I’ve just ordered a selection of resistors to experiment with if you want to hold fire on forking out on a gauge just yet?
I can let you know if they make any difference or not. With mine, I’m still using the series gauge and sender but it now reads much higher than with the 2.25 which used to sit in the normal range.
With the V8 it sits just under the red line at normal temperature so I’d like to bring the needle down a bit but still allow it to rise if the engine gets hotter and the fan kicks in.
I’m not even sure if V8s run hotter internally than a standard engine??
