Actually, compressed CO2 has great cooling qualities. Sure, it can get sort of pricey, but if you're using it for say, Road Racing, or Drag racing, that could do a TON for intercooler temps, or even raw intake temps...

It gets the radiator pretty cold, but I haven't been able to run a test to see if it will make any noticable temp changes because I haven't figured out how to access the on board diagnostic digital read out. I've been told that you can get a digital read out of temp, oil pressure, speed, rpm, etc on the digital odometer display. Does any one know how to do this?

 

No its not always open. You must manually open the valve on the tank. Then you must arm the system via arming switch, and then a microswitch mounted on the throttle will activate the system when full throttle is reached, this vents liquid CO2 over the radiator. There is also a priming button which can be used to prefreeze the CO2 components before a race etc. I'll post a pic of the interior as soon as the switch I ordered arrives.

There is a short clip of the system on an SRT 4 if you just click on the link in my sig you can watch it.

 

hold in the odometer button when you start the car.... wait until it says something... i forget what... then let go

CO2 will freeze your antifreeze. its like -40 below or lower

 

its actually -109 F according to green valley chemical. so itll definatly freeze antifreeze or worse get your radiator so cold it burst

 

No, it wont freeze the coolant. Its kinda hard to tell from the pic but the sprayer is mounted an inch or so from the surface of the radiator, providing adequate room for the CO2 to expand. The sprayer is only covering about a 20 square inch surface area, relatively speaking, that is very small compared to the entire surface area of the entire radiator. Regardless of that fact, ethylene glycol and water, when mixed will create a freezing point depression, meaning that the freezing point of the mixture will be lower than that of the two individual components. Depending upon the molar percent of the mixture the freezing point can be much, much lower.

I appreciate the concern, but I know for a fact that it won't freeze the coolant, it would take a large amount of CO2, sprayed over a long period of time to bring a liquid, which is near 100C , to -60C ( the aprox freezing point of 60% (W/W) ethylene glycol/water mixture).

 

It's almost like an Intercooler Sprayer.

Does this model have a toggle switch?? All it'd really take is a few quick feathered hits, and the I/C would be ice cold..

Besides, ambient temps would be approx. +200F surface area when sprayed.

The only setback, is that our engines love running towards the hot-side of things...

our engines like cold intake tempts though... heat kills them.

 

what is better by the way? cry02 or alcohol injection?
