170 Thermostat?
"...Years of research show use of 160 degree thermostats is way too low to be considered for performance or engine longevity. As the chart above illustrates, engine wear increased by DOUBLE at 160, (~30% @ 170?) than at 185 degrees. The 160's were invented for and commonly used in older, open loop cooling systems where only 6 pound radiator caps were used, and low 212 degree boiling points were the limit. We know better now.
Many early hot rodders found the 160's to be a smiggin better (~5%?) performing than the 190's, however the in between 180 appears to satisfy both ends of the spectrum. The correct water temperature and thus resulting metal operating temperatures required for the cylinders to achieve a minimum specific temperature in order to allow a fully mixed Air/Fuel charge to combust efficiently is a minimum of 180 degrees coincidentally. If you use 160s be aware that this can have a degrading effect over a time on your engine.."
HOTRODSRJ’s COOLING TIPS Operating temperature vs power and longevity!
The term efficiently means complete combustion, ie. without loss. Hard to find a graph that actually shows the power difference in HP instead of the Delta of 12.6 (p) and 14.7 (e). These graphs that are published would make more sense if the data points were available too.
