It occurs to me, being a race tech that heat and subsequently air is absorbed 8 times more by water than by even very cold dense air. Hence a chargecooler being more efficent in a purely mathamatical sense. As legacy's have chargecoolerswhich are reasily available and cheap, around £120 all in is there anyreason as to why this wouldnt be more efficent than the standard intercooler on my 95 wrx?

I believe the pipework (may be something other than pipework) makes it too restrictive to actually offer any advantage.

What are you going to do with the heat once it's in the water?

A second rad laid flat under the rear of the car with ducting to suit was my idea

And where precisely does the heat go from the radiator?

Fuzz

out of the back of the car along with the rest of the air, if ducted correctly.

If the exhaust is in the left hand rear then rad can go in the right hand side, a bit like gearbox oil coolers, although a bit more hefty.
I'm sure a decent rear duct taken from say the rear wheel arch to feed the rad and then exited via the vacuum effect of groundforce...

I've jut written all that and now think you are getting at the fact it's back to air doing the cooling..
As long as the rad is more efficient (due to being larger) than the (small) charge cooler.......
Anyway I better get up and go to work or. I'll be late.

We had this discussion recently

You're going to need an awfully big water tank if you're pissing it all out the back

Already discussed at length.

He is saying that you should be able to increase the efficiency of the size restricted I/C using water, then cool the water with a larger remote rad (as you are no doubt aware )

Seems marginal to me, However the Toyota GT4 ST165 and ST205's used charge coolers though the ST185 did not.

Surely on the move, more than enough air is coming in an STi MY03 scoop to cool the I/C core.

aight, just a thought, i did the maths on it but just wanted some real world thoughts on the matter. thanks.
