Using dry ice with my w/a i/c

[MRKING]

I wanted to get some info from anyone who has used dry ice . I was thinking of a small container like this mounted in the engine bay.

I found they sell cheap dry ice by the pound , half a mile from my house . I dont plan on switching to a/a and I've been thinking of a way to *help* my w/a setup when at the track . Trying to stay away from the huge cooler with tons of ice and needless weight in the bed idea .This blue moroso box is another option as I fear the stainless will condensate and drip even though its a sealed container .

If I could put a 1or 2 lb chunk in either and make a run , then add another chunk when I run again , that would be alright . I could keep another small cooler for x amounts of dry ice to refill the front box when it evaporates . Yeah it seems like the cool can plus a second cooler filled with dry ice wouldnt be any better than the large ice chest , but the cool can weighs a couple pounds and the 2nd cooler filled with say 10-15 lb dry ice would only add up to a third of the weight of the big icebox method . I also know after I make a run or two on the icebox it would leave me a pool of hot water to dispose of , only to have to go get more crap loads of ice . The dry ice container when not in use , will not effect my intercooling system and seems like a good idea with minimal problems that I forsee

Anyone have any points to share , whether Good or Bad ? Used it , thinking about using it or what ever ..I searched and didnt find any documented results other than it evaporates and you will need more . I did find alot of people saying to use dry ice , but if thats reccommended for reasons other than people thinking it will work or not is beyond me .I also found a post from ed hess saying they got 2* temps at one point but it didnt last long on the tray he put on the top of i/c . I figured this was a diff approach and I could get some positive datalogged results when done . Thanks .

Re: Using dry ice with my w/a i/c

im no expert but id say give it a shot. The only prob I could see being potential is the coolant freezing and cracking a line. it may not happen while the coolant is flowing through the lines while the truck is warm but if the truck is sitting without running what ever coolant is in or near that chamber may freeze. but like I said im no expert

Re: Using dry ice with my w/a i/c

just make sure that if you do use it that the container is VERY well ventilated. When I was a kid, we would explode coke bottles with dry ice and water. Entertaining, but not something that I would like to have happen under my hood.

youtubed that sumbitch and found that kids still do it

Check the size of the inlets/outlets on those cool cans. Since they are usually made for fuel lines, I don't think they make them with 5/8" or 3/4" inlets/outlets. You're going to need something that will flow enough to make it worth while.

Re: Using dry ice with my w/a i/c

Both are sealed boxes , and both are also 3/8" line in/out . The 3/4" hose I use now will deffinately create an issue .

Back to the drawing board .

Re: Using dry ice with my w/a i/c

can you not just drill a small hole in the top of the metal one?

CO2 sublimes, so all you would get would be the gas venting to air. It isn't hazardous in any way. It would still do its job. Though without water in there anyway you would get very poor conduction unless it was powdered.

You could use reducers for the lines no? Flow is your only real issue - another inline pump?

Would venting an exhaust for the can underhood create a good deal of condensation with all of that heat?

I just made a thermal blanket for the upper ic, and threw a brick on top of the ic. Close up the top, and let it sit a while.

Saw 40 degree mats the first half of the first pass... degraded quickly after that.

Be warned... you gotta keep the coolant moving in that can if you use it. Dry ice will freeze even pure anti-freeze.

The real trick is to get a lot of cold liquid... like a cooler full. You need a large mass of cold coolant to keep the IC temps down. The liquid will heat quickly.

Cheaper than even the moroso box... Beer cooler with 2 heater cores in it, circulating the IC coolant. Set the dry ice on top of the cores.

Re: Using dry ice with my w/a i/c

I have been looking for a small round cooler , a little bigger than the stainless one above . I want to get 5/8 copper tubing and wind it around the inside of the cooler . So should I have some water or antifreeze in the cooler at all times to help transfer heat ? I may move my oil filter assembly and swap to braided lines , so I can fit this under the hood . Thinking about the venting or condensation issue , would a line running from the vent hole to back under the truck so it doesnt possibly drip under a tire work ?

