Corky has a side-by-side radiator/IC combo sitting on a shelf in the lobby of BEGI. It looks about the right size for a Miata, though I do not know its history. It might be interesting to know the story behind it.

That thread really doesn't show the benefit in all that work... I think it'd take a real scientific approach to prove that there's any greater advantage over the traditional approach. There's a lot of things that aren't immediately obvious when first considering it the setup. Most are immediately blinded by the advantage of direct exposure to both exchangers (or only having them covered by the condenser). But then you've introduced the IC to engine bay (header/turbo) heat exposure that it didn't have before (and so on).
If you have a dedicated fan and/or heat shield behind the IC it would more than make up for any engine heat sources.

Except that the heat shield would then prevent the flow of air from the exchangers past the header/turbo. So now what? Compressor housing heat soak and elevated intake temps? Then that means the IC is getting hotter air and thus the probability of resulting temps similar to the fmic... negating the advantage.

This is what I'm speaking of- w/o testing everything, changing one thing and seeing a positive result means nothing if you've changed five other thing negatively but fail to realize it.

Call them up and ask them. They are pretty friendly about that kind of thing.

oh, and mr. V - where did you say your condenser was? (and trash is not an option)

Grinder's Vmount has the condenser below the radiator. Lots of room to fit it. Or it could be level right in the middle of everything.

A/C is a must, that's why I sold my other Miata to buy one with A/C. Never missed it before I moved to Utah. The condensor can easily be moved around. I pretty much have everything for a nice V-mount setup if the side by side fails.

assuming this isnt a joke, doubling the length might be beneficial in terms of heat loss from the pipe.

I'm thinking about removing it in my car right now because it doesn't really work that well currently, and i think that if it were hot enough to need the AC, I'd rather drive something else.

Default here is the beginning of my side by side

The Radiator will be a Ron Davis triple core, the IC is a stock Mazda part......

^Ooooooohhhhh.... I see lotsa new parts (like motor)... and require lots more info on this setup. Don't forget to start a thread and post pics when this thing is complete.

yeah- it was a joke... if you're extending one, you're most likely shortening the other. But the shorter cold side pipe is probably the better option. I'm doing the same thing- but I'm running an oil cooler in that spot.

To add to that, the total piping length would be the same regardless of which side it's on. Whether it's the inlet or outlet piping that's longer, doesn't really make a difference.

That's one hell of a shop you got there. The car doesn't look half bad either. What's your ETA for being done with it..well having it driveable?
