Not sure about dry ice but everyone uses regular ice. I really don't think dry ice would cause any problems though.
That core looks really small. I went by CFM when looking for water to air units as the smaller spearco core only flows 400cfm so at wot and full boost on a T3 it woudn't be effective. It is prolly fine on that T25 though. I hve the next step up core, though it take more space, lol.

Water cooling is the sh*t. Way better than air cooling. Just ask any overclocker. BTW, my computer is water cooled. You should put more than one gallon of water. My computer uses a gallon. LOL. I'm using a 87 Chevette heater core and 2 fans to cool my water. Definitely add some alcohol or redline and some coolant because you will get algae unless you change the water a lot. Also, use distilled water.
Agreed, my unit will be 1 gallon in the tank, plus the water in the IC, lines and heat exchanger. I have like 2 bottles of water wetter on the shelf and will prolly a quart of coolant just to help keep the system clean and the impellers on the pump clean of gunk. Always use distilled water, whether it is the engine cooling system, water injection or water to air cooling.
The core may be small, but it is rated for 400hp. I had no intention of 400hp at first, but who knows what the future holds. Its a T28 btw Brent, pushing almost 300whp at 15psi with no cams. This is a daily driver, street driven, I always hate hearing air/water isn't meant for the street. As long as you have a big heat exchanger and a large resevoir it is fine.
I use probably closer to 2 gallons once the lines, core, and AC condensor are all filled up. Also, this resivoir can hold a complete 7lb. bag of ice. The ice works very well, I've seen similar results as unlucky, .2-.3 sec quicker ETs and +3mph traps.
I bought a Spa dual temp gauge and will be installing it for the dragstrip this season. It will be used for pre and post IC temps. That way I can get hard numbers to prove the effectiveness of an air/water intercooler.
Would there be any side effects to maybe puttin dry ice in your water tank?
That seems like a good idea.. Id try it out if i had a A2WIC, my grandfather was a chemistry and biology teacher, he said not too much dry ice because it would freeze the water if you put to much, and its a plus becaust it isnt really ice its carbondioxide.. Id try a little dry ice, coupled with some regular ice, like a 2:1 or 3:1 ratio of ice to dry ice. Thats what he said, he's a pretty smart guy. Seems like a great idea ***.
I'm pretty sure that dry ice and water form some type of acid that is not very good for the radiator and internal part of the IC.
Not only that but since this is a closed-circuit type of water system, I would think the CO2 in the water would cause massive pressures to build up. Isn't that the basis for CO2 bombs? Seal some CO2 in a tank of water real tight, and it'll eventually explode.
I'd just go with ice in there instead.
That's what I remember anyways from when I had my computer watercooled for a while...

Also, don't use alcohol. That can also have some adverse effects on the radiator and internals of the IC.
However, dry ice and alcohol might be okay together. I'll have to go look that up again as I don't remember for sure about putting the two together. Still probably not good though because of the massive pressures that would build up from the sublimating dry ice.
I'm going to be using an A/W setup for the street setup also. I am very confident that I will be able to keep the charge temps much cooler than a standard FMIC setup. I will be using a large PWR barrel style IC, with 2-4 gallons of water.
yeah, definetly NO dry ice, even with alcohol. the alcohol will not stop the dry ice from reacting with the water. the dry ice will blow that heat exchanger and related items to kingdom come, and as cool as it would be to watch, i wouldnt recommend it.
terrin drains his coolant every time he goes to the track too, though he tends to drain his through blown headgaskets.
on a side note, when i was in HS, my honors chem class had to perform chemical reactions for some kids at a local elementary school. i chose a dry ice bomb for mine. the kids loved it, though the mailboxes and other things were strangely blowing up quite frequently around my neighborhood (i lived right next to that elementary school) without burn marks on them, the only thing left behind was some plastic. strange....
you have to remember that dry ice is just carbon dioxide in a frozen state, and it will expand when it comes in contact with water. expansion in a sealed system like that w/o some kind of relief would be a bad thing.

Another old thread makes a come back.
Before I checked the start date, I was reading the beginning of this thread like, "didn't he install an air to water IC a long time ago?
I have a pwr barrel 4x10in core, a jabsco pump and a 3 gal fuel cell in the trunk. I have a decent sized trans cooler for a heat exchanger.
It works well, i have water and 2 bottles of water wetter in the system.
I would think the dry ice would work as long as the system is vented, i want to try it one of these days, just a small amount of dry ice.
Just with water and ice the intercooler is like frozen. I use a full 7lb bag of ice in the fuel cell. Auto-xing on a 80+ deg. day the ice lasts for a couple of hours. I have yet to go to the strip with the new water to air set up.
Later,Jon

As soon as i can get my camera to let me dump my pics onto my computer i will have some pics up and let everyone know what works and what doesnt, and how i set everything up.
Hey myprojectB13, where did you get that spa dual temp gauge and how much was it?
I'm pretty sure that dry ice and water form some type of acid that is not very good for the radiator and internal part of the IC.

it would most likely get too cold for decent fuel vapourisation, also the acid is only soda water, when it warms up it would boil out, so not a problem, but the pressure of all that boiling Co2 would be an issue. Dry ice and acetone ends up being almost as cold as liquid nitrogen, definitely too cold for gasoline, it would be rather slushy at those temps. Themal shock/stresses on the turbo would be interesting too.
I bought a 4 gallon fuel cell from Summit Racing, the more water the better as it can absorb more heat over a longer amount of time. This was about $70 shipped or so but you can go to a smaller 2 gal. unit if you want to save a few bucks, I don't recommend it. I also recommend trunk mounting this so you get more water in the system due to extra lines, you don't want heatsoak from engine bay.
THE BEST place for an IC is a place called extreme machines. They are an ebay store and sell IC units on ebay all the time. I called them and they built me an IC that is twice the size of the one shown in this thread for only $420 shipped!! That is a great deal and it works AWESOME!
Get a Tru Cool brand trans/oil cooler from www.racerpartswholesale.com to pull heat out of the water. Something like $63 will get you the perfect size cooler for a system in our cars.
Next is the pump, and this is crucial! You have to get something that can run a long time and can run dry (in event of something leaking and water is lost). The best pump out there is the Jabsco 18510. http://www.ipspump.com/ order Jabsco Centri-puppy #18510-0020 from here. They are in Rhode Island but shipping isn't bad. Should be like $170 total.
Then you run 1/2" water lines to connect them all together!
