DEI CryO2 system?
 

does this ---- work?
http://www.cryo2.com/products.asp?m=sp&pid=3

i was under the impression that you wanted your fuel to be really hot in order to get better atomization. if this does work i was thinking of making one but with N2O running through it. i'm also going to make the intercooler sprayer. that bulb thing in your intake tube looks pretty lame though.

just looking for an opinion.

Re:DEI CryO2 system?
 

I thought the fuel was supposed to be hot too. I have heard that running rich on a turbo motor is better combat against detonation because the fuel COOLS THE INTAKE CHARGE also.
It's probably a one or the other proposition. The cooler fuel is probably better for turbo though. :-\

Re:DEI CryO2 system?
 

well i know you dont want the fuel to be too hot, but ive never heard a downside of it being cold :-\

Re:DEI CryO2 system?
 

that looks cool, i'd try it if i had the cash to spend :-\

Re:DEI CryO2 system?
 

We are a dealer for DEI Products, but have yet to have any firsthand experience with the CryO2 stuff. We have used their heat wraps and shields though.

We'll be meeting them at SEMA this year, and will be sure to talk to them about the pros and cons of using this on a turbo system.

As for cooler vs hotter. It used to be that cooler air was denser, and more molecules equaled better combustion. By cramming the air in with a turbo, the need for cooler just might not apply anymore

BTW, If you do not like the intake bulb deal, DEI does make a intercooler sprayer - http://www.designengineering.com/pro...asp?m=sp&pid=5

Also, CO2 will be a lot cheaper than NOS when it comes time to refill your bottle. If you are just using it for cooling, it might be a bit more cost efficient.

Re:DEI CryO2 system?
 

it works if you spray the intercooler i guess, my buddy had it on his n/a eclipse and it didnt do anything except caught fire...yes caught fire, the pressure in the bottle built up cuz it was warmer outside and when he sprayed it the nozzle blew out of the intak pipe and landed on the positive battery peg. try it if you would like, maybe it would work on a turbo'd car.

Re:DEI CryO2 system?
 

i didnt know co2 burned? intereesting

Re:DEI CryO2 system?
 

im going to build one and tell yall the results. it will be water cooled. it will be kind of like a tripple waterblock system. with water wuning on both sides of the block. if you know about water cooleing pc's then you could understand it allot more. and plus, you never run out of water because the system will be a closed loop.

Re:DEI CryO2 system?
 

annd then it will heatsoak

Re:DEI CryO2 system?
 

well, cold fuel causes waxing on its petroleum properties therefore will not be as efficient. I know for a fact that in my line of work, we have a fuel heater that maintains 60-90 degrees... but we use diesel.... and this is on a 100,000 bhp ship... lol.

Here's a tech on cryo2 vs N2O;

I'm a cheap mofo, so I did this instead:

... and Craig... you have a PM sir ;D

Re:DEI CryO2 system?
 

Okay, so I did some reading, thanks to Thermal!

I figure the following are true....

- Although CO2 is cheaper to refill, it causes HP loss becuase as it sprays through the intercooler increasing HP, it get's sucked into the air filter, causing lost HP, with a net loss for the whole system.

- NO2 is more expensive, also cools the IC to increase HP, with the stray gasses getting sucked into the air filter and into the engine, further increasing HP, causing a big HP net gain for the system (50 HP increase on a 250 HP engine).

Interesting....

So even if you could keep the CO2 out of the combustion track, it would never perform as well as a poorly implemented N02 setup, because the stray NO2 also boosts HP.

So I guess it comes down to figuring out if the cheaper cost of CO2 is worth loosing those additional ponies gotten from NO2.

What's the difference in cost to refill the same bottle with th edifferent gasses?

Re:DEI CryO2 system?
 

the cheapest ive found to get my tank filled was 4 bucks a pound in n20 i dont know about co2

Re:DEI CryO2 system?
 

...then just use the kit that goes in the charge pipes, it doesn't actually get in your intake stream, it just cools it down. I dont think c02 is combustable either so never put that in your air stream as it will starve your engine of oxygen. Anyone care to confirm or deny this?

Re:DEI CryO2 system?
 

co2 is alot cheaper but its nowhere as near as cold as nitrous. Nitrous burns its soo cold but as little kids you can huff co2 out of the little pellet gun cartridges.

Re:DEI CryO2 system?
 

Nitrous may be super cold but you can even freeze-burn yourself with cO2, i've done it a lot.

Re:DEI CryO2 system?
 

^^^wouldn't you leard after the first time??

That is just a bonus to running CO2, you can huff it b/n passes.

