Where's the best place to find an air to water cooler for our pickups? I'm guessing cummins would be best? What does the price on these things run? Thanks

If I understand you're qwuestions what you are looking for is an aftercooler, which you can find on marine app cummins engines... so, I'd say look where the boat parts are and you might find a good used one?

 

here's what i'd like to do to my non-ic truck

if you had some fab skills you could put something together. put a small radiator off a car up front with a 12v water pump and if you are worried about saturation then you could add a small tank that you could put extra volume or icy water for race or dyno days. tested to 80psi! plus, with this kind of setup you don't have to worry about water meth like i'd think you would with the cummins cooler pics that have been posted.

 

I had an air/water aftercooler (Vortech) on a 5.9L gasser Ram...

when the Vortech pump blew up, I replaced it with a 12V marine pump...

Vortech may make something that could work...

Dang Mark great idea, wish I'd thought about that.

Air to water can offer up to 86% effectivness if properly done. With ice at a track they can pull charge air below ambient air temp.

 

This may be too wacko to work, but I've often considered using A/C to cool intake air. Using an A/C unit but running coils of copper tube around the intake air tube to chill it seems like it might work. Don't know how the numbers would turn out in comparing parasitic drag of A/C compressor to cooled charge air benefits, but maybe a 12V electric motor to turn the compressor? Seems to me there's gotta be a way to come out ahead with A/C chilled intake air?

It's possible to use a switching valve so you could either have normal A/C in cab or chilled air for fun runs.

 

The Cummins air to water cooler mounts up on top of the manifold, the inlet points over towards the turbo. If you wanted to run it you would also need the injection lines.

 

Jimmy its not a goofy idea, its been tried and done but unless you build a dedicated system it wont work. The main reason is the freon, 12 or 135 isnt the best choice,its boiling temp is wrong. and a auto doesnt have a condenser any where large enough to disapate the heat.

Remember in fact an a/c doesnt really cool your car, an a/c in fact removes the heat and transfers it to the outside, with intercooler it take a very large condenser to even start.

But hey, just for fun ill do some math and see what i can come up with.

 

Interesting! So Evaporator coils could be wrapped and soldered [better heat transfer] around the air inlet tube for its entire length. These coils absorb latent heat from charge air tube and refrigerant is then pumped to the compressor intake side, and on to the condenser where it removes the heat absorbed at evaporator. Then on to a receiver/drier to be filtered and demoisturized and through a thermal expansion valve and back to the evaporator for another cycle.

With a much oversized intlet tube [to allow for volume lost to coils] the evaporator coils could be run into and through the tube allowing refrigerant to remove heat directly from the air, with the rest of the process being the same. Here the refrigerant coils could be done in a spiral coil down the length of the tube with air space on outside and inside of spiral to allow smooth passage of charge air. Hmmm...maybe my Cummins conversion will be getting an A/C compressor added.

 

Why not just put the evaperator in the air box .......or would there be to much air flow thru it to keep a cool air charge!

 

That's what I'm thinking: too much air flow. Seems like a spiraled coil of evaporator tubing down length of intake tube would allow more exposure time for the process of heat removal to work. The gas molecules in the air would have more and repeated contact to cool the charge air. I'm talking myself into doing this even as I hunt and peck...

 

wrap it around the out side or in side of the the tube?

sorry just realized that you talking about the intake or in let side of the turbo not the pressure or compressor side of the turbo!

 

The coils would need to be internal to get enough transfer rate.

 

Ya i now

I could have just deleated it before i hit the submit button but........well a guy got to be able to laughat him self before he can at any one's else's a.......Brain farts!

Just thought i would share this one
