I have 2 main questions on low temp thermostats that no one seems to have the answer to. Thanks in advance to anyone who has answers

1. What is the effect of lower temperature thermostats on the engine's performance? I have seen dyno tests that show that the colder the coolant is the more power the engine makes, but I also seen tests showing that engines make the most power when fully warmed up, so a low temp thermostat could be counterproductive.

2. How would a lower temp thermostat affect the engine's longevity? I have seen companies claim that their low temp thermostats help reduce wear, but I would think that the engine's longevity could be adversely affected by running cooler than it is designed to run.

just run the oem one, you're never going to see any sort of benefit

So no increase in power from running cooler?

Not at a basically stock power level

Thank you. What would be the effect on the engine's longevity? Would the engine wear out faster running a little cooler than it is designed to?

You're worrying about a non-issue
