Many years ago, I developed a racing engine at great cost. Because the radiator was behind me and I couldn’t see it or be aware when the water temperature was too high, we put in system to stop us blowing the engine up.
It went as follows
From a take off from the thermostat housing we fitted two sensor devices, one was hooked up to a large light on the dashboard (Actually it was a side light off a Mini) this would activate when the water temperature reached a certain temperature, the second sensor was set at just below boiling point and this was hooked through some sort of relay ?? and this would actually cut the engine off. I didn’t fit this system, an excellent local company completed it for me. They were the sort of company which specialised in car electrics and even repaired starter motors and alternators. Unfortunately, they have retired the business and are no longer available.
Before I take the VX onto track work I would like to find somebody who would develop this type of system for my VX. There may even be a commercial system in place.
Any help would be appreciated
