gut your ic fins and tubes,weld ally sheet around the end tanks to make a hollow box and fit refridgerated lines in the said box and bob's your uncle....crisp cool intake air to provide that dense charge to the chamber.

Could be onto something there Krankin.

just making use of whats allready in the engine bay and some small additions.
How would you power refrigerated lines? An extra compressor off the crank? Which could kind of work, actually. But would the power draw off the crank be worth the extra power from a cooler intake?

? The idea of mentioning changes in volume is to utilize that for air intake. But really won't a big deal for intake anyway.

I have thought about this bit in the past. With maybe a water to air Ic with an ice box type arrangement but with refrigerated water. The problem is that there isn't much evidence of anyone doing this so there might not be a gain once you add the loadfrom the compressor

In the early F1 turbo days they used crushed dry ice infront of the the intercoolers.
Dry ice has a surface termperature of of -68deg C
I have seen gadgets, mini heat exhangers for fuel that went into the suction line of the AC. Great for petrol but probably not so good diesel.
Just waxing ideas

Yeah I thought about this as well and decided that the drain on running the ac would not be worth the gain on the ammount of boost I am running.
I think the idea has merrit but the current intercoolers would prover more effective in the long run.

In terms of advantage vs cost vs energy ("bang for buck") you'll probably find a water misting system to be far superior (remember the COST part of this). It should set you back about $20 and just fill it with water when you remember. If you don't fill it - no drama, it's back to the current way without any disastrous side-effects.
You CAN add alcohol to that. Alcohol is more volatile which not only means it's more flammable but it evaporates several orders of magnitude faster than water. Don't forget that the misting system is only effective because of the evaporation part of the process, not because it's wet, so alcohol is going to be much more effective than water. Even unleaded fuel will work better. The problem with alcohol is threefold: first it's more expensive, second it's highly flammable and third it's too tempting to use it in other ways.

Only any good for those who use the aircon though. I rarely use it as it just isn't hot enough to need it

I put mine on ever couple of weeks.
Keeps the oil moving and lubricates the seals.
Dunno if I am imagining it, but the ute seems to go pretty well with the air con on.
Like its a different map or something.

Northside loves using his Dyno.
He probably has dyno figures somewhere.

would you do the mod though???
those that would, will run the ac, doesnt mean you have to have the cabin frozen,
and you wouldnt need it when the ambient outside/intake air temp is low anyway.
The one's that are pedantic enough to do such mods, do what it takes.
Very, very costly.
Using power off the crank for an air con system for IC seems a bit drastic. Wouldn't it just be easier to use an electronic refrigeration? Like, just dismantle a mini fridge and use that.

Your right in a way however with the refridgeration, the power for it has come from somewhere.
The problem you can't get around it's Entropy- the second law of thermodynamics.
Put simply there is no such thing as a free lunch.

whatever floats ya boat mate...just puttin it out there...
for me personally it would be a very cheap option as my bro inlaw runs a large transport ac/refridgeration Co,
and also we have a fridgy at my work in our dept so basically the job would only cost me my own labour time
and even so without the above, it wouldnt be hugely costly imho,
and,
for those in pursuit of that extra bit...whats costly???

just like those who scrooge about putting the ac on driving down the hwy, but open all the windows...go figure
According to my ECU, the air conditioning compressor adds about 8% load to the engine. At idle, typical load is about 21% and with the air conditioning on the load rises to 29%. I don't know what that would equate to in terms of horsepower.
