Doubt it cole. We have no room in that spot.

 

Would it not be possible to just throw dry ice in an extra coolant resevoir??

 

lawlz at all the people thinking it'll make you go lean

this is dry ice in water thats the reason why u need to seperate the 2

 

Dry ice in water evaps so quickly it makes the water boil. But let me explain.
The water "boiling" is not hot. The reason the water boils is because the dry ice is evaporating CO2 so quick it pushes the water out of the way as it rises. Thus the water "boils".
This doesn't make it hot because if you took a temp gauge to the water you would see it is cooling super fast.

Now the reason we don't drop dry ice in our coolant tanks is because that release of CO2 (A gas) in the pressuried system means you have air (gas) in the system which as anyone who's done an H/E install can tell you is bad.


The more you Know...................(do do doooo doooooo)

 

sublimes actually, going straight from solid to gas.

I'd even try pouring an alcohol or other liquid in the dry ice chamber that wouldn't freeze, it would definitely help increase the surface area of cold for heat to transfer to.

 

well, if you're going to go off of the more you know...
The water in no way boils... that definitely would throw people off
The Dry ice (which is solid CO2) sublimates (it goes straight from a solid to a gas, instead of solid to liquid to gas). This gas bubbles up to the surface in the form of fog....simple as that.

BTW, you could put dry ice in an overflow tank in our cars because our HE coolant system is not a pressurized system (unlike our engine coolant, which is a pressurized system). This is why the HE coolant system has an overflow line and the engine coolant system does not. HOWEVER, you would not want to put dry ice into an overflow tank for our HE coolant systems unless you were ABSOLUTELY POSITIVE that the dry ice would not get sucked down the hose and leave the overflow tank. If it did, then the CO2 would build air pockets in your system, which would kill IAT2 temps.

 

if anyone would like some ideas for making a ice box... ive made one out of 1/16" aluminum.. tig welded to fit in common open spot for this... it is about 8" wide, about 6" deep, and about 3" tall...it has 2 hose barbs coming in front, a bleeder on the right side.. and i added a gauge on the right side as well... its pretty much 2 90* fittings on top and bottom of the box, with a clear tube to see how much is inside... on the top is a 3" filler neck to add coolant or when i goto the track, as much ice as will fill it up... i

ill try and get some pics tommarrow and post them

 

the dry ice goes an a sealed tube, which the coolant surrounds, if you ding dongs would use some commone sense, you would only realise that the dry ice is in its own reservoir, and therefore doesn't actually touch any of the coolant...

 

This correct. The dry ice box actually has its own heat exchanger core. On top of the core however the dry ice sits. IMO not really worth the hastle. The ice will have dissipated by the time you make it out of the staging lanes.

 

The pic of the redline is alphajags car and they only made 1 unit and they do not sell them anymore so he is the only one running one.

 

Dry ice would damage any plastic correct? I'm looking for a way to just cool the temps in between runs. Last track day, I threw some ice in the res., but my temps were already back up to 130-140 by the time I got up to stage.

 

uh ott sells a solution to this.http://www.ottperformance.com/Cobalt...duct_info.html

 

That won't benefit me. I have the extra coolant res. already.

 

^^^^^^^^^^^you got other issues then bra , im in florida too it aint that hot.

 

ha ha ha ha ha

 

Idk man. Cruising around and doing an interstate pull im right around 100-110..but just sitting 10 min in the stupid lanes it just stays at like 130-140

 

well you might want to get your fan settings changed the next time you get tuned...

 

Wow so much misunderstanding in this thread.... actually fail is a better term

1. The dry ice is in it's own sealed compartment that the coolant surrounds/flows around.
2. The tank is made for the cobalt and sits where the option B tank would go and its made of aluminum.
3. The windshield washer fluid tank is not obstructed and/or removed when you do this.
4. If the dry ice dissipates so what? You have now a modified option B tank that will still help with temps.
5. CO2 in the air intake...............

 

go easy on the noobs. hahaha

 

thanks max, for making it clear to the noobs

 

you gotta read what i said dude. The guy was asking if you could just put dry ice in an overflow tank. I explained all that was possible if you were to do that. I am WELL aware that this is not simply an overflow tank, and is indeed a whole new container that has two sealed systems. one for coolant and one for dry ice.

dont be underestimating my understanding

my list of problems like CO2 getting into the coolant tract were valid points if you id what the poser i quoted was saying and put dry ice directly into an overflow tank akin to hwta hatrickstu runs.

 

bump for more interest

 

ice box is finished, i havent updated this cuz iv been testing it since april. well it works nicely during driving (water temps are down 5-13*) but when the car is off the heat from motor tends to heat the box up, the solution is a heat sheild that bolts to the motor mount. il be finishing that soon. pics coming soon.
