I preferred the performance on cough syrup (80/20 FAI fuel) and a full wave pipe.

I will say I never used a thermometer to tune my race engines. The tach and stop watch were to best tools I had at the time. Now I did use a thermometer during the development stages of the engines. (No, I didn't have these neat hand held infrared things of today.)

Again as has been said by me and others the actual reading is of little value. Tune your engine for the best performance using a tach. If you then feel the need to know the temperature take a reading at this point and record it for future reference.
