Also, = which model=20 of Mocal is being used?
