Early days yet Peter, I've never had an engine run cool from day one if it's been completely rebuilt. I'll see how it goes. Racing cars will have different setups, but a race system does not have to cope with the same stresses as a road car. A racing car is running at high revs all the time, with water pump pressure to match, and has air passing continually through the rad at high speed. In contrast, running for 10 minutes at 3000 rpm then stopping suddenly to queue for the Dartford Crossing or similar, where you can't switch off at idle, is a far more demanding test of a cooling system. You will not see a proper racing car sitting and idling for a quarter of an hour immediately after a race. Too expensive! They also get stripped down every month/week/day anyway.peterc wrote:Dare I suggest that a rad with slightly deeper core or marginally wider might eleviate future concerns and go un noticed as to its inaccuracy within such a brilliant build.
I assume the racing boys have modified theirs especially chucking out 400+ bhp

Evans does boil, Clive - surely all liquids do? - but not until over 180°C, by which point it would all be a bit late... but no, I don't have it in the Cobra at present, just 50:50 water and Millers ethylene glycol.
It's OK Nige, no need to apologise!
