Welcome to the Dry Ice Intercooler website.

In the world of "Turbos and Superchargers" BIGGER seems to be better, at least for making horsepower. But as the saying goes,

" for every action there is an equal opposite reaction ". The "opposite reaction to bigger turbos and superchargers, is the cooling of more

and more air into the induction system.

Not to mention "lifting the head off the motor" which is controllable with other remedies,

I won't go into. I am addressing cooling of the additional air into the motor.

It is easy to bolt on a bigger turbo, but not too easy to cool the additional air it produces. So, a larger and larger

" AIR or LIQUID to AIR " Intercooler has been the norm, but space restrictions limit the size of the intercooler to the point,

that they become inefficient. My theory on this subject, is to utilize the same space you currently have,

but chill the intercooler more so that the same effect occurs.

Enter DRY ICE. Dry ice is a Negative -110 degrees.


Pellets work best in my intercoolers, because they encompass the intercooler tubes so that maximum cooling can be achieved.

Frozen carbon dioxide (CO2) is called dry ice. It is extremely cold and has the unusual feature that when dry ice melts

under normal conditions, it goes directly from the solid form to the CO2 gas. Dry ice will melt into a liquid under high pressure.

Dry ice is often used for handy refrigeration and for special-effects demonstrations.

Questions you may have include:

Q. How cold is dry ice?

A. Dry ice is frozen CO2 gas. The freezing temperature at normal sea level air pressure is -78.5 degrees C (-109.3 degrees F).

CAUTION: Although a block of dry ice looks relatively harmless, a person should use caution in handling the

material because of its extremely low temperature. It could easily cause frost burns on the skin.

ALWAYS Use safety gloves when handling dry ice.

Q. Why does it go from a solid to a gas?

A. At standard pressures and common temperatures, a material goes from a solid to liquid to gas. Water is a good example,

where it goes from steam to water to ice, as the temperature drops.

But at higher pressures, it is possible to skip the liquid phase altogether. The process of going directly from a solid to a gas is called

sublimation. Going the other direction from a gas to a solid is called deposition.


My dry Ice Intercoolers have a provision on top of the unit to "bleed off" the sublimated dry ice to the OUTSIDE of the vehicle,

in the same manor as a fuel cell vent.

Sublimented dry ice is CO2 gas, and will cause suffocation if not vented properly.


Another hazard is the fact that when dry ice melts, the result is carbon dioxide gas. Since CO2 gas is heavier than air, it settles to the bottom.

In some rare cases, it could cause suffocation.

Now you know the "Who, What , Where and Why, let's get on with it.

Dry Ice intercoolers are nothing new. Just Google the words "Dry Ice Intercooler" and you will see that not only are they feasable,

they are on some of the fastest forced induction cars in the WORLD, especially Austrailla.

Here are some of those examples:

Here is what I offer.

I am in San Antonio, Texas and I currently construct 2 types of Dry Ice Intercoolers.

These intercoolers are designed to go inside

the vehicle.

A large size $ 1,200.00 , And a small size $ 800.00 .


I usually have a Dry Ice Inter-cooler on E-Bay, for super cold air intake charging the induction of turbo or supercharged automobiles.

This unit ( the LARGE ONE in the photo ) will replace liquid to air inter coolers, pumps and lines with the same shape.

It features 4" in and out ports, and I will include the 2 new 4" aluminum band clamps. This entire unit weighs 30lbs.

( Most liquid to air units this size weigh 60 lbs ) This unit eliminates the possibility of liquid entering the intake air charge,

when the liquid to air core breaches, which often does happen on other types of units, when the metal expands and contracts.


This unit is designed to be packed with dry ice "pellets" and will cool the aluminum tubes to a negative -110 degrees.

It was also effective when regular ice was inserted in the chamber, but regular ice is only 32 degrees.

A drain bung is inserted for a drain cock.

Since dry ice sublimates, it is absolutely necessary to attach a vent line to the top of the unit and vent the sublimated dry ice to the outside of the vehicle,

in the same manner as a fuel cell vent.

I also have a unit that is smaller in size (see the photo) for 4 and 6 cylinder engines, and, is exactly the same shape with 2 1/2" in and out ports.

If you are interested in the smaller unit let me know.

As most people in this arena know that super cooling the intake charge will allow more "Air Molecules" into the engine, this will allow you to richen the fuel mixture,

and, in turn, will allow additional boost.

I have also made a provision in other units to run fuel through the unit to super cool the fuel temperature.

The tube you see here is to allow a connection for fuel to flow through the dry ice box, and cool the fuel to the carb or injector.

The tubing is 1/2 inch diameter OD, and is connected to 2ea # 10 AN fittings.
