Intercooler Liquid Nitrogen Injection Kit

[cm712]

Hay guys got a question for u could u safley use liquid nitrogen in an intercooler or any where else to get air intake temperature down ?

or would it crack your cooler beacuse it is too cold or cause problems further on in ur engine eg ur throttle getting frozen open due 2 ice froming on it ?

because it is liquid nitrogen and nitrogen is not combustible would it rob you of more power then it would possibly make ?

and could u easly inject it into ur intercooler ?

could u put it in a water injection kit and would it work ?

also how cold could it make ur intake temperature ?

Thanks guys for your help !

I dont think injecting liquid nitrogen would be all that good....for your motor...being that its a liquid it would probably lock the motor solid once it entered the chambers, it would be like filling your intercooler with water.

you would need a very special container to hold the shit and that is where the problems would start and end i think there are too many variables with the stuff to warrant use in cars + i think it has a reverse effect it eats oxygen or displaces it so not good for an intake charge and it evaporates easily. no easy way of using it i think the fittings you would need to use it would be expensive to use and maintain and safety would be number one.

oh and i think it starts boiling at like -150 degrees so yeah your intake charge would be too cold

Hay zebra man umm liquid nitrogen i think is nitrogen gas that is at its freezing point and is in a liquid state but when it is heated up it turns into a gas and when it is sprayed into the intercooler i assume it would turn 2 gas even quicker ... and Air is 78.09% made up of nitrogen.. people with Methanol/Water Injection kits do there intercoolers fill up with water or is it just sprayed on the outside of the intercooler ? sorry zebra not having a go at u or anything

[zebra]

its oxygen that burns tho....not nitrogen.

the WMI is sprayed into the intake as a fine mist.

by your first post is sounded like you wanted to fill the intercooler with the stuff

[cm712]

if you where 2 spray it in as a fine mist do think if would work zebra?

[zebra]

best off just sticking with the water meth injection.

or look at a co2 spray for the intercooler

How are you going to spray it as a fine mist? The nozzle on whatever jet you are using would freeze over in no time.

That's like using a blast furnace to cook your pizza = why would you?

You liquid nitrogen idea has kind of been done already in a much more econmical fashion. CO2 intercooler sprayers do the same thing, except they can be filled up anywhere that services soda pop dispensing machines.

Water/meth injection is completly different.

Could be in a hurry lol.

Good point 3lit 32 but it is a gas in a liquid state so it can only be gas or liquid i think so it should not freeze when i heats up but if the air in the intercooler has high humidity it may form water vapor in and around the intercooler which may block the nozzle.

[cm712]

So would it work if i put liquid nitrogen in a empty water methanol injection kit ?

You are also forgetting that you will need to store the liquid nitrogen. If you can't keep it constantly cold then it will turn back into a gas. And the window is a very fine one. At -196c it is a liquid but if it goes to -210c it becomes a solid. At -195c it's a gas again so I'd say you would start the engine, run it for a few seconds and you'd have a big container full of nitrogen gas.

Well you could stop it from evaporating if your empty water methanol injection kit was really really well insulated, but it'd likely evaporate as soon as you injected it and that'd decrease the fraction of oxygen you have to burn.

The only way you'd use liquid nitrogen is in a heat exchanger with charge air. Forget injecting it into the engine.

Your main issue would be maintaining it at storage temp over time.

[TiTAN]

no, you also have massive safety issues to deal with, a WMI tank is in no way suited to storing liquid nitrogen.

[The Dan]

No it would freeze the container and the container would break.

Unless you want to make up a special container, with a special freezer, and a special injection kit that could somehow withstand the -196c temps....then your car would be very.....special

then assuming the container is unable to vent the gas fast enough to keep the pressure down it would probably explode.

Good thought but ..... effort > gains

If you were really keen just setup a co2 spray onto the cooler.

I setup a dodgy cage one time on my FMIC and filled it will dry ice for the drags, didnt notice a difference and my intercooler was an iceblock.

Efficient intercoolers shouldnt have that much heatsoak (unless its topmount), the only time you would really notice a difference is on a 40 degree day.

true on the intercooler for heatsoak and efficiency but I have read articles on dry ice intercoolers and they are seeing inlet temps of around -40c when set up properly.

It only last for the first pass and maybe half of the second.
