hi could anyone please tell me if their is any larger rads made to fit a cosworth. the alloy ones look the same size as the standard one or do they hold more water.. i know people will have different views but just after a rough idea of which most people think works best. and are the turbo cooler rads recomended...? many thanks..

 

The Pro-alloy lads do a beautifully crafted 50mm one (standard is 40mm) . I will be doing some testing with this radiator on Friday, so will be able to report the results .

I don't run water-cooling on my turbo, as I personally belive that on tracks it puts too much heat into the cooling system. However, it is essential on the GT range of turbos, so if you have one of these, the pre-rad is defo worth fitting .

 

will the rad cool better than the original though.. the car dont run over hot but sitting in traffic the fans come on but dont turn off till the engine is switched off

 

The sierra deisel rad is bigger, ie deeper, holds more water, and bolts straight up,
i dont no if the standard intercooler can be used, becauce the rad is a lot taller
although it is an ally rad it still uses plastic end caps.

 

I use the proalloy one that Mikes was going on about. I NEVER struggle with watertemps. Its the BOLLOCKS. on track even with a watercooled GT35 Turbo I was only seeing temps around the high 70's!

 

i have a pro alloy rad which is bigger than the one in porkies picture

well its the same size but i have badboy big end tanks on mine.

my stat opens at 88 degrees and my defi only ever goes above 90 when in standstill traffic

allway stays arround 88
