Engine/Transmission (1994 - 1998) Marine aftercooler

[SDanos]

Has any one ever installed a marine aftercooler (heat exchanger) instead of an intercooler? I have a 86 f350 that I installed a 180hp (95) model with 40 over industrial pistons, industrial valve cam, 3K governor spring, modified cam plate, aftermarket compressor housing and wheel, and K&N intake. I have presently a 1st generation intercooler and due to clearance issues, it is the biggest I can put without Extensive front end mods. I believe I can stuff a marine aftercooler under the hood but I was wondering what kind of performace to expect compared to the small intercooler.

Ummm, where are you going to get a large supply of water to cool the charge?

You might also try a *gasp*Ford PSD intercooler. you can pick them up on Ebay pretty cheap. They are not quite as large as a 2nd gen dodge intercooler, but it may still work.



Oh, and technically, a heat exchanger between a compressor and a intake is an aftercooler, although improperly refered to by dodge (and pretty much everyone else) as an intercooler.

Yea, 180degree air isnt a desirable temp. You`d have to put an exchange tank in the bed and that aint happenin.

Cummins would tend to disagree with you, they had lots of air to water intercoolers on B series motors. They ran off the engine cooling "water"
The CPL 600 in my sig is set up that way.

yup school buses run the intake aftercooler with no problems. . a few others her have used them. . i have one my self from a marine lobster boat engine its run off the coolant... they had differnt versions the one i have has a small entrance hole for teh air . . teh school bus ones looked bigger. . I was going to modify mine. . i also got a grid heater that is teh full length of the intake plate... my friend said it was from a cat engine?... not sure about that but i was hoping to use that some time for more flow and a custom intake or the aftercooler etc. . the school busses etc have fuel injector lines that go around teh intake instead of over it to clear the aftercooler. . i hope this helps later

You too huh?



I can't spell "the" for the life of me when I type anything faster than "hunt&peck" speed.

Thank's apparently someone else is familiar enough with the marine and industrial engines that know that these style inter/aftercoolers run off of the engine coolant at 180-190 temps with no problems, What I was really interested is if any one had attempted this setup in a 3/4, 1 ton application and what kind of intake pressure response they had compared to an air to air style where the compressed air has to pressure up a whole intercooler system, including duct work, which is pretty extensive compared to a air to water exchanger, which is connected directly to the turbo and intake. I believe the response would be quicker, but I was wondering if the overall perfomance would not be as effective as the air to air. Ideally I would like to install the newer (larger) powerstroke or cummins intercoolers but I only have 1 inch between the firewall and back of the head @1 1/4 between the fan and radiator, and the backside of the grille already had to be cut down more than an inch to stuff the small intercooler behind it. To install the larger ones, I would basicaly have to change to a newer body style front clip with more clearence, but unfortunally I want to keep the older body intact. Thanks

I dont have any direct experience with the lag difference between a intercooled/non intercooled cummins, But I do know that it makes a fairly large difference on a gas motor.

you may want to talk to some 1st gen guys who had non-intercooled trucks originally that intercooled them and see what kind of lag they noticed from the larger volume of intake area that the intercooler added.

Im sure its noticeable, just not sure how much... .

Im not sure who but I know of one guy for sure running a marine aftercooler on his first gen. I think there might also me some others. try posting in the first gen forum and see what you get.

yes i have one installed on my first gen, alot i dont have it plumbed into the coolant system, It's a stand alone system with water tank and 12v pump. works very well when filled with ice water. But running it inline with the coolant syste would have to help.



if you have any questions feel free to contact me

SDanos... What truck do you have?. . if you have a early firstgen . . you can fit a 2nd gen intercooler behind th old grille if you cut it back . . i did it on mine. . i even flipped the intercooler upside down so the in and out pipping was up top. . ie easy to get too. . #ad

Zach, I'm looking into doing the same as you. I have the aftercooler and injection lines, but I'm wondering if there was some sort of tank/cooler I could use. Or would I have to build one? What capacity would be necessary? I know KTA has a transmission cooler mounted inline to help keep the water cooled. Where is the 12V pump located?

there are a lot of diffrent tank's out there you can use. I would just find a plastic tank to use like a 3-5 gallon plastic tank or fuel cell they are ready have fittings in them to run , but your looking around 100 bucks for a fuel cell that would work. The pump is just monted on the frame rail with a switch ran to the cab. I dont know how big of a hurry your in but my complete system less fuel lines will before sale shortly, im getting read of the aftercooler when I go with the twins.

I have it in a 86 ford with the smaller early 90's dodge intercooler, I already had to trim the ford grill to fit the small one so, there's no way the later ones would fit, I have a 94 dodge one from my donor truck, and it's just way to big unfortunatly.
