liquid nitrogen to air intercoolers...

[no_8wire]

I know this may sound wierd...but with enough money could it be made to work? Similar to water to air...expect liquid nitrogen instead... only thing I can think of that would maybe stuff it up is
1: cost
2: extreme cold crack the intercooler steel/ makes it useless...
3: interesting valve system to be able to fill/top up...
4: cost

cold air doesnt atomise petrol as well.

So you get diminishing gains, not much point going much lower than ambient air temps IIRC.

And bearing in mind that if you dip a banana in Liquid nitrogen you can hammer in nails with it, I dont think that ANY piping is going to take too well to being that cold and having super hot gas running through it.

When heated, you'd probably get an explosive result when the liquid nitrogen turns back into a gas rather quickly.

[AE91Sprinter]

Well, theres an easy way to try it. Make a box, pack the IC in ice and dyno run it. Or just do it for the hell of it and see what happens by feel if you dont have a dyno handy

[no_8wire]

explosive is not good...

[bluemaumau]

very interesting idea. doubt it would be worth it tho for all the reasons mentioned.

[no_8wire]

yeah was just an idea...not a whole lot of room in an aw11 engine bay...want the most effiecent cooling possible...

oh well might just stick to water to air...

[RomanV]

Well it's not as if it would be a viable solution anyway...

Unless you like buying and handling liquid nitrogen all of the time.

[Stealer Of Souls]

Single shot wonder cooler?

Yeah. Re-liquifying the nitrogen could be a challenge?

Even sub-zero air can be use effectively if the engine is tuned to handle it. I've seen supposed results from a dry ice IC that had intake temps below zero. The before a suitable ECU tune had the engine lose power like crazy. But after a suitable ECU tune the engine cranked out some serious power. I don't know what fuel they had to use though... Maybe they went for something exotic...

[Grrrrrrr!]

It could be made to work.. might be a bit of a challenge tho.

Maybe a multi stage system to reduce the temperature difference between layers
Something like
Liquid N2 -> Alcohol(or other low freezing temp fluid) ->Water -> Air
a shot of Li N2 into a vented chamber in a brass or copper heatsink imersed in Alcohol, which is circulated thru a water to air intercooler as per normal. And when you run out of LiN2 at least you still would have a normal water to air type intercooler setup

Your litre or so of Liquid N2 would go a long way, but youd have to shoot it into the system a few seconds before you needed it to allow time for the thermal lag.
Also if the alcohol spilt onto a hot turbo manifold you could have a very nasty situation.. good old invisible flames with burning alcohol.

And the second you have a head on crash, your burning in 10000 pieces with whatever you hit.

Thats the main problem IMO.

what about the CO2 IC systems?

would have to worry about exploding during impact if its securely in the boot. and would possibly aid in dampening the fire if one was to start

[SpeedRacer]

ive seen one with a box round the i/c and dry ice packed round it in a magazine once, duno if it helped or not but must of done something (bling maybe?)

[KinLoud]

Use liquid oxygen... straight into the intake - no intercooler required.
You might however need a dangerous goods sticker "oxidiser" on you bumper.

hmmm, and if add more than about 2% oxygen you'll be needing to up your fuelling very quickly.. oh and your exhaust valves will probably turn into nicely melted blobs in very quick order

wasnt a yellow GTi-R poohsar was it?

that is in this months Rev i think. was next to TS at the stand at the 06 Nats. the guy was always topping it up. looked pretty good and functional.

I've wondered about this. Like NOS?

nah it was a white 5zigen WRX i think, was like 2 years ago in a nzpc mag

Um, you do realise that nitrogen isn't combustible and does not support combustion, right?!

I could be wrong, but think he means more like this...

the aussie distributers are these guys.

the website is just some random free email thing though, so I'm not so keen to do business with them.

There was a guy with a WRX that was using a set of them to cool the air charge on PCTV either early on this season or late last year.

It's an interesting idea, basically this bulb thing sits in the middle of your piping, and cools the air that surrounds it.

they should give better info on how it works.
