How does the water to air intercoolers work? (more inside)
 

In the winter, do you put anti-freeze so it doesnt freeze up? What about the summer? What do you do ? Just wondering

Ask WJM on the A4 forum...
 

In the winter an antifreeze/water mix. Summer you can use less or no antifreeze.

Water is much more efficient at removing heat, but there is a fixed quantity of water in the system so you need a separate heat exchanger/radiator to remove the heat from the water.

2 types of air to water iirc. not sure of the names
 

1: (homemade)its just a regular container that surround the intercooler with a cap. you drop ice and water into it when you are at the track. this IC is NOT good for street use

2: radiator type IC. the IC has air actually passes through a rediator type device that has its own closed circuit fluid. the radiator has 2 cores. one inside the IC, and one at the front of the car to cool the liquid.

basically the A/W IC either does or doesnt have a heat exchanger. it should be a closed system in
 

all cases. some do have provisions for a 'dry ice' box to drastically cool the water/coolant.

some dood around me with a 9 second lightning showed me his homemade a/w IC
 

dry ice box the size of 3 batteries.

Is anyone running A/W IC on here?

the silverbullet ran air to water, theres a black avant around with AWE air to water ICs back from
 

when they made them too.

How does theres work?

closed system, modded stock ICs with a 'water jacket' welded around them, completely enclosing them
 

with water. heat exchanger for the system mounted in front of the radiator.

And awe sold that whole setup? How much? why did they stop?
