hve a full width airtec intercooler with twin fans at the mo wit standard rad,it runs round the town rather hot, just under 3/4 on temp gauge9thats with twin fans on) the standard radiator does not sit flush with the cooler but i herd that alloy ones bolt onto th cooler ? will this cool the rad down more ?


thnks sean

 

yes it will.

 

for sure! but is not cheap

 

i have exactly the same problem mate, same airtec cooler. im thinking of getting the airtec rad ready for summer. just out of interest how is yours set up fan wise.

mine is fans, cooler then rad.

ben.

 

yes and no,it will keep your temps cooler but once its warm it will take longer to disperse the heat
if youve probs with temps then an alloy rad is not the solution,look elsewhere in the coolin system

 

I've got a Pace Ally Rad'


Been told Ally dosn't make a great deal of differance overall

 

on a s2 you could get rid of your watercooling of the turbo, that is really going to drop temps! S1 has no watercooling on the turbo, so is possible

 

mines is exact same mate,tryed so many times but failed to fit the fans in the middle to cool th rad down

 

Last year I was running a Pace ali rad, my cooling was close to the limit. But wear and tear on the rad meant I had to replace it.
This year I have a new GRS ali rad and the cooling is superb.

Conclusion - a fresh, clean uncontaminated rad will improve the cooling no end.

Also if you remove the water cooling from the turbo it means that a lot of heat will be passed into the oil system.

could this increase charge temps too?

 

The S1 was designed to run without water cooling to the turbo, while the S2 was designed with it.

I haven't seen clear evidence of an Alloy rad cooling better than a new standard one.

 

Yes it could.



Also as C&B says a good standard copper rad is more efficiant than a good ali one due to the ability of copper to transfer heat better than ali. Ali ones are stronger than copper ones.

S.

 

for seeeeeeeeeeeeeeeeeeeeeeezzzzzzzzzzzzzzzzzzy!

 

Simon - the copper may conduct better, but what about the brazing

anyway, as i said before - it will improve things, simply because your existing rad will be shitted up nicely.

 

Do turbo coolers make any difference?

 

get a new/recon rad . surley reaching3/4 on your temp gauge aint good. seems v high to me.

 

I ran my car last year with a non-turbo bonnet (i.e. no vents) and still had no issues with temps.

Brand new good quality OE rad, or a recore is what I suggest.

 

OE rad ? whats tht mate ? cheers

 

Original equipment - standard

 

ah i c haha

 

fans should be between the cooler and the rad...
