I pulled the temp sending unit and checked it with a calibrated thermometer it is dead on from 100C to 70C/155F. Going down the freeway tonight I got the temp down to 70C!!! or 155F. Thermostat is for all practical purposes useless. By the way it is a new 195F!!! Optimuim engine longevity would be from 85C to 100C.

I guess I play the same trick as I did with the oil cooler and install a piece of plexiglass on the bottom 1/3 of the radiator. I have no idea where all the circulation is comming from the thermostat has to be closed at 155F. Is is possilbe the water pump bypass is causing the circulation??

Coincedentally someone on the FE forumn has the same issue, we are all wearing our engines out prematurely. Next cobra I will do the engine and trans installs since I have to figure out all the solutions anyways LOL!!!
