Engine/Transmission (1994 - 1998) Air to water innercooler

[BrianHolbrook]

Hello, due to limeted space i was curios to see if I can use an air to water Water to Air Intercooler



like the one link above. I am putting a 5. 9 Cummins in a Hummer with solid Unimog axles and the axles make the frame go way up where you would normally put a vertical air to air innercoller and radiator. Any input on successful applications with air to water would be appreciated. I expect 400 HP and 700 FPT.

Thanks,

Brian

I can't speak from experience but those appear to be the same ones they sell on ebay. you might check The Turbo Forums.com for info.



I can tell you, if you buy that kit throw that pump in the trash or put it on ebay. bilge pumps are garbage and even the site itself mentions their less than stellar reliability. The fans prolly aint much better.



The core and radiator may be decent though.

Turbonetics makes a nice air to water IC pump, meant for exactly that.



Air to water works well for short spurts, but for long distance or duty cycle (run time between cooldown), they aren't the best. Once you heat soak the water/fluid, it's hard to cool it back down to where it works well again. Air/air has the advantage there.



If you're talking about a drag vehicle or something run for a relatively short period of time, the air/water works well because you can cool the water way down to almost freezing and get it to be really efficient.



We would plumb 55*F water into our air/water setup and even though intake temps were almost 500*F, outlet temps were right about 100*F... but the 8 gal tank would only keep it like that for a few minutes.

Pulling is one of the hardest things for an air to water. For the street or milding off roading or even drag racing, should suffice.

I dunno about anyone else, but I've never remained in boost for more than several seconds w/o backing off anyways.

Well, since this truck will be pulling for long distances what do you think of putting electric puller fans on the air to air innercooler? I can mount one at a 45 degree angle uneder the truck and fit two fans on the back.

What kind of speeds will this thing be towing at. Air/Air work well, but have to be in the airstream and need air flow to be efficient. The less airflow you have, the more area you need and yes, fans wouldn't be a bad idea as long as they don't impede airflow while moving.

you can run the water through an AC condenser as a heat exchanger
