DEI's CryO2 - Cryogenic Intake System
 

Has anyone seen or tried this new system from DEI? CryO2

Would this work?? What are your thoughts?? They won SEMA's 2002 award for best new product, but I can't find anywhere what the gains would be. Would they be close to NO2?? About the same price, tell me, what do you think!!

I wrote the company an email asking what the deal was and more info about it, including DYNOS.

it cools down your intake air temp, turbo guys have been using modified nitrous and CO2 systems that do the same thing for years. i think i remember seeing in my JEG's catalog a nitrous version of this system.

it works like NX's N-tercooler system, u mount the rail onto ur intercooler, and nitrous is sprayed onto the cooler from the outside, "freezing" it thus cooling the air passing thru it.....but this system uses cryogenic stuff (excuse my lack of chemistry knowledge, i forgot what gas they use)....the same substance u can find in paintball guns.....its cheaper than nitrous, and it works the same way

n2o has been used alot but is expensive as hell. Then again finding a tuner shop that can charge a bottle of CO2 might be hard to find

Co2 would be cheaper to refill though, about $4 a bottle.

Here is the thing is a nos spay going to be better at cooling an engine then a Co2 spay? I have been debating this for a few days now. Does anyone know?

has anyone ever thought about it being so cold itll create water in the IC?

it depends on the enthalpy (heat exchange) difference between nitrogen and carbon. I sold my chem. book so i can't answer but i would guess they are relatively similar.

this is a very real prospect depending on the relative humidity of the charge going into the IC. However, if the amoutn of water is very minute, then it should be expelled in a normal combustion cycle.

Water injection is also used in some F/I applications. So I don't think it would cause a problem. I have also heard of a lot of people using propane injection to up the octane and I guess help cool the intake charge.

I certainly hope it doesn't freeze the intake air :p

the colder the better ;) well to a point, then u'll just have to turn down the boost

i was told u can easily get refill of CO2 at a paintball gun shop/shooting place

its not possible. Liquid nitrogen is stored around -270 degrees (pretty sure) so n2o and CO2 would prolly follow suit. Considering the amount of air traveling through the IC and at such speed and also the small area that the gases spray agaisnt the IC i don't see how it could ever happen. However with a small IC like the MSP its more likely but still very improbable

ahhhhh i see paintball shops. good call

I know. It's just that on their website it says it freezes the air. Hehehe
:p (yes I know they mean it cools the air ;))

I haven't heard back from DEI yet, maybe if someone else writes them, we might get an answer. You can get their email address from their website.
