I know people pack Ice on the intake manifold when they make 1/4 mile runs to cut down the ET's but would this work? Putting dry ice in your air box then all the air your engine breaths will be getting cooled by the dry ice. Normal ice is 32F while dry ice is -109F I believe. Just a thought, would it work?

 

What is that stuff made of.. C02? I am sure people have tried something like this, and I am sure it doesn't work.

 

No way that would work! There's a reason they put ice on their air box and not in it. To put the ice anywhere where it would have a real cooling effect would block airflow or put it in danger of getting sucked into your engine. Even though it's just a gas I don't think it would be a good thing to get in your engine.

 

Actually I've heard of mustang guys doing this. The fill a pair of panty hose with ice and drop it in the airbox. They typically claim a before and after documented 1/10 gain from it.


EDIT: I wouldn; try it with dry ice tho, the extra CO2 won;t help power. Stick to regular ice.

Dry Ice = CO2. The engine wants Oxygen = O2. When dry ice is exposed to room temperature it "melts", well not really melts but it turns into CO2 gas. All that CO2 gas goes into your engine. The engine needs oxygen and fuel to combust. With all the CO2 in the chambers, the fuel won't have anything to react with = no combustion = no power + excess fuel spitting out exhaust or building up in chamber. It could also just shut off the engine.


I think?

 

The only thing I have seen dry ice used for was to cool gasonline. You take one of those fuel cool cans, add dry ice and a bit of alcohol. Instant cooled fuel....

cool can with dry ice and alcohol is great. chills the fuel well, cold fuel + hot cylinder = lotta power.

I have to agree with bottlepowder. we use a cool can on one of our race cars and it works awesome!!

 

what exactly do u guys mean by alcohol? like just poor some rubbing alcohol on the dry ice or what? i was thinking of running an intercooler on my N/A engine to see what kinda hp #'s i could get, but id like to try a cool can first cause its a heck of a lot cheaper. any chance running a cool can will help my engine when i run nitrous on it? like to help prevent detonation???

Carbon Dioxide is what they use to put out big fires and stuff. CO2 = fire extinguisher. Using dry ice in the same way as ice seems like a good idea though since it's colder.
