Water-Air vs Air-Air in Non-IC

[iskone]

Hi. I've got a line on a 90' for what appears to be a good deal, so I'm looking at an ic install. My main concern would be reducing iat and egt's with a second nod to reliability.

Any experience with water-air on hear over the long haul? I have read they are more effective and get cooler but nothing of the maintenance over the long haul. I'd think the install would be about the same amount of fab.

I made a post about a small on off of a mustang. I was going to mount it in line to the factory intercooler.

In the end I ended up not usin it.

I read the thread but didn't get too much out of it. Since I'd be non-ic anything I do will help, I wasn't planning to use the engine coolant to cool the ic. I'd like to know if claims that they are better than air-air have merit or if anybody has ran one.

I came to the conclusion that running a stand alone cooling system to an air to water cooler was not practical to work with or to run on a DD. It would have worked great with ice water at a drag race.
Being that u don't have an intercooler I would find a Power Stroke intercooler with metal tanks. I read where they work well.

I have been leaning towards a standard intercooler setup for reliability. I would still like to know more about water to air however.

my gut says your right and it would be easier to use the intercooler out of a second gen or a powerstroke.

I ran a cummins waterjacket aftercooler on my 90. It had it's own cooling system, pump and cooler. It worked great, it was set up so that the pump would run anytime there was more than 5 pounds of boost. The biggest problem with the factory cooler (other than cost) is you need to run specific injection lines because it consumes the entire space of the intake opening on the cylinder head. When used on industrial engines, the cooler is plumbed to the engine's cooling system.

If you are going to trailer and work the truck a water to air will get heat soacked. On my yellow truck it was fine as a daily driver because it never got heat soacked because there wasn't much load. The stock water to air using a remote 20 gallon water tank with an electric fan cooler was good for a 150deg drop in egt's.

Oh that's something that I haven't read. heats up on a tow would keep me away for sure I'm not planning to throw all the time but will use it for towing on some occasion.

I just read through the while 1st gen build up for dpm and since I come from a strictly n/a gas background I found it pretty helpfull, I'm now looking at a water/meth setup vs intercooled.

I've got an air to water IC on my truck, but I still haven't gotten any water going through it yet. (Other projects)

I found a thread that has a lot of good info, but I hope you're not afraid of any imports.

Here's a few pics of my setup, though it's been quite a while since I've taken any.

Here's my heat exchanger, it's an AC condensor out of a 95ish Chevy 1 ton with the sick.5 turbo. The blocks are ziptied/JB welded on for testing(that I haven't done), since the current condensor had a pinhole from an accident. A new one with welded blocks will be bought when I see it works correctly:



The general layout. Plan is to go from a very small reservoir to the pump, then the IC, then to the transmission heat exchanger which I don't need with the 'Rag, to the AC condensor, then back to another port on the reservoir:



My revervoir is just an old power steering reservoir from a Mack truck, with the top cut off and a radiator cap welded in it's place. I really just plan to use it to bleed air, but depending on how it works I may need something more.

I'll update my thread some more when I get time, with better pics, but the poor Dodge ain't geting much love this time of year.
