Thinking of putting dry ice inside the Racing Cooler.



Everyone talks of "cracking something". Is this really even a possibility??

I have searched and searched and people talk about it (dry ice on blower) , but couldn't find one where someone actually did it.

Just an idea.... Either way, I am gonna try these things with frozen gel packs, but had the idea of dry ice inside them.

Thanks in advance for your input.

As long as the dry Ice is protected it will hold up well. It is of course difficult to handle and will melt rapidly. I would do a combo. A solid block of ice surrounded by a few chunks of dry works better for temp control. Ok my response to you is from years of experience working with Dry Ice in the Movie biz.. I have no clue about sitting it on the engine. I do know it lasts alot longer when it is combined with a block . It will also explode if the gasses are trapped so putting it in a little bag like pictured could be VERY DANGEROUS. We put it into cylinders and make bombs, I think you need a vented environ when exposing this to engine heat, so the gasses can escape. I know this likely did not help at all, Happy Sunday

Putting dry ice on top of your super charger may shrink the top half of the housing (could crack), remember that the rotors in the supercharger have a close tolerance between the housing and rotor 3-4 thou. If the housing shrinks enough the rotor could rub housing. What you are really after is to cool the compressed air in the exhaust side (underneath) of the super charger, so it may be better to try and super cool your intercoolers radiator.
The trick set up would be to wire your circulation pump (johnson) to run on its own switched circuit, with switch under hood. Then fab up a means to hold regular ice on top of your intercoolers radiator, I might use a basket that is formed from expanded aluminum that sits on top of IC radiator holds like 5 lbs of regular ice. that way you can pre-chill the entire system with out fear of thermo shock or distorting blower housing. use the dry ice to keep your regular ice frozen, byproduct cold beer.

Why not just use regular ice?

Yeah, probably will end up doing that. Just thought I could run it by you guys and see what you thought. In my mind, I am thinking "Aluminum will transfer the dry ice cold nicely straight down into that intercooler under the blower" , but wasn't even thinking about the shrinkage that would occur with that much cold on it. Perhaps this myth is BUSTED.

I have often thought of making a basket of sort to put in front of the intake tubes so the air going into the intake would be cold but didnt know if it would work. This is where the pros need to chime in and tell us if all this work would really help out or not.

Dry ice doesnt melt. It sublimates.

Why not setup a pre-cooler. That way the air coming into the intake is colder. I would probably start with thermal insulation of the intake tubes and then figure out a way to super-cool incoming air. A total loss evaporative heat exchange such as dry ice packing and anti-freeze cooling would work in my opinion.

Ice on metal is probably a bad idea.

I would just use regular ice...

I have made a fire-resistant pouch that takes gel inserts for that very reason.

It straps on with velcro to the top of the blower, so I can be left on during a run. I've even passed Tech with it.


Bottom line: Zilch.

On a boosted car, the diabatic heating from the mechanical compression of air rapidly overwhelms the (relatively) minor cooling benefits of the pouch.

On my previous car, it was worth a full tenth in the quarter, measurable and repeatable.

I've seen more effects by turning on the A/C to run the aux fans, lowering the water temp. This is just one indication of how marginal the cooling system can be in these cars.............

Then let's just go with LOX injection see how many revolutions it takes before the crankshaft comes out of the exhaust.

Sublimates rapido in heat. Great , thanks for the correction. Gosh I Love you guys

When I went to the track a couple times, I would take a bag or two of ice and let it sit on top of the blower inbetween runs...seems to be fine...

blackbenzz

I did the same thing. Leave the intercooler pump on for even better cooling.

Hi Guys, This is Wendy from Racingcoolers, The Gels that come with my coolers are non toxic, non corrossive, and come out of the feezer below zero temp,They can be handled ,unlike dry ice. I spent alot of time testing these gels , and they work perfectly,20 degree temp drop in 10 min, last all day into the night when rotated properly. First I have to tell you that dry ice is not legal in all states for use, it conforms itself after ten minutes because of its chemical compounds it will throw heat off... But will NOT absorb it,Racingcoolers absorb heat, this is key in removing hot air from the plenum. Dry Ice will also have a much better chance for cracking the intake due to aluminum shock. Well here is my site and a good article to read would be the Hot Rod magazine tech test. WWW.Racingcolers.comThanks Wendy, owner, designer, Racingcoolers.

So you're saying that solid carbon dioxide at negative 109 degrees will somehow suddenly heat up?

Physics class was not your friend.
