Who here has a Water to Air intercooler setup?
#23
Here's the one I ran back in the day. There is one reason I ran this setup with a turbo: it was cheap. I already had the parts from a supercharger kit I ran before. On a supercharged car it makes sense because of the throttled volume and idle issues with front mounts. On the turbo, it makes no sense in almost any scenario. I can tell you from experience that any decent air/air is lighter and massively more efficient. That being said, it worked great for me on the street, I never had any complaints about it. But I never would have done it if I wasn't building that whole kit myself on a very tight budget. I even still have the damn thing sitting on the shelf in the garage nearly 18 months after selling my NA.

That is the PWR 4x10.
PWR Performance Products | Barrels – Barbed Outlets
Keep in mind I was only running about 4 psi while I had that setup. I pulled it out before I finished setting up boost control. I spent a lot of time chasing leaks and rust on the cheap water tank cap and basically tossed it out of frustration.
Plus if you look at the flow area through the PWR, it's crap. Teenie holes for the air and they protrude beyond the separating wall.

Just judging the surface area, that is a tiny intercooler and probably has a huge pressure drop across the two sides. If one was to use four or five of them and then a very large water to air heat exchanger in front of the radiator then things would possibly work as well as an air to air unit. But it would have a much greater expense, weight, level of complexity, all those hoses, etc.
Please also notice the Stillen unit is not oriented in the same way as the AWR unit, either. The Stillen unit has the air entering the wide end of the exchanger and not the narrow end of the unit.
By the way, a friend of a friend named Dominic blew up his VQ35 350z with that complete Stillen kit because it did such a bad job preventing detonation. You should definitely copy it.

I should mention that this wasn't my first air/water setup.
I had one of these:
Still a tiny intercooler. The later rally spec cars had a much larger charge-side core.
STILL...
a lot of people would ditch them for 6 feet of pipe to a FMIC.

That's what I did. Sometimes the process of doing a thing that is unpopular or against the dogma is worth the effort and the results, no matter how unflattering, are their own reward.

Water to Air intercoolers have their place in the car industry and can work well if designed properly. While I have not decided what is my best avenue, all I know is that can fabricate amazing parts, and so at the moment I joined this website to see what has been done and can be done that would be efficient enough at the same time save weight and remove my present intercooler which is located in front of radiator.
Look at this set up.
