DEi Cryo System?
Has anyone heard of these? I recently was told about them. They are like nitrous but with O2 instead.

no a cryo system is to cool your intercooler it sprays really cold
02 on your intercooler to keep it cold .

If you've ever used one of those "canned air" cleaning sprays on your dusty computer, then you know how this setup works. The "Can" gets pretty cold as the liquid expands into a gas. The bottom line is that as a gas is compressed it heats up, it then loses its heat and when it re-expands it is now colder. This happens in your fridge, in your AC etc. etc. etc...

Rep Power: 312 if you have a tank full of pure oxygen gas in your car, and you crash and catch on fire, you are screwed. The Nitrous will not burn unless under high pressure and temp (kinda like in your engine), but the Oxygen will feed whatever fire it finds. Look at the Apollo 10 capsule (i think), it burned because the fire was fed by all that O2.
I am not saying it wont work, because it will work rather well. But i just think its a little dangerous.

Well they have a bunch of different systems. One system is a shot, one system is a air intake cooler, one is an intercooler cooler, and one is a fuel cooler. I think basically they are going on the point that the cooler the air/fuel mixture is, the more HP.

Rep Power: 0 The reason why NOS has the Nitrogen component is exactly like Catalyst described. PURE oxygen is very dangerous. Generally speaking things have a certain temperature that they combust at. The more oxygen in the environment the lower that combustion point. I don't know what temp gas would combust at in a pure oxygen environment but it might actually be less than normal room temperature!!!
This is all irrelevant however, THAT system above has very little similarity to a NOS system. They function completely different and accomplish completely diferent things.

Rep Power: 0 One other thing to point out: This system does not use O2. It uses CO2. Go grab your CO2 fire extinguisher and spray it on your hand*. See how long you can hold it under the spray. After this little experiment you'll know exactly what is going on here.

Rep Power: 412 I thought it was CO2 but it never really states clearly. We use CO2 to euthanize the animals in our lab and I know it get cold. I just wanted to some feedback on what people thought of the product. I would never get it for my car.

Common sense suggests that the three components here would probably only really help if your car is under boost. By lowering the intake charge temp and fuel temp you increase fuel and air density (more power) at the same time reducing the temperature let's you run higher boost by lowering chances of detonation.

Rep Power: 312 actually, with our cars, you want the fuel to be warm, because it vaporizes better. We tested it on my crx, and hot fuel made more power. I know that cold fuel has more punch, just like cold air, but the fuel is easier to vaporize when it is warm.

i shoulda paid more attention in science class.... but my point still stands
