cooling idea modification!
hey guys i dont know if this has been talked about before but i think i have a good idea that could help out our cooling system, please coment and add ur thoughts!
so i was looking in a magazine and saw one of these croyo co2 adds ( you may not know what im talkin about but they make those intercooler coolers that spray co2 on the ic to cool them down) well any ways they make this kit that u connect to you intake and when ever u want some cooler air you just hit a button an it pushes co2 through a tube that is in the intake and supposedly cools the air down.
now i was thinkin that what if u placed that kit in a coolant hose and when ever your temps start to raise u can just press a button and a few seconds later ur temps start to go down... if this would work i think that it would be a pretty damn good investmen especialy with summer time comin up. so what do u guys think? a good idea? let me know! thanks

Preston, I'm not an expert, but the CO2 sprayer for IC's works b/c the cooler the air temp, the greater the combustion (decreased temp = increased density/volume of O2). For an intake, there are already water injection kits for intakes, which are prob better than spraying CO2 since the water has the added benefit of helping remove the carbon buildup in the motor. I don't believe CO2 would do that. As for coolant temps, the stock cooling system in the FD is fine. A better radiator will help, as will oil coolers believe it or not. Injecting CO2 comes across to me as trying to band-aid an underlying problem. If your t-stat is the right temp, and you have a working radiator, undertray, and oil cooler, you should be fine. No reason to go any further. Keep in mind that cooler isn't always better. There is an optimal temp at which the motor is made to run. Too hot OR too cold is bad.

what do u mean by saying it would have pressure? what the kit is, is a metal pipe with a metal tube going through the pipe. if u cut a section of the hose out and replaced it with this kit dont you think that it could lower the temps?

well i was just thinking cause i was stuck in traffic the other day and my temps went up to 220 and i do have a koyo rad. and later on i plan on buying a fmic which could be bad if i got stuck in traffic ya know

oh ok. what my original plan to do is take that pipe in the oic that i posted and put in in a coolant hose. its not some thing i really plan on pursuing, if i had the extra $ i would do it but im savin as much as posibble rite now.

spraying the co2 into your intake would actually slow your car down. thats why they make "cheetah" spray. its a purge on the side of your bumper and it shoots about 20-25 ft to the left or right. so when your adversaries intake sucks it in, it slows him down because c02 displaces o2

ya i know but im not sprayin it into the intake im talkin about the cooling system. i dont think u understand how it works that metal pipe has another pipe inside of it which the co2 passes through so in turn all it does is cool down the inner pie and what ever comes in contact w/ the pipe becomes cooler.

Spraying an intercooler will lower intake temps, not coolant temps.
The 'intercooler' of the cooling system is the radiator. If you really want to bring coolant temps down, that is the place to do it.
But I really don't see why it's so important - a quick chill of the system won't make a meaningful difference in a car that's already running too hot - if anything it would promote the kind of damage you don't want (warped housing, for example). A bigger radiator and better airflow is the way to bring down cooling system temps.

I was reading an article, I wish I could find it again, that some of the track and endurance racers actually pulled all the coolant and replaced it with a light weight oil say a 5w30, 10w30. I believe that the oil in our cars provide more cooling then the coolant anyway, but who is ballsy enough to try it???!!!
Opinions???

A few notes about that, however:
1) That rule doesn't hold true to FDs. If the stock temp gauge moves, you can turn the heat on all you want...it's too late, you're motor's toast
2) Make sure that when you turn the heater on, you position the vents to floor vents and defrost vents. Those are the ONLY positions that generate heat. All the dash vents are for A/C function ONLY.

ramy- that was a good post but i didnt know that optimal running tempse were 180-220 since my guage only goes to 240 it looked to me that when my car hit 220 in traffic, i thought i was over heating. with that being said my koyo works great cause im usualy around 160-180. oh well too bad this wouldnt really help

RX007, if you're concerned about improving your cooling system, I suggest that you do a little more research as to how the system works in the first place.
First, the engine:
http://auto.howstuffworks.com/engine.htm
Next, the rotary engine:
http://auto.howstuffworks.com/rotary-engine.htm
Finally, the cooling system:
http://auto.howstuffworks.com/cooling-system.htm
Let me emphasize a few things:
Heat flows like this:
1.)combustion chamber >> 2.)metal engine parts >> 3.)coolant >> 4.)radiator >> 5.)air
If any of these steps are not efficient enough, then bad things can happen. When people use the word "overheat" , they are usually referring to the metal engine parts becoming too hot, and warping (part 2.).
When your car was sitting in traffic, and your temps reached 220, did they ever go any higher? Did they hit 225, or 230? Or did they drop back down? Did you hear the radiator fans turn on?
Think about this for a while, and I'll post more info later.

In the event of an accident with a fire, if the temperature becomes high enough to split the N2O, it would add more oxygen and thus accelerate the fire. That's why N2O is often regarded as an accelerant at higher temps.
Secondly, nitrous tanks are commonly kept at around 900-950 PSI (requiring a temperature of 88-100 degrees F or so, so they're pretty warm to begin with) for races, and sometimes up to 1000 PSI. A 33.5 pound tank rupturing can create enough force to cause heavy damage to a car and anything near it. And even if the nitrous doesn't catch fire and explode, the concussion from the tank rupturing would be enourmous. Just take a look at this guy's car after he forgot his nitrous tank heaters on, and the tank exploded...
