First cool air is not faster it is infact denser and slower than hotair. But Air density is the secret to big hp.The reason we have intercoolers on our car is to cool the intake charge why cool it you ask? The main reason is to lower engine temps and the byproduct is horse power.Air when cooled becomes more dense compacting the oxygen atoms tight togeather thus delivering a potent dense charge to explode in the combustion chamber.the system your looking at looks like a viable option to help lower intake temps you question is what are the draw backs well tuning for the denser charge denser air has much more oxygen in it thus leaner so as long as you can supply the extra fuel for the increased oxygen then you will br fine .

Hey Travis, do you know what a metaphor is? Seriously, doesn't the air temp sensor that's downstream from the "air cooler" do the "tuning" for you in this instance?

The air temp sensor should not be down stream of the co2 because you will freeze it and posibly destroy it and also the span is not great enough for adeqite fuel compensation.I think just before the throttle body is the ideal spot.

Just got the medafor cold air is fast air(haha) boy am i slow.

CO2 should be ok to cool down the intercooler externally but it seems to be stupid to inject cold CO2 in the engine as it is unusefull for combustion it will just give the possibility to run lean and destroy the engine...

Russ Murphy

It sounds like there's some confusion relating to the inline charge cooler. The liquid CO2 is being sprayed into the bulb shaped container in the intake where it expands and cools the bulb surface and then is bled off external to the intake. There's no CO2 going into the intake or the motor.

Have overlook too quickly the system...
Sorry for my "stupid" previous post.

The biggest problem I see is the consumable nature of CO2. My guess is that a full tank would be short lived. Kind of like NOX. Fun while it lasts but.... Also this would be illegal for every racing Org. I can think of since it is a compressed gas cylander.

I have a top-mount Carrera GT style cooler on the top of my 931 engine. So that system will snap right onto the front of the cooler (the cryogenic chamber) and the sprayer up top is perfect to cool down the cooler at stop lights and low speeds, where the cooler is more like a heat sync.

I telephoned these guys and the story is right: Feb 2003 it'll be ready.

I'm buying one. No question.

When you talked to the guys at DEI did you get a sense of how long a 5lb tank would last?

You could design a cheaper system using a Nitrous Purge valve kit. They run for around 100 bucks.
Comes with the solenoid and everything ready to go.

Cooler intake air also helps to lower exaust temps in a 1 to 1 ratio, I believe

Hi Russ,

You asked "When you talked to the guys at DEI did you get a sense of how long a 5lb tank would last?" No I didn't. But I'll be talking to them this week and will bring that question to him. Thanks.

Hi Boostguy,

Could you? Wouldn't the cost of nitrous far exceed the cost of CO2?

BoostGuy951

BigPorscheGuy39-

I mean using a purge valve as a the sprayer nozzle, since it is designed for very cold gas and will not freeze. It comes with a solenoid and switch for the dash. It is pretty much all you need. I don't intend to use N20 as the cooling agent, CO2 is much colder and cheaper. But the kit doesnt know the difference.

BigPorscheGuy39

Ok I get ya. Thanks for the information. What I think I'll also ask this guy on the phone is just how the unit is switched on. Is it boost, or RPM, or speed, or what, that determines when the CO2 kicks on and off.

You know, when I've had a long day, and I'm a little foggy in the head, maybe not thinking straight, I get this odd urge to someday add nitrous to my system. You know, a little shot for a burst of horsepower in the lower RPM range.

Then I shake my head and imagine the sound "Boom" - and I hear this German voice saying "Ten sows and bucks to fix the car you blew up".
