Greetings folks.
I recently had an idea (perhaps of questionable merit, but I digress) for an alternative location for the oil coolers, as I would like to use the stock mounting location on the third gen for brake ducts should they need to be added in the future and also take the oil coolers out of the path of debris (i.e. rocks and the like). I have seen the use of FC oil coolers on turbocharged circuit FD's in Australia and New Zealand with (allegedly) satisfactory temperatures, but aside from that example and the one I have listed below, I have yet to see any similar solutions used in a third gen (likely due to packaging constraints of existing equipment).

I came across a design used by forum member 7dust, who had very a similar setup to what I am referring to on an FD that was campaigned in 24hr endurance events, and it is suggested that it worked very well.

Note how the oil cooler (believe I came from an FC) is placed behind the intercooler.

I would like to run the setup pictured below.


This would feature two oil coolers that are similar in size to those found on the FC. I have them laid flat in the drawing but can adjust the attitude so as to reduce the merge angle between the partition and the oil coolers if determined to be beneficial.

Aside from perhaps needing to place something in between the intercooler and oil coolers (perhaps a 0.125" sheet of mica?) to mitigate radiant heat transfer, I do not see why this could not work, but if you know otherwise, please do tell as to why. From what little understanding I have of airflow and aerodynamics, as long as I direct allof the air through the heat exchanger and have it exhaust to a (comparatively) low pressure area, air it should do what I wish to achieve. Am I correct in my assertions or am I misunderstanding?

Interested to hear your thoughts.

Why not just add ducts to your undertray and feed your brakes from that?

That was something I had thought about. I wasn't quite sure if there would be enough high pressure air under the car to do it effectively (or efficiently), but it's something I could probably measure with a differential pressure gauge. I figured I could exploit the high pressure area in the front bumper inlet but, it would probably be a good idea for me to take the time to try and quantify these things so I have a baseline to use as a frame of reference.

EDIT:
I did some looking on the internets and it looks like the NACA duct feeding brakes from the undertray can work. Some advise that it may reduce the efficacy of the splitter but I am unsure to what degree (if any). I'll have to go see how it could be packaged on a third gen.