Re:DEI CryO2 system?
 

It is confirmed in the reading links Thermal put in a previous message.

And if the CO2/Sprayer Bar cause problems, the DEI intake cooling system looks perfect!

We'll get our pricing on these later today, and hook you guys up with the best deal we can.

Re:DEI CryO2 system?
 

OK, you guys have this all wrong. The CO2 never enters the fuel system or the motor in any way. It is just used to cool the fuel. The cooler you get the fuel the more dense it is and you get more of it in the motor. Its the same as using an intercooler to cool the air going into the motor to give you more air to make more HP.I do think this fuel cooler thing would work better on an all motor set up. The "bulb" thing that they make that goes in your air intake pipe will work on a turbo set up. The CO2 "super cools" its self and that cools the air going into the motor. Again, NO CO2 enters the motor. Remember,CO2 is what is in a fire extinguisher, I think that would be bad to run through your motor :(

Re:DEI CryO2 system?
 

Then the bulb also poses an imperfection in the charge pipe section because of the space it occupies.... not to mention the chances of condensation within the charged pipe or on the bulb itself... now the risk of having moisture in the charge pipe is available.... just my opinion tho...

I do have a cryo2 set-up on my Teg... but filled with nitrous instead. I got the kit for free. Plus the local law doesnt say anything about CO2 systems in the car. If I get pulled over and get inspected, the tank is marked with CO2 not N2O... I hope I dont get fucked ;D

Re:DEI CryO2 system?
 

You have laws bitching about N2O on street cars? :o

Re:DEI CryO2 system?
 

First off, I have used the CryO2 system with much success and would recommend it to anyone. Concidering that this is a home made turbo site I would expect more of you guys to figure this system out. Here are a couple of answers to some of your questions:

1. Temp of liquid Co2?: -80 degrees
2. Can Co2 catch on fire?: Hell no! Fire extingishers use Co2.
3. Will the system make power?: Yes the system will make power. It just needs to be used properly. I am running a FMIC and i normally prime the intercooler to prep it for battle. I do recommend that you plumb you intake away from the Co2 vent. My intake is not in the best place, but I use the system correctly and I have seen .5 results from a heat soaked condition at the track.
4)Go to www.designengineering.com and check out the down load section Performance Ford Magazine gained around 25HP from a heat soaked condition and 8 from the base run on a Cosworth.
5. Does cooler fuel make HP?: Yes, and if you do not know why ask your Highschool chemistry teacher.

Here is also something that I found on a Mazda Forum:
I have seen some old posts regarding DEI's CryO2 system, and if it actually adds HP, and how. I am a Mechanical Engineer that actually liked Thermodynamics. To the best of my ability I will describe mathmatically where the HP comes from (what I feel to be true, someone correct me if I am wrong).

First off, CryO2 does not directly inject anything into your engine nor should it harm your engine in any way. It simply cools the air before it enters your engine. Carbon Dioxide (in the liquid form) is injected into a metal "holder" that mounts inside of your stock intake piping. For turbo applications, after the IC and just before the intake manifold would be best (what I might do). It will cool the air at the very end of it's "travel". The same reason for intercoolers, but intercoolers will only cool the air to a certain extent...remember it heats up as it passes through the turbo. The IC just brings the air temp back down after the temp rise at the turbo, (To what degree I do not know). So here is a bit of math.

Mass of air entering engine (in pounds)= (P1*V1)/(R*T1)
where:
P1 = initial pressure of air
V1 = initial volume of air (in cubic feet)
R = gas contant = 53.3 for air
T1 = initial temperature of air

For my application (MSP)
P1 = 14.7+8.0 psi = 22.7 psi = 3269 psf <----you can see why psi = HP
V1 = 2.0L = 0.071 cubic feet
T1 = well.....this is what the CryO2 will change
Remember it will be in degrees R which is degrees F + 460.

The greater the pressure, the lower the temperature, the higher mass of air, the more power. Internal E = C*m*(T2-T1)
where C is another constant for air. T2 (after compression) will be approximately the same (I won't do the math for you because this is getting long), so T2-T1 will be larger with a smaller T1. And with a higher m (mass of air), you get an even higher value. They are all minute changes but add up trust me. I calculated 15-20 extra horses on a computer application I wrote years ago that solves for HP and lets you change any factor you want.


Try it.

Re:DEI CryO2 system?
 

the fuel coller is not a new idea. All my old school draag racers buddies used to do it with a coffecan that had a meatl line coiled inside, they would put that inline with the fuel and when it is time to run they would drop some dry ice in it
