I'm making a nitrogen intercooler manifold to supercool the intercooler for short burst cooling. Think it will work? :crazy:

Liquid nitrogen? ;)

That's right Jim, liquid Nitrogen. Non explosive, non flammable and cheap. Should give me a very low manifold inlet temp as well as a very cool Disco fog show when used :lol: :crazy:

It looks a lot like the spray system I've seen on airconditioning condensors when used in desert conditions. They spray a fine mist which is mixture of water and alcohol on the condensors, when pressures start to rise. Using nitrogen it should provide a very effecient method of instantly dropping the temp of your compressed air. The water/alcohol doubles the cooling capacity of limosine A/C systems.

Are you crazy? Were will you store the tank and how will you keep the nitrogen a liquid its like-180*F. :crazy:

Stingraycrazy

Yes I'm Crazy! :thumbs:

I use nitrogen with my work for device calibrations. You know, you can freeze and orange solid in less than 15 seconds. A small 5 lb bottle tucked under the rear of the car activated with a solenoid valve and plumbed to the intercooler with 1/4" SS braided line is the plan. :crazy:

How are you going to keep the bottle cool? :confused:

O ris it that when you have liquid nitrogen in a tank it cannot become a gas or lose the coldness and become a gas because it is pushed into a small tank when at a liquid state. So the Nitrogen cannot become a gas so it is forced to stay cool and be a liquid, is that how it works? :confused:

Stingraycrazy

You dont need to... Nitrogen will stay in liquid form under pressure. You just need to mount the bottle tilted upside down. The nitrogen will flash to a gas at the intercooler and will hopefully super cool it...

WO!! :eek: :cool:

Why not use CO2? Commonly available (beer taps!) safer to use, easier to store.

Any adiabatic expansion (like the rapid expansion of a gas from a compressed state) will cool your intercooler.

Have you ever seen what happens when you let -196DegC (-350F) liq N2 free? The whole stuff ices up, I've used enough of that stuff to know oit's dangerous. IF you get a leak and it gets in the interior you will suffocate. If there's a leak and you get some boiling N2 on you you will either get serious frost burns or loose fingers (I saw a dude spill some from a Dewar container on his fingers, one fell of and broke in pieces like the terminator in TII Judgement day)

you guys are nuts :lol: but you are also very creative :cheers:

I work with liquid nitrogen daily. It's temperature is minus 190C or around minus 327 F. It is never stored in a sealed container, never. The containers are glass lined thermos. It is only about $1.50 per letre Cdn. Cheap but dangerous to handle. I demonstrat it is lab classes all the time and even put my hand into it quickly. Certainly freeze things. I can not see you putting it in a sealed container or sending it through a valve. It would freeze the valve, freeze the line and cause both to fail. Metal becomes extremely brittle at this temperature. Correctiong ferous metal. Aluminum is not affected. It is a face centered cubic not body centered.
Nice job on the intercooler but I am very sceptical about your handling liquid nitrogen. While I don't consider it dangerous and let my students play with it controlling it the way you want is tricky. The only real danger you are getting yourself into is trying to contain it in a pressure vessel. I have never looked up the pressure it will build to so I can't be sure.
Good luck and don't blow yourself up.

after reading up on liquid nitrogen i wouldnt want that stuff in my car :crazy:

You are crazy. i can only hope to be a nutz as you one day :lol: i would use Co2 also. you can buy the paint-ball gun ones at wall mart, and they are already designed to be in a pressure type system. pull the trigger, open the valve, shoot your buddy in the *****. it wouldnt be that hard to develop a "NOS like" system for quick bursts of co2 to the intercooler. or long ones for racing. you could use the NOS system that uses a throttle position sensor.

Titanium rat. Liquid nitrogen is fun stuff to play with. I dump it on my clothes, stick fingers in it, freeze stuff and don't consider it dangerous. Sure you could freeze yourself but it hurts so you either pull your finger out or dump the stuff. It doesn't make cloths wet, they steam or smoke but don't get wet. The only danger I can see is if confined in a sealed container it will build pressure. I don't know how much but I could look it up once back to work. It will blow up , but only do to pressure building in a seal container. This will kill you. If the valve freezes open it won't hurt anything. If a line breakes it won't hurt anything. It does not burn. It is harmless but it can of course cause burns but it is always stored in open glass lined thermoses.
Sure gets rid of little moles on your skin.

I don't really see the point in doing it that way. Most of the turbo guys in NMCA/NSCA/NMRA use ice with the water/air intercoolers. They are able to get IAT's in the 30's/40's F. You might pick up a few hp by dropping the IAT's even further, but you're already going to have much more power than your chassis can handle as it is. I just don't think the added effort, weight, complexity, etc provides any worthwhile benefit over a conventional intercooler. You've got plenty of intercooler capacity already, more than you really need based on your hp goals.

Another thing to consider is the negative metallurgical effect of the liquid nitrogen on your aluminum intercooler. I can't help but think it will lead to cracking.

Worst that could happen is that the extreme temp change might crack the brazing of the intercooler.

A lot of guys spray their intercoolers with C02 (from a fire extinguisher) before they go down the strip. If you think you can get it to work, more power to ya.
