What are you guys using to keep ice from clogging up the water pickup at the cooler? do you have some sort of screen rigged up to keep the ice from being sucked into the hose leading to the AIC?
 
just run a length of pvc with rows of 5/16" holes, it will have good flow and keep the ice out
 
we run a screen about 3" from the bottom of the ice box to makea cooled water cavity it seem's to work great.

This is what we were planning on doing... What size screen are you using?
 
We ran an air to water intercooler all year last year.... and scheid dynod it with it this winter when they had are truck...There was no difference hardly at all between it and the spearco intercooler. The ice melted instantly just about so it didnt stay cold long enough to make a difference for us. Just alot of trouble at the track trying to keep ice.
 
what about dry ice??? im getting ready get six 4x8 sheets of diamond plate cheap and im thinking about having a ice box made for my drag truck.....im also thinking about building a fuel cooler.....

dry ice and water in a closed container will not end well. even with a vent its just gonna blow carbon dioxide out the vent. i dont even think you will cool the water before it melts.

nooooo....im not talking water and dry ice mix, oh i know it will blow, im just talking dry ice by itself, im thinking something along the lines of this ive drawn, i would obviously use round pipe with curves instead of this, but i think this would help, especially with dry ice packed around it.....the grey is the air and the blue is the ice obviously......and i wouldnt have that much in it, and i would make the top and bottom replaceable with some time of mesh or louvered metal so if you decided to run it on the street you could duct air through it and use it as a rudimentary intercooler instead of using dry ice.....i think i may build this at home and test it out on my 90 model......

NOW REMEMBER GUYS WITH WATER TO AIR INTERCOOLERS, YOU CAN ADD A BUNCH OF SALT TO THE WATER/ICE MIX AND CAUSE IT WILL SIGNIFICANTLY DROP THE WATER TEMP WITHOUT LETTING IT FREEZE...
 
ice alone wont do the job - you need a heat exchanger - and yes it makes a huge difference - 5-6 psi boost on our truck, and about 200 degrees less egt

like anything else the setup has to be done right, and just an ice box is a shortcut that doesnt work well or at all

salt will eat your aluminum

use a closed system with glycol cuz it works better than water, and then use a heat exhanger in an ice bucket

I agree 100%
 
Yea I wouldn't use salt water, it will eat aluminum fast. Just use anti freeze. The one thing to think about with dry ice, I think it is like -140. Could almost be too cold.

You guys spray water?? Im guessing you do. So for the guys that cant spray water, water/air is useless your saying??:umno: I run 2 of them and know many big trucks that do as well and say it made a huge difference. Every set up is different. Im not going to spray water so water/air is a must.
 
Talk about advantages, I help with a friends pulling tractor every once in awhile and heres some numbers we ran with ice/water to air intercooler...

(these numbers might not be exact but aren't far off...its been awhile)

The charged air before IC was around 550*, give or take some
The charged air after IC was aroun 150*, again give or take.

Obviously there is an advantage--cooler, denser air with more Oxygen per area of air (right???)

And everyone likes more multiple "O's"!! :hehe:
 
My truck's spoolup time went from anywhere between 30-50 seconds on the line with no Air/Water intercooler. Once I changed over to the air-water setup spoolup was about 10 seconds MAX in any temperature.

Truck ran a ton stronger as well, very happy with it.

This year I added a small aluminum radiator to the bed and went with a smaller cooler so I could move more weight forward. Should work well. Should also melt less ice too!

But what is the air temp with an Air to Air. I agree with Mr. Mosley that there is a bunch of pain in the but with an Air to Water.

I read somewhere that Diesel combustion engines run most efficiently with 58* F. inlet air temp. Can anyone confirm of deny that?

if i build mine im going to be using dry ice in it, cause you dont have to worry about buying ice after every run.....and if you do it right shouldnt dry ice last several hours or days if kept cool between use.....the stuff is cheap, its about $1 a pound......

i wondered about the salt water and aluminum after i posted that, dry ice starts to dissipate at -109* F. i think it should be enough to significantly cool the intake charge from the turbo to make a difference.....

how hot do you think the intake charge coming out of the turb on a non-intercooled VE cummins truck???
