Hi
Ford ran the engines at those temps for emissions not best performance which is attained at a far lower temp.
Cheers Matt
So what temp is best for performance then ?
High cylinder temperature is best for efficiency and power BUT is limited by pre-ignition/knock and the temperatures
the materials in the engine is made of.
Ideally for maximum power you would want the incoming air and cylinder head relatively cool but the cylinder liners as hot as the pistons and
piston rings. will.tolerate.
A few engines have been built with the cold coolant entering through the top of the engine and hot coolant exiting from the bottom in an attempt to
maximising both combustion and cycle efficiencies but it brings too many potential problems and demands a bigger power sapping water pump.

One final question, best position for the fan, the car came with it positioned behind the rad, is the best place for it or is it better in front?
Depends entirely on the design of the fan and ducting.
