    Cryogenics

    CryO2 Systems

    The CryO2 System is a revolutionary and award-wining performance product designed to reduce the air intake temperatures in the air/fuel charge. The result is a power creating alternative that is safer and cheaper to refill than nitrous.
    Through the science of aerodynamics and cryogenics, DEI has developed a system that harnesses the cryogenic properties of liquid Co2 to lower the air/fuel intake charge by up to 60%. The best part is that it is completely safe and unlike nitrous, CryO2 does not inject anything into your motor!

    We all know that the Northstar wants cold air.



    CryO2 Cryogenic Air Intake

    The CryO2 Air Intake segments mount right in the air stream using silicone sleeves. They consists of an aerodynamically designed bulb with a cryogenic chamber which is mounted in a 4" segment of air tube.

    Product Description
    The CryO2 Air Intake consists of an aerodynamically designed bulb with a cryogenic chamber which is mounted in a 4" segment of air tube. The air passes over the bulb, heat is removed from the air charge resulting in a colder, denser, more powerful charge. Dyno testing showed a reduction in intake air temperature of more than 50 degrees. The CryO2 Air Intake can be used on turbocharged, supercharged or naturally aspirated applications. Multiple units can be used for colder results. Installs in minutes and comes with silicone connection sleeve, hose clamps and connection / vent hose.

    Re: Cryogenics

    Operates exactly the same as using the shop CO2 extinguisher to cool a 6-pack in a bucket. Expanding CO2 is cold, so the little bulb in the airstream gets frosty.

    Who's gonna do the first N* dyno runs, before and after ??

    Re: Cryogenics

    "lower the air/fuel intake charge by up to 60%"

    How in the hell does it do that? That much reduction just by colder (i.e., denser) air alone? I guess I need to be enlightened.

    Re: Cryogenics

    How does the IAT sensor figure into this equation? Isn't it going to richen the fuel mixture?

    Re: Cryogenics

    Thanks. I see how it would help out with serious boosted applications. Maybe some blown 4.4L V people would be interested in this.

    Re: Cryogenics

    I am working on a cleaned up 99 intake. Externally cleaned up. I am looking at installing the bulb in the intake just behind the EGR plate.

    Re: Cryogenics

    AJ:

    How cold can the intake get for the N*? I thought people were getting good times with temps under 80 deg F. Is there an optimal intake temp? I have to hand it to you - that motor looks nice with the "redhead" cam covers. Are those the heads from last week that you purchased? Damn your fast...Nice drawings/picks too of the "legs". Hell, I could bring you some liquid nitrogen (-196 deg C) but I think carbon dioxide is safer (-78 deg C). Blown with the LS-1 PCM + cryo = pure insanity. I'm gonna lose my job if I keep on reading this forum. Isn't there plenty of room to wrap a long coil of tubing throughout that intake's runners from one end to the other like a reverse condenser? Keep up the good work!

    Re: Cryogenics

    Using their data of 50 degree F temperature reduction and this graph:

    http://www.ce.utexas.edu/prof/kinnas...S/densgif.html

    You go from 1.18 kg/m^3 to 1.3kg/m^3 (assuming 70F ambient)

    That is a 10% gain in density, which would give a 300hp northstar an extra 30hp with an addition of fuel.

    Thats not my intake. I borrowed the picture from a guy on the Fiero forum.
    My intake is well on it's way. I need to go back and cut out some more for the bulb.

    This is the Fiero that the Northstar is going in.
