What is the ideal water temp during a race? My tr3 was running around 200 deg. Sometimes 205. It was 95 outside and I had NGK BP8 plugs. I seem to remember running about 10 deg cooler last year in hotter weather. This new motor has a higher CR than the last one. It didn't overheat, just seeing what temp is ideal.
