Heat exchangers

A friend of mine is about to put in a bigger heat exchanger. I was thinking of using his old exchanger together with mine hooked up together. Do you guys think this will work? Im pretty sure it will, but I would like to hear some opinions.

If you do this, make sure to split the flow and run them in parallel. If you run them in series, the second exchanger will have only a fraction of the effectiveness of the first.

A guy on the Florida boards has done this already(about 6 months ago). He placed the second one in front of the radiator (Tim, were you put your tranny cooler).
Try over there to see how it turned out. F L A . S V T


Hope this helps

You will gain volume by combining two heat exchangers.....this will act as an excellent temp. stabilizer....but I sincerely believe that a dual spal electric fan setup on your single exchanger will prove superior as far as quicker cool downs and temp. control......

I took the idea from the FL guy and have my stock heat exchanger in front of the AC condenser and the Fluidyne/JDM cooler with two spal fans in the stock location. They are mounted in series. I wouldn't mind comparing temperature data, but no one wants to post anything or can't figure out how to do it or just don't care. I have already started a few threads on this...

I was thinking of hooking up the other exchanger after the one it has. What ever heat the first one cant take out the second will.

Thats not necessarily true. First of all, adding an additional exchanger in a series will cut down on flow rate for starters. Secondly, location of the h/s will greatly affect its cooling abilities.

If you ran an exchanger in paralell, you now create a low pressure drop. This will increase the flow rate into the intercooler piece inside the blower. The question remains, will it affect overal cooling without increasing the flow rate of the intercooler pump as well. Until someone does tests based on this, we will never know.
