CryO2 Intake Cooling System
CryO2 Intake Cooling System Have you guys seen this before?

Does it work? Anybody tried it on an LS1?

same concept as N2O
i dont see a point in it really
and the only thing interesting they said was "Dyno testing showed a reduction in intake air temperature of more than 35%"
doesnt sound like it has advantages over nitrous, to me
maybe im wrong

From what I saw, it used the CO2 to cool the object that goes in the airstream. No CO2 would actually enter the engine.
Personnally, I don't see this thing doing much but being a huge intake restriction.

And Nitrous does so much more then cool the intake charge. Cooling the intake charge in most applications is simply a bonus effect as opposed to the primary goal (turbo and SC applications being the primary exceptions)
The CO2 intercooler injection setup has more potential then water injection as well. Downside being water is so much more available then CO2.
For the most part, these look like Ricer kits to me. They're more about cool sounding concepts then practical real world results most of the time anyways.
Just a thought...... twin-filter Volant intake with 2 CryO2 units stuck in each end...... LOL!
Whether or not this thing works, I like the concept. Design Engineering should add another functional option to the set-up, Fire Extinguisher!

uh... guys if you read the link, this blows CO2 over an INTERCOOLER, this is intended for BOOST applications where and INTERCOOLER is used. Kinda like blowing N20 over the intercooler... the liquid's expansion to a gas releases heat, the cool gas is then blown over the fins of an INTERCOOLER, NOT into the intake.
The fuel bar there is the same theory, the CO2 is circulated AROUND the fuel line in that fuel bar.
Thank you drive through.

Using C02 or Nitrous on the face of an air/air intercooler does work. NX makes a kit too.
Every 10 degree drop allows you to run 1 less point of octane.
I have thought about using a C02 kit on my blown setup but it's a bit premature for me to try stuff like that.

Blane, on that web page is both a intercooler spraybar and a cryogenic air intake (with the aforementioned bulb) that can be used for NA applications.
"Can be used on tubocharged, supercharged or naturally aspirated applications."
Thank you, please pull BACK through and read again!
:p

:p haha My bad, when I brought the link up the fuel bar and intercooler spayer was at the top of the page, DOAH! Even so, no CO2 enters the intake tract, and in that case I agree that thing looks like a big restriction.

Web site says lowers air temp by "up to" 50F. Here I
see someone else saying 35%. I'd say that must be on
a Fahrenheit or Celsius basis, not absolute temp - and
absolute temp is what matters, gas-law-wise. -If- you
got the purported -50F, that would be a whopping +10%
as far as any charge densification. That's equilibrium,
by the way. Which matters.
In a dynamic situation, what also matters is the fluid
time-over-target to pick up / shed heat. At high flow
you're only going to get a fraction of that ultimate
cooling. I figured it once, the other way, for manifold
heat soak. You need an awful lot of area to make up
for nil time in contact with the intercooler you so
expensively chill.
I'd bet a small amount of money that you'd be better
off spraying ice water than CO2 (if the track would let
you). Way more heat capacity per volume. Way cheap
too.

We used C02 cooling on a car w/ a blower. Basically, there's a heat sink chunk of aluminum that the fuel can flow through in a channel next to a CO2 channel, plus an in-line sleeve that mounts in the cold air intake that C02 also flow through. A WOT switch activates a solenoid for the C02 to come on. It's all contained within hoses & the mentioned heat transfer parts & vents (exits) @ a location far away from the air intake. You don't want the C02 to get into the engine. It will cause the engine to stumble & miss. These C02 coolers do work well, especially on cars w/ forced induction.
