First off I know a rad is aheat exchanger but in the world of racing we speak of rads as rads and heat exchangers as a rad with another rad, or "heat exchanger", built into the rad. The main part of the rad cools the water and the second is for the oil which is then cooled by the fact that the water passages and oil passages are side by side. This is much more effective on the oil cooling than just a plain oil cooler, or just a rad for the oil only. There are other benefits to running heat exchangers but that's another story.
Here's some examples of what I'm talking about-
Fluidyne Heat Exchangers
What I have been thinking of trying for some time now is using a small version (one for a shifter kart which would be about 2 1/2 time the size of a large HC) to use in water cooling. What I want to do is use the main part of the rad to cool the water going to the blocks. The second part I would run a seperate loop to, from the pump and back to the res. A seperate pump and completely seperate loop altogether would work best but space is a factor.
Since I do not have all the formulas necessary to do the appropriate math here I'm wondering if you guys think this would be worth the effort to try this. What about flow rate to run for each loop? I'm thinking that maybe each loop should run at differing rates. for pumps I have a Mag3 as well as a MCP600. I also have MCP 300 I'm considering using to make that second loop seperate if I can find space for it.
Thanks for any advice or smack in the head I may get