Re: Using dry ice with my w/a i/c

After taking measurements under the hood , even if I moved some stuff , I am not going to get the space I wanted in the front corner. I was never really into the idea of cutting holes in the bed for a cooler or something like that . I know if I was to do it , the entire setup would have to look as good as it functions . I get alot of crap about my truck already from friends and family for it not being back on the road yet , and trying to explain "thats not a beer cooler , its a resevior for my intercooler " isnt a joke I want to frequent myself to .

Re: Using dry ice with my w/a i/c

Project is moving forward . I lucked into a large cooler at home depot , and it is what I envisioned in my head originally .

I have a few fittings to buy that will allow passage in/out of the cooler without leakage . I like the black and stainless and hopefully can find some cool looking straps to hold it in place . I've decided to drill 2 small holes in my bed and the copper coil is 5/8 by 10ft tubing .

Will my front jabsco pump be enough to move all my water through the extra 30ft ??

No that jabsco wont even be close to enough pump for your needs. Im doing something similar with my Ty, except im putting a 5 gallon fuel cell in the back for the tank and running -16 lines up to the ball valve, and running -12 lines under the hood from the front mount heat exchanger to the upper IC and pump, that way the front system is sealed for daily driving and the fuel cell will only be for use at the track, and im ust going to use ice water. But heres the pump i bought recently off ebay, flows 400 GPH, whichs is close to 6 GPM, so i figured that should provide plenty of flow.

Not sure why that pump won't work for you, but you can always use the ShurFlo pump. Designed to pump water in RV's, so I think it will be fine for your use.

Re: Using dry ice with my w/a i/c

I have a dry-ice / ice box in the bed of my SY. The IC lines run from the engine bay back to the bed, through a push IC pump to dual IC radiators, into another radiator inside of the ice box, back out into the dual IC radiators and out through another push IC pump to the front ATR Intercooler. I have not used it yet with ice or dry ice but was told it really wakes the SY up. If you need pics I can send them to your email or if someone would like to host them.

Jabsco/Johnson can barely pump water through the system as it is. They aren't designed to support a lot of system pressure.

The shurflo will have plenty pressure, and volume.

I ran clear tube in the crack between the bed and cab, and it worked fine. (I only intended it to be temporary) You might want to test your system this way before drilling, make sure you're getting what you want out of it.

You'll either need to use pellet-style dry ice, or have a conduction liquid in the tank. Glycol
will eventually freeze in dry ice. You will have to figure a way to vent it, as you will build a lot of pressure once the dry ice hits liquid and starts becoming CO2. (Can you say dry-ice bomb?)

This is kinda why the heater cores/ oil coolers worked better- you could set the brick of dry ice right on it, and get the mass of the core/cooler cold.

Heat transfer takes:
1) time
2) energy

The quicker you want it to cool, the more energy you have to remove. When you're talking about cooling incoming turbo air, you have a *huge* amount of energy to remove. This is where an air/air system gets its advantage... it has an even larger amount of heat capacity (the outside ambient air) than the incoming hot turbo air.

The people that have been successful at this have had 2 things going for them:

A relatively large amount of cold fluid.

Short 1/4 mile times.

(Note: Even Kevin Moore's Intracooler system- A/C cooled intercooler- worked by getting the metal mass of the upper IC cold, not direct cooling)

The laws of thermodynamics really govern this, and barring any active cooling devices (Freon, Peltier device), you're stuck with the mass/weight dilema.

Re: Using dry ice with my w/a i/c

I bought this pump off a member here and it will fit the bill nicely .

I got the cooler drilled and have 2 - 3/4" pipes coming out the bottom with threaded ends . I had to add a 2 foot section of 3/4" flexible copper tubing to the inside coil so the top of it could come out the bottom . Now the coil is 12 foot in length and I feel it should give enough surface area for the heat to be transferred out .The pumps going under the bed , I hope it isnt too noisy .I am going to use 3/4" heater hose from front to back . Where the lines come in through bed , I want to use a 18" section of ss braided so it all looks professionally done .The cooler's lid already has a vent hole , but its only a pin hole , how big should the hole be ? 1/4"??, 1/2"??
