Guys,
I have a radtec (45mm) core radiator. The cooling is fine when on the move but as soon as I hit traffic the temp climbs quite quickly to 88/90 deg. The fan then cuts in, but if it's a warm day, the temp will climb, quite slowly up to 100 deg +. A recent enforced rebuild left my engine builder advising that he would like to see the motor run cooler when being worked hard or stuck in traffic. i dont do alot of miles but I did get caught in a terrible jam around brussels last year which saw me pulling over a couple of times due to high temps. (I was runnning the 82 deg stat)
So, what are the rest of the Vx modified owners seeing as temps?....which Radiator are you running? I would appreciate some feedback as to what temps you are seeing in normal road/traffic use?
Spoke to Radtec today...they have stopped making the caterham extreme radiator (was 68mm core) and are now making a 58mm model which they feel would suit my purpose.
I am getting hot water in the expansion tank and the rad hoses are nice and warm when i close up the system.
comments appreciated...
