Math behind DEI CryO2 system = + HP

Most applications of thermo, phase changes, etc involve a very important value of Cp which is the speicifc heat of the fluid/gas. This is the amount of heat per unit mass required to raise the temperature 1 degree C. Vaporization absorbs a lot of energy and can be seen using the perfect gas law (PV=nRT). You can view the Cp values for many liquids, and this is how one should compare methods of cooling intake charge. This value alone can be used to compare CO2 and others (in the liquid form). I am sure charts can be found online.

On the subject of cooling the intake charge, I haven't seen many people talk about water/alcohol injection kits on this board. The atomized mixture sprays into the charged air and vaporizes. As Mr. MechE, the thermodynamics buff, knows. . . the phase change requires a great deal of energy. Consequently, the intake charge is cooled dramatically.

Here's the system I have for another application: http://www.aquamist.co.uk/cp/sys2c/sys2c.html
Yes, however. THe Water displaces fuel and air, so...the intake is colder, but you have to add boost to compenste for the lost HP thus heating up the intake more as the turbo pushes harder...

Lotsa educational stuff here. Subscribing so that I can get educated real good!

my brother play paintball alot and he used to have CO2 in his bottle but changed for N2O because CO2 was too cold. it would freeze the connections and could en up being dangerous if used for too long (happy trigger). So he switched to nitrous because it's not as cold

why would this be different for cars ? He showed me what his CO2 bottle did before and you could see the whole gun freezing ... that doesn't happen anymore with N2O ? or are there 2 different kinds of nitrous ? one that would not be "true" nitrous
 
Sounds like the CO2 will coll better, my point is this though. If you have the N2O in the car, use it to cool the FMIC and Kick a 50 Shot. If you only want cool then CO2 is your way to go!
 
yea that would make more sense ... the system is already in your car

but you know what ... in french, people call nitrous oxide "nitro" and they also call what they put in those paintball guns nitro too. but i think the paintball stuff is just nitrogen instead of nitrous oxide. that would make more sense. cuz when we looked at my brother's gun, it was warm. there's no way we can use that stuff to cool anything in our car. so im pretty sure they're different

C'est le N2, pas the N2O.
 
The instructions are rudementary, pretty much...you have to know what you are doing to install the kit. DEI says: Connect tube to tank, run tube from tank to solenoid, connect tube to solenoid, etc etc. If you know how to use fittings, and work with braided line, I am guessing install is easy. Most work is mounting the tank, running the cable nicely, and cutting your intake pipe to accomodate their attachment. I am still talking with DEI about sponsorship, installation, etc. I have the money....but I just bought HiBoost FMIC, and I try to regulate how much $ I spend monthly otherwise I would be broke. Maybe in the spring. The $150 ticket for "squealing my tires" and illegal tint this past weekend also doesn't help.
 
Yeah, the concept of installation is easy to understand, however, with the kit being as "rough" as it is quality wise, it leaves a lot to be desired. If you do get this kit and they have not improved quality, expect quite a bit of self rigging time. This is certainly not a ready-out-of-the-box kit.

I will look into this. I think they might install it....but if the quality sucks I do not want to be fixing it at a later time.

BTW HiBoost just arrived. :) Next weekend better be nice weather....
 
The expelled C02 from the cryo i was told can be directed thru a line out the rear bumper on your ride which then gets sucked up into your competitors engines making them run rich, and have a loss of HP... Kinda Sneaky
