Cryogenic cooling kits...
Turbo Mini Forums

i have been looking at a few site which do intercooler co2 spray kits. i was wondering has anyone used these before or ever really heard about them being used?

i thought they were quite good and thought even of spray for the rad to cool down water temps if the car is getting to hott? anyone thought about this before?

seems pretty good. only thing is how hard/expensive is it to get the bottle refilled? obviously this is alot better than just using a fine mist of water but if its rediculously expensive to get it refilled (i know you are only going to be using a very fine mist at a time but you are going to have to refill it at some point) is it really worth it over say a water mist system with either a seperate rad so as that cools the water in the system or a tank that you could put aload of ice in with the water to help lower the temp of the water that is being misted?

just a thought. i would like one as i am looking at going to intercooler and mist system route but i would need to find out how much the refilling would be and then weigh up the cost.

its cheeper than nitrous i know that much, and lighter than a big tank of water. i thought the kits were of quite a reasonable price.

sounds good too me then i thought the price of the kit was pretty good too i just didnt know about how expensive and easy it was to get the bottles refilled.

i might well be investing closer to the time

im not sure if you are aware but that is excluding the bottle :) it would be able 300ish i geuss for the kit and a bottel

:o ohhh i wasnt aware, i didnt fully read it and missed that bit! maybe i will be setting up my own system after all

old fire extinguishers is all i'll say

i'll never get round to doing it on my car but it has to be the way to go.

The fire extinguisher IS the CO2.

ahhhhhhhhh i seeee

Or a welding bottle from Machine Mart.

Probably going the water spray route myself as it's cheap / virtually free.

That said I've not really heard of using CO2 for cooling, where's Sprocket gone.

Its meerly a trick that drag racers have used on turbo cars for years and years. Spray the intercooler just before a run with CO2 fire extinguisher (powder is a no no) and get into the -*c's

However they can also use dry ice which can get even colder bout -78.

I belive co2 kits when activated to spray intercoolers turn them into a block of ice or "dry ice" making the charge air cold. Ice that comes from co2 from the expanding gasses form the dry ice. I was speakin to someone at work who looks after our fire extinguishers he reckons £15-£20 for refills. Another thing to be carefull of i suppose is where the air intake is situated, you wouldnt want it sucking in co2, not got good for power!

Water spray is almost free, and easily replenished, and if done correctly, Id say works pretty damn good...

Go check Autospeeds automatic IC water spray kits.

speed didn't kill me, but taxation probably will

You have to ascertain that the weight of the system is worth the sometimes negligible power gain though .
Might be a good idea in real hot countries though.

dont some evo's and impreza's use water sprays on there intercoolers, think the evo cuts in automaticaly and the impreza's in manual

I've done a bit of searching on line and I've found a circuit for controlling a water spray based on air temp & engine load with both turn on & turn off hysteresis. I've done some quick & dirty maths and I reckon that if I was to build a batch they'd come to about £20. so the question is would anyone be interested? If so I'll look into it a bit more when I'm back in the UK (just over a week's time) I might make one for myself anyway.

well you'll never find one of them on my car. I did some test on the rolling road, and my advice is not to fit one.

Worsemate, in my tests the car lost a small amount of power, this is unlike me to share some thing like that lol!

the best is to use Hp comp air from say a diving light weight cylinder be a damn site cheepr to refill , and better carbon footprint.

always looking for them bigger bunches of bannanas

Matt if it's "Everyday Practical Electronics" (Jan 08) I've found a copy on line, if it's a different article could you get me a copy as it's always good to compare designs. Can't do much with it for a week or so mind as I'm off to France in a few hours.
