But like I said, we are out of my area of expertise. Some formulas would help. I would dig some up but I have an appointment in a few minutes.

Water enters the heat exchanger, the velocity of the fluid slows down due to the water being displaced over more area.
Water exits the heat exchanger, the velocity increases to previous velocity due to it returning to the same size piping that it was in when it entered the heat exchanger. There are some frictional losses there but we won't even go there.
This occurs any type of cooling sysytem that uses air to cool the water and it is grosely oversized like my design is.

So the idea is to keep the fluid in the radiator a long time and in the manifold or whatever the radix uses a short time. So if you wanted you could also get a larger pump that moves much more fluid to pull the heat off the manifold faster but the flow rate through the radiator would only be minimally increased due to its large size.

I pluged the radiator inlet and outlet with rubber expandable freeze plugs.

mj I am not sure if naked av is on the same question page as me, but all I am saying is you can spread something out over 30 pipes if you want, as long as it leaves the Hx in the same diameter hose it came in, theoretically you shouldn't effect the flow rate...enough to matter. Theoretically because eventually the weight of the fluid in front of the pump will become more resistant and that will slow the rate.
LOL this is kinda funny, we all seem to agree mj has something, but we disagree on it affecting the flow rate.

Hope you dont mind i quoted you in my sig, it just seemed so funny, and fitting, it described me and my situation so well.

MJHOWARD, I know exactly what you are talking about and it makes sense. It works the same as air flow. If you have X amount of air traveling through a area and you increase the area the air will slow down, if you decrease the area then the air will speed up. Jet engines have divergent and convergent ducts, convergent decreases the area and speeds up the air, divergent increases the area and slows down the air. Same principal as fluid dynamics. What you are stating is that when the water enters the radiator it will slow down do to the increase in volume, when it enters back into the lines the flow rate will resume standard flow.
Maybe this will explain it better for those who are a little lost..
