Intercooler question
Okay, here goes,
what's the main difference between air cooled and water cooled intercoolers?
Is a water cooled intercooler more efficent than an air?
Is the water cool using regular water with ice or another liquid?
Is it possible to just submerge your air cool intercooler in a 2 1/2 gallon fish tank and mount it in the engine bay? If so, will the condesation of the air inside the intercooler be a problem for the engine (when not running)? Or would the air flow be sufficent to evaporate the condesation?
Any insights would be greatly appreciated. Am thinking of water cooling vs air cooling.

the water-air works really great for the first few mins. then the water gets too hot and it's worse then an air-air. great for drag racing. sucks for street.

Water to Air are perfect for Drag racing due to the volitle temps when the ice is placed inside the tanks. You can use it for the street but you will need to stop off at your local 7-11 for a refill....
Air to Air are basicly the best for street. The temps are pretty much static, dependant on the outside temps. You can use the water spray method used by Subaru on their WRX. It shears with the air to lower the temps. That should be more ideal.

Think about it...
If you're thinking about heat exchanger for the A2W, then eventually the water will have gathered enough heat to become the same temps as the hot intake temps - remember, most A2W IC's have very small cores compared to an A2A one.  If you're thinking about running an A2W IC through a pump then into another radiator outside, all this ends up being is a fancy A2A IC with more things to break - thus the reason I said A2W IC's have no place on a street vehicle.
Drag racing, yes - this is basically the only way to get below-ambient intake temps over an A2A IC.  You can even apply this to some very limited "sprint" racing, where you can calculate the water/ice mixture is enough to cool the A2W IC for the very limited race periods.

Another example of British motor car engineering at its best. Can you say "Lucas" without getting a bad taste in your mouth?

Yes, I used to put my hand in a vice, cause it felt so good when I stopped.

Come on, the engine is interesting, and it has a lot of "pretty" plastic housings, but not that complicated. A 3rd gen's engine is more complicated than that.
Sorry to hear your friend got a lemon though.

actually, its his second XJR lemon. The first one would stall randomly when the car was at normal operating temperature. Actually, 3rd gen motors are cake. I would work on a 3rd gen in a heartbeat. The XJR has those lame *** electronic throttles that seem to go bad.

Maybe you should go ask the Jaguar engineers why they did that?

Yeah, the SC defies all laws of physics and compresses the air without heating it.

Oh my... anyways...
The Vortech system for Civics and the like utilize an air-to-water "aftercooler"......
Unsure on how that works, but it's obvoiusly not designed for quick drag races, since it is a street setup.

apparently (i havent driven it that long) the jags cooler does heat soak and the only thing you can do is park the car for an housr or so. in normal driving you dont notice the heat soak because the 370hp car will intermittantly have about 50hp, or randomly go into neutral. its a sorry state that the flagship car in the jaguar (ford) lineup, has been to the shop 4 times in 6 months and it needs to go in again. the intercooler heat soak is the last of this cars problems

I think in theory a water to air intercooler is more efficient than an air to air because water has a greater ability to absorb heat than air does, but in reality I don't know. It does have advantages, like not restricting airflow to the radiator and to be able to get air temps below ambient (in theory). I tried a converted Rx7 intercooler on my Rx2 (due mainly to space restrictions) for a while. Considering it wasn't specifically built for this application, it worked ok on the street, but I could've made a cup of tea with the water after 4 laps of the track Plus i had trouble keeping pumps up to it.
