We are actually looking at testing a co2 mist system on the CAC on the next race truck. I know someone who has tested the water mist with very good results.

 

when dry ice evaporates solid to vapor it makes pure co2..................its very cold and the best known thing I can think of for the shell side of an exchanger...........................yer onto something real good here ......btu value is excellent


air to air exchangers can only reach 85% effency and at that point if you trippled the size of the air to air exchanger you would still only have 85% effeciency

 

The only reason we want to try the CO2 is for the velocity through the cooler fins. Might be better for us to try the dry ice first but I'm not sure how we could get enough velocity through the fins and cover enough surface area with it.

Since we hi jacked the thread and moved on to another topic everyone keep on the lookout for a wrecked single cab DMax. I still cant find one.

 

go with a cylender of CO2..........get it from yer beer or pop dude...get a regulator then build a displacment nozzle to yer fins then a solinoid switch activated from the cab or by master/slave on boost pressure when it reaches say 20 lbs........let er rip dude

 

Thats exactly what a particular individual did with the water mist. Sorry guys, I cant reveal who it is yet. He built a nozzle system across the CAC and then used a CO2 bottle to power it. We couldnt believe the temp drop we saw.

 

I don't know if it would stay concentrated enough but co2 will kill an engine in high enough concentration. The only thing dry ice or a "cooler" would be good at would be a drag race or sled pull. I know somebody who used an air to water intercooler and he could melt the ice like nobodies business. now if you could use rock salt in it like you do with ice cream you could get it real close to zero...but salt and aluminum intercoolers is a real

 

I deal with this CO2 daily and can tell you its the answer big time........bigtime


I bet you could keep inlet temps to 120*

 

Thats exactly what we're talking about. The CO2 is powering and chilling the fluid so its not actually concentrated enough to affect the intake air. The nozzle system built injects directly in front of the CAC shroud. The set up that was tested didnt open up the bottole until WOT so it only saw an 8 second burst. At 150mph there was enough oxygen saturation and flow across the front of the truck to make sure it didnt suck up into the turbo. Keep in mind that this is a race truck that was seeing 2000*F EGT's most of the run. But, YES, spraying CO2 directly into the turbo is what most tracks use to stop a run away.

 

I sure wish they could make a stainless steel Air to water heat exchanger...cuz I'd be all over that like flies on a pile of poop. ICE+WATER+ROCK SALT=REALLY COLD!!!!

 

this thread started with some asshat and a stupid no workie ider he had..............I was joking bout using co2 injected into the motor........its and inert gas and cannot support combustion

I was however serious about using it externally on and air to air exchanger

Phil......the make a **** ton os SS air to water tube and shell type exchangers
