One or two other things I have noticed is that the water temperature seems to run very cool at between 70 - 80 degrees, which seems very low to me, and has anyone found a dimmer for the instrument lights yet?
It seems to be nominal:
cf page 27 of Cosworth information handbook:
http://www.atss.planet.ee/kolaladu/ford/Sierra-escort/cosworth_yd_information_handbook_1_0_(web).pdf
"Thermostat is a conventional manual device with a 82°deg set point. It is entirely normal for the thermostat to open at lower
temperatures whilst at high engine speed in order to maintain sufficient coolant flow through the engine."
An other remark, all the power charts have been done with a 70°C coolant inlet temperature.
