We know, just didn't see the point in answering the question.
its down to the design of the cores, inter's airways are alot larger, to allow alot more flow in a short space in time.
And a rad, just would just cause such a large resriction, and pressure drop.
And a inter hasn't got enough bars to be effient as a rad.
i've never tried it, nor going to, but its quite easy to see, if you look at the cores.

As above. It's just pointless.
Like asking if you can use a Turbo instead of a heater blower motor. Why bother?
Radiators are designed to carry water, Intercoolers are designed to carry air.
I sat in traffic this morning for 25 minutes, ambient temps around 20°C and never saw the temp gauge go over 1/4. I just don't see a problem with the standard rad. Problems are casued more often than not by other aspects of the cars spec, such as airflow, fan set-up, radiator condition etc.......

Though I imagine my IAT's were no higher than 30°c, from past experience.

i havent said it is better in any way!
and yes it is pointless!
but as all of you just avoided answer direct on my question
so you could use a IC as an radiator!

Just been out, and measured a S1 rst rad (still on s1 car)
End tanks = 700 x 320 x 55mm (Hieght = 400mm if inc mounts)
Core = 595 x 290 x 30 mm
Xr2 O/A = 605 x 360 x 50mm
core = 495 x 305 x 35 mm
Are S1 and S2 rads the same?
if so i'll fit a ERST rad. How much are they new?

No they aren't
Series 1 rad from what i remember is still the same same although it looks a lot bigger.
Nothing identical between them though.

well.....when i was enquiring about rads when i converted mine, a S1 rad looked to be much larger in size, but the place i use showed me their lists and apparently the cores are the same size size yes 
Wasn't convinced myself but i dont have a Series 1 rad to compare.......looks to me to be the same length/width as the 3i rad, but with relocated brackets to shove it across to make way for that piss poor excuse for an IC which they conventinetly placed behind the headlight

i measured a S1 rad today (the measurements i posted earlier) which is fitted to a S1 RST on my drive.
if you could measure your S2 rad please, then we're know.

Went to a Rad retailer yesterday, and went thro his stock and booklet, to find best rad.
Come away with 2 options, 84 xr3i rad, or a 2.0 sierra rad.
the sierra rad was taller, but would need car mod's to fit, and as the extra hieght is stuck behind the front panel, i ordered a xr3i alloy core'd rad.
Even tho i used to think copper core was better, but i've had 2 new xr2 rad's on my car in last year, and the alloy one was alot better for trackday temps, and the copper item gets hot whilst top speed runs, which the alloy item didn't.

i have also a erst as a trackcar. And on those shiny summerdays (rarely these days ) The temp meter used to go redline. However since i've ditched the heat excanger, and put on an oiltakeof to a 13row oilcooler, temps really dropped into the normal zone
For me the oilcooler setup came across, and did not cost half of what a new (alloy) rad would be.
Oil is now also safely below 115 degrees Celcius. ( So i won't have to change (burned) oil every trackday.

Whilst we are on the cooling subject. Could someone explain what benefits a swirl pot would have to a cooling system.
I used to have one on my 1.9 setup but now have a full zetec steup without a swirl pot.
Would it be of benefit to put one on?

Swirl pots are designed to remove any air bubble's which in turn stop's hot spot's.
The new rad come, but it was in Copper recon item, so i decided to get the Alloy Sierra item, and modifie the car to fit it.
I've also noticed AirTec have now brought out a S1 rad, which i have emailed for the size of the cores. but does look wider than thier S2 item.
S1 Ł200

S2 Ł200

I believe the hottest point is the best place to take a reading, as long as its not getting heat soak from the engine.
