is anyone runnin an intercooler on there turbo truck with a/c?

Red3.slow

Are you looking to put one in and are wondering where to put it?

both actually

Me too.. You'll have to get creative. Clearly it wont fit behind the grill with AC.

I've seen a few in the wheel wells, but you really want it out in front with some air flow.

I am running an intercooler with my AirCon on my '94 turbocharged 22re. It took a lot of doing and some squeezing to get the plumbing to it, but if you were to go with some smaller diameter pipe it would be easier. I wish it was light outside, I would get you some pictures. I placed it between the frame rails up front under the fan shroud. I fabbed up a scoop that forms to the intercooler and it works great. The plumbling is hard to describe, I'll really have to get pics of it for you. I have a pic of it here on yotatech already, but its hard to see much. As far as performance goes... while I'm moving my intake temps are barely above ambient, even while under full boost. When The truck isnt rolling it doesnt flow any air through it so temps rise slightly, but fall back off while moving. Maybe an electric fan could fix that.

Dont mind the mess, its pretty aweful under there right now, needs some tlc


Let me know if you want more pics.

If you're getting ambient temps, that's outstanding. It's 70 degrees this morning and my intake temps are in the 160s.

Note the "stock" 22RE has intake temps in the 120s with 70 degrees ambient.

Have any sort of cold air intake?

How is the inlet temp of a stock 22re getting to 120 without a compressor?

dcg9381

Preheating from the engine compartment. Exhaust side of the motor is particularly hot in that area.

TC22RE

I should clarify some, my temps are never ambient, slightly above... generally about 10 - 20 degrees above, sometimes 30 or 35 depending on if its a really hot day. But these are all max boost temps. My intake isnt really a cold air intake, but I do have some vents cut to allow it to pull some cooler air from outside the engine compartment through the filter. I would say at 15psi on an 80 degree day I see intake temps of about 100. It varies some, but I've never seen over 130 degrees with the intercooler on.

The Lovely Boyo

Yup - it just that mine is a turbo diesel - easy mod and well worth it. Maybe this pic will give you some ideas to work with (1.5'' body lift gives loads of room under the hood)

tc

I think you should give me your truck so you don't have to worry yourself about it.

TC22RE

I've thought about moving mine over my engine like yours is Boyo. I just don't have an intercooler with the right inlet/outlet config at the moment... And since its working pretty well as-is I guess I'm too cheap to work out another install. Nice setup tho!

dcg9381

TC22RE,
Have any shots of your intake setup? I'd like to get ideas for dropping my intake temps that are still reasonable for wet conditions..

TC22RE

dcg9381,

I'm at work right now but when I get home if its not raining I'll take some shots for you and post em up here.

what do you guys think about air to water ICs? prolly a little better for space if you dont mind the extra components...lil better for cooling aswell for 4x4...

TC22RE

From what I understand about air/water intercoolers your intake temp is going to be the same as your coolant, so 180 - 190. Plus it still has to go somewhere...

Edit, or you could get creative and have a standalone coolant system hooked up to a cooler of some sort that circulates freezing coolant through the water/air intercooler... of course, I don't know if thats really feasible.

mkiidrifter

all the air-water ic's ive seen are running their own "standalone" fluid. hence why they are "better" than air-air...the only reason they arnt commonly used on turbocharged vehicle is cause weight.(pump, resivor, "rad" ect...) but on a 4x4 weight generally isnt an issue... cobras and other roots charged(modern) sc's generally have an air-water ic setup...they are worth looking into.

TC22RE

Ah ok, that still leaves us with the placement of the intercooler and the plumbing of the coolant to the standlaone radiator, and where to put it too... Seems simpler to install an air to air cooler. The only problem I've run into with mine being between the frame rails is clearance on descent angles offroading, if its too steep followed up by a sharp climb the scoop can catch the ground, its happened once... but the scoop easily unbolts leaving plenty of room. This may not be a problem with a lifted 4x4.

mkiidrifter

it just seems more what a slow crawler would need... plumbing wouldnt be too bad...just some 1/2" coolant lines...meh... the rad is more like an AC condensor...not so much a rad...

TC22RE

You may be able to fit the intercooler over the motor, and if the coolant radiator is thin it might fit behind the engine radiator, even with A/C. Keeping your intake temps nice and cool. But while doing slow crawling do you expect to hit boost, especially enough to really raise the intake temps? I do like the idea about placement tho. You can put the liquid/air intercooler just about anywhere out of the way and with a slim enough radiator it would fit on a truck with a/c. How efficient are liquid/air intercoolers?
