Three customers have said the same thing, their cars aren’t consistent. Michael took one out on the road with a data logger on it. The water temperature was fine when he left the workshop at 85 degrees, but the temperature dropped and dropped – the guage stayed at ‘normal’ – but the water temperature dropped to the point where the temperature corrections kicked in and would reduce the power. One good pull and the temp was back at 80+, next pull and full power. Drive a bit and the water temperature dropped to 60 degrees, the mixture richened up, the ignition re****ed, boost reduced etc etc. The engine thought that is was warming up. The inconsistency that we had heard about. It would not have shown on a chassis dyno. So we investigated the thermostat.
