Dry Ice Chamber

[Tracker]

My friend has two DSM. 91 and 92 TSi AWD. One he always is moding the 91 with his own hacked up ideas. Recently he built a chamber around his stock IC. He had to mount the IC differently and cut out the finder wall a bit. But anyway the chamber around the IC is multilayerd in the inside with Foam and something else I cant remember. But the top snaps off and you fill it up with dry ice. The IC get Very Cold. Didnt have anything to get an exact temp measurement but the HP gain was outstanding. He been talking about this idea for months before he did I thought he was nutts. He did say he spent weeks perfecting the chamber. Lots of time with the torch and stainless steel.


After 3 hours of driving IC was back to normal temp.(chamber empty)
You could feel the Hp lower as the IC got warmer.

Not sure if dry ice leaves any deposits behind after it evaporates but it would be B**** to take apart and clean out.


Good old Walmart sells dry ice in my town.

When I borrow my dads digital camera I will have some pics for those sceptics.

Interesting.

This is very similar to a "one-shot" air to water IC. It will work GREAT for short events like drag races and an autocross pass, but it's not as good an idea for a street driven car.

I'd be curious to see the picture. I don't want to make one, but it is interesting nonetheless.

Actaully I have seen some V8 boys do this. They ran a hose from there intake into a box filled with dry ice! the hose sucked up really cold air! seemed to work really good. Might be worth trying.

No kidin , sounds cool . Id like to see some pics if you get time to post a few.

that really cold air would be CO2....bad idea

I'd just run a full water/air IC setup if I was going to all the trouble of building a box around the IC in the first place.

Its not in the the IC its just cooling the IC. Its built around it so air still pass through the IC.

The air is still be blown from the Turbo through the IC witch is being kept cold from a sealed chamber around the IC. It works even better if you have after market lower/upper IC hoses that can also asorb the cold.


It not CO2 or the Engine would hardly run!

But putting dry ice in your IC would be bad.

I too thought of doing that very same thing. But I was concerned about putting dry ice into a sealed chamber. I thought the expansion of gases from the evaporation would casue the chamber to explode. I really have no clue if this would happen but that is what stopped me from doing this.
Also, is there any kind of smoke trail from the CO2 or anything as it evaporates? I don't think the track would like that very much, having a car plum out smoke as it goes dwon the track? clear this up for me if you can.

This is a very good point.

The lid is designed to fit air tight. But there is a hinged door(1/2in x 3in) with a 1/8 drilled hole(safety precation) to let the gas escape. As the pressure build the trap door will open.

If the door got stuck or blocked would make a mess for sure. Put some dry ice in a soda bottle and see what happens.

I was going to post something I observed last night but you got a head of me:

Last night we filled the chamber. While driving the fans and the wind disapate all the gas from the engine. A friend following us didnt see anything but when we pulled into the gas station and hung out a bit it started to look like a fog machine was in the engine. (not that bad)

He might be able to but a hose that would suck any gas out and devert it to the exhaust. Shouldnt be that hard.

thanks for the thoughts (ILOSE). They were very important ones!

Picked up the digital camera tonight. As soon as I can help James(my friend) we will take it off and get some close up pics as well as some after the installation.
I am trying to get him to draw up some blue print to post.
I also want him to add a temp. gauge and pressure gauge incase the hinged door where to freeze shut. That would really suck.
