CO2 injection?

[Jetty LBZ]

i know there is propane and nitrous injection and basically how they work but i found a CO2 injection kit called CryO2 and had never herd of one before. im just curious how it works. could someone explain

The one's I've seen just use it for cooling. It doesn't actually go into your motor and you wouldn't want it to also.

Sounds like internal fire suppression.

:spit: Yup.

You hook the system on to your intercooler and its sprays it to drop intake temps
On my 300zx I saw a drop from 140f down. To 75f with a small side mount intercooler I don't. Think its a big enough gain to try imop

From reading their site, it appears that it just uses the expansion of the liquid CO2 to cool your fuel and/or air before going into the engine. Like everyone says, the CO2 itself doesn't go into your motor.

Using the spray system leaves the chance of the intake sucking in the CO2. Some of the other kits use a sealed system that works like a heat exchanger.

I made a large spray bar for the front of the IC. Durring a pass if it was used, it slowed me down. im guessing the intake was seeing some of the Co2. I also used it in staging when i was the 2nd vehicle back to soak the IC. Actually killed the truck one time:rofl:, but i did see 1mph gain. Not worth it IMO, i was going through a 10lb N20 bottle every time i soaked it lol. The staging guy thought i lost the radiator the first time i used it in staging, and wanted me to shut down

Cry02 works in theory. Im gonna try it, and i think matt is too

I actually have heard of guys back in the street racing days using co2 like NNNOOOOSSSS foggers and spraying them towards the other guys ricer to slow them up :rofl:
I have used water meth on intercoolers to help cool them... wrx sti's come with it from the factory

Where do the kits dump the exhausted Co2? As long as it's kept far away from contaminating the intake charge, it might work.

I've seen some into exhaust or into another exchanger or "cheater jets that would blow towards the other guys car/truck like MuscleTruck03 said.

My intake on myz came thru the head light.

 

[Jetty LBZ]

thanks for the info everyone. im not interested in doing it just wanted to know how it worked

 

[juddski88]

Cry02 is a self contained system as far as i can tell, no co2 exhaust into the engine bay.

IMHO I wouldn't drop the coin onthe cry kit. I'd just pick up the parts to build it myself.

My system(not done yet, due to those damn cup issues,now solved...thank you DTS) consists of these tear drop shaped aluminum bulbs, that are mounted, and plumbed into your charge air piping. Triggered by full throttle switch, button, hobbs, etc. It can then be exhausted wherever you choose.....intercooler, oil cooler, trans cooler, etc. Just keep it from entering the intake airflow. Should have it mounted and plumbed next week. I'll be sure to get you guys some before and after temps.

I've got some CO2 stuff in the works. A little different than the stuff on the market now. Should use quite a bit less CO2 per pass and still get the job done. I'm planning on working out a test stand to see if the theory transfers. If it does, I'll do some dyno time this winter and hopefully have something ready for spring.
