Most of us will not know better than mazda at some areas ...
But! It does not means we are wrong.
Like bse point out, there are obvious faults in rx8, some are just too "stupid" to call it a "oooops"
Look at fd for example, it was sooo obvious it had serious heat/air flow issues from day 1. But guess what mazda thought it will be ok and released it. Cars over heat left and right even when its completely stock and drives it regulary. And again it took mazda so many years to "see" the problem and released update on the later version.
Rx8 is having pretty much the same fate as the fd. Not as bad of course, but if mazda would spend maybe a bit more time into finding bugs/problems. Or just be like what software companies do ---- hire someone out there to test your car. That might not make sense for a car cuz u cant drive a car that has not been release publicly. Maybe hire someone out there and ask for their opinion and let them take it around or whatever. Not just go on fujispeedway or run around in nurburinging 20 times. When you mess up some product too many times, there will be no going back, look at the omp nozzle location, i have to say this i think mazda's engineers were smoking **** when they thought 2 nozzle pointing at the freaking corner would be enough.

It is just a simple idea.
It's true that cooling problems exist for this engine in certain circumstances and this simple idea may be of some use for some people.
In my part of the country where temps range from a low in the 20'sF to a high of well over a 100F the cooling system has to have a great degree of efficency. It is called on to keep the car hot enough when the ambient is in the 20's, yet cool enough when the ambient in in the 100's.
Thats not as easy to do as it may sound.
I usually have to "adjust" the system from winter to summer.
In order for a system to have a wide range of efficency it has to handle the heating/cooling requirements of the engine based on the thermostats range. This is more difficult in the rotary engine than a recip. Yet the cooling system of the rotary has the same basic design as a recip. IMHO that is a mistake.
I continue to believe that a single pass coolant flow would be better than the dual one we currently have.
Now what does all this have to do with the topic of the thread?
Just this. The most important factor in a engines cooling system design is the amount of face front of the heat exchanger ( radiator). The part that is first exposed to the cooling air. Yes there are many other important parts in this system and you can compensate for this or that within the system, but face front of the radiator is where it all begins.
Since we are somewhat space limited in what size radiator we can use, then common sense would say use the maxium of what you do have. Therefore my question.
Without moving the a/c condensor we are not using the maxium capacity of the cooling system.
I guess the next question is "what would it take to lay the a/c condensor flat on the under tray?"
Obviously the undertray has to be cut with a protective screen on the underside, maybe a fan installed on it for low speed operation, but I dont know about the lines? Anyone?
Actually with a fan it may even help with the a/c efficency during low speed driving?

You will need custom A/C lines made which are probably going to be a few hundred dollars each and a PIA to get right. It will require a pretty good fan and shroud setup that will probably stick up high enough that it will alter the air flow to the radiator, not to mention the air the fan is moving will be draw from the air supply to the radiator unless you are pulling the air from under the car toward the radiator.
I am sticking with my original conclusion that it is more effeciant (cooling, time and money) to install a large race radiator and or a secondary radiator then relocating the a/c condensor.

get rid of it, AC is for wussies 
some self locking tubing connectors and aluminum tubing should be able to extend the factory lines rather easily I would think
I agree a better radiator might make more sense, converting to a race car and ditching all the OE limitations might make more sense still

i know what you are thinking of. and i know sometimes just thinking or you have just run out of things to do.
what are you running for an intercooler right now, and whos radiator are you running?
beers

LOL--running out of things to do---you know there is probably some truth to that.
By the way I still have the meatball sticker you made for me!
I am running a much larger face front cooler for my a/w intercooler. It made a LOT of difference.
My cooling is ok. I just dont really like that a/c condensor where it is and I think the cooling system would be more responsive to the changing temps if it was moved.
I wish I could like Team says--just get rid of it all--but in Mid Ga---I dont think so.
