W2A intercooler? Thaughts

[CelicaGT8]

Heya, look at my Corona link at the bottom, go to the recent stuff.

Im changing my intercooler, probably go for a w2a. hav a st205 on in the pics, also have a legacy one, but have hurd they are rubbish?

Cant really put one on top of the engine due to the extracters etc not to mention the intake manifold (not the standard way anyway) and i like getting at my plugs easy.

Any input would be great

The ST205 ones are better, they have bigger water lines to them, and the heat exchanger is bigger than the Legacy one.

ive always wondered, how do those sorts of intercoolers work?

man, what a sweet intercooler you have there!

They're pretty simple really, they have water flowing across the core instead of air(which is why they're fully enclosed) and a heat exchanger in the front of the car which dissipates the heat

As its a race car ditch w2a and just get a frount mount. The reason being is that the typical W2A intercooler is more about absorbing the heat generated by a decent run through the gears, dissipating some of it whilst heating up, but getting rid of most of it after the pedal has been released.

That is not entirely true.
A good W2A system is well capable to dissipate continuously. The dissipation depends on the radiator, and if the radiator is of the sufficient size (eg stock ST205 is plenty sufficient), it will dissipate continously.

Although W2A system will run slightly hotter, the temperature will be more consistent, as well as W2A system has higher capacity to buffer the spikes than normal A2A system. It takes much more energy to saturate 1 kg of water versus 1 kg of aluminium, you also get a lot more water in W2A than aluminium in A2A.

The aluminium to water transition is more conductive than aluminium to air. You could have a lot greater surface area on the radiator, without having to deal with lag on the W2A system.

There are many advantages in W2A system for all uses, except perhaps in situations where there is continuous air flow over the intercooler.

The main disadvantages in W2A system are:
1) Cost
2) Weight
3) Complexity

The advantages are:
1) Efficiency
2) Consistency
3) Lag

So you need a standalone radiator on the front of the car is that correct?

[Dell'Orto]

Yup

[MAGN1T]

All you really need is 2 old air to air ICs. (or in my case, 4)

One you mount up front, modify it to take water fittings. Fill it with water (antifreeze) The other you mount in the engine compartment, the air from the turbo goes through it. Mount that one in some sort of sealed box with water in it. Then all you need is pipes and a pump.
As to how you manage to get it to work, like everything else, it's up to your imagination.

In theory, if using W2A with a modded A2A core it is best to fill the A2A core with water and run the intake air across the core. Or so my research leads me to believe anyway, don't know whether you would notice the difference.

Had a front mount, but due to the length of the pipe and partly the size i chose it had a sh1t load of lag. my head hurts
