DEI Cryogenic System

[AnthonyO3]

I was wondering if anybody has tried the DEI CO2 intake system? Is it anything compared to nitrous, power wise?
I am considering on getting the intake and fuel rail system for my MP3, just because i would feel alot safer with that system than nitrous.
If you have tried it on a N/A car, let us know the results, were you pleased with system or not?

also CO2 isn't as cold as N2O ( I believe). My father is a chemist. I'll check with him, but I believe N2O is -120* while CO2 is 0*.....CO2 is still cold, but not easy to refill nor as effective.

just my $0.02

Yes N20 is a lot colder then CO2...not sure of the exact numbers but Matty's seem right. But N20 is more expensive to fill.

[jersey_emt]

Plus if the system ever decided to leak...would you rather have CO2 getting ingested and causing the engine to choke and stall...or have N20 ingested without any control over flow, and no extra fuel?

Someone clarify something for me. If you were to use the CryO2 intake system wouldn’t the hot air hitting the cold bulb cause a lot of moisture to go into the engine??? If so that doesn’t sound good to me (uhm)

Like water injection, where a mist of water is injected into the combustion chamber so when it heats up it creates steam which gives you more power.
Not sure exactly how it works but i've heard it was popular back in the carburator days.

Well I know everyone wants to see what kind of gains a CryO2 kit can make. I have an old dry nos kit couldn't I just buy the intake adapter and use the N2O bottle, solenoids, and etc. to make my own kit to see if the concept works and works well???

This system is completly passive(with the exception of the intercooler sprayer.) CO2 is never introduced to the combustion chamber. Seems like lots of people are making the comparision to direct nitrous.

I would think that the intake would work with an old nitrous delivery kit though.

Matty you keep saying that C02 is hard to get. I can think of 5 places within a ten mile radius of my house. Paintball stores, Paintball fields, Airgun stores, Welding supply houses, places that sell forklifts (weird I know but there is one by my house), Propane stores(sometimes)

[Turbo Matty P]

There's only 1 place to get it within a 50 mile radius of my home....it's a welding supply store and they want nothing to do with N20 bottles.

My 10lb N20 bottle costs me between $28-$35 to fill up....only using it on the track on weekends yields me 3-4 weeks of use. Not bad for one fill up.

i also dont think theres a law againist c20 being in the car.

[funnylittlman]

Why don't you just hook up pure oxygen to the line??? :D

[Turbo Matty P]

you mean CO2?? There are no laws against N20 in a car that I've ever heard. My bottle has a D.O.T. sticker on it meaning it's safe for use in passenger vehicles. Is this something that is on a state-to-state basis??

[zmepro]

n20 isn't legal for street use (at least in california)

[bigwoofer]

You won't be able to use the nitrous bottles for a CO2 system. The CO2 system uses liquid co2 versus nitrous which is a gas form. Therefore the CO2 bottles have a feeder tube in them to suck the liquid co2 from the bottom of the bottle.
