Does this have any electronics or pipes or anything? Or is it a big piece of metal designed to cool airflow - with no electronics?

Still learning this stuff ;)

Sheesh ... have you tried googling?
http://en.wikipedia.org/wiki/Intercooler

Basically it's a heat exchanger similar to a radiator.
You pass the charge air from the turbo through it to cool the charge air down before it goes into the engine. For an air-to-air intercooler (most common type) air is passed through the fins to cool it down.

In real simple speak:
Think of your car radiator but instead of passing water through it to cool the water down you pass the charge air from the turbo through it.

Nope, no electronics. Just an inlet and outlet pipe for the air.

EDIT: Looks like you beat me to it, Paul.

Would an intercooler add any gains?

Or is simply to reduce air temprature to get the quoted output?

Quoted output? Power? What are you even asking?
Seriously, just go read the wiki. All your answers are there. But in short, cooler air equals denser air equals more oxygen for combustion equals the ability to add more fuel to the mix equals more power being generated.

I'll read wiki now.

What I'm actually asking is when a car is rated (ie 150KW), the manuafacture is using ideal conditions, ambient temperature exactly to each that 150KW.

When it's hot outside, the air inverse of everything you said is correct and the car may only generate 140KW.

If I add a large, double capacity intercooler that cools the air, would I go to 150KW again or could there be a gain when fitting ie 155KW? If I go even better, more expensive intercooler - could I generate 165KW?

In a nutshell is it a performance upgrade

Yep...lemme give you some of my knowledge of turbo cars...I've never driven one, only been in a BMW 1series 325i turbo, but I"ve been researching these things and asking questions and talking to those who know since I was 17! Ok, long story short...

The Big @ss turbo spools up, compresses air...compressed air heats up very quickely...this hot air passes through an intercooler (made up of rows and cores) and it gets cooled down as the name suggests...now the air is colder thus more denser...this then get's pushed at remarkable speeds into the intake and gets mixed with feul and this cuases the engine to produce MORE powa!!!

Dude this ALL depends, getting colder/condensed air ALWAYS makes more powa...why you think at reef people's car's go faster...thinner air bro!

So yes, it will give you more powa, how much is a bit more technical, and you can have the biggest intercooler but this won't mean anything, will jsut mean air takes longer to get into the intake lol...intercoolers are mated to the engine specs...there's method in this madness, unfortunately the guy who tunes your car will know more:D

Dolby, I guess it would depend on your engine's fuel mapping, but yes, your car's sensors SHOULD pick up that there is excess oxygen that isn't being burnt and then add more petrol which in turn would generate more power. I can't really see why a manufacturer would prevent this from happening, unless there are concerns about running parts out of spec, but it's not like you're swapping to a massive turbo which doubles the power on the motor, it's only an intercooler. It'll be better for your engine life as well, by the way.

which one is that. is that the new BMW?:D

No that E46 Compact I think they called it...I still like those cars, and 325ti's go for under R100 000 nowadays. Anyway lemme tell you guys about that car. A friend in Kimberley bought it from a farmer in Upington...Rob Green did all the work on the car, it ahd a small turbo and was running 0.5 bar boost. The car had all the bells an whistles like t'vs and sound install and a body kitt it looked really classy, which was ever more worrying why this dude's dad bought him a car like this with this powa...anyway it went very well, really got me hooked on that BOV sound!

Needless to say, weeks afterwards the laaitie wrote it off...He didn't know ***** about a turbo car let alone a rear wheel drive!!!

What do you mean am I sure? A 325ti with a turbo by Rob Green...or are you insinuating that I'm insinuating that the Compact came out with a turbo from the factory?

I thought you meant from the factory?

So aftermarket?

From the factory those put out a puny 141KW from a 2.5 engine and a high acceleration of just over 8.5 seconds ....

Bigger intercooler = more lag, that's the primary reason manufacturers usually don't go for too big a intercooler, and a bigger intercooler in itself can increase power.

Ambient temps do make a difference but not much. Reason being that the air temperature after it's left the turbo will be 100's of degrees Celsius, especially when the car is hot.

The only reason you'd see 10kW increase at the reef is because they sell 95 octane standard, Highveld is 93 octane and Turbo engines are especially vulnerable to knock (Turbo engines don't take knock very well, usually it'll burn a hole in the piston, blow the head gasket or something similar). So the ECU will decrease boost and/or ignition advance in order to prevent knock (resulting in lower performance).

Yes...I thought you'd think that as i did too, why would they name it TI anyway?

Yes it was a rob Green conversion, but it was a small turbo, and the fact that you could feel the sideshafts knock everytime this dude used to change gears with the traction controll on was alarming...ever had that feeling that you can feel there is too much strain on a single component in the drivetrain?

Lol Im sure you think everything with a "T" means Turbo!:p

The intercooler does add some power to the car, but its relative to the engine, if its to big or to small you might lose power. If you put bigger turbo, you would need a bigger intercooler.
Some Brazillian dude added a K04 turbo(new S3) to his Polo but the standard intercooler wasnt upto scratch so he replaced it with a Ibiza 118kw and he made mad power!!
