Has anyone every fabd up a dual heat exchanger setup before? Looking to do 2 factory exchangers in place of the AC condensor and I want to know how this may out perform a dual pass single exchanger. 2 are obviously better but I'm curious if it's been done already.
Dual heat exchanger setup

A GT500 heat exchanger has been done and would be more efficient and have less plumbing. https://www.svtperformance.com/threads/installed-an-afco-gt500-heat-exchanger-in-car.1134584/
I've seen a number of people go to great lengths to shoehorn a large HE in front of their Cobra. Lot's of times that entails cutting-up the car which generally cannot be reversed and is something I am reluctant to do especially on this car.
The surface area of the IC in relationship to the HE is on a magnitude of ~ 2X on the factory HE and probably 3 - 4X with an aftermarket HE so it will be harder to get the IC to work more efficiently since a larger one won't fit inside the lower. I have lots of experience with liquid cooling electronics and have conducted test where at a certain point adding more cooling capacity on a system that doesn't get very hot to begin with starts to get diminishing returns and in a big way. The lower the temperature differential between ambient and the coolant temp the harder it will be to shed that last few degrees using a larger HE. Keep in mind the system only gets hot when in boost the other 99% of the time the coolant has time to recover.
My suggestion is to run the largest HE you can fit in the stock location and shroud (I used 1/16" thick sheet of kydex plastic which can be bent) and seal the lower grill opening eliminating the possibility of the air bypassing the HE ). I have a Gord's unit which is the largest HE that fits in the stock location I am aware of.
The other mod I like is the straight thru IC coolant outlet which should do a good job of reducing flow restrictions in the system. Other than that I wouldn't "over do" the intercooler system on this car it won't yield noticable results at the rear wheel over a well thought out system.

Russ,
All great points but I literally just about spit out my coffee reading this:
“entails cutting-up the car which generally cannot be reversed and is something I am reluctant to do”
Good recommendation for most but you are light years past this my friend...... for those that don’t know this is not a negative jab!

Troy I'll have you know I removed "zero" factory metal from the car.
I stand by my words!
Kinda sounds like overkill unless your going to be auto-xing or tracking the car where its gonna be getting driven hard for long periods of time and stay in boost doesn't seem necessary. There is plenty of ways to get temps down sitting in the pits if your drag racing. Other thing I remember that you really don't see much these days are the n-tercooler spray kits the imports used to use on FMICs might be something worth looking at too and probably cheaper and easier to fab. Watching and waiting.....lol
