I would be just talking out my ***, I'm just thinking. If I replace the water with a difference liquid/refrigerent. Would It cool better? Anyone done this?

you know, my old nitrous bottle was pretty much cold all the time. ... wonder if that could he flowed through the liquid intercooler and keep it down, maybe have some type of relief valve to when the pressure got real hot it wouldnt expload....

Wonder if liquid co2, would work and its cheap as crap.

Just thinking out load, all ideas would be good.

 

The only way that you could cool the air/water better would be to A) evaporate a liquid inside or on the core, like CO2, liquid nitrogen, liquid oxygen, liquid helium ... or B) use an AC compressor to basically make an airconditioner inside your tank by chilling a coolant and pumping that into your intercooler or you could get a custom intercooler made that will let the refrigerant evaporate directly onto the intercooler core.

 

or just use ice/water like everyone else.

 

Crushed dry ice is my bitch.

 

well it was an idea :-). I figure something didnt work since I hadnt heard of it before.

 

Some guys drop a pint of cheap alcohol in with the ice and water. We tried it but can't really say if it helped or not. At least it didn't catch on fire and blow up

 

alcohol(methanol or ethanol) has a higher thermal resistence and worse(larger) boundry layer then water. The only thing that alcohol will do for you is lower the freezing point of the water/alcohol, which is a good thing if you are going to chill the water with dry ice or a freon/refrigerant (R-22 perferably over R-12 or R-134a) setup, but is pointless if you are just using ambient temperature water for the heat transfer.

if thats correct information, its good to know!

refrigerent need to be compressed to be efficient in cooling, b/c they are a gas a room temp. compressing them will make them a liquid at room temp. this is how your AC system works...simply adding refigerant will do nothing. it requires a compressor and pump to circulate the exchange btw gas and liquid forms of the refrigerant.

 

using a compressor and stuff sounds like to much work for the gains, do you agree?

I have a friend that uses an AC system to cool his water tank.He uses an Accel DFI system and the AC only runs at low throtle position.Oh,and its a Pantera with about 400 ft#s at 2000 rpm.

 

http://designengineering.com/ is company that makes a CO2 charge cooling kit...

 

Here in Canada we believe in the maquiver method

But on a serious note most people around here generally add some alcahol to the mix.

thats a good way to cool the charge

try alcohol and dry ice. The temp of those 2 combined is -30. I think you wont find anything much cooler than that.

 

A good friend with a built Cyclone would always drop a big *** chunk of dry ice in the aftercoolers resevoir*. It worked really well to cool the intake charge, that was until the truck lit on fire one day and has since been cut up and parted out.

 

an idea i had was to use a thin copper tube routed from a CO2 bottle (or other compressed gas). use a temp sensor to trigger the bottle to open at a specific water temp. the CO2 would go through the tubes (tubes wound into a nice coil- maybe even part of a heat exchanger core) chilling it down as the gas vented to atmosphere. the cold core would be in the water tank with the pump outlet directing the water over it, cooling the water.

use a push button to operate the bottle and it could bring temps back down whenever you want it to..

i dunno, i doubt it would be that much work.

check out http://www.mr2beast.com/RAWIC.htm
it uses the same idea, just a closed A/C system. has some temp data as well..

 

im gonna go with an air to water intercooler and use a heat exchanger to cool the water and ice in the water cell when i want it really cold.

I've heard the new Ford Lightning actually stores a charge off of the A/C line and then uses it under hard excelleration

Depends on where you run. The old-school salt flat guys run an air-conditioning system on their turboed cars. I set one up for my car, but I'm aiming at the 200mph club so weight and that whole 10-15hp loss isn't much compared to the benefit I get from a cooler (down to 30*F at higher revs) intake charge. Not to mention extremely detonation resistant. BTW I use R-134a.
